For the Cake:

  • 1 box White or Vanilla Cake Mix
  • 3 Large Eggs
  • ⅓ cup Vegetable or Canola Oil
  • 1 cup Water or Milk

For the Pudding:

  • 2 boxes (3.4 oz each) Instant Vanilla Pudding Mix
  • 3 cups Milk

For the Whipped Cream Frosting:

  • 1¼ cups Heavy Whipping Cream
  • ¼ cup Confectioners’ Sugar

For Decoration:

  • Rainbow Sprinkles
  • Assorted Food Coloring


  1. Prepare the Oven and Pan:
    • Preheat the oven to 350°F.
    • Grease a 13×9 inch baking pan with cooking spray.
  2. Make the Colorful Batter:
    • Beat the cake mix, eggs, oil, and water or milk until smooth.
    • Divide the batter into 5 or 6 bowls, and tint each with different food coloring.
    • Randomly spoon the colored batters into the pan without mixing.
  3. Bake:
    • Bake for 25-30 minutes until a toothpick comes out clean.
    • Let cool completely in the pan on a wire rack.
  4. Add Pudding:
    • Whisk the pudding mix and milk until smooth.
    • Poke holes in the cooled cake with the end of a wooden spoon.
    • Pour the pudding over the cake, ensuring it fills the holes.
    • Refrigerate for at least 2 hours.
  5. Whipped Cream Frosting:
    • In a chilled bowl, beat the heavy cream and confectioners’ sugar until stiff peaks form.
    • Spread over the pudding layer.
  6. Decorate:
    • Sprinkle generously with rainbow sprinkles.


  • Smooth Release: Ensure the cake releases smoothly from the pan by thoroughly greasing it.
  • Color Layering: Be creative with how you layer the colors for a fun visual effect.
  • Pudding Setting: Ensure the pudding sets completely to avoid a soggy cake base.


Q: Can I use regular milk instead of water for the cake mix?
A: Yes, using milk instead of water will give the cake a richer flavor and denser texture.

Q: How long should I wait before adding the pudding?
A: Allow the cake to cool completely to avoid melting the pudding when added.

Q: Can the whipped cream frosting be made ahead of time?
A: It’s best to make it just before serving to maintain its fluffiness.
