  • 1 box angel food cake mix
  • ½ cup water (plus additional as per cake mix package)
  • Food coloring: 4 drops each of green, purple, and pink
  • 2 cups mini marshmallows
  • ¾ cup powdered sugar
  • 4 tbsp unsalted butter
  • 10 drops blue food coloring
  • Multicolor sprinkles (for decoration)


  1. Prepare the Cake:
    • Preheat your oven according to the angel food cake mix instructions. Line a 9-inch round cake pan with parchment paper and grease it lightly.
    • Prepare the cake mix with the specified amount of water. Once smooth, divide the batter into three separate bowls.
    • Color each portion with green, purple, and pink food coloring, mixing well to ensure vibrant colors.
    • Gently pour the colored batters into the prepared pan to create a marbled effect. Bake according to the package directions until a toothpick inserted comes out clean.
    • Allow the cake to cool completely, then invert onto a serving plate and remove the parchment paper.
  2. Make the Marshmallow Frosting:
    • In a medium skillet over medium heat, combine ½ cup water, mini marshmallows, powdered sugar, butter, and blue food coloring.
    • Cook, stirring continuously, until the marshmallows are completely melted and the mixture is smooth.
    • Pour the warm marshmallow mixture over the cooled cake, using a spatula to spread evenly.
  3. Decorate:
    • Immediately sprinkle the cake with multicolor sprinkles to enhance its magical appearance.
    • Refrigerate the cake for at least 2 hours to set the frosting before serving.

Preparation Time: Under 30 minutes (excluding baking and cooling time)

Tips for a Magical Cake:

  • For an even more personalized touch, substitute the box mix with your favorite homemade vanilla cake recipe.
  • Consider experimenting with different molds to shape your cake like an actual unicorn.
  • For a less sweet option, you might want to opt for a classic buttercream frosting in place of the marshmallow frosting.
  • To add a surprise element, fill the center of the cake with colorful candies or make it a piñata cake.
  • If decorating with sprinkles, apply them while the marshmallow frosting is warm so they stick well and create a shimmering effect.


This Fluffy Unicorn Cake is guaranteed to be a hit at any party, offering not just a delicious treat but a burst of joy and color that will make any celebration a bit more magical. Perfect for both children and adults alike, it’s a creative way to bring some enchantment to your dessert table!
