This 3D Maui cake was constructed using a 1/2 sheet cake carved and stacked iced with buttercream and covered with rolled fondant. I used gel colors mixed with almond extract to paint the colors onto the cake. I don't have an airbrush machine yet, so I use what I have! I crushed graham crackers for the beach, and buttercream icing for the ocean. The interenet research I performed on this cake has made me want to vacation there someday!
