Measure out all your ingredients into a mixing bowl.

In a mixing bowl, combine the rolled oats, protein powder, and any dry mix-ins like chocolate chips or dried fruit.

Add the nut butter and honey (or maple syrup) to the dry mixture.

Pour in the vanilla extract and mix everything thoroughly.

Stir until all ingredients are fully incorporated.

With your hands, take small portions of the mixture and roll them into 1-inch balls.

Place the rolled balls on a baking sheet or plate lined with parchment paper.

Chill in the refrigerator for at least 30 minutes.

Once chilled, transfer the protein balls to an airtight container.
