Method
Preparation
- Preheat oven to 350°F. Grease a 9×11 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.
- Bake for 25-30 minutes, until an inserted toothpick comes out clean. Allow the cake to cool completely before frosting.
- Meanwhile, heat 1 cup of cotton candy soda in a saucepan until boiling, then simmer until reduced to 1/4 (2 oz). Allow to cool completely.
- For frosting, beat together butter and powdered icing sugar for 2 minutes, add reduced soda, and milk as needed for texture. Adjust color with blue food dye, if desired.
- Spread frosting on cooled cake using short strokes for texture, and garnish with sprinkles.
Notes
Keep the cake in an airtight container at room temperature for up to 2 days. If your kitchen is warm or humid, refrigerate for up to 4 days; bring to room temperature before serving. Freeze individual slices wrapped tightly in plastic and foil for up to 1 month; thaw in the fridge and sit at room temp for 30-60 minutes before serving. Use chilled soda for cake batter in hot conditions.
