Cake Ingredients
- 15.25 ounces box of white cake mix
- 1 cup water
- ½ cup vegetable oil
- 4 egg whites, room temperature
Gelatin Layers
- 3 cups boiling water, divided
- 3 ounce box strawberry gelatin mix
- 3 ounce box orange gelatin mix
- 3 ounce box lemon gelatin mix
- 3 ounce box lime gelatin mix
- 3 ounce box berry blue gelatin mix
- Red, orange, yellow, green, and blue food color gel (5-7 drops each)
Topping and Garnish
- 8 ounce container whipped topping, thawed
- Rainbow sprinkles (optional garnish)
Instructions
- Prepare the White Cake Batter: In a large mixing bowl, combine the white cake mix, 1 cup water, ½ cup vegetable oil, and 4 egg whites at room temperature. Beat the mixture with an electric mixer for about 2 minutes until smooth and well blended.
- Bake the Cake: Pour the cake batter evenly into a greased 9×13 inch baking pan. Bake in a preheated oven at 350°F (175°C) for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan.
- Prepare the Gelatin Mixtures: While the cake cools, dissolve each 3-ounce box of gelatin (strawberry, orange, lemon, lime, and berry blue) separately in 3/4 cup of boiling water. Stir each mixture until completely dissolved. Add 5-7 drops of the corresponding food color gel to intensify the color and stir well.
- Layer the Gelatin Over the Cake: Once the cake is completely cooled, carefully pour the first gelatin color (red/strawberry) evenly over the cake. Refrigerate until firm, about 45 minutes to 1 hour. Repeat this process for each other gelatin color in order (orange, yellow/lemon, green/lime, blue/berry blue), allowing each layer to set fully before adding the next to create vibrant, distinct layers.
- Add the Whipped Topping: After the final gelatin layer is set, spread the thawed whipped topping evenly over the top of the cake for a creamy finish.
- Garnish and Serve: Optionally sprinkle rainbow sprinkles over the whipped topping to add a festive, colorful touch. Chill the cake until ready to serve for the best texture and flavor.
Notes
- Ensure the cake is completely cooled before pouring gelatin layers to prevent melting and blending of colors.
- Use gel food coloring as it provides more vibrant hues than liquid coloring.
- Allow each gelatin layer to fully set in the refrigerator to maintain distinct layers.
- You can substitute the white cake mix with homemade white cake batter if preferred.
- For easier cutting, run a knife under warm water and dry it before slicing the cake.
