In a stand mixer, mix 2 cups of heavy cream, 7 ounces of condensed milk, and the pink cotton candy until soft peaks form. Transfer it to a bowl and set it aside.
Using the same bowl, mix the remaining 2 cups of heavy cream, 7 ounces of condensed milk, and the blue cotton candy until soft peaks form.
In a loaf pan, layer the ice cream by alternating between the pink and blue mixtures. Sprinkle with your favorite toppings like sprinkles and chocolate chips. Freeze it overnight.
Your homemade ice cream can be stored in the freezer for 1-2 weeks. Enjoy the deliciousness!
