In a large mixing bowl, combine the rolled oats, peanut butter, honey, ground flaxseed, vanilla extract, and pinch of salt.

Stir the mixture thoroughly until all ingredients are well combined and form a sticky dough.

Gently fold in the mini chocolate chips to evenly distribute them throughout the mixture.

Using clean hands or a small scoop, roll the mixture into bite-sized balls, roughly 1 inch in diameter.

Place the energy balls on a parchment-lined tray or container.

Refrigerate the energy balls for at least 30 minutes to help them firm up.

Once chilled, store them in an airtight container in the refrigerator for up to one week.
