Preheat the oven to 330°F (165°C). Line a baking sheet with parchment paper. Mix the tahini, maple syrup, cocoa powder, and salt in a bowl.
Add the almond flour and baking powder, stirring until a thick cookie dough forms.
With damp hands, shape 7-8 small to medium-sized balls, place them on the prepared pan, and gently press to flatten.
Bake for 10-14 minutes, until the bottoms are lightly golden (gently lift one with a spatula to check) and the centers are still soft. Let it cool completely.
Store in an airtight container at room temperature for up to 10 days.
