01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the almond flour, gluten-free rolled oats, baking soda, fine sea salt, cocoa powder, and instant espresso powder until evenly distributed.
03 - In a large bowl, beat the softened butter with the packed light brown sugar and granulated sugar using an electric mixer until creamy and pale, about 2 minutes.
04 - Add the eggs one at a time, beating well after each addition. Blend in the pure vanilla extract.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing just until combined. Do not overmix.
06 - Gently fold in the toasted chopped pecans and dark chocolate chips until evenly dispersed throughout the dough.
07 - Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
08 - Bake for 12 to 14 minutes, or until the edges are set and the centers remain slightly soft.
09 - Let the cookies rest on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
