Put your room temperature butter and cream cheese in your stand mixer bowl or regular bowl if using a handheld mixer. Beat them together until you get a smooth, creamy mix with no lumps at all.

Stir in the vanilla and salt until they're fully mixed through the creamy base.

Turn your mixer to low and add the confectioners' sugar bit by bit. Keep mixing until everything looks smooth and your frosting has that perfect, fluffy texture.

Spread this frosting on your cooled cake or cupcakes. It's firm enough to make pretty designs and won't slide off.
