Ingredients Notes

The key to this caramel frosting is a careful balance of simple ingredients that come together to create its rich, creamy texture.

Start with butter, which provides the foundation for both flavor and texture. Unsalted butter is ideal since it allows you to control the salt level in the final frosting. If you only have salted butter on hand, simply reduce the added salt slightly.

Next, you’ll need brown sugar, which gives the frosting its signature caramel flavor. Dark brown sugar will create a deeper, more molasses-like taste, while light brown sugar results in a slightly milder caramel. Either works beautifully, so choose based on your preference.

For creaminess, use heavy cream or whole milk. Heavy cream will give you the richest, smoothest frosting, while whole milk creates a slightly lighter version. If you need a dairy-free option, coconut milk can work as a substitute, adding a subtle coconut flavor to the frosting.

A splash of vanilla extract rounds out the flavor, enhancing the caramel notes and adding a hint of warmth. Be sure to use pure vanilla extract for the best results.

Finally, a pinch of salt is essential. It helps balance the sweetness and brings out the depth of the caramel flavor. Don’t skip this—it makes a big difference!

How to Make This Caramel Frosting

Making caramel frosting is easier than you might think, and once you’ve mastered the technique, you’ll want to make it again and again.

Begin by melting the butter in a medium saucepan over medium heat. Once fully melted, add the brown sugar and stir constantly. The sugar should dissolve into the butter, creating a thick, grainy mixture. Let this cook for about two minutes to deepen the caramel flavor.

Slowly pour in the heavy cream while stirring. Be careful, as the mixture may bubble up slightly. Continue stirring until the cream is fully incorporated, and the mixture becomes smooth. Let it cook for another minute, then remove the saucepan from the heat.

Now it’s time to add the vanilla extract and salt. Stir them in, and then allow the caramel mixture to cool slightly. It should still be warm but not too hot, as adding powdered sugar to a very hot mixture can cause it to become grainy.

Once slightly cooled, gradually whisk in the powdered sugar. For an ultra-smooth consistency, use a hand mixer or stand mixer on low speed. If the frosting is too thick, add a splash of milk or cream to reach your desired consistency.

Let the frosting sit for a few minutes to thicken. If it becomes too firm, you can reheat it gently or add a little more liquid to soften it. Now, it’s ready to spread over cakes, cupcakes, or even cookies!

Storage Options

If you have leftover frosting, you can store it for later use. Simply transfer it to an airtight container and keep it at room temperature for up to a day. If you need to store it longer, refrigerate it for up to a week.

When you’re ready to use refrigerated frosting, let it come to room temperature and give it a good stir. If needed, warm it slightly in the microwave in short intervals, stirring between each, until it reaches a spreadable consistency.

For longer storage, you can freeze caramel frosting. Place it in an airtight container or freezer-safe bag and freeze for up to three months. Thaw it overnight in the refrigerator, then let it sit at room temperature before using.

Variations and Substitutions

This caramel frosting is incredibly versatile, and you can easily adjust it to suit your preferences or dietary needs.

For a salted caramel version, simply increase the amount of salt slightly. A sprinkle of flaky sea salt on top of the frosted cake adds a beautiful finishing touch.

If you want a deeper caramel flavor, cook the brown sugar and butter mixture for an extra minute before adding the cream. This will intensify the toasty, almost toffee-like notes.

To make a dairy-free version, swap the butter for a plant-based alternative and use coconut milk instead of heavy cream. The result will have a slightly different flavor but still be deliciously creamy.

For a thinner, pourable caramel glaze, reduce the amount of powdered sugar and add a little extra cream. This works wonderfully for drizzling over bundt cakes, cinnamon rolls, or even pancakes.

No matter how you customize it, this caramel frosting is sure to be a hit. So go ahead—spread it, drizzle it, or eat it by the spoonful (no judgment here).
