Preheat the oven to 350°F. Line a baking sheet with parchment paper. Set aside.
In a large mixing bowl, whisk together the almond flour, baking soda, baking powder, and salt until well combined.
Add the softened butter. Using a fork or mixer, blend until the mixture is uniform and crumbly, with no visible streaks of butter.
Add the egg, brown sugar substitute, and vanilla extract. Mix until a smooth, cohesive dough forms.
Fold in the chocolate chips until evenly distributed.
For chewier cookies and less spreading, cover the bowl and chill the dough in the refrigerator for 20–30 minutes. This step is optional but recommended.
Divide the dough into 24 mounds using a medium cookie scoop. Place them on the prepared baking sheet about 2 inches apart. Flatten lightly with your fingertips or the back of a fork for an even thickness, or leave them rounded for domed cookies.
Bake for 10-13 minutes, or until the edges look golden and set, and the centers appear just slightly underbaked. The cookies will firm up as they cool. For a chewier cookie, aim for the shorter baking time and pull them out when the centers are still a bit soft.
Remove from oven and let the cookies cool on the pan for 5 minutes to set. Transfer to a wire rack and cool completely before serving.
