[header] How to make cream cheese icing [title] Choose full-fat cream cheese. [step] Avoid low-fat, whipped, or spreadable cream cheeses, as these can lead to runny frosting. This means neufchâtel cheese is out, too (you'll probably see it right next to the cream cheese), as its fat content is too low.
The fat in the butter and cream cheese are essential to stabilize the frosting and keep it from liquefying. [substeps] If you can't find full-fat cream cheese, you can try adding more butter to the recipe.
