How to Make It
Preheat oven to 400°.
Heat butter in a medium skillet over medium heat; cook, stirring frequently, until butter is a deep brown and fragrant, about 8-10 minutes. Remove from heat and let come to room temperature.
Whisk together flour, baking soda, cinnamon, and salt in a medium bowl.
Beat together butter and sugars in a large mixing bowl with an electric mixer at medium speed, scraping down the of the bowl sides as necessary. Add pumpkin puree, vanilla, and egg and mix until combined. Fold in morsels.
Drop 2-tablespoon mounds of dough 2-inches apart onto a parchment paper-lined baking sheet (no more than 6 cookies per sheet).
Bake for 9-11 minutes or until golden brown. Cool on baking sheet for 3 minutes; transfer to wire racks to cool completely.
