In a large mixing bowl, combine the rolled oats, almond butter, chopped dried apples, honey or maple syrup, ground cinnamon, vanilla extract, and salt.
Stir the mixture well until all ingredients are thoroughly combined. If using, fold in the flaxseeds and chopped nuts for added texture and nutrition.
Once combined, the mixture should be sticky and easy to shape. If it feels too wet, add a bit more oats; if too dry, add a little more nut butter or honey.
Using your hands, roll the mixture into bite-sized balls (about 1 inch in diameter). Place them on a baking sheet lined with parchment paper.
Once all the mixture has been shaped into balls, refrigerate for about 30 minutes to firm them up.
After chilling, the energy balls are ready to enjoy!
