1. 1. Combine the dry ingredients: In a large mixing bowl, add the rolled oats, protein powder, ground flaxseed, and a pinch of salt. Use a spoon or whisk to thoroughly combine these ingredients, ensuring the protein powder is evenly distributed. This prevents any pockets of unmixed powder later on.

2. 2. Add the wet ingredients: Pour in the natural peanut butter, honey (or maple syrup), and vanilla extract into the bowl with the dry ingredients.

3. 3. Mix until well combined: Using a sturdy spoon or your hands, mix all the ingredients together. Continue mixing until a thick, uniform dough forms. It should be sticky enough to hold together when pressed, but not overly wet. If it seems too dry, add a tiny bit more honey or peanut butter. If too wet, add a sprinkle of oats.

4. 4. Stir in chocolate chips (optional): If you’re using mini chocolate chips, fold them into the dough now. Make sure they are evenly distributed throughout the mixture.

5. 5. Form the energy balls: Take small portions of the dough, about 1 to 1.5 tablespoons each, and roll them between your palms to form compact, bite-sized balls. Aim for a consistent size so they chill evenly.

6. 6. Chill for firmness: Arrange the formed energy balls on a plate or baking sheet lined with parchment paper. Place them in the refrigerator for at least 20 minutes. This chilling time is crucial as it helps the balls firm up and hold their shape better, making them less sticky and easier to handle.
