Polystyrene cake dummy rectangular 30 x 20 cm, 5 cm high

This rectangular polystyrene cake dummy (30 x 20 cm, 5 cm high) looks just like a real cake once covered. It is also known as a styrofoam cake dummy, fake cake, dummy cake or display cake. Made from expanded polystyrene (EPS), it is light, stable and can be decorated like a real cake with fondant, marzipan or buttercream.

At 5 cm high this dummy is shallow: ideal as a base, for slim tiers, heart cakes or lettering. Two 5 cm dummies stacked give the classic tier height of 10 cm. The rectangular shape is ideal for book, logo and corporate cakes, sheet cake replicas and large displays in shop windows or at trade fairs.

More heights and shapes are available in Polystyrene cake dummies.

What is a polystyrene cake dummy used for?

• Display cakes for shop windows, trade fairs, photo shoots or wedding fairs
• Bigger wedding cakes: only some tiers are real – fewer ingredients and no waste
• Practice: covering with fondant, sharp edges, piping and sugar flowers without time pressure
• Cake decorating classes and workshops where the cake has to stay beautiful for a long time

Tips for covering

• Lightly sand the edges or round them with a smoother so the fondant does not tear.
• Moisten the dummy thinly with water, vegetable shortening or piping gel so the fondant sticks well.
• Never place a real tier directly on the polystyrene: always use cake boards and, for heavy tiers, cake dowels as well.
