The Farmhouse Kitchen: Kicking off for a sweet summer
Make sure butter is very soft. Place in a large mixer bowl fitted with a whisk attachment. Whisk butter, cocoa powder, and half the sugar until combined; add cream and salt and whisk again to combine well. Add the rest of the sugar and whisk, increasing speed to make the frosting light and fluffy. Add vanilla. Frost cake as desired. You’ll use about half the frosting to top a sheet cake. Refrigerate leftovers.
