I may have posted this last summer, but it's just such a great idea. (from my sis-in-law, Ali).
This favorite frozen treat is simply yogurt and graham cracker crumbs. In this case I used lemon yogurt, but an flavor will do. They didn't have a large container of lemon at the store, so we bought 2 small cups and it filled these four popsicles just fine. Sometimes the best flavors only come in the individual serving sizes. I know that at Safeway here in the states, has Lucerne yogurt cups with flavor such as banana cream pie.
