Ingredients

Scale
  • 1 box white or yellow cake mix (about 15.25 oz / 432 g)
  • Ingredients called for on the cake mix box (usually eggs, oil, and water)
  • 2 cups heavy whipping cream (480 ml), chilled
  • 1/2 cup powdered sugar (60 g)
  • 1 teaspoon vanilla extract
  • 1 cup fresh strawberries, sliced (about 150 g)
  • 1 cup fresh blueberries (about 150 g)
  • 1 cup fresh raspberries or blackberries (optional)
  • Optional: 1/2 cup crushed pecans or walnuts
  • Optional: Food coloring gel (red and blue)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch (23×33 cm) pan or line it with parchment paper.
  2. Follow the instructions on your cake mix box, combining the mix, eggs, oil, and water as directed. Beat on medium speed for about 2 minutes until smooth.
  3. Pour the batter evenly into the prepared pan. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
  4. Remove the cake from the oven and let it cool in the pan on a wire rack for about 15 minutes. Then cool completely before frosting.
  5. In a chilled bowl, combine heavy whipping cream, powdered sugar, and vanilla extract. Beat with an electric mixer on high speed until stiff peaks form (3–5 minutes).
  6. Spread an even layer of whipped cream over the cooled cake. Arrange sliced strawberries, blueberries, and raspberries or blackberries in sections to mimic a flag pattern.
  7. Cover the cake loosely with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
  8. Bring the cake out of the fridge about 15 minutes before serving. Slice with a sharp knife and enjoy.

Notes

Keep the cream chilled until ready to whip for best fluffy results. Use a serrated knife to slice the cake to avoid squishing layers. Fresh berries are best; if using frozen, thaw and drain well. Assemble the cake the night before to let flavors meld and make slicing easier.
