In a large mixing bowl, combine the rolled oats, ground flaxseed, and chocolate chips
In a separate microwave-safe bowl, heat the peanut butter and maple syrup for about 30 seconds. Stir until well combined
Add the vanilla extract and a pinch of salt to the peanut butter and maple syrup mixture and mix well
Pour the peanut butter and maple syrup mixture over the dry ingredients in the mixing bowl
Stir everything together until the mixture is well combined and forms a sticky dough
Once the mixture is ready, use your hands to roll it into small, bite-sized balls. Place the energy balls on a parchment paper-lined tray or plate
Chill the energy balls in the refrigerator for at least 30 minutes. Once they are firm, enjoy immediately or transfer the energy balls to an airtight container and store them in the refrigerator
