Mix ingredients for blueberry layer, and spoon into popsicle mold cavities.
Freeze for 2-3 hours (or more).
Mix ingredients for yogurt layer, and use half of the mixture to make a white layer for the pops.
Cover the mold and insert sticks.
Freeze for 2-3 hours (or more).
Mix ingredients for strawberry layer.
Remove cover of popsicle mold. The sticks should be firmly in place.
Use half of the strawberry mix to make a red layer for the pops.
Freeze for 2-3 hours (or more).
Repeat for another white and red layer, freezing each for 2-3 hours (or more).
To remove pops from mold, immerse the mold in warm water for a minute or two. Be sure each entire popsicle is immersed in the warm water for easy removal.
Enjoy! Store extras wrapped individually in parchment paper and then in a ziplock bag.
Notes
A note about substitutions: Unflavored casein should work in this recipe (in place of the whey) but I wouldn't suggest using vegan protein powders here. They would likely have too much flavor and texture.
