Preheat oven to 350 degrees and prepare baking sheet with parchment paper.
First, strain the pumpkin through fine cheesecloth to remove excess water.
Brown the butter on the stovetop, being attentive to avoid burning it. This process usually takes less than 10 minutes. The butter will become slightly foamy just before reaching the perfect stage. Let it cool slightly before using.
Cream the browned butter with both sugars.
Add eggs, strained pumpkin puree, and vanilla extract.
Then, sift in the dry ingredients (flour, baking soda, salt, and pumpkin spice).
Add in chocolate chips.
Using a tablespoon-sized cookie scoop, shape your cookies and place them on a baking sheet.
Bake for 8-12 minutes at 350 degrees.
Cool on wire rack or serve warm.
Notes
Browning the butter isn't a necessary step but it does add an extra richness.
