In a large mixing bowl, combine the natural peanut butter, honey (or maple syrup), and vanilla extract. Stir until smooth and well mixed.
Gradually mix in the rolled oats, protein powder, ground flaxseed, and sea salt. Use a spatula or your hands to combine thoroughly until a sticky dough forms.
Fold in the chocolate chips into the mixture. Ensure they're evenly distributed throughout.
Use your hands to roll the mixture into small balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
Once all the mixture has been rolled into balls, place the baking sheet in the fridge for at least 30 minutes to firm up.
After chilling, transfer the protein balls to an airtight container for storage. They can be enjoyed immediately or stored in the fridge for up to 1 week.
