If you prefer a thinner icing, you can slowly add a little milk or heavy cream to the frosting until you achieve the consistency you want.
Substitutions
Butter - Unsalted. If you're using salted, you may want to use regular caramel icing.
Powdered Sugar - If you don't have any on hand, you can pulse white granulated sugar in a food processor until fine.
Salted Caramel Sauce - Make homemade salted caramel sauce or purchase a jar at your grocery store.
How to Spread Frosting
Room Temperature - This salted caramel frosting is so fluffy and creamy that it’s almost effortless to spread. It's easier to spread when it is at room temperature, so if you've made it ahead of time and kept it in the fridge, allow some time to let it warm up.
Spatula or Pipe - Use a pallet knife or spatula to spread the frosting outwards from the centre of the cake or cookie. Alternatively, you can pipe it onto cupcakes and cookies.
How To Store
Room Temperature - This frosting is stable, so can be stored at room temperature in an airtight container for 3 or 4 days.
Refrigerate - The frosting will last for up to two weeks in an airtight container in the fridge, but it's best to use within a week.
Freeze - Place it in a freezer bag and squeeze any excess air out. It will keep for up to 3 months. Thaw it in the fridge overnight before use.
