Gluten-Free Marshmallow Frosting Recipe

This marshmallow frosting recipe was inspired by one of my favorite cookbook authors, the late Elaine Gottschall and is divine frosted over Chocolate Cake. Don’t fear if the mixture overcooks and the agave nectar turns dark amber—you will have a roasted marshmallow frosting, creating a slightly different, though equally tasty, treat.  Adapted from "The Gluten-Free Almond Flour Cookbook" by Elana Amsterdam.
