In a large mixing bowl, combine old-fashioned oats, creamy peanut butter, honey, mini chocolate chips, ground cinnamon, and vanilla extract. Use a spatula to incorporate all the ingredients thoroughly, ensuring the oats are evenly coated.

If the mixture feels too dry or crumbly, add a drizzle of honey to moisten it. Stir again until the desired consistency is achieved.

Using a mini ice cream scoop or your hands, take small portions of the mixture and roll them into bite-sized balls, about 1 inch in diameter.

Place the shaped energy bites on a parchment-lined baking sheet or plate. Transfer to the refrigerator and chill for at least 30 minutes.

Once chilled and firm, transfer the energy bites to an airtight container. They can be stored in the refrigerator for up to 10 days.
