Two-Ingredient Frosting as Creamy as the Canned Stuff—With Far More Flavor

Take what you think you know about making frosting and forget it (for now). The frosting we have here is different, for a few reasons:

  1. It's called sweet potato frosting.
  2. There are just two (!) ingredients.
  3. One of these ingredients is sweet potato purée (!!).
  4. The other ingredient is semisweet or bittersweet chocolate (!!!).

It looks like this:

The frosting, from Better Baking by Genevieve Ko, is as simple to make as the ingredient list suggests. Simply bring the sweet potato purée to a simmer in a large saucepan, remove from heat, add the dark chocolate, and stir until smooth. Let it cool, stirring occasionally, until the frosting is at room temperature and the same consistency of canned frosting (but so, so much better). And, look! You can watch how to make it.

If you go to the recipe, you'll see this frosting is meant to accompany a chocolate-zucchini cake. And while you could spread it over the cake, "creating swoops and swirls," as Ko suggests, the two-ingredient frosting is no one-cake wonder: Use it in place of any other (far more complicated) frostings, swap it out for a glaze, or dollop it on top of a slice of poundcake or similar loaf-like things. Here are some ideas to get you started:

Although we've yet to try it (soon!), you could swap the sweet potato purée for pumpkin or butternut squash purée and the semisweet or dark chocolate for milk chocolate. The swoops and swirls, though? Those are less optional.

I'd like to hear about the flavor. My sweetie love chocolate frosting but loathes sweet potatoes. Can this be a secret swap?

Try it with cupcakes maybe? I don't think anyone would know unless you telk them.
