I was given a Batman cookie cutter for my birthday, so I thought, what's the most original Batman recipe I can make?? (Plus I'd been wanting to make a surprise cake for AGES!)
Preheat the oven to 180C and line a 35 x 25cm brownie tray with greaseproof paper. Melt the butter, then add to the 6oz Caster Sugar, 3 Eggs, 4.5oz Self-Raising Flour and 1.5oz Cocoa Powder. Mix until fully incorporated, then spread evenly into the brownie tin and bake for 10-12 minutes. When cooked, leave aside to cool.
Melt the butter, then beat in the sugar until light and fluffy. Add the eggs, flour and vanilla essence and beat until all the ingredients are fully incorporated. Spoon a little under half of the mixture into the loaf tin, place in the oven and bake for around 10-15 minutes.
While the bottom half of the loaf cake is in the oven, take the cutter of your choice (in this case, Batman!) and press out 12 shapes from the chocolate mix. You want these shapes to be as accurate as possible to the cutter, so make sure to be careful when removing the sponge from the cutter!
Remove the bottom half of the sponge mix from the oven. The mixture should be spongy, but should not feel fully cooked.In a line along the centre of the loaf tin (along the tin rather than across the tin, so that each slice will have a shape in it), place the shapes onto the partly-cooked sponge mix. Press the shapes tightly together and make sure that they are lined up as closely as possible.Then, add the remaining half of the sponge mixture around the sides and top of the Batman centre, and put back in the oven for 20-30 minutes.
Once the cake is cooked, leave to cool then decorate with butter icing or ganache. (I used yellow buttercream and piped 'Na Na Na Na, Na Na Na Na...' on the top because I'm hilarious)
