    Making a fake cake might sound like a mean joke, but these cakes have a few important purposes. A fake cake can serve as a display cake to show off a baker's decorating skills. Display cakes are also sometimes used at weddings or other large gatherings to save money. An elaborately decorated dummy cake is set up to impress guests and then removed just before slices of a simple sheet cake are served. Whether you want to make fake cakes for gag gifts or a special occasion, the process is similar to decorating a real cake.

    • Cake dummy
    • Latex caulk
    • Spackle paste

    Purchase a foam cake dummy in the shape and size of your desired fake cake. You will need several dummies in different sizes to make a multiple tier cake.

    Stack the cake dummies together if you are making tiers and use a small bit of latex caulk between each tier to prevent the cake from toppling over.

    Mix together 2 cups of spackle paste and 1 cup plaster of Paris in a disposable plastic container.

    Stir 1 tbsp. of water at a time into the mixture until it resembles frosting.

    Frost the cake dummy with your fake frosting in the same way you would frost a real cake. Let the frosting dry on the cake dummy overnight.

    Paint the frosted cake with latex paint in the color of your choice.

    Pipe a border or message onto the cake with latex caulk when the paint is dry.

    • Instead of using the spackle mixture as frosting, you can use a non-edible frosting product specifically designed for use on dummy cakes.
    • Another option is to cover the cake with rolled fondant. Wipe the cake dummy with a damp paper towel to moisten the surface and cover it with fondant rolled approximately 1/8-inch thick. Smooth the fondant and decorate the cake with fondant or buttercream decorations. Fake cakes covered in fondant or buttercream icing will eventually begin to mold so do not use this method if you wish to create a long-lasting cake.
