You have to use the debbie brown recipe - it's a bit like a madeira (heavier) sponge, leave it a day and then it is perfect for carving without crumbling. I've made a Pingu cake with this (and the help of my younger sister) and it was AMAZING! Was so very proud of myself.
Ds is skylander mad and has seen a cake ob youtube he wants me to make. I'm fine at decorating but useless at baking often cheat and decorate a ready made cake the cake needs to be cut into a body and arms/legs and sort of stuck together. The problem is all my recipes produce light fluffy crumbly cakes.
I will try to post the link later, not sure how on my phone. Anyone have a good recipe or a suggestion for cheating a good supermarket cake?
