01 - Preheat oven to 350°F. Arrange pecan halves in a single layer on a baking sheet and toast for 7 to 8 minutes until aromatic. Allow to cool briefly.
02 - Transfer toasted pecans and 1/2 teaspoon sea salt to a food processor. Process, scraping down sides as needed, until smooth and creamy, about 3 to 5 minutes. Set aside.
03 - In a medium mixing bowl, whisk together flour, baking soda, baking powder, fine sea salt, cinnamon, nutmeg, cloves, and ginger until thoroughly combined.
04 - In a large bowl, use an electric mixer to beat softened butter, prepared toasted pecan butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, about 2 to 3 minutes.
05 - Add pumpkin puree, egg, and vanilla extract to the creamed mixture. Blend until well incorporated.
06 - Gradually introduce the dry ingredient mixture to the wet mixture, mixing gently until just combined. Avoid overmixing.
07 - Gently fold semisweet chocolate chips into the dough, ensuring even distribution.
08 - Preheat oven to 350°F if not already set. Line two baking sheets with parchment paper.
09 - Using a tablespoon measure, drop heaping spoonfuls of dough (about 1.5 tablespoons each) onto prepared sheets, spacing each about 2 inches apart. Bake for 13 to 15 minutes, until set and lightly golden at the edges.
10 - Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before serving.
