These colorful popsicles can be made with red cherries only, or by alternately layering yogurt with both red and lighter colored Ranier cherries and mixing lightly with a wooden skewer.
Combine Bing cherries and 1 cup lemonade concentrate in food processor and process until smooth. Set aside.
Pour mixture into popsicle molds, alternating with spoonfuls of yogurt. Using a wooden skewer or thin knife, gently mix layers to create a swirl effect.
(If using Ranier cherries, blend 2 cups of each cherry variety with ½ cup lemonade concentrate and alternate layers with both kinds of cherries and yogurt.)
Freeze molds until firm. Unmold by briefly dipping in warm water to loosen pop.
