Peanut Butter Frozen Yogurt is simple to make, you'll want to try more frozen yogurt flavors!
[My Two Cents]
If you aren't familiar with stevia, there are many articles you can find online. Basically, it's an all-natural sweetener made from a plant. But, beware, not all brands are created equal. Food Babe has a great article worth checking out if you'd like more information. We currently use the Stevita brand, however we may be making a switch to a more natural extract version.
Also, if you do end up using stevia DO NOT use more than a couple of teaspoons. It is VERY sweet. I accidentally used... a lot more than I should have the first time I made this, it's much better in small doses :)
