Ingredients
Scale
- 1 box white cake mix (about 15.25 oz / 432 g)
- 1 cup water (240 ml)
- 1/3 cup vegetable oil (80 ml) or melted coconut oil
- 3 large eggs, room temperature
- 5 small boxes (3 oz / 85 g each) Jello gelatin mix in assorted flavors (red, orange, yellow, green, purple)
- Boiling water (amount per Jello package instructions)
- Cold water or ice (amount per Jello package instructions)
- 2 cups heavy whipping cream (480 ml), cold
- 1/2 cup powdered sugar (60 g)
- 1 tsp pure vanilla extract
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan lightly with butter or non-stick spray.
- In a large bowl, combine the cake mix, 1 cup water, 1/3 cup vegetable oil, and 3 large eggs. Beat on medium speed with an electric mixer for about 2 minutes until smooth.
- Pour the batter evenly into the prepared pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let cool for 10 minutes but keep warm.
- Using a fork or skewer, poke holes all over the cake surface about 1 inch apart.
- Prepare each jello flavor in separate bowls according to package instructions. Let cool slightly but do not set.
- Carefully spoon or pour each jello flavor evenly over different sections of the cake, filling the holes. Refrigerate for at least 4 hours or until jello is fully set.
- Beat the cold heavy cream with powdered sugar and vanilla extract on high speed until stiff peaks form (3-5 minutes).
- Spread the whipped cream frosting evenly over the cake using a spatula.
- Chill the cake for another hour to let the whipped cream firm up. Slice with a sharp knife dipped in hot water for clean cuts. Serve cold.
Notes
Do not overbake the cake; a slightly underbaked cake absorbs jello better. Poke and pour jello while the cake is still warm for best results. Chill the cake for at least 4 hours or overnight to allow jello to set fully. Keep cream and tools cold when whipping to achieve stiff peaks. Use a sharp knife dipped in hot water for clean slices.
