Combine the rolled oats, mini chocolate chips, chocolate protein powder, peanut butter, honey, and 3 teaspoons of water in a medium bowl. Stir until evenly mixed, adding a little more water only if the mixture is too dry to hold together.
Portion the mixture and roll it into balls about 1 to 1 1/2 inches wide, making sixteen in total.
Place the protein balls on a plate or tray and chill for 20 minutes so they firm up.
Serve chilled. Store leftovers covered in the refrigerator, or freeze them for longer storage.
