Preheat your oven to 300°F / 150°C.
Line two large baking sheets with parchment paper.
In a medium bowl, whisk together the dry : almond flour, cocoa powder, stevia, and salt until well combined.
In a separate large bowl, use a hand mixer to cream the room-temperature butter until smooth.
Beat in the vanilla extract and applesauce until fully incorporated.
Gradually add the dry ingredient mixture to the wet , mixing on low speed until a soft, uniform dough forms. Scrape down the sides of the bowl as needed.
Using a small cookie scoop or a tablespoon, drop rounded portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake for 30-35 minutes, or until the edges are set and the centers are firm to the touch. They will still be soft.
Let the cookies cool on the baking sheets for 10 minutes before carefully transferring them to a wire rack to cool completely. They will firm up as they cool.
