    My Cotton Candy Cake is a fun birthday recipe, flavored with soda to taste just like cotton candy. Its bright blue color and delicious flavor make it perfect for parties. Imagine biting into a cloud of pure sweetness, a swirl of pastel perfection that melts in your mouth. This white cake recipe tastes like cotton candy. With pink and blue buttercream frosting, sprinkles, and maybe a cloud of cotton candy on top. This fabulous dessert also comes with a buttercream recipe, and the frosting also tastes like colorful cotton candy.

    Cake Directions

    1
    |
    Preheat oven to 350F.
    2
    |
    Grease a 9″ x 11″ casserole dish and set aside.
    3
    |
    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.)
    4
    |
    Bake for 25-30 minutes, until an inserted toothpick comes out clean.
    5
    |
    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

    1
    |
    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.
    2
    |
    Use an offset spatula to spread the frosting on the cooled cake.
    3
    |
    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.
