I've made frozen treats with Greek yogurt and always found them to be a tiny bit too tart. Sour cream kept popping in my head as an alternative that could work. I'm happy to tell you - it does!
Cherry Chocolate Chip Sour Cream Popsicles
(my very own experiment, makes 7 in my small molds)
2/3c full fat sour cream
1/2c unsweetened almond & coconut milk blend
2tsp homemade vanilla
16 drops vanilla stevia
15 frozen dark sweet cherries, quartered
3T chopped dark chocolate
Mix all. Pour into molds. Freeze. Eat. Yum.
