Cube the butter, at room temperature and take it in a mixing bowl.

Sift in the icing sugar over the butter.

Beat this until the butter and sugar are mixed well. This will be like a fine powder as there is a lot more sugar than butter

Add in the cream cheese and beat until incorporated.

In a couple of minutes , you ll have a smooth frosting . If you rub it between your fingers, you ll feel no sugar and if you taste it, you won’t feel any grittiness. DO NOT over mix. It will not become smoother but will become too runny.
