A while ago I made chocolate bundt cakes to celebrate my 100th blog post and the sponge I made them with was so tasty that I wanted to try making other things with it. I’ve always loved whoopie pies, but sometimes shop-bought whoopie pies can be a bit too sickly because they have too much filling inside them and the quality of the buttercream icing often leaves a lot to be desired. The beauty of baking your own therefore, is that you can control the buttercream icing to baked sponge ratio to suit your own taste.
Although I used a proper whoopie pie tin it’s not completely necessary because you could just use a yorkshire pudding tin or something like it to bake your whoopie pies in. All you’re looking for is something that’ll control the spread of the sponge as it bakes and allow it to rise. In fact, if you don’t mind your whoopies looking a little odd you could even use a traditional fairycake shallow tin to bake them in.
I made my whoopie pies traditional chocolate ones, but you could omit the cocoa powder and make them with other flavours instead, such as vanilla (using 1 tsp vanilla extract), lemon (using the zest of 1 lemon) or bake them as a plain sponge but sandwich them with fruit jam as well as buttercream icing.
I can highly recommend making the chocolate whoopie pies though because they result in two rich, moist chocolate sponges that are bonded together with a lightly whipped decadent cocoa buttercream, creating the perfect cake for one. Stopping at only eating one is a different matter entirely though.
Preheat your oven to 180C/160C Fan/350F/Gas mark 4.
Lay out your whoopie pie tins and give them a light greasing before dusting them with flour.
Measure all of the wet ingredients into a mixing bowl.
Measure all of the dry ingredients into another bowl and give it a stir.
Add the dry ingredients into the wet ingredients and mix well.
Pour equal amounts of the cake mix into the whoopie pie tins.
Bake in the oven for around 10-12 mins. (They’re cooked if a skewer pushed into the middle of a couple of the cakes comes out entirely clean.)
Leave to cool on a cooling rack before taking the whoopie pies out of the tin.
Place your buttercream ingredients in a large mixing bowl and whisk together.
Once cool, sandwich the whoopie pies with the buttercream icing.
