01 - Preheat oven to 350°F (175°C). Arrange pecan halves on a baking sheet and toast for 7–8 minutes, until aromatic. Cool slightly.
02 - Transfer toasted pecans and sea salt to a food processor. Process, scraping down sides as necessary, until smooth and creamy, about 3–5 minutes. Reserve 1/2 cup for dough.
03 - In a medium mixing bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, nutmeg, cloves, and ginger until evenly blended.
04 - In a large bowl, beat softened butter, pecan butter, brown sugar, and granulated sugar until light and fluffy, about 2–3 minutes using an electric mixer.
05 - Mix in pumpkin puree, egg, and vanilla extract until completely combined.
06 - Gradually add dry ingredients to wet mixture, stirring just until incorporated to avoid overmixing.
07 - Using a spatula, gently fold chocolate chips into the dough.
08 - Line two baking sheets with parchment paper. Drop heaping tablespoons (about 1.5 tablespoons per cookie) of dough onto sheets, leaving a 2-inch gap between portions.
09 - Bake in preheated oven for 13–15 minutes, until cookies are set and lightly golden at the edges.
10 - Allow cookies to cool on baking sheet for 5 minutes, then transfer to a wire cooling rack to cool completely.
