These easy patriotic flag sugar cookies with royal icing are perfect for summer holidays and celebrations, combining a buttery sugar cookie base with vibrant red, white, and blue icing for a festive treat.
If icing is too thick, add a few drops of water; if too thin, add more powdered sugar. Chill decorated cookies after icing to help set. Use gel food coloring for vibrant colors without thinning icing. Dough can be prepared up to 3 days ahead or frozen for up to a month. Store decorated cookies in an airtight container at room temperature for up to 5 days or freeze after icing dries.
