How to make fake cakes

Making a fake cake may 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 as stage props or 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 tray cake are served. Whether you want to make fake cakes for joke gifts or a special occasion, the process is similar to decorating a real cake.

  1. 1

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

  2. 2

    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.

  3. 3

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

  4. 4

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

  5. 5

    Ice the cake dummy with your fake icing mix in the same way you would ice a real cake. Let the icing dry on the cake dummy overnight.

  6. 6

    Paint the iceded cake with latex paint in the colour of your choice.

  7. 7

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

Tips and warnings

  • Instead of using wall filler as icing, you can 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 75 mm 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 mould so do not use this method if you wish to create a long-lasting cake.
