In a large mixing bowl, add rolled oats, coconut flakes, ground flaxseed, chocolate chips and chia seeds. Mix with a wooden spoon until well combined.
Add peanut butter, honey and vanilla extract to bowl. Mix all ingredients together until well combined.
Place mixture in the refrigerator for at least 1 hour. The mixture will get more stiff and cold, making it easier to roll.
Roll the balls into 1 inch size and store in an airtight container in the refrigerator.
