What You Need To Make Caramel Frosting
- Brown sugar: melts with the half and half to create the frosting. Dark gives a more intense flavor.
- Butter and half and half: both aid in the structure of the frosting and lend flavor.
- Confectioners sugar: sift it before stirring it in so the frosting stays smooth.
How to Make Boiled Brown Sugar Frosting
This comes together in one large pot with a heavy bottom, which keeps the frosting from scorching. Everything melts down into a syrup on the stovetop, and it may take a few minutes for the syrup to start boiling. That adds a few extra minutes to the timie. The full steps are in the recipe card below.

Substitutions
Butter: if using salted butter, eliminate the salt from the recipe.
Milk substitute: whole milk can be substituted for half and half.
Sugar swap: light brown sugar can be used in place of dark brown sugar. The flavor will be a little lighter but will still be delicious.
Top Tips
- If the frosting seems to harden too quickly, add a little more half and half as needed.
- If the frosting seems to be too loose, add a little more powdered sugar as needed.
- Use a candy thermometer if you are nervous about over cooking the frosting. It should reach a temperature of 234 degrees.

Storage
Use this boiled frosting right away by pouring it over the cake you're frosting. It will harden after sitting and isn't appropriate for refrigeration unless it's already on the cake. The frosted cake can be stored in an airtight container at room temperature for up to 4 days.
