Easy Pumpkin Spice Cookies Recipe

Preheat oven to 375 degrees F.
Add the butter and the two sugars to the bowl of a large stand mixer. Mix the butter with the sugars until light and fluffy, approximately 2-3 minutes, scraping down sides as needed.
Mix in the eggs plus the additional yolk to the butter/sugar mixture, beating until smooth and scraping the sides as necessary. Mix in the vanilla.
In a separate bowl, whisk together the pumpkin pie spice, baking powder, salt, and flour.
Reduce mixer speed to low and carefully add the flour mixture to the butter mixture, mixing until combined and the dough has come together (the dough will be thick). Chill dough for at least an hour (I chilled mine overnight).
When ready to bake, line a large baking sheet with parchment paper and preheat oven to 375 degrees F.
Mix the light brown sugar, granulated sugar, and pumpkin pie spice together in a shallow bowl, set aside.
Roll dough into balls, about 1 1/2 inches in diameter, and then roll into the sugar/pumpkin pie spice mixture, coating completely.
Bake for 8-10 minutes, or just until cookies are lightly browned on the bottom. Remove from oven and transfer to wire rack to cool. Enjoy!
