Ingredients

Scale
  • 1 box yellow cake mix (about 15.25 oz / 432 g)
  • 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
  • 1/4 cup powdered sugar (30 g), sifted
  • 1 teaspoon pure vanilla extract
  • 2 cups fresh strawberries, hulled and sliced (about 300 g)
  • 1 cup fresh blueberries (about 150 g)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking pan with butter or non-stick spray, then set aside.
  2. In a large bowl, combine the yellow cake mix, 1 cup of water, 1/3 cup vegetable oil, and 3 large eggs. Beat with an electric mixer on medium speed for 2 minutes until smooth.
  3. Pour the batter into the prepared pan and spread evenly with a spatula. Tap the pan gently on the counter to release any air bubbles.
  4. Bake for 28-32 minutes. Check doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs.
  5. Cool the cake completely in the pan on a wire rack for at least 45 minutes.
  6. Chill a medium bowl and beaters in the fridge for 10-15 minutes. Pour 2 cups of cold heavy cream into the chilled bowl. Add 1/4 cup powdered sugar and 1 teaspoon vanilla extract. Beat on medium-high speed until soft peaks form, about 3-4 minutes.
  7. Spread the whipped cream evenly over the cooled cake using an offset spatula or the back of a spoon.
  8. Arrange the berries as the flag design: place blueberries in the top-left corner to form the blue field, then use sliced strawberries to create stripes across the remaining sections, alternating rows of berries and whipped cream.
  9. Chill the cake for at least 1 hour before serving to help the whipped cream set and flavors meld.
  10. Pat berries dry with a paper towel before placing them on the cake if they are particularly juicy to prevent the whipped cream from becoming watery.

Notes

Do not spread whipped cream on warm cake to avoid melting. Chill bowl and beaters before whipping cream for best results. Pat berries dry if juicy to prevent sogginess. Use fresh berries for best color and texture. Cake can be made a day ahead and topped just before serving. Avoid freezing due to whipped cream texture changes.
