Prepare the Dough

1. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
2. In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
3. Add the egg, vanilla extract, and almond extract (if using), and mix until fully combined.
4. Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms.

Step 2: Divide and Color the Dough

1. Divide the dough evenly into three portions.
2. Leave one portion plain for the white layer.
3. Add red food coloring to the second portion and green food coloring to the third. Knead each portion until the color is fully blended.

Step 3: Roll Out the Dough

1. Roll each portion of dough into a rectangle about 1/4-inch thick, using parchment paper to prevent sticking.
2. Layer the rectangles on top of one another, starting with the white dough, followed by red, and finally green.
3. Gently press the layers together and roll the dough into a tight log.

Step 4: Chill the Dough

1. Wrap the dough log tightly in plastic wrap and refrigerate for at least 2 hours, or until firm.

Step 5: Slice and Bake

1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. Unwrap the chilled dough log and slice it into 1/4-inch thick rounds.
3. Place the cookies about 2 inches apart on the prepared baking sheets.
4. Bake for 8–10 minutes, or until the edges are just beginning to turn golden.

Step 6: Cool and Serve

1. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
2. Serve and enjoy your festive Christmas Pinwheel Cookies!
