Preheat and prep: Heat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Mix dry ingredients: In a large bowl, whisk almond flour, cocoa powder, baking soda, salt, and sweetener until no lumps remain.
Add wet ingredients: Stir in melted butter, egg, and vanilla. If using coffee, add it here.
Mix until a thick dough forms. Add almond milk 1 teaspoon at a time if the dough looks crumbly.
Fold in chocolate: Gently mix in the sugar-free chocolate chips. The dough should be soft and slightly sticky but scoopable.
Scoop and shape: Use a tablespoon or small cookie scoop to portion 12–14 mounds.
Roll lightly and place on the baking sheet. Press each ball gently to about 1/2 inch thick, then press a few extra chips on top for looks.
Bake: Bake 8–10 minutes, until the edges are set and the centers still look a touch soft. They will firm up as they cool.
Cool: Let cookies cool on the sheet for 10 minutes, then move to a rack.
This helps them set and get that chewy texture.
