Add all ingredients to a blender and process until well combined. If using fresh fruit instead of frozen, add 4-5 ice cubes before blending.
To make popsicles: Pour blended smoothie into popsicle molds and insert a popsicle stick into the center. Freeze for 3-4 hours before removing popsicles from the molds.
Notes
Tip: Run the molds under lukewarm water for 10-15 seconds to help the popsicles loosen easily.
