Ingredients
  

Brownies (box mix)
  • 1 box fudge brownie mix Use the box’s called-for ingredients as directed.
Topping
  • 2 cup powdered sugar
  • 4 oz cream cheese softened
  • 2 tbsp butter softened
  • 1 tsp vanilla extract
  • 2 tbsp milk use 2–3 tbsp for spreadable texture
  • 1 cup fresh strawberries sliced
  • 1 cup fresh blueberries

Equipment

  • 1 sheet pan

Method
 

Bake the brownies
  1. Bake brownies in a 9x13 pan according to the package directions and keep oven at the box temperature. Let the brownies cool completely, at least 1 hour, until no longer warm.
Make the white vanilla frosting
  1. Beat cream cheese, butter, powdered sugar, vanilla extract, and milk together until smooth and spreadable. Stop and scrape as needed so there are no dry pockets.
Decorate in patriotic rows
  1. Spread the cream cheese frosting in an even layer over the cooled brownies, covering all edges. Use an offset spatula or the back of a spoon to level the surface.
  2. In the upper left corner, arrange a rectangle of blueberries tightly packed to form the canton. Press them lightly into the frosting so the rows hold their shape.
  3. Create red stripes across the rest of the brownies using rows of sliced strawberries laid flat. Lay each row in the same direction for clean, straight lines.
  4. Leave alternating gaps between strawberry rows so the white frosting shows through as the stripes. Aim for evenly spaced gaps for a flag-like look.
Chill and slice
  1. Refrigerate for 30 minutes to set the frosting. Slice into squares after chilling so the decorated pattern stays sharp.

Notes

For the cleanest flag design, cool the brownies fully before frosting and keep the frosting at a thick, spreadable consistency—add milk 1 teaspoon at a time if it feels too stiff. Store leftovers in the refrigerator up to 4 days; freeze brownies without best visual fidelity for up to 2 months. If you want a lighter option, use reduced-fat cream cheese and butter, then adjust milk slightly to keep the frosting smooth and spreadable.
