1. 1. Combine Dry Ingredients: In a large mixing bowl, thoroughly combine the rolled oats, protein powder, and chia seeds. Use a spoon or whisk to ensure everything is evenly distributed. This helps prevent clumps of protein powder in the final product.

2. 2. Add Wet Ingredients: Add the peanut butter, honey (or maple syrup), and vanilla extract to the bowl with the dry ingredients.

3. 3. Mix Until Combined: Using a sturdy spoon or a rubber spatula, mix all the ingredients together. At first, it might seem a bit dry and crumbly, but keep mixing. The warmth from your hands and the pressure of mixing will help combine everything.

4. 4. Adjust Consistency with Milk: If the mixture is too dry and won’t hold together when pressed, add milk one tablespoon at a time. Mix well after each addition until the mixture is moist enough to form into balls without crumbling. You’re looking for a dough-like consistency.

5. 5. Stir in Chocolate Chips (Optional): If using, fold in the mini chocolate chips until they are evenly distributed throughout the mixture.

6. 6. Roll the Balls: Take small portions of the mixture, about 1-1.5 tablespoons each, and roll them between your palms to form compact, bite-sized balls. Aim for a consistent size for even chilling.

7. 7. Chill to Firm Up: Place the formed protein balls on a baking sheet lined with parchment paper. Transfer the baking sheet to the refrigerator and chill for at least 30 minutes. This step is crucial for the balls to firm up and maintain their shape, making them less sticky and easier to handle.

8. 8. Serve and Enjoy: Once chilled, your no-bake oatmeal protein energy balls are ready to be enjoyed!
