Equipment

Ingredients
 

Cake Ingredients:

  • 12 ounces Cotton Candy Soda, can use cream soda, if needed
  • 1 box White Cake Mix, 15 ounces
  • Light Blue Food Dye, optional

Frosting Ingredients:

  • 1 cup Cotton Candy Soda, or use 1 teaspoon Cotton Candy flavor extract
  • ½ cup Butter, softened
  • 4 cups Powdered Icing Sugar
  • 1-2 tablespoons Milk
  • Light Blue Food Dye, optional
  • Pastel Sprinkles, as desired

Instructions
 

Cake Directions:

  • Preheat oven to 350F.
  • Grease a 9" x 11" casserole dish and set aside.
  • In a large bowl, beat together the white cake mix and cotton candy soda for 2 minutes. Adjust the color with light blue food dye, if desired. (If using, make the cake batter a deeper blue than you want the finished cake to be as it will lighten with baking.)
  • Bake for 25-30 minutes, until an inserted toothpick comes out clean.
  • Allow the cake to cool completely before frosting.
  • Meanwhile, place 1 cup of cotton candy soda in a saucepan and heat until boiling over medium-high heat. Reduce to medium-low and simmer until reduce to 1/4 (2 oz of soda should remain). Allow to cool completely.

Frosting Instructions

  • In a large bowl, beat together the butter and powdered icing sugar for 2 minutes, then add the reduced cotton candy soda. Beat to incorporate, then add the milk as needed to achieve a spreadable texture. Adjust the color with blue food dye, if desired.
  • Use an offset spatula to spread the frosting on the cooled cake.
  • To achieve the fun texture shown in the pictures, use short strokes to spread the frosting, then go back over the frosted cake and rough it up a bit.
  • Garnish the cake with sprinkles, as desired.

Christina's Notes

    • Decorations Get creative with your decorations! You can place sprinkles, edible pearls, or even small cotton candy-themed toys onto the cake.
    • Parchment Paper: Use parchment paper so the cake comes out cleanly.
    • Glitter: Add some sparkle with edible glitter or sprinkles around the cake to make the cake look more magical.
    • Layer Cake: Make a tiered cake using 8-inch cake pans. Make each layer of cake a different color, then top with fluffy cotton candy.
    • Egg Whites: Try using egg whites in the icing for this vanilla cake recipe.
