In a large mixing bowl, combine the peanut butter, sugar-free maple syrup, and vanilla extract until smooth.

Add the chocolate protein powder, coconut flour, and sea salt to the wet mixture.

Stir until a thick, cohesive dough forms; if the mixture is too dry, add a teaspoon of unsweetened almond milk.

Fold in the sugar-free dark chocolate chips until evenly distributed.

Scoop approximately one tablespoon of the mixture at a time and roll between palms to form 12 uniform balls.

Place the balls on a parchment-lined tray and refrigerate for at least 30 minutes to set before serving.
