This Great Cake Contest entry was submitted by turtlebugmama from Norfolk, Virginia: Cake for a 3 year old's party with Mickey as the theme. I went with the clubhouse as the theme of the cake to try something a little different.
Prepare cake mixes according to boxes (I did half chocolate and half vanilla) in a sheet cake pan, saving about 3-4 cups of cake batter. Bake saved batter into Pyrex bowl or dome pan. Prepare Rice Krispie treats according to box.
Decorate sheet cake with grass green frosting. Make a small "sand" area in lower left corner yellow frosting- top with yellow sprinkles. Decorate dome cake with red frosting and little windows. Set dome cake on back center of the cake.
Mold Rice Krispie treats into 1 large ball and 2 smaller balls for Mickey head. Mold a small shoe shape. Wrap PVC pipe sections in black electrical tape and then saran wrap. Wrap a rolled piece of aluminum foil with pipe cleaners for the slide. Adhere top to the dome section and bottom rests in sand area.
Insert 6" PVC pipe into upper left corner of cake. Place glove on top (can stuff with tissues if needed). Insert 8" PVC into dome cake top. Insert 3" PVC pipe out right side of dome. Spray molded Krispie shoe with yellow cake spray- attach to 3" PVC section. Spray molded Krispie balls with black color spray. Attach smaller balls to large ball with BBQ skewers.
Stick several skewers into the bottom of the large ball and insert 'head' section into 8" PVC pipe. Add a frosting window, door knob and welcome mat to shoe section and set figurines on cake. Tip: Keep Krispie treat molded sections in the freezer until serving to hold their shape."
