In a large mixing bowl, combine rolled oats, cocoa powder, protein powder, chia seeds, and a pinch of salt. Stir thoroughly with a whisk.

Fold in the natural peanut butter and maple syrup to the dry mixture. Use a spatula to combine until a thick dough forms.

Shape the dough into small, bite-sized balls, about the size of a tablespoon, packing them tightly.

Arrange the bites on a parchment-lined tray and refrigerate for at least 30 minutes to set.

Once chilled, store the bites in an airtight container in the refrigerator for up to one week or freeze for up to three months.
