Ingredients

Scale
  • 1 box white cake mix (about 15.25 oz / 432 g)
  • 3 large eggs, room temperature
  • 1 cup water (240 ml)
  • 1/3 cup vegetable oil (80 ml)
  • 1 packet (3 oz / 85 g) strawberry gelatin (red layer)
  • 1 packet (3 oz / 85 g) blueberry or berry-flavored gelatin (blue layer)
  • 2 cups boiling water (480 ml), divided
  • 1 cup cold water (240 ml), divided
  • 8 oz cream cheese, softened (225 g)
  • 1 cup sour cream (240 ml)
  • 1 cup powdered sugar (120 g)
  • 1 teaspoon vanilla extract (5 ml)
  • Optional: whipped cream or cool whip
  • Optional: fresh berries (strawberries, blueberries, raspberries)

Instructions

  1. Preheat oven to 350°F (175°C). In a large bowl, combine white cake mix, eggs, water, and vegetable oil. Beat on medium speed for 2 minutes until smooth.
  2. Pour batter evenly into a 9×13 inch baking pan. Bake for 30-35 minutes or until a toothpick inserted comes out clean. Let cake cool completely, about 1 hour.
  3. Using a wooden skewer or thick toothpick, poke holes all over the surface of the cooled cake about 1 inch apart, going halfway through the cake.
  4. In two separate heatproof bowls, dissolve each packet of gelatin in 1 cup boiling water. Stir until fully dissolved.
  5. Add 1/2 cup cold water to each bowl and stir. Let gelatin cool to room temperature but not set, about 15-20 minutes, until thick but pourable.
  6. Beat softened cream cheese, sour cream, powdered sugar, and vanilla extract together until smooth and creamy.
  7. Spoon half of the strawberry gelatin evenly over the cake, allowing it to seep into the holes.
  8. Dollop half of the cream cheese mixture over the top and gently spread with a spatula.
  9. Repeat layering with blueberry gelatin and remaining cream cheese mixture for red, white, and blue effect.
  10. Cover cake loosely with plastic wrap and refrigerate for at least 2 hours or until gelatin layers are fully set.
  11. Before serving, top with whipped cream and fresh berries if desired. Slice into squares and serve chilled.

Notes

Ensure gelatin is cooled to room temperature but still pourable before pouring over cake to prevent melting. Space holes about 1 inch apart to avoid cake breaking. Soften cream cheese well for smooth creamy layer. Chill cake at least 2 hours or overnight for best texture. Optional lemon juice in cream cheese mixture adds subtle tang.
