In some countries, icing sugar is called powdered sugar or confectioners sugar. This method will make the cream cheese frosting sweeter as it is adding extra sugar to the mixture.
If you do over-mix the frosting, place it into the fridge for 1 hour to harden.
It is best to add small amounts of icing sugar at a time, as this stops the frosting from accidentally getting too thick.
If you want to use the frosting at a later date, place the airtight container into the freezer for up to 3 months. [4] X Research source
Avoid adding more than 1/2 cup (62. 5 grams) of cornstarch per 8 oz (226 grams) of cream cheese. Adding more cornstarch than this can impact the taste of the frosting. In some countries, cornstarch is called corn flour.
If the cream cheese is still too soft after 1 hour, leave it in the fridge for a further 30 minutes. If the cream cheese frosting gets too hard, simply leave it at room temperature to soften.
Purchase meringue powder from a speciality cooking or baking store. This option is really effective if you want to pipe the frosting onto a cake as it helps the mixture to hold its shape.
Continue to add soft butter to the frosting until you are satisfied with its taste and consistency. If your butter is hard, simply leave it at room temperature for 1 hour to soften.
If the mixture is still too runny, add another 2 teaspoons (5. 2 grams) of arrowroot powder.
