In a large mixing bowl, combine the rolled oats, ground flaxseed, and chia seeds (if using).

Add the peanut butter, honey or maple syrup, and vanilla extract to the dry ingredients. Mix well until the ingredients are fully combined.

Fold in the mini chocolate chips evenly throughout the mixture.

Using your hands or a spoon, scoop out small portions of the mixture and roll into bite-sized balls (approximately 1 inch in diameter).

Place the energy bites on a parchment-lined tray or plate and refrigerate for 20-30 minutes to firm up.

Store the energy bites in an airtight container in the refrigerator for up to one week or freeze for longer storage.
