Martha Stewart Cinnamon Swirl Cookies

Instructions

1. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

2. In a large mixing bowl, cream together the butter and 1 cup of sugar until light and fluffy.

3. Add the egg and vanilla extract to the butter mixture, and mix until well combined.

4. Gradually add the dry ingredients to the wet ingredients, mixing until a smooth dough forms.

5. In a small bowl, mix together the cinnamon and 1/4 cup of sugar for the filling.

6. Roll out the dough on a floured surface into a rectangle about 1/4 inch thick.

7. Sprinkle the cinnamon-sugar mixture evenly over the dough.

8. Starting from one long edge, tightly roll up the dough into a log.

9. Wrap the dough log in plastic wrap and chill in the refrigerator for at least 1 hour.

10. Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.

11. Remove the dough from the refrigerator and slice it into 1/4-inch rounds.

12. Place the cookie rounds on the prepared baking sheet, leaving some space between them.

13. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.

14. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
