The ingredient list gives a range of powdered to add depending on how soft or thick you'd like the frosting, to slather with a spatula or pipe on. For spreading on a cake or cupcakes you can use less powdered sugar, the frosting will be soft, if you want it thick to pipe on or to create a peak at the top of spreading on desserts more powdered sugar will allow that. Add 1/4-1/2 cup more than the beginning measurement and mix well to create the consistency you will prefer to work with, If the frosting gets too thick, add a little more heavy cream and mix well.
Be sure the cream cheese is at room temperature, it doesn’t mix well when it’s cold (it will be lumpy)
Placing the butter and cream cheese on the counter for 30 minutes before you plan on mixing the frosting is what I recommend.
I use a beater blade and stand mixer, but any mixer will work.
Place the cream cheese in the bowl of a mixer and whip it until it’s smooth, then add the butter and whip that until it’s smooth.
Pour in the powdered sugar, and begin mixing on low, drizzle in the heavy cream as you increase the speed slowly as the frosting mixes.
Add in the vanilla extract.
When all the powdered sugar is combined you can whip it on high.
The frosting should be fluffy, smooth, and silky.
If you need it thicker, you can add more powdered sugar. This is helpful if you’ll be piping it on.
This is where the salt comes into consideration, you can add a little more salt to balance the sweetness.
*If you do not like salt, do not add it.
