Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the pumpkin puree and eggs to the mixture, and mix until well combined.
In another bowl, whisk together the all-purpose flour, baking soda, baking powder, ground cinnamon, ground ginger, nutmeg, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
In a small bowl, combine the sugar and ground cinnamon for the rolling mixture.
Use a cookie scoop or tablespoon to form uniform balls of dough, then roll each ball in the cinnamon-sugar mixture until fully coated.
Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes, or until the edges are set and the cookies are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a cooling rack to cool completely.
