Hi Bold Bakers!

WHY YOU’LL LOVE THIS RECIPE: My Salted Caramel Buttercream Frosting is foolproof every time, giving you a professional-style finish right at home. With just six ingredients and my expert tips for effortless caramel, this indulgent, airy frosting spreads and pipes beautifully, balances sweet, salty, and smoky notes, and transforms any dessert into a showstopper.

  • Simple & Reliable: Perfect results even if you’ve never made caramel before.
  • Bakery-Quality at Home: Achieve a professional texture and look without extra equipment.
  • Versatile & Impressive: Ideal for cakes, cupcakes, cookies, or any dessert needing a finishing touch.

Bakers often tell me that their buttercream ends up too sweet or heavy, almost like sweetened butter. My tricks from over 20 years of experience help prevent this: whip the butter thoroughly before adding any sugar, always sift your powdered sugar, and once all ingredients are combined, whip the mixture on high speed for two minutes. Aerating the frosting this way creates a light, fluffy, and perfectly smooth texture that elevates every dessert.

Salted caramel hits the perfect spot, bringing together sweetness, salt, richness, and a slight smokiness. That’s why Bigger Bolder Bakers always want more of it!

What is Salted Caramel Buttercream Frosting?

Salted Caramel Buttercream Frosting is a rich, creamy mixture of butter and powdered sugar whipped together with homemade salted caramel. The caramel gives it a slightly less sweet, more nuanced flavor than traditional vanilla buttercream.

Buttercream vs. Frosting:

  • Buttercream is a specific type of frosting made mainly from butter and sugar, whipped until light, smooth, and airy. It’s ideal for spreading, piping decorations, or layering cakes.
  • Frosting is a broader term for any sweet topping on desserts, including buttercream, whipped cream, glaze, or fondant. All buttercreams are frostings, but not all frostings are buttercreams.

American buttercream is a simplified, quick version of European buttercream, often made without meringue, and became popular in the mid-20th century for easy and versatile cake decorating. Adding homemade caramel sauce brings depth, sweetness, and a subtle smoky note that elevates any dessert.

Tools You Need

Key Ingredients and Why

Salted Caramel Frosting ingredients

  • Granulated sugar

    • Cooked granulated sugar is the base of caramel
    • As the sugar caramelizes, its flavor changes from sharply sugary-sweet to a more profound, intense sweetness like butterscotch or toffee, and it transforms from a white solid to an amber-colored syrup.
    • Check out my troubleshooting guide, How to Make Caramel (Troubleshooting Guide and Video), for detailed pro tips to set you up for success.
  • Heavy whipping cream

    • Heavy cream (FRESH CREAM with a fat content of around 36%) enriches the sauce.
    • The cream’s high-fat content contributes to caramel’s velvety texture, enhances flavor complexity, and stabilizes caramel without curdling.
    • The cream needs to be hot in this recipe. Heat it on the stovetop on low, or heat in the microwave in 30-second increments.
    • Note that milk will not work.
  • Salt

    • It’s just a half-teaspoon, but the salt takes this buttercream from purely sweet to addictively nuanced.
    • Some recipes call for sea salt, but you can use regular salt here.
  • Butter

    • Butter is the foundation of the frosting’s luxurious texture and taste.
    • Butter has to be softened correctly to get the right consistency for frosting. You know your butter is at the right temperature when you push it, and your finger makes an indent, but it doesn’t easily squish right through.
    • I prefer salted over unsalted butter here for extra flavor.
  • Powdered sugar

    • Powdered sugar (confectioners or icing sugar) sweetens frosting and gives it a smooth consistency gives it a smooth consistency to frost cakes and use in a piping bag.
    • Powdered sugar rubs against fat from softened butter during creaming, creating air pockets to incorporate air. Meanwhile, icing sugar also coats air pockets to prevent them from drying out, retaining air to stabilize frosting.
    • Always sieve the powdered sugar to remove lumps and make the frosting fluffier.

How to Make Salted Caramel Buttercream Frosting

To Make the Salted Caramel Sauce

  1. Combine sugar and water: In a medium, heavy-bottomed saucepan, stir the granulated sugar and water together over medium-low heat until the sugar has dissolved.
  2. Simmer without stirring: Once the mixture comes to a simmer, stop stirring and watch carefully.
  3. Caramelize the sugar: When the sugar turns a deep amber and starts to smell slightly smoky, turn off the heat and immediately whisk in the warm cream and salt. Be careful—caramel will bubble and steam.
  4. Smooth the caramel: Once bubbling stops, return to low heat and whisk until smooth. Transfer to a heatproof bowl and let cool completely, about 30 minutes, until it has a spreadable consistency.

To Make the Buttercream

  1. Whip the butter: In the bowl of a stand mixer fitted with a whisk attachment (or with a handheld mixer with a large mixing bowl), whip the softened butter on high speed for about 5 minutes until light and fluffy.

Gemma’s Pro Chef Tips

  • Watch the sugar carefully: Keep a close eye as it caramelizes. You want a dark, rich color for flavor, but be careful not to burn it—it’s literally a matter of seconds.
  • Have the cream ready: Make sure your cream is hot so you can stop the cooking at the perfect moment.
  • Pour with caution: Use a high-sided pot and be very careful when adding the cream. The bubbling steam can cause burns.
  • Don’t let caramel cool too much: If it gets too solid, it can be difficult to incorporate into the butter. Go by texture rather than temperature.
  • Softened butter is key: Ensure your butter is at the right temperature—soft enough to leave an indent when pressed, but not overly soft. This helps create a smooth, airy frosting.
  • Sift powdered sugar: This removes lumps and helps make the frosting fluffier.
  • Whip for lightness: Once all ingredients are combined, whip on high for two minutes to aerate the frosting and create a light, fluffy texture.

Make Ahead and Storage Instructions

  • At room temperature: You can make the buttercream a day in advance and store it in an airtight container at room temperature for up to 24 hours. If your kitchen is warm, it’s best to refrigerate it.
  • In the refrigerator: For longer storage, keep the frosting in an airtight container in the fridge for up to one week. Allow it to come to room temperature naturally and re-whip if needed before using.
  • In the freezer: Buttercream can be frozen in an airtight container for up to eight weeks. Let it thaw at room temperature and re-whip to restore its light, fluffy texture before spreading or piping.

Using Salted Caramel Frosting

FAQs

  • Can I make this buttercream if I’ve never made caramel before?

    • Yes! Caramel making is not as complicated as you might think, and homemade is so much better than store-bought caramel sauce. This is a straightforward recipe with no need for special equipment like a candy thermometer, but you do need to follow a few simple rules:
    • Use a heavy-bottomed saucepan.
    • Unless specified in the recipe, DO NOT stir your caramel once it has started to simmer
    • Cook until you get a rich brown color, but don’t allow the caramel to smoke.
    • For a deeper dive into caramel making, check out How to Make Caramel (Troubleshooting Guide and Video).
  • How do I get really fluffy buttercream?

    • The key to the best caramel buttercream frosting is perfectly softened butter. Over-softened butter can not retain air well, which leads to a flat, runny frosting. Under-softened butter will have lumps, leading to a grainy, over-whipped, split frosting.
    • The easiest way to soften butter is to leave it out at room temperature for around three hours.
    • Whip butter (use the whisk attachment and not a paddle attachment) until light and fluffy to build a structure to hold the sugar.  Otherwise, sugar will weigh down the butter leading to a flat heavy frosting.
    • Add the powdered sugar slowly, a spoon at a time so it gets fully incorporated.
    • If you see air bubbles, run your mixer at a low speed at the end of mixing. This will help to smooth out the frosting and remove big air bubbles.

The cake is frosted with Salted Caramel Buttercream frosting on the outside and layered with it on the inside, and topped with chopped toasted peanuts. The close-up shot at the slice shows the soft cake and the creamy Salted Caramel Buttercream filling.

Ingredients

Salted Caramel

  • ¼ cup (2 fl oz/60 ml) water
  • ½ cup (4 fl oz/120 ml) heavy cream , warm
  • ½ teaspoon salt

Buttercream Frosting

Instructions

To Make the Caramel

  • In a medium, heavy bottomed saucepan, stir the granulated sugar and water together over medium-low heat until the sugar has dissolved.
  • Once the mixture comes to a simmer, stop stirring and watch carefully – once the sugar turns a deep amber and starts to smell ever so slightly smoky, turn off the heat and immediately whisk in the warm cream and salt. Be careful when doing this step as the caramel will bubble and steam.
  • Once the caramel stops bubbling, return to low heat and whisk until smooth. Transfer to a heatproof bowl and let cool completely, about 30 minutes. It should thicken and have a spreadable consistency.

To Make the Buttercream

  • In the bowl of a stand mixer fitted with a whisk attachment (or with a handheld electric mixer and large bowl) whip the butter on high speed until light and fluffy, about 5 minutes.
  • With the mixer on low speed add in the cooled caramel and mix until incorporated.
  • Gradually add in the powdered sugar, one spoonful at a time. Once the sugar is mixed in, turn the mixer up to high for another 2 minutes to fully aerate the frosting.
  • Store in an airtight container at room temperature for up to a day, or refrigerate for up to a week. You can also freeze this frosting for up to 8 weeks.

Recipe Notes

  • Watch the sugar carefully: Keep a close eye as it caramelizes. You want a dark, rich color for flavor, but be careful not to burn it—it’s literally a matter of seconds.
  • Have the cream ready: Make sure your cream is hot so you can stop the cooking at the perfect moment.
  • Pour with caution: Use a high-sided pot and be very careful when adding the cream. The bubbling steam can cause burns.
  • Don’t let caramel cool too much: If it gets too solid, it can be difficult to incorporate into the butter. Go by texture rather than temperature.
  • Softened butter is key: Ensure your butter is at the right temperature—soft enough to leave an indent when pressed, but not overly soft. This helps create a smooth, airy frosting.
  • Sift powdered sugar: This removes lumps and helps make the frosting fluffier.
  • Whip for lightness: Once all ingredients are combined, whip on high for two minutes to aerate the frosting and create a light, fluffy texture.

What do you mean by heavy, hot whipping cream? How hot does it need to be? How is this best achieved? On the hob or in a microwave. Sorry, I’ve never heard of this before.
