I made this cake for my sons’ 3rd birthday. I used a double layer 9×13 cake for the base. The dome of the clubhouse is made from cake that I backed in a rounded mixing bowl. The Mickey Mouse head and foot are made from rice krispy treats. I used a turret from a castle cake kit that I had to stand the Mickey mouse head up. I connected the foot to the cake with a marshmallow covered in icing. I bought the figurines at the Disney Store. The boarder is just piped on with a circle icing tip. All in all this cake was much easier to make than I expected. I am not an expert baker by any means, but I had fun making this cake and was please with the result. The kids at the party went crazy for the cake too!
