Add blueberries, agave, and 1 cup of the coconut milk to a food processor or blender and puree until smooth

Pour into popsicle molds, leaving an inch or so of space at the top

Transfer remaining coconut milk to a measuring cup and slowly pour on top of the blueberry mixture

Take a butter knife and slide into each mold and swirl a little bit

Cover with lid, insert sticks into each, leaving about an inch or so out

Freeze overnight

To remove the pops, fill sink with hot water and set into water for 15 seconds, careful not to go over the top

If the popsicles don't easily slide out, dunk the mold again for another 10 - 15 seconds

Serve immediately or refreeze on a plate
