So here we go... this is what my afternoon looked like.
Dye them with Gel food colouring. It turns out really good.
Bake them off in batches (since I only had 2 pans this took a little longer.)
Stack them all up layered with vanilla icing, cover and voila! Now this is with 2 cans of Betty Crocker, and clearly it wasn't enough. So keep that in mind. Plus it was so sweet, so if you are using the store stuff, I say maybe don't do 6 layers.
OHHH you want to see what it looked like inside??? Ok so this is a rough draft, but here you go:
I'll post the final product some time in the next couple of weeks.
