In a large mixing bowl, combine old-fashioned oats, creamy peanut butter, honey, mini chocolate chips, ground cinnamon, and vanilla extract. Mix until well combined, about 2-3 minutes.

Scoop out the mixture using a mini ice cream scoop or your hands. Roll into bite-sized balls and arrange on a parchment-lined baking sheet.

Place the baking sheet in the refrigerator and chill for approximately 30 minutes to firm up.

Once chilled, transfer the energy bites to an airtight container. They can be stored in the refrigerator for up to 10 days or frozen for longer storage.
