These moist chocolate Vegan Oreo Brownies are drizzled with some dark chocolate for good measure, the perfect treat! They are so yummy, and really fudgey, plus they taste super chocolatey and indulgent! Any Oreo fan is sure to love them, and they're so easy to make too!
If you're not a vegan then you might not know that Oreo biscuits are suitable for vegans. Yes that's right, those delicious chocolate sandwich biscuits are completely free from animal products! They are known as "accidentally" vegan, which is a group of products that were not made to be suitable for vegans, but by chance they are. This often happens because retailers use cheaper ingredients (for example oil instead of butter), so most accidentally vegan products are not exactly the healthiest of options! But hey, vegans need junk food too!

How to make Vegan Oreo Brownies
For the brownie batter put the plain flour, caster sugar, cocoa powder, baking powder and salt in a bowl and stir together. In a large jug, whisk up the almond milk, flax eggs, vegetable oil and vanilla extract.
Pour the wet ingredients into the dry ingredients and whisk it all together. Then pour the batter into a lined baking tray, and sprinkle over the broken up Oreo pieces.
Bake it for 35 minutes, then leave to cool completely. Slice up the brownies and drizzle melted dark chocolate all over them.

Tips for making the Vegan Oreo Brownies:
- I recommend using a serrated knife to slice the brownies as it is easier to saw through the Oreo biscuits.
- If you are serving the brownies to vegans, make sure the dark chocolate that you use is suitable for vegans (I used Green & Blacks 70%) Check the label, if it says 'may' contain milk then that is ok as this warning is for people with allergies and doesn't mean the product contains milk.
- You can freeze the brownies if you wrap them up well, for up to 3 months.
Are Oreos really vegan?
There has been some debate over whether Oreos are actually vegan, with the company themselves saying "Oreos have milk as cross-contact and therefore are not suitable for vegans". However, Oreos do not contain any animal derived products so they are suitable for vegans. If you have a serious dairy allergy though, you may need to avoid them. Of course, as with everything, it's up to you whether you eat them or not.
What are flax eggs?
Flax eggs are an egg substitute used in vegan and egg free baking. They are made from ground flaxseeds (also known as linseeds) and water. You can either ground the flaxseeds yourself using a pestle and mortar, or a blender, or you can buy ready ground flaxseeds. Ready ground ones are becoming more readily available now as lots of people add them to porridge and smoothies due to their health benefits. When water and ground flaxseeds are mixed together, after a little while, they become gelatinous. This creates a similar texture to an egg and it becomes a binding agent in your bakes, as well as adding necessary moisture.

I had no idea that Oreos were vegan Kat! Such a happy 'accident' for so many people eh 🙂 The brownie looks super yummy with all of that chocolatey heaven 🙂
Thank you! Indeed it is a happy turn of events!

Wow these look amazing!! Def pinning for later! Love a good vegan brownie making an espresso batch this morning!! Somehow chocolate bakes taste so much better vegan, maybe it's the dark chocolate yum!!
Had to read the bit about the may contain warning a couple of times as it sounded like 'may contain' makes it suitable for those with allergies... It's not what you meant I just hadn't had coffee!!
I've updated that sentence to make it clearer! Thanks for letting me know and I hope you try this recipe!
How many brownies can I make with this recipe?
It depends what size you cut them into! I do 12 big slices, but you could do smaller squares if you wanted to serve more people 🙂
Oh wow! These look amazing #FreeFromFridays
Thank you so much Chloe!

Love this Kat. Definitely worth trying a de-glutened version xx
I think they would easily convert to GF - let me know how it works out!
have baked these 3 weeks in a row every weekend, I do a mix of dark brownies and white brownies with choc chips in it.. my kiddos love it. I also use stevia instead of sugar. Its a family hit. Thank you
This looks so tasty. We are always looking for great content over at Cake Cetera.

OMG!! I just made them ! They are AMAZING!! Thank you!!
I'm having such a hard time converting everything into cups. I don't want to mess this up 🙁
Hi Iliana, this is the conversion:
250 g Plain flour - 2 cups + 1 tbsp
350 g Caster sugar - 1 + 3/4 cups
90 g Cocoa powder - 3/4 cups
1 tsp Baking powder
1 tsp Salt
1 tsp Vanilla extract
250 ml Almond milk - 1 cup
2 Flax eggs see instructions
250 ml Vegetable oil - 1 + 1/4 cup
154 g Oreos broken up - This is one packet, or one 'roll'
65 g 70% Dark chocolate - 1/2 cup dark choc chips
I'm assuming you are ok with the tsp/tbsp amounts?
Thanks for sharing these cup measures..I was looking for the same..
Hello, I was wondering if you could make them using oat milk rather than almond milk?
Hi, yes I don't see why not. I've never made them with oat milk but I think it would work fine, please let me know how it goes!
Can I replace almond milk with regular milk?
Yes of course, althought they would no longer be vegan if you use any milk from an animal
I have just recently come across your website and found this recipe - they are without doubt amazing! They have gone down a treat in our house! I just wanted to ask how long will they last and should they be stored in an airtight container? Thank you! Paula
Hi Paula, I'm so happy to hear this! Yes store them in an airtight container in a cool place and they will last 3-4 days.
Did anyone else have to bake extra long? My skewer is not coming out clean.
Hi Sharon, I've not had this feedback before, did you bake it in a smaller tin? If so, the mixture will need longer in the oven. As they're vegan, if they're a bit gooey in the middle it's not bad as there isn't any raw egg in them, and also brownies can be quite tasty when gooey (well I like them this way!)
Haven’t got flax seeds or linseed . What can I use instead
Hi Nigel, you can use chia seeds. I hope you enjoy the recipe!
Will definitely be making these again! They turned out incredible, really enjoyed the recipe- I used egg replacer (from holland&barett) as i didn’t have any flax and it still turned out amazing! 5 stars for sure!
Thank you so much Jasmine!
These were so delicious! Best brownie recipe I've ever used even before I went vegan. Awesome!
Thank you so much Kat!
I've been looking for a good vegan brownie recipe as I'm allergic to eggs and this turned out amazing! The oreos gave such a good crunch.
Thanks so much Kat!
One word- yummy! They are definitely the best vegan brownie recipe I have tried and I have a tried a few!
Absolutely loved these brownies! I couldn't find any flaxseed so used chia seeds but it still came out lovely😊
Hello there, I have just made your lovely Oreo brownies. Thank you for the recipe. Just a quick question please. I used the exact recipe and baked for 30 mins. They are delicious but I would prefer a less ‘cakey’ texture if possible. I was looking for a more gooey centre. Could you advise if this recipe could be adapted to help with this please. Thanks so much for your help 😊
Hi Mandy, I'm so glad you found them delicious! I haven't experimented with a fudgey vegan brownie recipe yet, or tried to adapt this recipe into one. I will put it on my reader request list for you 🙂
I just baked these, and the taste is fine, but the dry-to-wet ratio was completely off. The batter turned out like dough, so I had to add a lot more milk. I've checked and rechecked the recipe, and can't figure out where I've gone wrong.
Hi Ivy, firstly I'm sorry this happened as I know how frustrating it can be when things go wrong! Second, I'm not sure either but the most likely explanation would be not adding enough liquid. Did you add the vegetable oil? Other that than, I'm not sure what it could be. If you watch my video of making it you can see the batter consistency better too. I hope that helps!
Hey, do you have a non- vegan version of these? Or should I just use the normal choc brownie recipe and add Oreos?
Hi Georgina, yes you can make the non-vegan chocolate brownies and add Oreos 🙂
Sorry but these did NOT come out. I thought it was way too much oil so I cut it by 100 ML and still nothing after the allotted time. Trying to bake them at a higher temp for another 20 mins to see if all of my ingredients aren't wasted.
Hi Jessica, I'm sorry to hear this happened, however if you change ingredient amounts (or anything else) in a recipe then you are not going to get the same results.
