Genevieve Ko's School Party Sheet Cake is topped with an unbelievably delicious two-ingredient frosting.

We tested the healthy, two-ingredient frosting everyone is talking about. Get ready for your baking world to be rocked.

Those of you who already have Genevieve Ko’s popular new(ish) book, Better Baking: Wholesome Ingredients, Delicious Desserts, know what a gem it is. At the heart of her unconventional approach is swapping many standard baking ingredients with natural, better-for-you options. The results are still indulgent and delicious, but legitimately healthier, making you wonder if Ko is either crazy or a genius. I vote genius. Take, for example, the two-ingredient frosting that Genevieve spreads on her School-Party Sheet Cake (scroll down; the recipe is published right on Amazon!). Her rich and creamy frosting is made with chocolate and only one other healthy -- and totally unexpected -- ingredient and contains no added sugar. As in, NONE! To squash my own skepticism -- and answer to your  raised eyebrows -- I went ahead and tested this curious two-ingredient frosting. Read on to find out what it's made of  and how it stood up to three tough critics.

Healthy, two-ingredient frosting: What's in it?

Genevieve's creamy two-ingredient frosting is made with chocolate and sweet potatoes! You just melt finely chopped bittersweet or semisweet chocolate and mix into warmed sweet potato puree. Within seconds, a decadent chocolate frosting forms right before your eyes. Just be sure to use pure, canned sweet potato puree (freshly cooked sweet potato will affect the texture) and chocolate with a cacao content between 55 and 60%.

Does this healthy, two-ingredient chocolate frosting actually work?

Well, it’s definitely the quickest frosting recipe I've ever made, and quite probably the healthiest. I used 10 ounces of finely chopped bittersweet chocolate (60% cacao), but bittersweet and semisweet are often used interchangeably, so don't stress if you're not sure which one to buy. The frosting also had a beautiful, silky texture. So far, so good.

But how does it taste?

On its own, the flavor of this frosting falls a little on the dark side, with some bitter notes -- which I love. But what about my girls? My 5-year-old said that it tasted like chocolate chips, and although she thought it was a little dark, too, she licked the entire spoon clean (with competition from her younger sister). So I think they approve. Then, when we used it to top cake, it hit the perfect sweet spot. The girls and I agreed that given the near-magical ease of making it, the creamy dark chocolate-y flavor, and, uh, the fact that it's made with SWEET POTATO, this frosting recipe is definitely a keeper. SO I was right, Ko is a genius.

A few tips for when making your own healthy, two-ingredient chocolate frosting.

There's so little to this easy recipe that you hardly need pro tips, but just a couple of pointers should help. First, use a serrated knife to finely chop blocks of chocolate. And, once the frosting is made, keep in mind that it will solidify after it sits for a few hours, making it hard to spread. I tested re-warming it over low heat and it quickly returned to its silky state. Just be sure to stir often.
