Brown the butter. For a detailed tutorial, see this post on how to brown butter. Allow brown butter to cool at room temperature for just 10-15 minutes so it’s not super hot. 3/4 cup unsalted butter, browned
Whisk the sugars into the brown butter, being sure to break up any clumps of the brown sugar.
1 cup dark brown sugar, packed, 1/4 cup granulated sugar
Then, whisk in the pumpkin, egg yolk, and vanilla.
1/3 cup 100% pumpkin puree, 1 large egg yolk, room temperature, 2 tsp. vanilla extract
In another bowl, whisk together the dry ingredients. Add in the dry ingredients and fold just until combined.
2 cups all-purpose flour, spooned and leveled, 2 tsp. pumpkin pie spice, 1 tsp. baking soda, 1/2 tsp. baking powder, 1/2 tsp. salt
Fold in about ¾ cup of the chopped chocolate.
2, 4 oz. semi-sweet chocolate bars, chopped, divided
Allow cookie dough to sit at room temperature for just about 5-10 minutes so it feels more like a cookie dough (flour will hydrate). If the dough feels overly thick, you can add a splash of whole milk.
Preheat the oven to 350°F. Line 2 baking sheets with parchment paper or silicone baking mats.
Scoop the cookie dough using a 2 Tbsp. cookie scoop, and dunk the cookie dough ball in the remaining chopped chocolate pieces so the chocolate covers the tops of the cookie dough balls. Press the chocolate pieces into the cookie slightly to be sure it sticks. You can also slightly flatten the cookie dough all so you get a good surface. Repeat with remaining cookie dough balls and place 6 cookies on a baking sheet at a time.
Bake for ~8 minutes. Cookies should look set along what edges, middle might look a little underdone, but that’s perfect. Cool on the cookie sheet just for a few minutes, then carefully transfer to wire rack to cool completely. Garnish with flaky sea salt and dig in! If your cookies feel very soft, you can pop them in the fridge and they'll firm up a little 🤗
