Method
Step-by-Step
- Heat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Beat the softened butter and granulated sugar for 2–3 minutes, until light and creamy. Beat in the egg and vanilla extract.
- Whisk the flour, baking powder, and salt in a separate bowl. Gradually mix the dry ingredients into the butter mixture just until a soft dough forms.
- Divide the dough into three equal portions. Leave one plain, tint one red with gel food coloring, and tint the last portion blue.
- For swirled cookies, roll small pieces of each color into ropes, place them side by side, twist gently, and roll or coil each bundle into a ball. Flatten the balls slightly.
- Chill the shaped dough for 30–60 minutes, especially if the butter became very soft during mixing or shaping.
- Bake for 8–10 minutes per tray, until the edges are set and the cookies remain pale. Cool on the baking sheet for about 5 minutes, then transfer to a wire rack.
- For optional icing, whisk the powdered sugar, milk or cream, and vanilla together. Drizzle or spread it over cooled cookies and add red, white, and blue sprinkles.
Notes
Use gel food coloring for strong color without extra liquid. Do not overbake; remove the cookies while the centers still look slightly soft so they finish setting as they cool. Store cooled cookies in an airtight container.
