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 using an electric mixer or whisk.
Add the pumpkin puree, egg, and vanilla extract to the mixture and blend until well combined.
In another bowl, whisk together the flour, baking soda, baking powder, ground cinnamon, nutmeg, ginger, and salt.
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix.
In a small bowl, mix together the ¼ cup granulated sugar and 2 teaspoons ground cinnamon for coating.
Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheet about 2 inches apart. Roll each ball in the cinnamon-sugar mixture before placing it on the sheet.
Bake for 10-12 minutes, or until the edges are lightly golden. The centers will look slightly underbaked but will firm up as they cool.
Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a cooling rack.
