• 1/2 c. chopped toasted pecans (see Note)
Preheat oven to 325 degrees and line baking sheets with parchment paper.
In the bowl of an electric mixer on medium-high speed, beat butter until creamy, about 1 minute. Reduce speed to medium-low, add 1/2 cup powdered sugar, 1/4 cup cocoa powder and vanilla extract, and mix until thoroughly combined. Reduce speed to low, add cayenne pepper, 1 teaspoon cinnamon, salt and as much of the flour as your mixer can handle, mixing until just combined. Stir in remaining flour, then stir in chocolate chips and pecans. Form dough into 1-inch balls and place 2 inches apart on prepared baking sheets. Bake 19 minutes. Remove cookies from oven and cool for 2 minutes before transferring to a wire rack to cool completely.
