Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the almond flour, baking powder, and cocoa powder. Stir until well blended.
Cream together the softened butter and granulated erythritol until light and fluffy.
Add the medium egg to the butter mixture and mix until fully incorporated.
Gradually add the dry ingredients to the wet mixture, stirring until a thick, slightly sticky dough forms.
Fold in the sugar-free chocolate chips until evenly distributed.
Drop dollops of dough onto a lined baking sheet, spacing them about 2 inches apart.
Bake for about 10-12 minutes, or until the edges are firm and the tops look set.
Allow to cool on the baking sheet for a few minutes before transferring to a wire rack.
