Blend all the ingredients in a blender until smooth. If you're using fresh fruit, consider adding some ice to thicken your concoction just a little bit.
Pour your mixture into popsicle molds and freeze.
A little tip: When you're ready to pull the popsicles out of the molds, then just run a little hot water over the mold to loosen the popsicle. Give it a little wiggle and gentle pull. Pop! Out comes your popsicle!
