Prep: 1. Partially thaw cherries (just enough that they are blend-able) Make: 1. Combine cherries and apple juice in a blender and blend until smooth. 2. Add yogurt and blend just until combined. 3. Pour mixture into 8 ice-pop molds, insert sticks and freeze until solid, about 4 hours. 4. Dip bases of molds briefly in hot water to loosen and unmold.
You can also use small, freezable containers like 4-ounce plastic or paper cups or plastic champagne flutes as molds: Fill containers almost full and cover tops with foil, then make a small slit and insert ice-pop sticks or small bamboo skewers. If cherries are in season you can use fresh, just pit and put them in the freezer for a little before using.
