For the Cake Layer:

  • Betty Crocker™ Super Moist™ White Cake Mix: 1 box
  • Butter, melted: 1/2 cup
  • Egg: 1
  • Milk: 2/3 cup
  • Betty Crocker™ Gel Food Colors: Neon Pink, Orange, Purple, Yellow, Green, Blue

For the Cheesecake Layer:

  • Cream Cheese, softened: 1 1/2 blocks (12 oz.)
  • Sugar: 1/3 cup
  • Egg: 1
  • Vanilla Extract: 1 teaspoon
  • Additional milk for thinning batter colors: 9 teaspoons


  1. Prepare the Oven and Pan:
    • Preheat the oven to 325°F (163°C).
    • Line a 9×13-inch pan with non-stick foil or parchment paper and lightly spray with baking spray.
  2. Make the Rainbow Cake Batter:
    • In a mixing bowl, combine the cake mix, melted butter, egg, and milk until smooth.
    • Divide the batter evenly among six bowls. Add a different gel food color to each bowl and mix well.
    • Spoon teaspoonfuls of the various colored batters into the prepared pan, alternating colors to create a rainbow effect. With wet hands, gently press the batter to flatten.
  3. Prepare the Cheesecake Layer:
    • In another bowl, blend cream cheese and sugar until smooth. Mix in the egg and vanilla extract until well incorporated.
    • Pour this cheesecake mixture over the colored cake batter in the pan.
  4. Create the Swirl Effect:
    • Thin out each of the reserved colored batters with a teaspoon of milk per color.
    • Drizzle these thinned batters over the cheesecake layer. Using a fork or the tip of a knife, swirl the colors gently to create a marbled effect.
  5. Baking:
    • Bake in the preheated oven for 20 minutes. Cover with foil to prevent excessive browning and continue baking for another 14-20 minutes, or until the cheesecake is set and the edges are lightly golden.
    • Remove from oven and let cool to room temperature, then refrigerate for at least 2 hours before cutting into bars.
