In a large mixing bowl, add the vanilla protein powder, chocolate chips, maple syrup, and peanut butter. Mix until the ingredients combine into a cohesive dough, which should take about 2-3 minutes.

Wet your hands lightly to prevent sticking and scoop out approximately 1-inch portions of the mixture. Roll them gently into balls, approximately 12 should be made.

Place the rolled protein balls on a parchment-lined baking sheet. Cover with plastic wrap and refrigerate for at least 30 minutes.

Transfer the Cookie Dough Protein Balls to an airtight container for storage. They can be kept in the refrigerator for up to one week or frozen for longer.
