Using a sterilized jar; add your coconut milk and kefir water. Using a wooden spoon, stir to combine. Avoid any contact with metal or stainless steel spoons as this will react badly with the probiotics naturally found in kefir.
Loosely cover with a muslin cloth and set aside for 24 hours. You'll come back to completely dairy-free kefir. Refrigerate after 24 hours.
Add your halved peaches, kefir and maple syrup to a blender and blend until completely smooth.
Pour your ingredients into popsicle molds and place in the freezer for 8 hours, preferably overnight. If you don't have any popsicle molds, feel free to add these to an ice tray or any other mold you find appropriate.
Serve and enjoy!
