I attempted a sponge cupcake for T= Tiramisu. I had no idea how long to bake them since I was converting essentially a jelly roll sort of cake recipe into mini cupcakes. Apparently 14 minutes is too long. Probably 10-12 minutes is about right.
So I had 24 mini cupcakes unsuitable for solo consumption… While I made an espresso custard, I unwrapped them all and put them in a bowl. I dumped the custard on top, refrigerated and ended up with a trifle!
