To make the frosting, use a mixer to beat the salted butter until it becomes light in color, about 2 to 3 minutes. Beat in the whole milk, lemon juice, cotton candy extract and salt until combined.
16 tablespoons salted butter, 2 to 3 tablespoons whole milk, 1 teaspoon lemon juice, ½ teaspoon cotton candy extract, ½ teaspoon salt
On low speed, add in the powdered sugar, gradually increase the speed to high and beat for 5 minutes or until the frosting is light and fluffy.
5 cups powdered sugar
Divide the frosting into two separate bowls and add the blue food coloring to one bowl and the pink to the other. Stir until the color is completely combined and the desired color is reached, adding more coloring as needed.
Blue food coloring, Red or Pink food coloring
To get a multi-colored marbling effect for your frosting, place both frosting colors in a piping back. Alternate placing large spoonfuls at a time of each color until the piping bag is filled.
Use a piping bag and star tip to frost the cupcakes with the pink and blue frosting.
Top the cupcake by adding sprinkles and some pink and blue cotton candy, optional. Serve and enjoy!
