ASSEMBLY OF CAKE: Place 1 red cake layer on cake stand or serving platter; spread 1/3 cup frosting on top. Top with 1 white cake layer; spread 1/3 cup frosting on top. Top with second red cake layer; spread 1/3 cup frosting on top. Gently top with blue layer. Carefully spread thin layer of frosting on cut edge inside of blue cake layer.
