Chocolate Buttercream (Cheese) Frosting

This frosting is so good, people ask if they can just take a bowl of it home and eat it with a spoon. It’s also smooth, creamy, and luscious, and makes a beautiful cake. Plus, we’ve added a few flavor touches: Cream cheese for tanginess, lots of real vanilla for depth, instant espresso powder for deep richness, and buttermilk for a little bite.
