Wash peaches, cut in halves and remove pits.
I didn't remove the skins, but feel free to do so if you prefer.
In a high speed blender or food processor, add peaches, cinnamon and sweetener (if using). Blend until you reach your desired consistency.
Add in chia seeds and mix by hand until well incorporated.
Keep in an airtight container in fridge. Allow to sit for at least 3 hours so chia seeds can plump up.
