Mom's Caramel Icing
Growing up, this icing poured over a slice of warm cake was one of my very favorite treats. It was always a challenge to stop at just one piece. My mom made this icing for us often, and it quickly became my most‑requested birthday dessert.
My dad loved caramel icing just as much, and he has a story from his college days at Mississippi State University that still makes me laugh. Back then, dorms were pretty bare‑bones — this was the mid‑1950s, after all. One weekend, his roommate returned from home with a sheet cake covered in caramel icing. The two of them decided to save it for later in the week, imagining how good it would taste after classes and cafeteria food.
When they finally sliced into it, the knife went straight through as if there were no cake at all. A little more investigating revealed the culprit: a tiny mouse had eaten its way inside and devoured every bit of the cake, leaving only the caramel shell behind. Needless to say, both boys were more than a little disappointed.
I hope you enjoy this icing as much as we always have. It’s wonderful on Nana’s Silver Cake or any cake you love — rich, nostalgic, and so indulgent.
Mom’s Caramel Icing
There is nothing quite like traditional, homemade caramel icing to transform a simple cake into something truly memorable. Rich, buttery, and cooked to soft-ball perfection in a heavy skillet, this old-fashioned recipe delivers an authentic caramel flavor that store-bought frostings just can’t touch.
Recipe Overview

Servings: 20
-
Prep/Cook Time: 20 minutes
-
Calories: 160 kcal per serving
Ingredients
-
2 cups granulated sugar (divided)
-
1 stick (½ cup) butter, softened
-
½ pint (1 cup) heavy whipping cream, at room temperature
Instructions
-
Caramelize the Base: Take $\frac{1}{2}$ cup of the sugar and add it to a heavy cast iron skillet (or heavy-bottomed saucepan). Heat over low to medium-low heat, stirring occasionally, until the sugar slowly melts into a smooth, brown, runny liquid.
-
Combine Remaining Ingredients: Stir in the remaining $1\frac{1}{2}$ cups of sugar along with the softened butter. Pour in the room-temperature whipping cream.
-
Cook to Soft-Ball Stage: Stir constantly over medium heat until the mixture comes together and reaches the soft-ball stage on a candy thermometer ($235^\circ\text{F} - 245^\circ\text{F}$).
-
Whip to Perfection: Remove the mixture from the heat and carefully transfer it to the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed until the icing cools slightly and becomes smooth, thick, and creamy. Spread onto your favorite cooled cake immediately before it sets!
Baker’s Notes
-
Butter vs. Margarine: The traditional family recipe originally called for margarine, but swapping in real butter elevates the depth of flavor significantly and gives the icing a smooth, silky finish.
-
Temperature Matters: Make sure your whipping cream is truly at room temperature before adding it to the skillet to prevent hot caramel splatters and premature cooling.
