Ingredients
- 1 (15.25-ounce) box of white cake mix
- 1 cup cold water
- ½ cup vegetable oil
- 4 egg whites, room temperature
- 3 cups boiling water
- 1 (3-ounce) box of strawberry gelatin mix
- 1 (3-ounce) box of orange gelatin mix
- 1 (3-ounce) box of lemon gelatin mix
- 1 (3-ounce) box of lime gelatin mix
- 1 (3-ounce) box of berry blue gelatin mix
- Red, orange, yellow, green, and blue food color gel
- 1 (8-ounce) container of Cool Whip whipped topping, thawed

Directions
- Preheat the Oven:
- Set your oven to 350°F (175°C). Grease a 9×13 inch baking dish.
- Mix and Bake the Cake:
- In a large bowl, combine the cake mix, water, oil, and egg whites. Beat until smooth.
- Pour the mixture into the prepared baking dish. Bake for 25-28 minutes or until a toothpick inserted into the center comes out clean.
- Poke Holes:
- Allow the cake to cool slightly, then use a chopstick to poke holes throughout the cake at regular intervals. Ensure the cake cools completely afterward.
- Prepare Gelatin:
- In separate bowls, dissolve each box of gelatin mix in ½ cup of boiling water. Add 5-7 drops of corresponding food color to each gelatin mixture.
- Add Gelatin to Cake:
- Carefully pour or spoon the colored gelatin into the holes in the cake, alternating colors for a rainbow effect. Avoid overfilling the holes.
- Chill the Cake:
- Cover the cake with plastic wrap and refrigerate for at least 2 hours to allow the gelatin to set.
- Frost and Garnish:
- Once chilled, spread the whipped topping evenly over the cake. If desired, sprinkle with rainbow sprinkles for an extra festive look.
- Serve:
- Slice the cake and serve chilled for a refreshing, fun dessert.
Tips
- Perfect Holes: Use a chopstick for making holes as it provides the perfect diameter—not too large to avoid the gelatin from spilling out.
- Added Fun: For a more creative presentation, consider using cookie cutters to cut gelatin squares into fun shapes to place on top of the cake.
- Storage: Keep the cake refrigerated until ready to serve to ensure it remains fresh and the gelatin stays firm.
