In a small stovetop pot over low heat, add the stick of butter. Let the butter melt, it will soon start to bubble and make splattering sounds. Stir occasionally, keeping your eye on the butter. As the butter stops bubbling, stir occasionally until it just starts to take on a brown color. It’s very easy to burn the butter, so keep a close eye on it. Remove from heat as soon as color starts. Pour butter into a small bowl and let cool to room temperature.

In a large bowl, add the cooled brown butter, brown sugar, and granulated sugar. Stir to combine with a spatula until light in color. Add the pumpkin puree and stir until the sugar granules have dissolved. The texture of the wet ingredients should be light and smooth.

Add the flour, baking soda, salt, and pumpkin spice to the bowl. Slowly incorporate the dry ingredients into the wet. The dough will feel dry at first, so continue to press the flour into the wet ingredients until smooth. (Sometimes I’ll use my hands here to help combine everything.)

Once the dough comes together, add the dark chocolate and stir to combine. Once the dough is combined, using a two-tablespoon scoop, scoop out 2-2 1/2 tablespoons of dough and roll into a ball. Flatten slightly between your palms and place onto a parchment-lined baking sheet. Repeat until all the dough has been scooped. Cover with plastic wrap or a parchment sheet and a kitchen towel.

Place dough into the fridge and chill for about an hour.

Preheat oven to 350 F. Line a baking sheet with parchment paper and place cookies at least 2 inches apart. You may bake in two batches to prevent crowding the pan.

Bake for 10 minutes. At the 10-minute mark, tap the baking pan onto the oven rack to de-puff the cookies. Bake for another 2 minutes, then tap again, bake another 2 minutes, then tap again, for a total bake time of 14-15 minutes.

Remove from oven and tap once more on a kitchen towel over the counter. Let cookies cool for five minutes on the pan, then transfer to a cooling rack and cool completely.

Top with salt, enjoy!
