I am completely obsessed with Reese's Peanut Butter Cups, especially the mini ones. The combination of chocolate and peanut butter is so addictive for me. My sister bought me giant PB cups for Christmas and she recently sent me a photo of Reese's spread. I knew that I had to get some of the spread and that these Ultimate Reese's Peanut Butter Cupcakes had to happen! The sponge is flavoured with peanut butter and two Reese's Mini PB Cups are inside each cupcake. The buttercream is made from Reese's spread, and then there are more Mini PB Cups on top. These Reese's Peanut Butter Cupcakes are the ultimate combination of chocolate and peanut butter!

How to make Ultimate Reese's Peanut Butter Cupcakes
To make the sponge mix together butter and caster sugar. Then add eggs and peanut butter and whisk them in.
Next mix in self raising flour. Divide the mixture into a lined cupcake tin. Into each cupcake place two mini Reese's Peanut Butter Cups that have been in the freezer for an hour on top of the batter.
Bake them and leave to cool. Make the buttercream by mixing butter, icing sugar, Reese's Spread and milk together until smooth. Put the buttercream in a piping bag with a Jem 1E nozzle and pipe it onto the cupcakes. To decorate, cut two Reese's Mini Peanut Butter Cups in half and place them on top.
How long do the cupcakes last for and can they be frozen?
The cupcakes will last for 2-3 days in an airtight container in a cool place. You can freeze both the cupcakes and the buttercream. To freeze them separately, wrap the cupcakes well in cling film or put them in an airtight container. The buttercream can be frozen in a sealed tub. To freeze them decorated, freeze the cupcakes on a plate until frozen solid, then carefully wrap in cling film. Remove the clingfilm when you take the cupcakes out of the freezer to defrost, as if they defrost with it still on it could damage the buttercream.
Can you make the cupcakes with plain/all purpose flour?
Self raising flour, which is very commonly used in the UK where I am based, already contains a raising agent and a little salt too. Therefore if you want to swap it for plain or all purpose flour, you will need to add some additional baking powder and also a little salt if you like. Some people like to add salt to cake recipes and some don't, so I'll leave that up to you as it won't affect the bake. The general advice is to add 2 teaspoons baking powder (a measuring teaspoon, not the kind you stir your coffee with) per every 200g plain or all purpose flour. So for this recipe you'd need to add 1 + ¾ teaspoons baking powder. Please note, I have not tested this recipe using plain or all purpose flour.
Can the cupcakes be made gluten or dairy free?
Yes! For gluten free you can replace the self raising flour with a gluten free self raising flour blend. If you only have a gluten free plain flour blend, you will need to add baking powder. The general advice is to add 2 tsp baking powder per 200g flour, so for this recipe you'd need to add 1 + ¾ teaspoons baking powder. You may also like to add ¼ tsp Xanthan Gum for better texture. For a dairy free version, use a dairy free baking spread for the cupcakes and a dairy free butter and dairy free milk for the buttercream. You will also need to use a dairy free alternative to Reese's peanut butter cups.
Tips for making the Ultimate Reese's Peanut Butter Cupcakes:
- You don't have to use mini peanut butter cups, you can use the regular size ones too. Only use one peanut butter cup inside the sponge if you are using larger ones.
- If you can't get hold of Reese's spread, check the recipe notes for a delicious chocolate and peanut butter buttercream you can use instead. I get the spread from Sainsbury's in the UK.

- 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.
