Blend sugar and margarine until fluffy. Slowly add eggs. Then slowly add flour.
Seperate batter into 4 parts. Color 2 parts red, one part blue and leave the last part as is (white/plain). Pour batter into cake pans and bake for 30min at 350°F/180°C.
After cooling cut cakes horizontally. Red cake = 4 layers, white cake = 2 layers. Do not cut blue cake horizontally.
Take a bisquit cutter or bowl about half the size of cake pan. With that cut out the centers of the blue cake and of 1 layer of red and 1 layer of white.
Layer the cake with frosting inbetween. Start with red, then white, then red again. Now use the blue cake ring. Finally fill the center of the blue cake ring with the red and the white center pieces. Cover cake with frosting.
Decorate the cake with red, white and blue or your favorite ID4 decoration.
