Add the softened butter, room temperature cream cheese, salt, and vanilla, to the bowl of a stand mixer fitted with the paddle attachment. Mix until smooth.
Add the cocoa powder and powdered sugar, about 2 cups at a time, mixing in between additions. Take special care to thoroughly scrape down the sides of the bowl as you go.
If your frosting is too stiff, add a bit of cream or milk to thin it down. You will want your frosting more on the thinner side for piping.
Frosting can stay at room temperature for up to 2 hours, but should be refrigerated after that.
