Prepare two 8″ cake pans by coating with a small amount of butter and flour, and placing parchment paper in the bottom.
Prepare one batch of batter and color it red (I used Americolor super red gel). Divide the batter equally and pour into the two prepared pans.
Bake for 22 - 30 minutes at 350 degrees
While the red cakes are baking, prepare another batch of batter. Divide the batter into two bowls and color one of the bowls of batter blue (I used Americolor royal blue). Leave the remaining bowl of batter uncolored.
When your red cakes have baked and cooled, remove from pans. Wash and then prepare pans for the white and blue batter. Bake.
Slice the two red cake in half (horizontally), so you’ll have a total of 4 red layers. Set aside one layer, this will not be used for the cake. Cut a 4″ circle out of one of the layers. So you want to have two 8″ round layers and one 4″ round layer.
Cut the white cake in half as well. Then use a 4″ cookie cutter to cut a circle out of one of the halves.
Use a 4″ cookie cutter again (or make a 4″ circle of cardboard and use that as your template) to cut out the center of your blue cake.
Assemble cake with a thin layer of frosting between each layer of cake, starting on the bottom with red cake, then white, then red, then blue. Add some frosting along the inside “ring” of the blue cake to hold in the next two layer which will fit inside the opening. Fill the hole in the blue cake with a 4″ round layer of with cake, some frosting, then the 4″ round of red.
