In a blender combine all ingredients except the pistachios and blend to fully combine. Taste test and add in more honey or matcha as desired.
(Optional, using a spoon or spatula, fold in the crushed pistachios)
Spoon into popsicle molds, leaving ¼-½ cm at the top empty as the popsicles will expand when frozen.
Set in freezer for at least 3 hours, ideally overnight.
To remove from molds, run the individual mold under lukewarm water, gently wiggling the popsicle stick until it comes free. Don’t get any water on the popsicle itself – just the mold. Enjoy!
