1-Gathering and Browning the Butter: First, brown the butter by melting 1 cup (220g) of unsalted butter over medium heat until it reaches a rich amber color. Once done, pour it into a measuring glass, scraping the brown bits, and chill for about 20 minutes without letting it solidify. This step adds a nutty depth that enhances the overall taste of the cookies.

2-Mixing Dry Ingredients: Next, preheat the oven to 350°F and line a baking sheet with parchment paper. In a medium bowl, whisk together 2 1/4 cups (280g) of all-purpose flour, 1 teaspoon baking soda, 1/2 teaspoon baking powder, 1/2 teaspoon salt, 1 1/2 teaspoons pumpkin pie spice, and 1/2 teaspoon cinnamon to ensure even distribution.

3-Combining Wet Ingredients: In a large bowl, whisk the 1 1/2 cups (280g) of packed dark brown sugar with the cooled brown butter until it becomes clumpy and wet. Add 1 large egg yolk, 3 tablespoons pure maple syrup, 1 teaspoon vanilla extract, and 1/3 cup (80g) pumpkin puree, then whisk until smooth. This mixture forms the base that gives the cookies their signature moisture and chew.

4-Final Mixing, Coating, and Baking: Fold in the dry ingredients using a rubber spatula, and if the dough is too thin, chill it for 15 to 20 minutes. In a small dish, mix the coating: 2 tablespoons brown sugar, 2 tablespoons granulated sugar, and 1 teaspoon cinnamon. Scoop the dough into about 2 oz portions (or 1/4 cup each), coat each in the sugar mixture, form into balls, and place on the baking sheet spaced 3 inches apart, baking 4-5 per batch for 12-15 minutes until edges darken and centers are puffed but slightly underdone. Let them rest on the sheet before transferring to a cooling rack and cooling completely.
