Looking for a frosting with exceptional chocolate flavor that’s not too sweet? This is your recipe!
Have you ever found yourself eating a cake and thinking it would be perfect if the icing was just a bit less sweet? If so, this recipe is for you.
Originally featured alongside the Yellow Sour Cream Cake in my friend Alexis deBoschnekโs cookbook, Nights and Weekends, this chocolate frosting is versatile enough to be the finishing touch on many of your other favorite cakes as well.
The recipe is easy yet sophisticatedโthink of the richness of a dark chocolate bar over its milk chocolate counterpart. Thanks to a clever splash of buttermilk, it boasts a light, silky texture that spreads like a dream and offers an incredible depth of flavor.
Whether youโre topping a classic yellow cake, a deep dark chocolate sponge, or even just sneaking a spoonful straight from the bowl, this is the reliable, back-pocket frosting that will change how you finish your favorite cakes and cupcakes.
While buttermilk may not be your typical frosting ingredient, it worksโexceptionally well. It accomplishes the same flavor-balancing tang that cream cheese affords, but with a much lighter finish. Plus, because the recipe uses less sugar than traditional frostings, the result is light, fluffy, and richly chocolatey with exactly the right amount of sweetness. I’ve served it to kids and adults, and they’ve all raved!
