In a large mixing bowl, combine the rolled oats, protein powder, flaxseed meal or chia seeds, and a pinch of sea salt. Stir well to ensure everything is evenly distributed.

Add the peanut butter, honey or maple syrup, and vanilla extract to the dry mixture. Stir until the mixture becomes thick and well combined.

Fold in the dark chocolate chips or cacao nibs and shredded coconut if using. Mix until they are evenly distributed throughout the dough.

Using your hands, roll the mixture into small balls, about 1 inch in diameter. If the mixture is too sticky, you can slightly dampen your hands with water to make rolling easier.

Place the protein balls on a baking sheet lined with parchment paper. Chill them in the refrigerator for at least 30 minutes to set. Once firm, you can transfer them to an airtight container.

Your protein balls are ready to eat! Store them in the refrigerator for up to a week or freeze them for longer storage.
