Ingredients

Scale

Bars:

  • 15.25 ounces funfetti cake mix
  • 1 large egg
  • ½ cup salted butter (1 stick), melted
  • ½ cup heavy cream

Frosting:

  • 8 ounces cream cheese, room temperature
  • ½ cup salted butter (1 stick), room temperature
  • 3½ cups powdered sugar
  • 1 to 3 tablespoons heavy cream
  • 1 teaspoon vanilla extract
  • Purple food coloring
  • Blue food coloring
  • Sprinkles (optional, for garnish)

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F and lightly grease a 9×13 inch baking pan or line it with parchment paper to prevent sticking.
  2. Mix Cake Batter: In a large mixing bowl, combine the funfetti cake mix, egg, melted butter, and heavy cream. Stir thoroughly until all ingredients are well incorporated into a smooth batter.
  3. Spread Batter and Bake: Evenly spread the batter into the prepared pan, smoothing the top. Bake for 20 to 25 minutes or until a toothpick inserted into the center comes out clean, indicating the bars are fully baked.
  4. Cool Bars: Remove from oven and allow the bars to cool completely in the pan to ensure the frosting adheres well and doesn’t melt.
  5. Prepare Frosting Base: Using a hand or stand mixer, beat the cream cheese and softened butter together in a large bowl until smooth and creamy.
  6. Add Powdered Sugar: Gradually beat in the powdered sugar, about ½ cup at a time, mixing on medium speed until the frosting is light and fluffy.
  7. Incorporate Heavy Cream and Vanilla: Add the heavy cream and vanilla extract slowly, one tablespoon at a time, while beating on high speed until the frosting reaches a light and spreadable consistency.
  8. Color the Frosting: Divide the frosting into two separate bowls. Fold purple food coloring into one bowl and blue food coloring into the other until you reach your desired shades.
  9. Frost the Bars: Spread the colored frostings alternately over the cooled bars. Use a spoon or flat spatula to swirl the colors together for a beautiful marbled effect.
  10. Add Sprinkles and Serve: Optionally, garnish with sprinkles. Cut into bars and serve chilled or at room temperature.

Notes

  • Storage: Keep the Unicorn Bars refrigerated due to the dairy frosting. They will stay fresh for up to 5 days in the fridge.
  • Freezing: Wrap bars tightly and store in a freezer-safe container for up to 2 months. Thaw before serving.
  • Variations: Use any cake mix flavor like chocolate, lemon, strawberry, or yellow. Experiment with different extracts and substitute liquids like orange juice or flavored milk in the frosting.
  • Frosting Alternatives: You can replace the cream cheese frosting with chocolate frosting, buttermilk frosting, or whipped topping for a different taste and texture.
