Preheat and Prepare Baking Sheet
Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper or a silicone baking mat.
Make the Cookie Dough
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.
Add the egg and vanilla extract, mixing until fully combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt. Gradually mix the dry ingredients into the wet ingredients until a soft dough forms.
Prepare the Cinnamon Sugar Coating
In a small bowl, combine the granulated sugar and cinnamon for the coating.
Shape and Coat the Cookies
Roll the cookie dough into 1-inch balls (about 1 tablespoon each). Roll each dough ball in the cinnamon sugar mixture until fully coated.
Place the coated dough balls onto the prepared baking sheet, spacing them about 2 inches apart.
Bake the Cookies
Bake the cookies for 10-12 minutes, or until the edges are set but the centers are still soft.
Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a cooling rack.
Serve and Enjoy
Serve warm for the ultimate churro experience or at room temperature for a soft and chewy delight!
