Cake paste???? Well cake paste is what you make when doing cake pops..cake leftovers and butter cream. When making this cake paste make sure it is not to wet or too dry...then you can use it like clay and shape it for things like tails, heads, legs..and you let it dry a bit and cover with icing and or fondant. I love using it for shaping legs and tails etc.. It sticks well to other cake parts or for building up parts of your cake...
