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. Prepare the bars base: In a mixing bowl, combine the funfetti cake mix, large egg, melted salted butter, and heavy cream. Mix until a smooth, thick batter forms.
  2. Bake the base: Preheat your oven to 350°F (175°C). Pour the batter into a greased or parchment-lined 9×13-inch baking pan and evenly spread it. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Allow to cool completely.
  3. Make the cream cheese frosting: In a bowl, beat the room temperature cream cheese and salted butter together until smooth and creamy. Gradually add in powdered sugar, mixing until fully incorporated. Add vanilla extract and 1 to 3 tablespoons of heavy cream to achieve a spreadable consistency.
  4. Color the frosting: Divide the frosting into two portions. Tint one portion with purple food coloring and the other with blue food coloring, mixing until the colors are uniform.
  5. Frost the bars: Once the bars are completely cooled, frost the top with the colored frostings using a spatula or piping bag. You can layer or swirl the colors for a unicorn effect.
  6. Garnish and serve: Optionally, sprinkle with colorful sprinkles on top for an extra festive touch. Cut into bars and enjoy!

Notes

  • Allow the bars to cool completely before frosting to prevent melting or slipping of the frosting.
  • You can adjust the amount of food coloring to get your preferred shade of purple and blue.
  • For a dairy-free version, substitute cream cheese and butter with vegan alternatives.
  • Store the bars in an airtight container in the refrigerator for up to 4 days.
  • Bring bars to room temperature before serving for best texture and flavor.
