01 - Place the butter in a saucepan over medium heat. Cook, swirling occasionally, until the butter foams and turns golden brown with a nutty aroma (about 4-5 minutes). Immediately remove from heat and transfer to a mixing bowl. Allow to cool for 5 minutes.
02 - Add the sweetener to the browned butter and whisk until combined. Mix in the egg, maple extract, and vanilla extract until smooth.
03 - In a separate bowl, whisk together almond flour, coconut flour, baking soda, and salt.
04 - Fold the dry ingredients into the wet mixture until just combined. Stir in the chopped pecans.
05 - Preheat the oven to 350°F and line a baking sheet with parchment paper.
06 - Scoop heaping tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each cookie slightly with your fingers or the back of a spoon.
07 - Bake for 12-15 minutes, until the edges are golden. The centers will appear soft.
08 - Allow cookies to cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
