In a medium mixing bowl, whisk together the almond flour, protein powder, and powdered nut or seed butter until evenly combined.
Add the maple syrup, milk, vanilla extract, and sea salt. Stir until a thick, cohesive cookie dough forms.
Fold in the chocolate chips if using.
Divide the dough into 6 equal portions and roll into balls.
Chill for 10 minutes for a firmer texture, or serve immediately.
