  • 1 box white cake mix
  • 1 can (12 oz) clear soda (like Sprite or 7UP)
  • Food coloring in rainbow colors (red, orange, yellow, green, blue, indigo, violet)


  1. Prep: Preheat your oven according to the cake mix instructions. Grease a round cake pan and set aside.
  2. Mix: In a large bowl, combine the cake mix with the can of soda. Mix until well incorporated.
  3. Color the Batter: Divide the batter evenly among several bowls, depending on how many colors you are using. Add food coloring to each bowl to create vibrant colors.
  4. Layer the Batter: Pour each colored batter into the prepared pan, one at a time, carefully layering the colors to maintain distinct bands.
  5. Bake: Follow the baking instructions on the cake mix box, typically around 25-30 minutes, or until a toothpick comes out clean.
  6. Cool and Serve: Allow the cake to cool completely before removing from the pan. Serve as is or with a light dusting of powdered sugar.


  • Use a clear soda to keep the cake light and to enhance the color brightness.
  • Pour each layer of batter gently and directly in the center to create a neat layered effect.
  • Ensure each layer is poured evenly to achieve the striking rainbow effect when sliced.


Q: Can I use any type of soda for this recipe? A: It’s best to use a clear soda like Sprite or 7UP to ensure the colors remain vibrant and the flavor neutral.

Q: What if I want to make the cake less sweet? A: You can opt for a diet or zero-sugar version of the soda to reduce the overall sweetness of the cake.
