Instructions

Preheat oven to 350 degrees. Spray or line a standard muffin tin.

Add cake mix to a large mixing bowl. Using a hand or stand mixer, mix in your water, oil, and eggs on medium until well incorporated. Mix in the ricotta cheese.

Evenly separate the batter into 6 containers and color each with the 6 food colors until desired color of each is achieved.

Add a small spoonful of each color of the batter into the muffin tin until each is about 2/3 full. Bake for 18-20 minutes, or until a toothpick comes out clean. Allow to cool completely before frosting.

Directions for Frosting

In a large mixing bowl or stand mixer, cream the butter, and beat until light and fluffy. Add in the vanilla extract.

Slowly mix in the powdered sugar, 1 cup at a time, while adding a bit of the half and half or milk in between each cup. Continue to mix for 1 minute or until creamy. Add in your marshmallow flavoring.

Prepare piping bag and fill bag with frosting. Frost your cupcakes and top each cupcake with the rainbow sprinkles

Tips & Tricks (5)

Color Intensity Magic 🎨
Use gel food coloring instead of liquid for vibrant, concentrated colors that won't thin out your batter or compromise cupcake texture.
Ricotta Moisture Secret 💧
Drain excess liquid from ricotta cheese before adding to cake mix to prevent soggy cupcakes and maintain perfect texture.
Layering Rainbow Technique 🌈
Use a small ice cream scoop or piping bag to create precise, even color layers in each cupcake for a stunning rainbow effect.
Marshmallow Frosting Perfection 🍬
Whip marshmallow buttercream at high speed for at least 5-7 minutes to achieve a light, fluffy texture that pipes beautifully.
Sprinkle Application Pro Tip 🎉
Apply sprinkles immediately after frosting while the buttercream is still soft to ensure maximum sprinkle adhesion and a professional finish.
