Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.

In a small bowl, mix together the sugar and cinnamon for rolling.

In a mixing bowl, whisk together the flour, baking soda, baking powder, cinnamon, nutmeg, and salt.

In another bowl, cream together the softened butter and sugar until light and fluffy.

Add the pumpkin puree, egg, and vanilla extract, mixing until well combined.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Using a cookie scoop, drop dough onto the prepared baking sheet.

Roll each dough ball in the cinnamon-sugar mixture before placing it back on the sheet.

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.

Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
