2 cups plain yogurt (one cup can be vanilla if you want a little extra sweetness)
1/2 cup each: strawberries, raspberries, peaches, blueberries (frozen)
1 banana
Orange Juice (As needed. I usually add a little as I blend until it gets to a consistency I like)
Once you've got that all figured out, you'll need to find space in your freezer. This is the hardest part. They need to be fairly upright, but if you're life me and you've purchased enough frozen veggies in case Armageddon becomes a movie based on real life, you'll need to do some rearranging.
Give them a night to freeze. If they don't come out right away when you try to bust them out, warm the container a little in your hand or let them sit on the counter for five minutes or so. Then, enjoy! These can get pretty messy, so they are best enjoyed outside (or inside with a towel!)
