Ingredients:
- 3 cups (360g) All-purpose flour
- 1 teaspoon (4g) Baking powder
- ½ teaspoon (3g) Salt
- 1 cup (226g, 2 sticks) Unsalted butter, softened
- 1 cup (200g) Granulated sugar
- 1 Large egg (50g)
- 1 teaspoon (5ml) Vanilla extract
- 4 cups (480g) Powdered sugar
- 3 tablespoons (24g) Meringue powder
- ½ cup (120ml) Warm water, plus more as needed
- Gel food coloring: Red, blue
- Patriotic sprinkles (red, white, and blue)
Instructions:
- Whisk together flour, baking powder, and salt. Cream butter and sugar until light and fluffy. Beat in egg and vanilla. Gradually add dry ingredients until combined.
- Flatten the dough into a disc, wrap in plastic wrap, and chill in the refrigerator for at least 1 hour.
- Preheat oven to 375°F (190°C). Roll out chilled dough to about ¼ inch (6mm) thickness on a lightly floured surface. Cut out cookies using your favorite cookie cutters.
- Place cookies on prepared baking sheets, leaving space between each. Bake for 8-12 minutes, or until the edges are lightly golden brown.
- Let cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
- In a large bowl, combine powdered sugar and meringue powder. Gradually add warm water, beating until smooth and glossy.
- Divide the icing into three bowls. Tint one bowl red, one blue, and leave one white. Add water, one teaspoon at a time, to each bowl until you have a piping consistency.
- Transfer icing to piping bags or squeeze bottles. Outline and flood cookies with desired colors. Add sprinkles before the icing sets.
- Allow the decorated cookies to sit uncovered until the icing is completely dry and hardened (at least 1-2 hours, or overnight).
