Add the rolled oats, vanilla protein powder, ground flaxseed, cinnamon, and salt to a large mixing bowl. Stir to combine.
Add the peanut butter, honey, and vanilla extract. Stir until a thick, slightly sticky dough forms.
If the mixture is too dry, add milk 1 teaspoon at a time until the dough holds together when rolled.
Scoop approximately 1 tablespoon of the mixture and roll it between your palms to form a ball.
Repeat with the remaining mixture to make approximately 16 protein balls.
Arrange the balls on the prepared baking sheet.
Refrigerate for 30 minutes, or until firm.
Transfer the protein balls to an airtight container and keep refrigerated until ready to serve.

Tips and Tricks
Use Creamy Peanut Butter – Regular creamy peanut butter makes mixing easier. Natural peanut butter works too, as long as it's thoroughly stirred.Check the Texture – The dough should feel slightly sticky and hold its shape when pressed together. Different protein powders can change how much moisture you need.Prevent Sticky Hands – Lightly dampen your hands with water if the mixture sticks while rolling.Keep Portions Even – A small cookie scoop helps make evenly sized protein balls for consistent servings.
Storing and Reheating
Refrigerator – Store in an airtight container in the refrigerator for up to 5 days.Freezer – Freeze in a freezer-safe container or bag for up to 3 months. Separate layers with parchment paper to prevent sticking.Thawing – Thaw frozen protein balls in the refrigerator overnight, or allow them to soften briefly before eating.Reheating – No reheating needed! These protein balls are meant to be enjoyed cold or at a cool room temperature.
