Brown the butter
- Put the butter into a medium saucepan over medium heat. Let it melt, then continue cooking, stirring often, until it foams, smells nutty, and the milk solids at the bottom turn golden brown. This usually takes about 4 to 6 minutes.
Cool the butter slightly
- Pour the browned butter into a mixing bowl, making sure to scrape in all the browned bits. Let it cool for about 10 to 15 minutes. It should still be liquid, but not piping hot.
Blot the pumpkin
- Spread the pumpkin purée onto a plate lined with paper towels, then press gently with more paper towels to remove some of the moisture. You are not trying to dry it out completely, just take away the excess wetness that can make the cookies cakey.

Mix the dry ingredients
- In a separate bowl, whisk together the flour, cream of tartar, baking soda, salt, cinnamon and pumpkin pie spice.
Mix the wet ingredients
- Add the brown sugar and granulated sugar to the browned butter and whisk until glossy and well combined. Whisk in the blotted pumpkin purée, egg yolk and vanilla.
Bring the dough together
- Add the dry ingredients to the wet ingredients and stir until no dry flour remains. The dough will be soft but should still hold its shape.
Chill the dough
- Cover and chill the dough for about 45 minutes. This helps the cookies stay thick and makes the dough easier to scoop and roll.
Prepare the coating and oven
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper. In a small bowl, mix together the sugar, cinnamon and pumpkin pie spice for the coating.
Scoop and coat
- Scoop the dough into 16 large balls, roughly 3 tablespoons each. Roll each one in the cinnamon sugar coating until well covered.

Bake
- Place the cookies on the prepared baking sheet, leaving space between them. Bake for 11 to 13 minutes, until the edges are set and the tops look puffed and lightly crackled. The centers should still look just slightly soft.
Cool
- Let the cookies sit on the baking sheet for 5 minutes, then transfer them to a cooling rack. If you like, sprinkle a tiny pinch of flaky sea salt on top while they are still warm.
