The cake was a recipe from Cake Doctor. It was a Yellow Sour Cream Cake with Vanilla Buttercream frosting. The fondant was Elite. It contains white chocolate and is really good. The print at home graphics came from B Squared Design.
After I made the cake batter, I separated it into thirds and used gel color to make the red, blue and yellow. Gel colors are preferred because it takes very little to color a cake, as opposed to the old fashioned liquid kind. I layered the colored batter on top of one another in concentric circles. I tried hard not to move the pan too much. Rather than evening out the batter with an offset spatula, I gently taped it on the counter and placed it in the oven. The food color did not change the cooking time.
This is what the cake looked like when it was cut. I almost cut the cake into four layers but I didn't want to disrupt the natural swirl that was created as the cake baked. It was a hot day, so I opted for just a bit of buttercream between the layers. Especially because I made and frosted the cake just hours before the party and there was little time to refrigerate. It all made for a super light and moist cake.
