Melt 220g of butter over medium heat, continuing to stir until it reaches a rich amber color. Pour the browned butter into a measuring glass, making sure to scrape the bottom of the pot to get all of the brown bits. Place in the refrigerator to chill for about 20 minutes, but don't let it solidify.

Preheat the oven to 180°C (350°F) and line a large baking sheet with parchment paper.

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, pumpkin pie spice, and cinnamon. Set aside.

In a large mixing bowl, whisk together the brown sugar and cooled brown butter until it resembles clumpy wet sand. Whisk in the egg yolk, maple syrup, vanilla, and pumpkin until smooth.

Add all dry ingredients to the wet mixture and fold together with a rubber spatula until fully incorporated. If the dough feels too thin (it should hold its shape when scooped), chill for 15-20 minutes until thickened.

In a small dish, mix together the brown sugar, granulated sugar, and cinnamon for coating.

Use a large cookie scoop (2oz) or 1/4 measuring cup to portion the dough. Drop each portion into the cinnamon sugar mixture and toss to coat completely.

Place coated dough balls on the baking sheet, spacing them about 8cm (3 inches) apart. Bake 4-5 cookies at a time for 12-15 minutes, until the edges are darkened and centers look puffed and slightly underdone.

Allow cookies to rest on the baking sheet for a couple minutes, then transfer to a cooling rack. Continue baking the remaining dough in batches.
