====== Quick-mix Sponge Cake ====== * 150g self-raising flour * 1 tsp baking powder * 150g soft unsalted butter * 150g caster sugar * 3 eggs For chocolate cake, substitute 1 heaped tablespoon of the flour with one heaped tablespoon of cocoa. Preheat oven to 160 degrees celsius. Grease a 20cm / 8" round tin. Sift together the flour and the baking powder. Add the butter, sugar and eggs. Beat with a wooden spoon until the mixture becomes even and pale. Spoon into the well-greased tin and bake for 30 minutes or until a skewer inserted into the middle of the cake comes out clean. Immediately turn out on to a wire rack and leave to cool. Cut in half and spread whipped double cream on one side and jam on the other, put back together - voila. This will make 12 cup cakes @ 30g each.
