Ingredients Equipment Method Notes

Ingredients
  

Brownie base (follow box instructions for mix plus required add-ins)
  • 1 box fudge brownie mix
Topping
  • 2 cup powdered sugar
  • 4 oz cream cheese softened
  • 2 tbsp butter softened
  • 1 tsp vanilla extract
  • 2 tbsp milk start with 2 tbsp, add up to 3 tbsp as needed to make frosting spreadable
  • 1 cup fresh strawberries sliced
  • 1 cup fresh blueberries

Equipment

  • 1 sheet pan

Method
 

Bake and cool brownies
  1. Bake the brownies in a 9x13 pan according to package directions until set in the center. Visually look for a slightly cracked top and the edges pulling away from the pan.
  2. Let the brownies cool completely, at least 1 hour, before frosting. The surface should be fully cool to the touch so the frosting won’t melt.
Make vanilla cream cheese frosting
  1. Beat cream cheese, butter, powdered sugar, vanilla extract, and milk together until smooth and spreadable. Stop and scrape the bowl as needed for a thick, creamy frosting that holds its shape.
Frost and decorate flag
  1. Spread the frosting in an even layer over the cooled brownies. Use an offset spatula or the back of a spoon to make the surface level.
  2. In the upper left corner, arrange a rectangle of blueberries tightly packed to form the canton. Press gently so berries sit close together with minimal gaps.
  3. Create red stripes across the rest of the brownies using rows of sliced strawberries laid flat. Lay the slices in straight lines so each row reads as a stripe across the pan.
  4. Leave alternating gaps between strawberry rows so the white frosting shows through. Aim for even spacing between rows for a clear red-white-blue flag look.
Chill, cut, and serve
  1. Refrigerate for 30 minutes to set the frosting. The frosting should look firm and slice cleanly without smearing.
  2. Cut into squares and serve. Lift each piece carefully to keep the strawberry and blueberry pattern intact.

Notes

Pro tip: chill the frosting-free brownies first if your kitchen is warm—cool brownies help the frosting spread without tearing. Store covered in the refrigerator up to 4 days; freeze undecorated or decorated brownies in an airtight container up to 2 months for best texture. For a lighter option, use reduced-fat cream cheese and butter stick substitutes to keep the frosting thick while reducing saturated fat.
