Spread pumpkin puree on paper towels and blot until it seems more dry and thick (It'll be about 70g or about 1/3 cup thick paste).
1/2 cup pumpkin puree
Add the brown sugar, and granulated sugar to the cooled down brown butter and mix until smooth.
⅔ cup dark brown sugar, 2 tbsp granulated sugar
Add egg yolks, blotted pumpkin, and vanilla extract. Mix until combined.
2 large egg yolks, 2 tsp vanilla extract
In a separate bowl, whisk flour, baking soda, salt, and spices. Fold dry ingredients into wet until just combined. Avoid over mixing. Stir in chocolate chips or chunkss
1 & 3/4 cup all-purpose flour, ½ tsp baking soda, 1/2 tsp salt, 1 tsp pumpkin pie spice, 3/4 cups semisweet or dark chocolate chips/chunks
Scoop about 2 tbsp dough per cookie onto parchment-lined baking sheet.
Bake 9-10 minutes, until edges are set but centers look soft. If you want more of a wow factor, add in some extra chocolate chips or chocolate chunks to the top of your cookies as soon as they come out of the oven.
Let cookies sit on the baking sheet for 5-10 minutes before transferring to a wire rack.
