After stumbling across and ordering a whoopie pie tin on Amazon (whilst looking for hair curlers…yeah, I don’t know how that happened either), I’ve been dying to try this recipe out. I would stress the importance of not overfilling the holes if you do use a tin; if you do, as I did, you won’t end up with these:
You’ll have yourself a few of these brutes:
Aren’t they pretty?
For the sponge:
120g unsalted butter, softened
200g soft dark brown sugar
1 large egg
120ml buttermilk (if you don’t have buttermilk, just add 1 tsp lemon juice to this quantity of milk and leave to stand for five minutes before use)
1 tsp vanilla essence
340g plain flour
2 tbsp cocoa powder
1/2 tsp bicarbonate of soda
30ml red food colouring (do not, I repeat, DO NOT use ‘natural’ food colouring as it will not be strong enough to produce the red that you want for red velvet)
For the filling:
170g cream cheese
90g unsalted butter
1 tsp vanilla essence
120g icing sugar
Preheat the oven to 170°C and line two baking sheets with greaseproof paper.
Using a handheld electric whisk, cream the butter and sugar together until light and fluffy in texture. Add the egg whilst mixing on a low speed and whisk until fully incorporated.
Mix the buttermilk and vanilla essence together by hand, then pour into the creamed mixture whilst mixing on a low speed. Sift the flour, cocoa powder, bicarbonate of soda and salt together and add to the batter in two batches, mixing thoroughly after each addition. Add the red food colouring and increase the speed before giving the batter a final mix to ensure an even red colour throughout. Refrigerate the batter for 20-30 minutes to allow it to cool and set slightly.
Once cooled, spoon or pipe the batter onto the prepared trays (you’ll probably get eight to ten mounds per tray, each being about 3-5cm across and 2-3cm apart). Bake for 10-13 minutes or until springy to touch, then allow to cool completely.
While the sponges are baking, make the filling. In a bowl, beat the cream cheese, butter and vanilla on a low speed until fully combined. Add the powdered sugar bit by bit until all is incorporated. Beat for 1 minute. Be careful not to overbeat as the cream cheese can quickly cause the mixture to become runny, which is not what we want. Place the filling in the fridge until you’re ready to use it.
Once the cakes are completely cooled, spread about a tablespoon of filling onto the flat side of one of the sponges, then stick a sponge of similar size on top of it. Repeat with the remaining sponges and filling.
