250g-650g icing sugar proportions with a dash of cream. Should I simply add less icing sugar?

Otherwise, I would use a meringue buttercream or add some cream cheese to your recipe. If you are using a standard buttercream recipe (icing sugar, butter, and a touch of milk or cream), they tend to be overly sweet.
Thank you so much!!
