Step 4: Building Blocks
Find something to put your cakes on. I had a subway party tray that I saved and used it. Anything will work as long as you can turn the cake around as you decorate.
Take the frosting and use it as a mortar between the layers of cake. Stack the cakes like building blocks one on top of the other, then frost completely over the stack cakes.
Note: I started out with the two, when I realize it just wasn't tall enough I baked the other cake. You will notice, my top is larger than my bottom. This is due to the fact that I split the first mix in two. So, my advise to you is bake the cakes, and if one is smaller than on other clearly put the larger cake on the bottom.
