- **Preheat the oven** 
- Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. 
- **Mix the dry ingredients** 
- In a medium bowl, whisk together the flour, baking soda, baking powder, salt, pumpkin pie spice, and cinnamon. Set aside. 
- **Cream the butter and sugars** 
- In a large mixing bowl, use an electric mixer to beat the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes. 
- **Add the wet ingredients** 
- Mix in the pumpkin puree, egg, and vanilla extract until well combined. 
- **Combine wet and dry ingredients** 
- Gradually add the dry ingredients to the wet ingredients, mixing just until the dough comes together. Avoid overmixing. 
- **Shape the cookies** 
- Scoop tablespoon-sized portions of dough and roll them into balls. Roll each ball in granulated sugar and place them on the prepared baking sheets, spacing them about 2 inches apart. 
- **Bake** 
- Bake for 10–12 minutes, or until the edges are set and the centers are slightly puffy. 
- **Cool and serve** 
- Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. Enjoy plain or with a sprinkle of extra cinnamon sugar on top.
