Spoon a small amount of yogurt into each popsicle mold. Add a layer of fruit or fruit puree.Continue alternating yogurt and fruit until the molds are almost full. If desired, use a skewer or butter knife to gently swirl the layers.
Sprinkle granola into the top of each popsicle mold. Gently press it into the yogurt so it sticks after freezing. Insert popsicle sticks and freeze for at least 4–6 hours, or until completely solid.
Run the outside of the popsicle mold under warm water for a few seconds to release the popsicles. Serve immediately.
