Preheat your oven to 350°F (175°C).
In a large bowl, combine pumpkin puree, brown sugar, and granulated sugar.
Add melted butter and mix well.
Beat in the egg and vanilla extract until smooth.
In a separate bowl, whisk together flour, baking soda, cinnamon, nutmeg, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold in the chocolate chips until evenly distributed.
Drop tablespoons of dough onto a lined baking sheet, spacing them about 2 inches apart.
Bake for 12-15 minutes or until the edges are lightly golden.
Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
