In the mixing bowl, add flour, salt, and pumpkin spice. Sift and set aside.
In the mixing bowl of a stand mixer with the paddle attachment, beat together the butter and sugar on medium-high speed until pale and fluffy. This takes about 2 minutes.
Add flour, mix, and beat on low speed until it all forms a stiff dough. Scrape down the sides of the bowl with the spatula. Stop mixing as soon as the dough comes together.
Shape the dough into a disk about 1 inch thick and cover with plastic wrap. Place the dough in the refrigerator to chill for 30- 45 minutes.
Preheat oven to 350°F. Line two baking sheets with parchment paper or Silikomart Air Mat.
Roll the dough to 1/4 to 1/2-inch thick, rolling from the center outward in all directions. You can lift and rotate a bit after every few strokes. Dust with flour as needed to discourage sticking.
Cut out cookies using a round cookie cutter. Space the cookies about 1 inch apart on the baking sheet.
Bake cookies for 20 minutes or until they start to turn golden.
Allow the cookies to cool on the baking sheet for 10 minutes, then move them to a wire rack to cool completely.
Notes
Get all ingredients and tools ready before baking. Do not overbake cookies.
