In a medium bowl, cream together the butter, brown sugar, and granulated sugar until smooth. Add the vanilla and pumpkin puree, whisking until combined. Set aside.
½ cup unsalted butter, ¼ cup packed brown sugar, ½ cup granulated sugar, 1 teaspoon pure vanilla extract, ¼ cup pumpkin puree
In a large bowl, sift the flour, salt, baking powder, baking soda, cinnamon, and pumpkin pie spice.
1 ½ cups all-purpose flour, ¼ teaspoon salt, ¼ teaspoon baking powder, ¼ teaspoon baking soda, 1 tablespoon pumpkin pie spice mix
Combine the wet ingredients with the dry ingredients using a spoon or spatula until a soft dough forms. Fold in the pecans. Cover and chill the dough for at least 30 minutes or up to 3 days.
Line the air fryer with parchment paper.
Scoop about 1 ½ tablespoons of dough per cookie (or use an ice cream scoop), roll into balls, and place them 3 inches apart on the tray. Slightly flatten the tops with a spoon or cup and top with more pecans.
½ cup pecans
Bake for 5 minutes, until the edges are set but the centers are still soft. They will be super chewy at this point, wait for them to get cool before trying to move them. Work in batches until done.
Serve and enjoy your pumpkin cookies.
