How to Make It
Preheat oven to 350°F. Line 2 baking sheets with parchment paper; set aside.
With a mixer, cream together butter, brown sugar, and granulated sugar for 3 minutes, scraping down the sides of the bowl as needed. Add corn syrup and beat for an additional minute. Add vanilla and egg and beat on medium-high for 2 minutes. Add pumpkin and beat until well incorporated, about 2 minutes.
In a separate bowl, stir together flour, salt, baking powder, baking soda, and cinnamon. Add to the wet ingredients and mix on low until dough forms, about 1 minute. Fold in chocolate chips. Cover dough in plastic wrap and refrigerate for 1 hour.
Scoop out 2 tablespoon portions of dough and roll into balls before placing 2 inches apart on prepared baking sheets.
Bake until edges have slightly browned and tops begin taking on color, 18 to 20 minutes.
