01 - Preheat the oven to 350°F and line a baking sheet with parchment paper.
02 - In a medium bowl, whisk together the almond flour, sweetener, cinnamon, baking powder, and salt until evenly blended.
03 - In a large bowl, beat the softened butter until creamy. Add the egg and vanilla extract, mixing until fully incorporated.
04 - Gradually stir the dry ingredients into the wet mixture, mixing until a cohesive dough forms.
05 - Gently fold the chopped macadamia nuts into the dough until evenly distributed.
06 - Using a tablespoon or small cookie scoop, portion the dough onto the prepared baking sheet, spacing about 2 inches apart. Flatten each cookie slightly with your fingers or the back of a spoon.
07 - Bake for 13-15 minutes, or until the edges are golden brown and the centers are set.
08 - Let the cookies cool on the baking sheet for 10 minutes before transferring to a wire rack to finish cooling.
