Prep Time30 mins
Total Time30 mins
Servings: 1 Cake


  • 13 x9 Cake Could be box mix or your fave recipe!

  • For the Buttercream Frosting:
  • 1 cup softened butter
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 to 2 tablespoons milk
  • Food coloring brown, orange, yellow, red

  • For the Royal Icing Pepperoni:
  • 3 tablespoons meringue powder
  • 4 cups powdered sugar
  • 5 tablespoons warm water
  • Red food coloring


  • For the frosting: In the bowl of a stand mixer fitted with the paddle attachment, cream the butter till smooth.
  • Add in the powdered sugar, vanilla, and milk. Mix on low till combined.
  • Turn the mixer up to medium and continue to whip the frosting for a minute or so.
  • Divide into bowls and color with food colorings. You'll need yellow for the "cheese", red for the "sauce" and tan for the "crust".
  • For the pepperoni: Combine all ingredients in the bowl of a stand mixer and mix on medium high for 7 to 10 minutes. Add red food coloring.
  • Place the icing into a piping bag fitted with a medium round tip.
  • On a large sheet of parchment paper, pipe a bunch of 1 inch red circle shapes. Let set till hardened and gently peel off from the parchment paper.
  • To assemble: Using a long sharp knife, slice a 13 x 9 inch cake of your choice into a large triangle.
  • With a pale tan colored buttercream, frost the entire cake. First do a very thin crumb coat. Chill in the fridge for about 30 minutes. Then do another coat of buttercream.
  • Spread red colored buttercream over the top and slightly over the sides of the cake for the tomato sauce, leaving the “crust” the dough color. Chill.
  • Finish off with your yellow buttercream for the cheese, leaving some of the red “sauce” showing around the edges.
  • You can also add a little darker brown buttercream to the “crust” to add some more dimension.
  • Top with some of the royal icing pepperoni. You can slice some of the pepperoni in half using a sharp knife to place along the edges of the pizza slice.
