P.S. Sorry the picture quality isn't the best, but you get the idea!
Step 1: Bake two 9-inch cakes of two different flavors/colors (you will have 4 9-inch cakes total).
Step 2: Cut a 7-inch circle out of a piece of parchment paper. Also cut a 5-inch circle out of parchment paper.
Step 3: Place the larger circle on each cake and cut around with a knife. Place the smaller circle inside the smaller cake cut-out and cut around with a knife. Separate each piece.
Step 4: Put each cake round so they are alternating colors (in this case, two of the cakes were vanilla, chocolate, vanilla and the other two were chocolate, vanilla, chocolate).
Step 5: Stack the cakes so the outer layer alternates in color/flavor (chocolate, vanilla, chocolate, vanilla). Make sure to spread some icing in between each layer!
Please note I only used three out of the four layers since my travel container wouldn't hold all four layers).Step 6: Cut and enjoy! This obviously isn't the best picture, but you get the idea! Everyone (especially the kids) thought it was really cool!
