Description

These vibrant and fun Unicorn Bars are a delightful twist on classic funfetti cake, layered with a tangy cream cheese frosting tinted in whimsical purple and blue hues. Perfect for parties or a cheerful dessert, this recipe yields moist, colorful bars topped with a luscious, fluffy frosting and optional sprinkles for extra sparkle.


Ingredients

Bars

  • 15.25 ounces box 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
  • 1-3 tablespoons heavy cream
  • 1 teaspoon vanilla extract
  • Purple and blue food coloring
  • Sprinkles (optional garnish)


Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and lightly grease or line a 9×13 inch baking pan with parchment paper to prevent sticking and allow easier removal.
  2. Make the batter: In a large mixing bowl, combine the funfetti cake mix, egg, melted butter, and heavy cream until the batter is evenly mixed without lumps.
  3. Bake the bars: Spread the batter evenly into the prepared pan and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean, indicating the bars are cooked through.
  4. Cool the bars: Allow the baked bars to cool completely in the pan to ensure the frosting adheres properly without melting.
  5. Prepare the frosting: In a large bowl, beat together the room temperature cream cheese and butter until smooth and creamy using a hand mixer or stand mixer.
  6. Add powdered sugar: Gradually beat in the powdered sugar, about ½ cup at a time, until the frosting becomes light and fluffy in texture.
  7. Adjust consistency: Add heavy cream one tablespoon at a time along with vanilla extract while beating on high until the frosting reaches a light, fluffy, and spreadable consistency.
  8. Color the frosting: Divide the frosting evenly into two separate bowls. Fold purple food coloring into one bowl and blue into the other until your desired shades are achieved.
  9. Frost the bars: Alternately spread the colored frostings over the cooled bars and swirl gently using a spoon or flat spatula to create a beautiful marbled effect.
  10. Decorate and serve: Sprinkle optional sprinkles on top for extra fun, then cut into 16 bars and serve.

Notes

  • Ensure cream cheese and butter are at room temperature for smooth frosting without lumps.
  • Adjust food coloring amounts gradually to achieve the perfect intensity without overpowering flavor.
  • For easier slicing, refrigerate the frosted bars for 30 minutes before cutting.
  • Store leftover bars tightly covered in the refrigerator for up to 5 days.
  • Use gluten-free funfetti cake mix if you prefer a gluten-free version.
