Preheat oven to 350°F (180°C). Line two baking trays with parchment paper and set aside.

Melt cold unsalted butter in a large stainless steel pan over medium heat. Stir frequently while the butter foams and crackles. Once the white milk solids settle and turn brown, and a nutty aroma develops, immediately remove from heat. Transfer browned butter (just under 1 cup) to a glass measuring bowl. Refrigerate for 50–60 minutes, stirring every 10–15 minutes, until a thermometer reads 75°F. Butter must be cool but still liquid.

Spread pumpkin puree thinly onto a plate. Use multiple layers of paper towels to press out excess moisture. Repeat until puree is dry and thick, measuring about 1/3 cup.
04 -
Whisk cooled browned butter with granulated sugar and light brown sugar for exactly 1 minute until pale and sandy in texture.
05 -
Add egg yolks, vanilla extract, and dried pumpkin puree to the butter-sugar mixture. Whisk until fully combined.

Fold in pumpkin spice, baking soda, sea salt, and chopped chocolate or chocolate chips until just incorporated.

Scoop dough using a 3-tablespoon scoop. Roll into balls and arrange on prepared baking trays, spacing 2 to 3 inches apart. For extra chocolate pools, top each dough ball with more chopped chocolate before baking.

Bake at 350°F (180°C) for 13 minutes, until edges are set and centers appear just underdone.

Allow cookies to cool on trays for 10 minutes before transferring to a wire rack. Store in an airtight container at room temperature for 2–3 days. Refrigerate or freeze uncooked dough balls if desired; bring to room temperature before baking.
