How to Make this
Baby Sheet Cake

Bake a sheet cake the size that you need. Divide the top of the cake into twelve squares using an icing filled bag and round tip size #5.

Use your choice of colored icing, just make sure you don't use the same color next to each other.

Ice the center squares first smoothing the icing on each square with a small icing spatula.

With white icing and star tip #18, do a shell border on lines between the blocks doing the sides also. Finally, do the shell border around the bottom and the top of the cake as shown in the above picture.
