Ingredients
Scale
- 1 box vanilla 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), cold
- 1/4 cup powdered sugar (30 g)
- 1 tsp pure vanilla extract (5 ml)
- 2 cups fresh strawberries, hulled and sliced (about 300 g)
- 1 cup fresh blueberries (150 g)
Instructions
- Preheat your oven to 350°F (175°C) and lightly grease your 9×13-inch baking pan with butter or non-stick spray. Line the bottom with parchment paper if desired.
- In a large mixing bowl, combine the vanilla cake mix, water, vegetable oil, and eggs. Beat on medium speed for 2 minutes until smooth and thick but pourable.
- Pour the batter into the prepared pan, spreading evenly. Tap the pan gently on the counter to release air bubbles.
- Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Check starting at 30 minutes to avoid overbaking.
- Cool the cake completely in the pan on a wire rack, about 1 hour.
- Chill mixing bowl and beaters for 15 minutes. Pour cold heavy cream into the bowl, add powdered sugar and vanilla extract. Beat on medium-high speed until soft peaks form, about 3-5 minutes.
- Spread whipped cream evenly over the cooled cake in a 1/4 to 1/2 inch thick layer.
- Arrange blueberries in the top-left corner to mimic the flag’s blue field. Line up sliced strawberries in neat horizontal rows for the red stripes, leaving white space from the whipped cream.
- Chill the assembled cake in the refrigerator for at least 30 minutes before serving.
Notes
Chill mixing bowl and beaters before whipping cream for better volume. Use room temperature eggs for better cake rise. Arrange blueberries first for a neat flag pattern. Add a teaspoon of cornstarch to whipped cream for extra stability if serving outdoors. Use a sharp knife dipped in hot water for clean slices. Frozen berries can be used if thawed and drained well.
