Styrofoam cakes are all the rage in the wedding industry. The faux cakes can be as detailed and elaborately decorated as you want while still remaining budget-friendly. The cakes can be used as display pieces at a wedding reception and slices of simple sheet cake can be served to the guests. You can also have round Styrofoam cakes as tiered decorations that sit on a real wedding cake or rectangular Styrofoam cakes decorated to look like fancy sheet cakes.

Step 1

Buy Styrofoam disks that are 2 inches thick each. Heat up the glue gun and insert a glue stick. Place one large disk flat on the table and glue the second large disk on top. Make sure the disks line up exactly and create a smooth silhouette.

Step 2

Place a medium Styrofoam disk on top of the large disks. Move the medium disk around until it is perfectly centered. Note the position and use the glue gun to glue the medium disk on the large disks. Glue the second medium disk on top of the first and line up the edges exactly. Repeat the process using the small disks.

Step 3

Measure out the amount of thick and fancy ribbon you’ll need to wrap around the large discs. Cut the ribbon and glue one end straight to the side of the large disks. Wrap the ribbon around the disks evenly so it looks like the sides of the bottom tier are decorated. Fold and glue the loose ribbon end in place so the ribbon appears seamless around the disks. Repeat the process with the medium and small disks.

Step 4

Arrange small flowers and delicate filler to create a rounded bouquet on the top of the cake. Push the bouquet into the small disks so it looks like the top of a wedding cake. Cut and arrange individual flowers and filling to lightly decorate the top edges of the medium and large disks like the tiers of a cake.

Step 5

Slide the Styrofoam cake on a fancy platter and place on a table to display.


  • If you’re looking for an extremely fancy cake, you can buy fancy cake forms created from Styrofoam. These forms are used to practice icing techniques and look perfectly realistic. However, buying one of these forms costs much more than making a simple form yourself.


  • Use a low-temperature glue gun when securing decorations to Styrofoam. High-temperature glue guns can get so warm that the glue ends up melting the Styrofoam and ruining your cake.
