Ingredients
  

For the Cake:

  • 1 box white or vanilla cake mix plus ingredients listed on the box
  • or
  • cups all-purpose flour
  • teaspoons baking powder
  • ½ teaspoon salt
  • ¾ cup unsalted butter softened
  • cups granulated sugar
  • 4 large eggs
  • 1 cup milk
  • 2 teaspoons vanilla extract

For the Frosting:

  • 2 cups heavy whipping cream
  • ½ cup powdered sugar
  • 1 teaspoon vanilla extract

For Decorating:

  • 1 cup fresh blueberries
  • cups sliced strawberries
  • Optional: additional raspberries for extra red color

Instructions
 

Bake the Cake:

  • Preheat oven to 350°F (175°C). Prepare a 9x13-inch pan. Make and bake the cake according to box directions or homemade version. Cool completely.

Make Whipped Frosting:

  • In a large bowl, beat whipping cream, powdered sugar, and vanilla until stiff peaks form.

Frost & Decorate:

  • Spread whipped cream over cooled cake. Arrange blueberries in the top-left corner as the “stars,” and alternate strawberry slices in rows to form red “stripes.”

Chill & Serve:

  • Chill for 30 minutes before slicing for best results. Serve cold.

Notes

  • Shortcut: Use store-bought cake and frosting for a quicker version.
  • Make Ahead: Cake and whipped topping can be made a day ahead; decorate just before serving.
  • Fruit Swap: Use raspberries instead of strawberries or combine both for extra colour.
  • Stabilised Cream: Add 1 tablespoon instant pudding mix for a more stable whipped topping.
  • Serving Tip: Perfect centerpiece dessert for July 4th, Memorial Day, or Veterans Day.
