In a medium bowl, add the oats, cinnamon, and chocolate chips and stir to combine.
In a small bowl, add the peanut butter *(see notes below), maple syrup, vanilla extract, chia seeds and ground flax seeds. Stir until mixture is well combined.
Add your peanut butter mixture (small bowl) to the dry ingredients (medium bowl ) and stir until thoroughly combined. Use the back of a spoon to press down as you mix to incorporate all the oats with the peanut butter mixture. This takes some muscle work because of the stickiness of the peanut butter, but I promise it will mix.
Form the mixture into balls, approximately the same size. Store in an airtight container in the refrigerator.
