In a large mixing bowl, whisk together the almond flour, chocolate protein powder, cocoa powder, and sea salt until no lumps remain.
Add the sugar-free sweetener, melted coconut oil, and almond milk to the dry ingredients.
Stir the mixture with a spatula until a stiff, cohesive dough forms. If the mixture is too dry, add almond milk 1 teaspoon at a time.
Gently fold in the sugar-free dark chocolate chips.
Using a small cookie scoop or tablespoon, portion the dough into 12 even pieces.
Roll each portion between your palms to form a smooth ball.
Place the balls on a tray lined with parchment paper and refrigerate for at least 30 minutes to set before serving.
