Gather all your ingredients to make the process smoother.
In a large mixing bowl, combine the rolled oats, chocolate protein powder, and cinnamon. Stir until well mixed.
In a separate bowl, mix together the natural peanut butter, honey, and vanilla extract until smooth.
Pour the peanut butter mixture into the dry ingredients and stir until evenly combined. Fold in the mini chocolate chips, chopped nuts, and shredded coconut if using.
Form the mixture into small balls, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
Refrigerate the baking sheet for at least 30 minutes to help the bites firm up.
