Equipment

  • cupcake tin
  • Large mixing bowl
  • piping bag with #12 tips

Ingredients

  • 15.25 ounces chocolate cake box mix + all the ingredients indicated on the box to make cupcakes**
  • 1 stick butter approx. ½ cup, softened
  • 2 cups confectioners’ sugar
  • 1 tablespoon cocoa powder
  • 1 ½ tablespoons milk
  • ½ teaspoon red gel food coloring
  • 4 ounces black fondant

Instructions

  • Prepare cupcakes according to the mix’s directions. Bake and allow to cool completely before decorating.
    15.25 ounces chocolate cake box mix
  • In a large bowl, add butter, confectioners’ sugar, cocoa powder and milk. Use an electric mixer to beat until completely combined and smooth.
    1 stick butter, 2 cups confectioners’ sugar, 1 tablespoon cocoa powder, 1 ½ tablespoons milk
  • Add red food coloring to the buttercream mixture and beat until completely tinted.
    ½ teaspoon red gel food coloring
  • Scoop red buttercream into a piping bag with a round Wilton icing tip #12. Frost each cupcake.
  • Divide the black fondant into ¾ inch spheres — you will need 24 of them.
    4 ounces black fondant
  • Shape each sphere into a cylinder, about 1 inch long and ½ an inch wide.
  • Point one end of each fondant cylinder and then give it a curve upwards.
  • Place two black fondant shapes on each cupcake — these will act as the devil horns. You will want the pointy side sticking out of the cupcake.
  • Serve and enjoy!

Notes

Pro Tips

  • Most cake mix recipes make 24 cupcakes, but for this recipe, you only need 12. I recommend that you either split the cake mix and ingredients in half, or you can double the frosting and horns and make 24 of these spooky desserts. 
  • Be careful not to overmix the cake mix. Overmixing can lead to tough cupcakes. 
  • Make sure to allow the cupcakes to cool completely before adding the frosting. If they are too warm, the frosting will melt and run.
  •  If you want a more intense red color, you can always add more food coloring until you reach the desired shade. 
  •  If you have any leftover frosting, you can store it in an airtight container in the fridge for up to 2 weeks.
  • Insert a toothpick into the center of the cupcake to see if it’s done. If it comes out clean they are ready.
