What fake birthday cakes lack in fat and calories, they make up for in personality and longevity. Serve a fake cake to an unsuspecting person on his birthday, complete with fake candles. Or, give your child a fake cake along with a collection of felt decorations, including icing layers and letters, to provide her with hours of entertainment. You can customise this cake by changing the colour of the felt, such as red for red velvet cake or yellow for lemon cake.
Place an 20 by 10 cm (8 by 4 inch) round foam cake on 1 metre (1 yard) of felt according to the "flavor" of birthday cake you want to make, such as white for vanilla or brown for chocolate.
Squirt a liberal amount of hot glue using a low-heat, hot-glue gun over the top of the foam cake. Pull the felt up around the foam and gather the felt at the middle of the top of the foam; pull the felt taut as you do this. Press the felt against the hot glue.
Cut off the excess felt from the centre of the foam. Add hot glue to the cut-off portion of the felt and press it against the foam. Flip the covered round over.
Choose a colour of felt that you want to use for the icing of the cake. Cut out a 2.5 by 63.75 cm (1 by 25 1/2 inch) strip of the desired colour of felt using a pair of scalloped or pinking scissors. Press the felt icing strip around the top of the side of the cake with the straight edge facing up.
Draw the words "Happy Birthday" in 5 cm (2 inch) tall block or bubble letters on a sheet of felt in any colour. Trim the letters out and press them onto the top of the cake in the appropriate order.
Cut out 12 circles that are 1.2 cm to 5 cm (1/2 inch to 2 inch) circles from assorted colours of felt. Apply the dots randomly over the top and sides of the cake.
Cut a 10 by 10 cm (4 by 4 inch) piece of felt; choose the colour according to the colour of candles you want for the cake. Place a toothpick along one side of the felt and roll the felt around the toothpick into a tight tube. Apply hot glue to the open edge and press against the tube.
Cut a 2.5 cm (1 inch) long teardrop from yellow felt and hot-glue the round end to one end of the felt tube so that the teardrop stands up for the flame. Repeat this process to make as many birthday candles as you need for your cake. Attach the candles to the top of the cake using hot glue.
Add more glue around the base of the candles for support, as needed.
