Method
Make the dough
- Heat the oven to 350°F.
- Line two baking sheets with parchment paper.
- Whisk the flour, cream of tartar, baking soda, cinnamon, pumpkin pie spice, and salt in a medium bowl.
- Beat the butter, granulated sugar, and brown sugar in a large bowl until light and fluffy, about 2 minutes.
- Beat in the egg yolk, pumpkin puree, and vanilla until smooth.
- Mix in the flour mixture just until no dry streaks remain.
- Cover and refrigerate the dough for 45 to 60 minutes.
Coat and bake
- Stir the sugar and cinnamon together in a small bowl.
- Roll the dough into 24 balls, about 1 1/2 tablespoons each.
- Coat each ball in the cinnamon sugar.
- Arrange the balls about 2 inches apart on the prepared sheets.
- Bake for 10 to 12 minutes, swapping and rotating the sheets halfway through, until the edges are set and the centers look puffed and soft.
- Let the cookies rest on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool.
Notes
Chill the dough for the full 45 to 60 minutes so it is easier to roll. Store the cookies in an airtight container in the refrigerator for up to 3 days; freeze for up to 2 months. For a dairy-free version, use stick-style dairy-free butter.
