Add the rolled oats, mini chocolate chips, chocolate protein powder, peanut butter, honey, and water to a medium mixing bowl.
Stir everything together using a wooden spoon, spatula, or large spoon.
Continue mixing until a thick dough forms.
If the mixture seems dry, add an additional teaspoon of water at a time until it holds together easily.
Scoop and roll the mixture into 1 to 1½-inch balls.
Place the protein balls on a baking sheet or large plate lined with wax paper.
Refrigerate for 20 minutes to firm up.
Transfer the chilled Chocolate Peanut Butter Protein Balls to an airtight container.
Store in the refrigerator or freezer until ready to enjoy.
