In a large mixing bowl, combine the rolled oats, nut butter, and honey (or maple syrup). Stir until all ingredients are well incorporated.
Add the vanilla protein powder, ground cinnamon, and salt to the mixture. If you’re using chia seeds, add them at this stage as well. Mix until the dry ingredients are evenly distributed.
Pour in the vanilla extract and continue to mix until a dough-like consistency forms.
If using, fold in the mini chocolate chips for an added delightful surprise.
Use your hands to form small balls (about 1 inch in diameter) from the mixture, rolling them gently between your palms.
Place the protein balls on a baking sheet lined with parchment paper.
Once all the mixture is rolled into balls, refrigerate the tray for at least 30 minutes to allow the protein balls to firm up.
After chilling, transfer the protein balls to an airtight container for storage. Enjoy them as a quick snack or post-workout boost!
