Energy balls are wonderfully versatile and easy to customize. For best results, use traditional creamy peanut butter such as Jif or Skippy, which blends smoothly and helps bind the ingredients well. Natural peanut butters can be used but may make the dough slightly less cohesive. If you or your guests have nut allergies, sunflower seed butter is a fantastic substitute that maintains both taste and texture. These bites keep well in the fridge for up to a week or can be frozen for longer storage, making them ideal for meal prep and busy schedules.
