Chocolate sponge cupcake

After baking the Brownie, my mum told me might not be enough for my cousins. So I bake another batch of simple chocolate cupcakes. The look is not so fantastic, but the cup cake is so soft and fluffy!

I use the receipe of sponge cake, but added 20g of Hersley cocoa powder. Haha... was tire after preparing dinner and the brownie!
