Side view of cake. Wheels were oreos and the icing is buttercream. I made a cake in a 9 X 13 X 2 pan and cut it to size. I had a small oval serving dish and I made the turret in that and topped it all off with a brownie cupcake. I frosted the cake first in the brown frosting, smoothed it using the viva method, added green icing in a mock camoflauge pattern and also used the viva method at the end. I had fun making this cake!!
