Rich, fudgy homemade brownies are decorated with powdered sugar, fresh blueberries, and red icing to create a festive American flag dessert that's perfect for summer celebrations.
In a large mixing bowl, whisk the melted butter with the granulated sugar and brown sugar until smooth. Add the eggs and whisk until well combined.
In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually stir the dry ingredients into the wet ingredients until just combined.
Spread the batter evenly into the prepared pan and smooth the top with a spatula.
Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow the brownies to cool completely before decorating.
In a small bowl, whisk together the powdered sugar and milk until smooth. Stir in a few drops of red food coloring until you reach the desired shade of red.
Dust the cooled brownies with powdered sugar. Pipe the red icing across each brownie to create flag stripes, then place 3 to 4 fresh blueberries in the upper left corner to resemble the stars.
Let the icing set for 10 to 15 minutes before serving.
Notes
Tips:
Let the brownies cool completely before decorating so the powdered sugar and icing stay in place.
Use fresh blueberries for the best appearance and to keep the powdered sugar from becoming wet.
A small piping bag or zip-top bag with the corner snipped off makes it easy to pipe neat, even stripes.
Storage & Make Ahead:
Store the decorated brownies in an airtight container in the refrigerator for up to 4 days.
For the freshest presentation, bake the brownies a day ahead and decorate them before serving.
Undecorated brownies can be frozen for up to 3 months; thaw completely before decorating.
