Gently fold in the melted butter. Sift the flour, cocoa and baking powder over the surface and fold in using a large metal spoon, trying not to knock out too much air. Divide the mixture between the cases, then bake for 15-20 mins until well risen and the sponge springs back when gently pressed. Leave to cool in the tins for 5 mins, then lift out onto a rack.
