Ingredients Equipment Method Notes

Ingredients
  

Brownie base
  • 1 box fudge brownie mix Use the mix package instructions for eggs and water or oil called for on the box.
Topping and flag decoration
  • 2 cup powdered sugar
  • 4 oz cream cheese Softened.
  • 2 tbsp butter Softened.
  • 1 tsp vanilla extract
  • 2.5 tbsp milk Use 2–3 tbsp to reach spreadable consistency.
  • 1 cup fresh strawberries Sliced.
  • 1 cup fresh blueberries

Equipment

  • 1 sheet pan

Method
 

Bake and cool the brownies
  1. Heat the oven and bake the fudge brownie mix in a 9x13 pan according to the package directions. Bake for the time listed on the box until set in the center.
  2. Let the brownies cool completely in the pan for at least 1 hour. Leave them undisturbed until fully room temperature so the frosting spreads cleanly.
Make the vanilla cream cheese frosting
  1. In a mixing bowl, beat the cream cheese, butter, and powdered sugar together until smooth. Mix until no lumps remain and the mixture looks thick and uniform.
  2. Add the vanilla extract and milk, then beat again until smooth and spreadable. Adjust with 1–2 tsp more milk if needed for a silky, pourable frosting texture.
Frost and decorate as an American flag
  1. Spread the cream cheese frosting in an even layer over the cooled brownies. Cover all edges so the fruit decoration sits on a solid base.
  2. In the upper left corner, arrange blueberries tightly packed to form a rectangle. Press lightly so the canton holds together.
  3. Create red stripes by laying sliced strawberries flat across the remaining area. Arrange the slices in straight rows for clean lines.
  4. Leave alternating gaps between strawberry rows so the white frosting shows through. Aim for even spacing to form distinct red-white-blue stripes.
  5. Refrigerate the brownies for 30 minutes to set the frosting. Chill until the frosting feels firm to the touch before cutting.
Slice and serve
  1. Cut the brownies into squares and serve. Use a clean, sharp cut to keep the flag pattern crisp.

Notes

Pro tip: for the sharpest flag lines, slice strawberries evenly and press each row down lightly so they don’t slide when you chill. Store covered in the refrigerator up to 4 days; the frosting will set more firmly overnight. Freezing is not recommended because the fresh berries can bleed when thawed. For a dairy-light swap, use vegan cream cheese and vegan butter (softened) in the frosting for a similar texture.
