    Jammie Dodger Blondies

    Jammie Dodger Blondies

    Jammie Dodger biscuits are one of my favourites, I remember eating them as a child and always picking them first out of biscuit selection boxes. If you're not from the UK, they are a cookie with jam sandwiched in between two layers of biscuit. They have such a fun appearance - with the splash effect on the biscuit and heart shaped hole revealing the jam in the middle. It's no wonder they are the most popular kid's biscuit in the UK! I've incorporated yummy Jammie Dodger biscuits into these soft gooey Jammie Dodger Blondies, as well as adding some extra jam (because that's the best bit!) If you've not heard of blondies before, they are the white chocolate version of brownies, and if you enjoy these you'll love my Raspberry & White Chocolate Blondies too!

    Jammie Dodger Blondies

    Ingredient Tips & Equipment Information

    • You can use either butter or a baking spread for the blondies. I personally prefer butter.
    • Avoid using cooking or baking chocolate for the blondies, and also I don't recommend using Milky Bar or any white chocolate with low milk solids as they can stop the blondies from setting.
    • If you don't have golden caster sugar, you can use regular white caster sugar.
    • I used Callebaut chocolate chips for this recipes, but any bake stable chocolate chips will work.
    • As Jammie Dodgers are raspberry flavoured, I've used raspberry jam in this recipe. You can swap it for strawberry if you prefer, or any flavour of your choice. I do recommend using a good quality jam.
    • Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
    • For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.

    For the full recipe with measurements, head to the recipe card at the end of this post.

    How to make Jammie Dodger Blondies

    Start by melting the butter and golden caster sugar together in a pan on a low heat. Once the butter is melted, take the pan off the heat and add the white chocolate. Leave it for about 5 minutes, then stir it until the white chocolate melts into the mixture. Add the eggs and vanilla extract, and whisk them in. Then add the flour and white chocolate chips, and mix them in.

    Pour the mixture into the lined tin and add the jam in small dollops all over the top. Use a butter knife to gently swirl the jam around.

    Place the Jammie Dodger biscuits on top, the bake for 30-35 minutes or until golden all over. Leave to cool in the tin. Chill in the fridge for a couple of hours, then remove from the tin and slice.

    Jammie Dodger Blondies

    What is a blondie?

    Blondies are essentially the white chocolate version of brownies. They are fudgey traybake treats with white chocolate melted into the mixture for extra gooeyness.

    How do you know when the Jammie Dodger Blondies are baked?

    I bake them in my oven on 160C Fan for 30-35 minutes until they are golden brown all over like in the photos. Using a skewer inserted in the centre doesn’t give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down, wait until they are cool to remove them from the tin. I also recommend chilling them in the fridge for a couple of hours before removing them from the tin and slicing them.

    Can you make this recipe without Jammie Dodgers?

    Yes! You can make this recipe without the Jammie Dodgers, or you can use any other jam filled biscuit or linzer biscuit. Or you could even make your own homemade Jammie Dodgers, there are lots of recipes available by doing a Google search. Or you can use my Homemade Jammie Dodgers recipe!

    What can you do differently?

    You could use mini Jammie Dodger biscuits if you wanted to cut the pieces smaller. I like to give everyone one Jammie Dodger biscuit per piece. You can use different flavours of jam for example strawberry, raspberry, blackcurrant or cherry. I've also made these before using Lemon Jammie Dodger and lemon curd!

    Jammie Dodger Blondies

    What white chocolate should you use?

    The majority of times I make this recipe I use a supermarket own brand white chocolate (not the very cheapest kind, but the level above) or Callebaut callets, if you use a better quality chocolate, like Green & Black's for example, it will improve the flavour. But of course supermarket own brands are great for keeping costs down. I would advise avoiding cooking or baking chocolate, and also I don't recommend using Milky Bar or any white chocolate with low cocoa solids.

    How long do the blondies last for and how should they be stored?

    They will last for 3 days and they are best stored in an airtight container in a cool place.

    Can the blondies be frozen?

    Yes, wrap them well in cling film or store in an airtight container, and freeze for up to 3 months.

    Can these blondies be made gluten or dairy free?

    Making these blondies gluten free is easy! All you need to do is replace the plain flour with a gluten free plain flour blend. You may also like to add ¼ tsp xanthan gum for better texture. You will also need to use a gluten free alternative to Jammie Dodgers. I haven't tested this recipe with dairy free ingredients so I can't say for certain that it will work. Please do check the labels for everything you use to make this recipe if you are serving it to someone with an allergy or intolerance.

    Jammie Dodger Blondies

    What size tin do you need for this recipe?

    This recipe is for a 9" square traybake tin, you can also make this recipe in a 12" x 9" traybake style tin, they will take less time to bake and the blondies will be a bit thinner, but still yummy.

    Do you need an electric mixer to make the blondies?

    No, in fact I recommend making the blondies by hand with a whisk and spatula. It's so easy to do and you can mix it all together in one bowl or in the pan (which is what I usually do to save on washing up!)

    More tips for making the Jammie Dodger Blondies:

    • If you can't get hold of golden caster sugar, you can also use regular caster sugar (also known as superfine sugar).
    • The blondies can be frozen. Once fully cool, wrap them well and freeze for up to 3 months.
    • You will get better results if you use a good quality jam

    • Melt the butter with the golden caster sugar in a pan on a low heat
    • Once the butter has melted, take the pan off the heat and add the white chocolate. Leave it for about 5 minutes, then stir together until the white chocolate is fully melted. Don't worry if it looks a bit lumpy or separated
    • Transfer the mixture to a mixing bowl at this point if you like. Add the eggs and vanilla extract to the mixture, and whisk to combine

    • Bake the blondies for 30-35 minutes, or until they are golden brown all over. Using a skewer inserted in the centre doesn’t give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down
    • Leave to cool in the tin, then put them in the fridge for a couple of hours. Then remove from the tin and slice

          I made the blondies , followed the recipe exactly but when I cut into them, the middle section was very raw and rubbery and tasted a bit eggy even though I did everything correctly... why was this?

            Hi Victoria, I'm sorry that the blondies didn't turn out how you expected. It's hard for me to say exactly but many things can affect how a recipe turns out. The brand of ingredients used, the temperature of the room, the material of your cake pan, the altitude of your town and every single individual oven can be slightly different. It sounds like they might have needed baking for a little longer so perhaps you could try that next time or use a slightly higher oven temperature. Do check that the centre isn't too runny before taking them out to cool. Good luck!

      Mmmm, I absolutely love this idea Kat! Jammy Dodgers were always on my radar too as a kid though I didn't appreciate that they are still the most popular biscuit to kids! Great idea to inclide extra jam too Kat, I can just imagine that your blondies were so yummy and v popular 🙂 Thankyou too for joining in with #BakingCrumbs,

      Most of the kids I come across these days seem to prefer chocolate biscuits but I know several adults who would crawl over broken glass to get the last Jammie Dodger in the pack. I know that they'd love these.

        Hi Anisha, they are not meant to be like biscuits, they are blondies so the texture is supposed to be gooey (the same as brownies are). If you mean gooey as in not fully baked - what size tin are you using? If your tin is smaller they will need longer in the oven as it will be a deeper mixture. Is there anything you are doing differently, such as changing any ingredients?

      So disappointed, as above these come out far too gooey. Used the correct sized tin and even baked for longer than stated but they were still almost liquid in the centre once cooled. Such a shame as they do look amazing. I will have to find another Blondie recipe and adapt.

      Just sliced into our batch of blondies (4pm) after making them this morning and I'm so happy that we picked up a couple of packs of Jammie Dodgers from the supermarket. They're so lovely and fudge-y - just like a blondie should be - with a great contrast in texture from the Jammie Dodger biscuits. I didn't have the same size tin you used so tried it with one I make my swiss rolls in (11.5" x 7"). They were perfect. Will definitely be making them again. Thanks for the recipe.

      Please help! I made these today and the taste is absolutely delicious but they were completely liquid and would not set, only the very edges were not runny. I only substituted the sugar for light brown sugar and followed the method exactly, same sized tray bake tin. I ended up putting them back in the oven several hours later after cooling as they were inedible, after another 30 mins in the oven they were still liquid. Any advice on what to do would be great as I’d love these to work, the taste is lovely. Thanks

        Hi Angela, I've had a couple of comments saying the same thing (but then also several comments saying they worked fine) and I myself have made them at least 4 times and have never had a problem so I'm a bit stuck on this issue to be honest! I don't think changing the sugar would have this affect. Is there any chance you missed an ingredient? I would recommend getting an oven thermometer too, to check your oven is at the right temperature as sometimes the dials are not accurate. Mine is off by about 10 degrees but some ovens can be even more. I'm planning to make them again in a couple of weeks and I'll do a tutorial on my Instagram stories which will hopefully be helpful. I hope these go better for you second time round as they really are so yummy!

          I think I might have an idea!! If you swirl the jam in too much with the mixture it doesn't allow the mixture to cook properly! I'm going to make these again and make sure the jam just sits on the top!

            Hi Rachael, it's not the swirling of the jam that will stop the mixture cooking correctly (if you don't swirl it at all the jam could just sink to the bottom if it is in big lumps) but cheap jams set with glucose that can affect the bake. Another reason this happens is from people using Milkybar chocolate, or any low cocoa solid white chocolate, which I do not recommend using. I hope that helps 🙂

      I tried these today- followed the recipe exactly, using a silicone tray.. cooked for 45 minutes and still completely raw everywhere except for the very edges! I don’t know why! Didn’t want to leave them in for longer as the edges were starting to catch a bit.. I’ve made blondies lots of times with very similar recipes with no problem- I’m thinking maybe it’s the inclusion of the jam?!

        Hi Charlotte, it's probably because you used a silicone tray. They are not very good, I would always recommend using a proper metal baking tins. As you can see from my photos, YouTube video and also I've done a tutorial for this recipe on my Instagram stories, this recipe has turned out great everytime for me and I've made it around 8 times now 🙂

      I made these Jammie Dodger Blondies during a business enterprise week at the school I work at.They were very popular and sold out very quickly,I did the first batch without jam as we had forgot to buy it and they still were delicious and some people preferred them. I put jam and also used half white and half milk chocolate in the second batch as we were on a tight budget and the pupils could not get enough .I will be making these in larger quantities next time as pupils have already requested these for next year .We raised over £200 pounds and my group won ,and made more money than all the other groups put together. I would like to think these Blondies played a small part in that amount, the money has all gone to cancer research .

      Would this work without putting as much white chocolate in it? Id prefer to have a few chunks of white chocolate in blondies

        I've not tried that so I can't say for certain, I'd suggest adding some white chocolate chips in the mixture instead to get that effect 😀

      Just took mine out of the oven! Smells lovely!
      Same as per previous comments after the 30mins recommended cooking time the middle was still very much liquid so I put a sheet of foil over the top and left in for another 20 mins - fingers crossed tastes as good as it looks!

      Unfortunately this recipe isn’t working for me. As LOTS of others have Said my blondies cook on the outside but are liquid in the middle. I followed everything to the letter. Very disappointing 🙁

        Hi, I’m sorry that the blondies didn’t turn out how you expected. It’s hard for me to say exactly why they came out as you describe, but many things can affect how a recipe turns out. The brand of ingredients used, the material and size of your cake pan (a 12″ x 9″ tin is needed for this recipe) and every single individual oven can be slightly different. It sounds like they might have needed baking for a little longer so perhaps you could try that next time or use a slightly higher oven temperature. Do check that the centre isn’t too runny before taking them out to cool. Good luck!

          Not a great concoction of ingredients IMO, I would advise others to look for another recipe.
          I spent a lot of time and money buying the best quality ingredients for every part of this recipe and like a lot of others have mentioned, mine were raw everywhere except the very outside too.
          I decided I’d just put them back in the oven for an additional 20 minutes, checking every 5, on a lower heat with the top covered so they don’t burn and they just won’t cook.
          It’s not like a gooey loveliness either, it’s like I’m eating raw wet batter in between a cooked shell and it isn’t pleasant!
          Really disappointed 🙁

            Hi Arabella, I'm sorry to hear the blondies didn't turn out how you expected. There could be many reasons for this; changing ingredients, the brand of ingredients, using a different sized tin or a non-metal tin, not following the recipe correctly, your oven temperature. This is one of my fave recipes that I make reguarly, and it's had a lot of positive reviews, so unfortunately if it doesn't work right for you it does mean you're doing something differently to me. If you can let me know what you think this might be then I am happy to help you make this a success next time 🙂

      Mine have just finished baking - they look, smell and taste amazing!!

      I had the same problem as some others here with a very soggy bake in the middle. I done the first 30 minutes (actually done 35!) with the fan on at 160c so I wondered whether you normally bake at 180c without the fan, and perhaps that might be the difference people are having?
      Since they were not baked after cooling I ended up doing another 20 mins at 180c (no fan) and they seem ok now, albeit a bit over baked around the edges!

      Thank you for this recipe, I'm sure they'll not last too long and will be made again soon!!

        Hi Gary, I always bake at 160C Fan, but all ovens are different so as long as you've used the same ingredients, used the same size tin and followed the recipe exactly it may be a bit of trial and error with your oven. I hope you enjoy the blondies! 🙂

          You're absolutely right, it seems to be the oven. I can't cook this with the fan on as it's not cooking the centre in time. Fan off and baking for 35 mins is fine.

          I've made this about 4 or 5 times now - very addictive and not lasting very long!!
          A couple of times I've done it without the biscuits (and swapped the jam for Nutella!) and 30 mins is enough.

          Thank you very much for sharing this recipe with us all!

        They taste delicious, however even after baking for 45 mins the centre wasn’t cooked. My oven was perfect temperature,( use a thermometer) I think the chocolate maybe the issue. The outer pieces were so good. Will try again.

          Hi Liz, thanks for your feedback and I'm glad you enjoyed the recipe! I've never baked it for longer than 30 minutes (maybe 35 at a push) and it's always cooked so I'm not sure why this happened for you. If you used baking/cooking chocolate or Milky Bar then this could have been the issue.

      Super recipe! I bake atleast 4 times a week in my tearoom for the kids & have donated several batches to local events with great feedback. Perfect texture crispy edges and soft brownie like centre. Always a winner for us. For the people with the 'runny' texture complaint, a few things you should consider & try..

      Cheap jam that is set with glucose instead on natural set jam can put to much sugar in the mix & unbalanced the recipe causing it to not cook or cook slow.

      White chocolate with low cocoa solids & to much fat in can do the same.

      Because it is a with mix & looks raw,you can panic when cooking...it is suppose to be the goey consistency of a brownie not sponge cake or crunchy biscuit which then again may throw you off.

      Thankyou again,I love it!

        Hi Angelina, glad you enjoyed the recipe! Yes I know what you mean and it does look that way on the bottom, that is normal. They are essentially the white chocolate version of brownies, so they are meant to be very moist and gooey like a brownie would be, I hope that helps!

      Hi just wanted to let you (and other prospective bakers) know that I also had some issues with the Blondies being almost raw in the middle. Followed recipe to detail and had the same issue as a few others. The only thing I can think of that might have played a role is the white chocolate I used was not baking chocolate and therefore may have been too rich (high in fat) and so meant that there was just too much fat to flour ratio for it to cook and set. But I have no idea as I’m not really a baker! They taste lovely, just a shame they didn’t set. Only the edges were edible 😩

      Just made these. Easy to make and smell amazing! However cooked for 45 as used a smaller tin but ive just cut into them and they are still liquid in the middle. Trying putting them back in the oven to see if longer helps but they've already started burning on top so really don't know what to expect when I take then back out again. Rather disappointed as they smell amazing but are currently inedible!
      Okay, so after an extra 50 minutes in the oven they are a little crispy on the outside and the biscuit but they are amazing! Don't look as instagramable as I hoped they would but the smell and taste sure make up for it! I might try cover it in tinfoil next time and hopefully the biscuits won't burn. Also going to use mini dodgers next time as i feel it will look nicer.

A 12″ x 9″ tin is needed for this recipe, as you used a smaller tin this will affect the final result. I would suggest next time either using the recommend tin size, reducing the recipe by half or two thirds (depending on the size of your tin), or turning the temperature of your oven down and baking for longer. Good luck!

      I made these last week after enjoying a little lockdown baking and they went down really well. The recipe was easy to follow and they turned out lovely and fudgy on the inside. One point to note, I think I had a slightly deeper brownie tin so had to leave them in a little longer, I took them out when the outside looked golden brown and a slight wobble in the middle (as they continue you to cook when out of the oven for a little bit).

      Overall very yummy and thank you for sharing the recipe 😊

        Hi Leonie, I'm so happy these blondies are such a hit with your family! Do you mean the blondies stick to the paper? Once the blondies are fully cooled down, the paper should peel off easily. If you try to unpeel while they are still warm then you may find it sticks more. I use baking paper which is specifically designed to not stick, could it be that you're using a different kind of paper?

      These are delicious! Mine were still liquidy in the middle after 30 mins (not sure why, could just be my oven!) but left them in for a bit longer with tin foil over the top and they turned out great! It’s always hard to tell with blondies / brownies when to take them out as they do firm up when they cool.
      They were so yummy though and lasted less than a day! Definitely going to make these again

        Hi Leonie, so glad you enjoy them! I'm not sure what you mean by an updated version, I am super happy with this recipe and I wouldn't change anything 🙂

            Thank you! Yes there are a few versions around now, I guess the only way to know is to try them all - a delicious experiment 😀

      I made these for cake Friday at work and they were a great hit! Deviously gooey and chewy 😍

      I made these blondies (see @puneetbhachu) and I already want to make them again! They are so tasty, literally heaven in my mouth, and the recipe is so well written. Thank you so much the Baking Explorer, firstly, for perfecting the recipe and second, for adding the transitional images - they are super helpful! I added white chocolate of the extra indulgence, I highly recommend the addition but I may be biased! Thank you for sharing this beauty with the world, truly a joy to bake and even better to eat so I will definitely be making these again xxx

      Hi Kat! Thank you so much for the recipe I’ve got a very happy son and husband! 🤣 very easy to follow and my favourite part was I didn’t need to even get my mixer out (less washing up!) ❤️❤️

        Hi Gina, I have no idea sorry I've never made it in the tin your describing. At an absolute guess I would say 2/3 of the recipe, but as I say I've never tested this.

      Hi what ingredient quantities would you use for a 16 x 12inch tin?
      Thanks

          I tried these and they worked perfectly! I was wondering would it work if I used custard creams instead? So put pieces of custard cream in the mix and custard powder?
          Would I substitute some of the flour for the powder?

            Hi Charlotte, you could definitely use custard creams for the topping. As for swapping the flour for custard powder, I've never done this before so I can't say for certain. Maybe try it with a small amount to start with. Let me know how it goes!

      Hey would these work with a 12” x 12” tin if I increase the ingredients slightly? (I’ve used an online converter to adjust the ingredients) And do you know how much longer I would have to bake them for? Thank you ☺️

      The best blondie recipe I’ve tried. After many blondies fails with other recipes, I’m delighted with this one. Not only is it divine, the recipe is so easy and works perfectly. Thank you!

      I tried this recipe today and it is absolutely incredible! I adapted it slightly by using white chocolate with ginger but worked a treat, so tasty and so simple! If you want to see a picture I have posted one on @demi_devours_everything on Instagram!

      Super yummy blondies 😍. At first I thought I under cooked them so I kept putting them back in the oven but then realised this is how they are meant to be. They were very tasty and would definitely make these again, however I have so many other recipes of yours I want to try too. Thank you for your amazing recipes x

        Hi Coral, yes that's right they are gooey like brownies, it can be a bit confusing if you've not made many blondies before. I'm so happy you found them tasty and would make them again! 😀
