Ingredients

Scale
  • 1 box white cake mix (plus ingredients called for on the box, usually eggs, oil, and water)
  • 1 cup sour cream
  • 1 package (3 oz) red cherry gelatin
  • 1 package (3 oz) blue raspberry gelatin
  • 1 package (3 oz) unflavored gelatin
  • 2 cups boiling water (divided for dissolving gelatin)
  • 1 cup cold water
  • 1 cup sweetened condensed milk
  • 2 cups heavy whipping cream
  • 1/4 cup powdered sugar
  • 1 teaspoon vanilla extract
  • Optional: fresh blueberries and small strawberries for topping

Instructions

  1. Preheat oven to 350°F (175°C). Prepare the white cake mix according to package instructions, adding 1 cup sour cream for extra moisture.
  2. Pour batter into a greased 9×13-inch baking pan and bake for 30-35 minutes or until a toothpick inserted comes out clean. Let cool completely, about 1 hour.
  3. Using a toothpick or fork, gently poke holes all over the cooled cake about 1 inch apart, deep enough to reach the bottom but not break the cake.
  4. Dissolve red cherry gelatin in 1 cup boiling water. Stir until dissolved, cool slightly for 5 minutes, then pour evenly over one-third of the cake holes. Refrigerate for 20 minutes to set.
  5. Dissolve unflavored gelatin in 1/2 cup boiling water. Stir in 1 cup sweetened condensed milk and 1/2 cup cold water. Mix well and pour over the middle third of the cake. Chill for 20 minutes.
  6. Dissolve blue raspberry gelatin in 1 cup boiling water. Cool for 5 minutes and pour over the final third of the cake. Refrigerate and chill for at least 2 hours until fully set.
  7. In a cold bowl, whip 2 cups heavy cream with 1/4 cup powdered sugar and 1 teaspoon vanilla extract until stiff peaks form.
  8. Spread whipped cream evenly over the chilled cake.
  9. Optional: Decorate with fresh blueberries and small strawberries or pipe stars with remaining whipped cream to mimic the flag’s stars.

Notes

Do not rush the jello setting between layers to avoid colors mixing and becoming muddy. Use a gentle hand when spreading the whipped topping to keep the flag pattern intact. For dairy-free topping, substitute heavy cream with whipped coconut cream. Use gluten-free cake mix for gluten-sensitive guests.
