Salted Caramel Buttercream Frosting is the decadent, sweet-salty crown your baked treats deserve. Silky smooth with rich caramel flavor and a hint of sea salt, this frosting pairs beautifully with everything from chocolate cupcakes to apple spice cakes. Whether you’re frosting a birthday cake or simply dressing up cookies, this buttercream delivers an elevated, bakery-quality touch with surprisingly little effort.

Its flavor is deeply comforting and undeniably indulgent, thanks to homemade caramel that’s whipped into a creamy butter base. The salt balances the sweetness, making every bite more addictive than the last. Once you try this frosting, you’ll be searching for new excuses to use it.

What Kind of Caramel Should I Use?

For best results, use homemade caramel sauce. It only takes a few minutes to make and gives you full control over flavor and thickness. Store-bought caramel can work in a pinch, but choose one that is thick, not syrupy, and avoid caramel toppings made for ice cream as they often lack depth and body.

Ingredients for the Salted Caramel Buttercream Frosting

1 cup (2 sticks) unsalted butter, softened
1/2 cup homemade caramel sauce, cooled to room temperature
3-4 cups powdered sugar, sifted
1/2 teaspoon fine sea salt
1 teaspoon vanilla extract
1-2 tablespoons heavy cream or milk (optional, for texture adjustment)

How To Make the Salted Caramel Buttercream Frosting

Step 1: Cream the Butter

Using a stand mixer or handheld mixer, beat the softened butter on medium speed for about 3–4 minutes, until light and fluffy.

Step 2: Add the Caramel

Gradually add the cooled caramel sauce to the butter and mix on medium speed until fully incorporated.

Step 3: Incorporate Powdered Sugar

Add powdered sugar one cup at a time, mixing on low to start, then increasing to medium. Continue until desired sweetness and stiffness is reached (3 cups for soft, 4 for firmer).

Step 4: Add Vanilla and Salt

Add in the vanilla extract and sea salt. Mix to combine.

Step 5: Adjust Texture

If the frosting is too thick, add 1 tablespoon of cream or milk at a time until the consistency is smooth and spreadable.

Serving and Storing Salted Caramel Buttercream Frosting

This frosting is a show-stopper on cupcakes, layer cakes, sandwich cookies, or even as a dip for apple slices. Once prepared, it can be used immediately or stored.

Refrigerate in an airtight container for up to 1 week, or freeze for up to 2 months. Bring to room temperature and re-whip before using to restore its airy texture.

Frequently Asked Questions

Can I use store-bought caramel?

Yes, but make sure it’s thick and rich—not syrupy. Look for high-quality brands with minimal ingredients.

Can this be piped?

Absolutely. It pipes beautifully and holds its shape, especially if you use the full 4 cups of powdered sugar.

How do I fix runny frosting?

Add more powdered sugar or chill the frosting for 15 minutes, then whip again.

Can I make it dairy-free?

You can use plant-based butter and coconut cream instead of heavy cream. Just know the texture and flavor might vary.

Is it overly sweet?

The salt and caramel balance the sweetness nicely. You can adjust the powdered sugar level to your taste.
