We're lifelong fans of buttercream and cream cheese frosting, but this mascarpone icing recipe has earned its spot as another confectionary favorite.Mascarpone is an Italian cream cheese made with whole cream and an acidic element like citric acid or lemon juice. Mascarpone is amazing in savory recipes, like pastas or salads, and sweet recipes, like cakes and traditionally, tiramisu. This mascarpone frosting recipe is creamy and smooth, and like a cream cheese frosting, it will pair well with almost any cake or cupcake recipe. With just four ingredients and no cooking, you get the most luscious frosting you've ever seen. We top our Apple-Pecan-Carrot Cake with this dreamy mascarpone frosting (plus an indulgent Caramel Sauce that's drizzled over the frosting), but this recipe is so versatile that you can use it any time you need a beautiful frosting recipe. You might think your loyalty to cream cheese and buttercream frostings will never waver, but one bite of this mascarpone frosting, and you'll be sold.
