This is my first Topsy Turvy cake. I did this for a 2 year old little girl's birthday. The person that ordered it loved it. I used the marshmallow fondant recipe that is on this site as well. It worked out great. I iced the cake in buttercream though and then used the fondant as my accent pieces. They were doing a pink, black and white poodle theme for the party. The cake flavors were chocolate, marble and strawberry.
