Ingredients

Scale
  • 1 box white cake mix (around 15.25 oz / 432 g) – Pillsbury recommended
  • 1 cup water (240 ml)
  • 1/3 cup vegetable oil (80 ml)
  • 3 large eggs, room temperature
  • 2 cups heavy whipping cream (480 ml), chilled
  • 1/2 cup powdered sugar (60 g), sifted
  • 1 tsp pure vanilla extract
  • 1 pint strawberries (about 300 g), hulled and sliced
  • 1 pint blueberries (about 150 g), washed and dried
  • Optional: fresh raspberries or blackberries for extra color and flavor

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13 inch pan with butter or non-stick spray and lightly dust with flour.
  2. In a large bowl, combine the white cake mix, water, vegetable oil, and eggs. Beat with an electric mixer at medium speed for about 2 minutes until smooth.
  3. Pour the batter evenly into the prepared pan. Bake for 28-32 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  4. Remove the cake from the oven and let it cool completely in the pan on a wire rack, about 1 hour.
  5. Chill mixing bowl and beaters for 15 minutes. Pour heavy whipping cream, powdered sugar, and vanilla extract into the bowl. Beat at medium-high speed until soft peaks form.
  6. Spread half of the whipped cream evenly over the cooled cake.
  7. Arrange sliced strawberries in neat stripes on one side to mimic the flag’s red stripes.
  8. Place blueberries densely on the opposite corner to represent the blue field of stars.
  9. Cover the remaining cake surface with the rest of the whipped cream, smoothing it out gently.
  10. Refrigerate the assembled cake for at least 1 hour before serving to let flavors meld and cream firm up.

Notes

Chill the mixing bowl and beaters before whipping cream to achieve soft peaks. Pat berries dry to avoid soggy cake. Use a serrated knife and wipe clean between cuts for neat slices. Refrigerate cake after assembly for best texture. Can substitute gluten-free cake mix or coconut cream for dietary adaptations.
