8-inch circular cake pan
Ball shaped cake pan
Large serving dish
Edible silver, gold or copper dust
Piping bag and piping tip (optional)
Toilet cakes seem odd to some, but bakers occasionally receive requests for the specially-shaped treats. The cakes are typically used for plumbers or to celebrate a child's achievements in potty training. Depending on your personal tastes, you can experiment with food coloring and piping to make the basic toilet as traditional or repulsive as you like.
Pour cake batter into all five of the cake pans and bake the cakes according to the directions in your specific cake recipe.
Allow the cakes to cool thoroughly.
Cut the square cakes in half to make six 4-by-8-inch cakes.
Cut a hole in the middle of one of the round cakes. The remaining donut shape will be the toilet seat. Cut a gap in the donuts to make a horseshoe shape.
Coat all of the cakes with buttercream frosting.
Spread a small amount of frosting on the bottom of the serving dish to create a glue for the cakes.
Stack the 4-by-8-inch cakes on one end of the dish to make the toilet tank. Attach each layer to the previous layer using wood dowels and frosting.
Roll out enough fondant to cover the toilet tank. Cover the tank with the fondant and trim away excess with a sharp knife.
Roll out enough fondant to cover the ball-shaped cake, which will be the toilet bowl. Place the bowl round-side-up and cover it with fondant. Cut off the excess with a sharp knife.
Roll out enough fondant to cover the toilet seat. Wrap the fondant around the toilet seat and trim away excess with a sharp knife.
Place the toilet bowl in front of the toilet tank, flat-side-up, and place the toilet seat on top of the toilet bowl.
Mix buttercream frosting with a few drops of blue food coloring to make water-colored frosting. Spread the blue frosting on the flat surface of the toilet bowl, but not on the toilet seat.
Shape fondant into a wedge-shape to make the flusher. Attach the flusher to the toilet tank, using a wooden dowel. Paint metallic dust onto the flusher, using a paintbrush.
Color additional buttercream frosting as desired and write a message on the toilet tank, using the piping bag.
