4/7/10 inch white cakes torted and iced with buttercream and covered in fondant. I don't have the traditional impression mat for the bricks, so I used a brick veneer for doll houses I bought on the cheap at Hobby Lobby- it does the trick. The turrets are gum paste. I keep all my paper towel rolls and craft paper rolls just incase! The tops are molded around ice cream cones, I wrapped the cone with wax paper to prevent the 'cone' impression and once it was dry I removed the wax paper and slipped it back onto the cone with some white chocolate. Each turret is secured with white chocolate 'glue' to the cake.
