I don't do many how-to posts. Would you like to see some more?
I thought I'd share this "hack" so you don't feel as if you have to buy a heart-shaped cake pan just to make a heart-shaped cake. This is really a piece of cake...or two cakes. Hehe. Here you go...
For each layer, bake an 8" round and an 8" square. You can use 9" also. Just make sure that the diameter of your circle matches the side of your square. Let cakes cool. It's actually easiest to work with cake layers that have been frozen.
Slice the round cake in half.
Arrange pieces to form a heart.
Adhere the round halves to the square with frosting. Shave the cake down so that the surface is flat.
Eccolà! A heart-shaped cake without a heart-shaped pan. It's almost magic!
