So for this all you need is a baked cake and ganache or frosting!
First you want to crumble the cake(any flavour) when that's done slowly mix in your frosting until when you squeeze it, it holds its shape.
This is a great way to use leftover cake and cake scraps
Plus you can decorate them anyway you want!
