Since the day Peter Parker was bitten by a radioactive spider in 1962, kids have been fans of that unassuming superhero, Spiderman. One part geeky nerd and the other part world-saving hero, Spiderman is a hero with which many children identify. If your child is a big fan of Spidey, surprise him with a spiderweb decorated cake for his next birthday party. This simple design takes minutes to make and fits perfectly with a Spiderman birthday party theme.
Place one cake layer in the middle of a serving tray or cake platter. Place about 1/2 cup of frosting on top of the cake layer. Smooth the frosting out to cover the entire cake layer. Center the second cake layer on top of the first.
Divide the remaining frosting into two bowls. Use food colouring to dye one bowl of frosting royal blue and the other bright red.
Frost the sides of the cake in a thick layer of royal blue frosting. Use a spatula to make the sides smooth.
Frost the top of the cake with the bright red frosting. Use a spatula to perfectly smooth the top surface frosting.
Use the gel frosting to draw a circle in the centre of the cake, keeping the line 1 inch from the middle where all the lines cross. This circle will be a total of 2 inches across. Make another circle 1 inch farther out, and a final circle another inch farther away from the centre. You now have three concentric circles on top of your cake in a sort of bull's-eye design.
Place a toothpick into the frosting at the centre of the cake. Draw a line in the frosting from the centre down toward the outside edge as if the cake were a clock and you were drawing toward the number 6. Place the toothpick back in the centre of the cake and draw a line up to the top of the cake toward the imaginary number 12.
Pull the toothpick through the frosting again from the centre toward the imaginary numbers 2, 4, 8 and 10. Each time you drag the toothpick through the frosting you will pull the gel lines down a little bit, creating a draped swag effect that looks like a spider web.
