In a large mixing bowl, add 1 cup of creamy peanut butter, 1 cup of unsweetened protein powder, 1/3 cup of pure maple syrup, and a pinch of salt if desired. Mix until a cohesive dough forms, about 2-3 minutes.

Shape the dough into bars, roughly 2 inches wide, or press mixture into an 8x8 inch pan lined with parchment paper for uniformity.

Place the shaped bars or pressed mixture in the refrigerator and chill for about 30 minutes.

Melt 1/2 cup of chocolate chips in a microwave-safe bowl, then dip each bar into the melted chocolate or pour it over the pressed mixture, returning to the fridge until set.

Once chilled, remove from the pan if pressed, and slice into desired sizes.
