1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Mix Wet Ingredients: In a large bowl, beat together softened butter, brown sugar, and granulated sugar until creamy. Add the pumpkin puree, egg, and vanilla, mixing until well combined.
3. Combine Dry Ingredients: In a separate bowl, whisk together flour, oats, baking soda, cinnamon, nutmeg, and salt.
4. Combine Mixtures: Gradually add the dry mixture to the wet mixture, stirring until just combined.

6. Scoop Dough: Use a cookie scoop or tablespoon to drop dough onto the prepared baking sheet, spacing them about 2 inches apart.
7. Bake: Place the baking sheet in the preheated oven and bake for 12-15 minutes or until the edges are golden.
8. Cool: Remove from the oven and let the cookies cool on the sheet for 5 minutes before transferring them to a wire rack to cool completely.
