Caramel frosting on a chocolate cake has always been my mother-in-law’s preferred birthday dessert. Caramel frosting on a spice cake has long been my dad’s favorite treat. So, over the years, I have had many occasions to try various recipes, and this recipe for caramel frosting always brings rave reviews. It’s the only one I make any more.
Do not let the words “candy thermometer” scare you off.ย For years, I avoided recipes that required this tool, only to find it is so easy to use and makes for a perfect finished product. If you don’t have a candy thermometer, the baking aisle of your grocery store probably carries an inexpensive one. You will want a thermometer that clips onto the side of the pan.

Best Ever Caramel Frosting
Ingredients
- 2 cups (400g) light brown sugar
- 1 cup (240ml) heavy cream
- 3 tablespoons (42g) butter
- 1 teaspoon vanilla
- 1ยฝ tablespoons rum (optional)
Instructions
- In a heavy saucepan, cook the sugar and cream over medium heat until the mixture begins to simmer. Cover, reduce heat to low, and simmer for 2 minutes. Uncover and cook, stirring occasionally, until the temperature on the candy thermometer reaches 238โ. (After uncovering the pot, you may need to raise the heat to medium-low towards medium, depending on your stove, to maintain a simmer.)
- Remove from the heat and drop the butter on top, but do not stir. Let sit for about an hour or until mixture is approximately 110โ. Add vanilla and rum. Beat until frosting reaches a spreadable consistency. (If the frosting does not thicken, chill briefly and beat again. If you lost track of time - as I have many times - and the frosting has chilled too much, warm slightly and beat again.)
- Store in a container until ready to use, placing plastic wrap directly against surface. Keep at room temperature for up to 1 week or in the refrigerator for up to 3 weeks. If refrigerated, bring to room temperature and stir prior to frosting your cake.
