    Ingredients you Need

    • Sugar: Extra fine white granulated sugar that should be completely dissolved in the whites.
    • Butter: Softened unsalted butter, no light butter or salted butter.
    • Salted caramel sauce: Homemade or store-bought salted caramel or simple caramel made from granulated sugar, unsalted butter, heavy cream and seal salt.

    How To Make Salted Caramel Buttercream Frosting

    Here are some quick visual instructions. Don't forget that full recipe instructions with exact ingredients can be found in the recipe card below!

    Step 1: Place egg whites with the granulated sugar in a mixer bowl and cook over a double boiler on a small saucepan containing some simmering water heated over medium heat.

    Step 2: Check with a candy thermometer, the mixture should reach a temperature of 131°F/55°C, and the sugar melts. (touch the mixture to check that you can no longer smell the sugar granules)

    Step 3: Transfer the egg white mixture to the mixing bowl of your stand mixer fitted with the whisk attachment and beat on high speed for about 15 minutes until a firm meringue with stiff peaks.

    Step 4: Reduce the mixer to medium speed and add butter pieces into the Swiss meringue, then resume on high speed until a thick and smooth buttercream forms.

    Tips for this recipe

    • Cook egg whites: Use a cooking thermometer to heat the egg whites and sugar to 131°F/55°C. If you don't have a thermometer, cook for about 5 minutes until the mixture becomes foamy.
    • Use softened butter: Take the butter out of the fridge about 30 minutes beforehand and cut it into small pieces. It should be softened but not melted.
    • Whip the meringue: Beat the egg whites and sugar for at least 10 minutes until you get a firm, glossy meringue that has cooled slightly.
    • Grainy buttercream: After adding the butter, the texture may become grainy. Keep whisking until the mixture is smooth.
    • Smooth out the buttercream: Switch to the paddle attachment and mix on low speed for 2 minutes to smooth out any air bubbles in the buttercream.

    Variations & Substitutions

    • Brown Sugar Caramel Buttercream: Replace white sugar with brown sugar for a more caramelized flavor.
    • Traditional Buttercream: Follow my easy American buttercream recipe and incorporate salted caramel.
    • Italian Meringue Buttercream: A meringue-based buttercream made with sugar syrup for an ultra-shiny texture perfect with the flavor of my homemade caramel sauce.
    • Chocolate Swiss meringue Buttercream: Add cocoa powder or melted dark chocolate or white melted chocolate to the caramel buttercream for a rich chocolatey flavor like this white chocolate swiss buttercream.
    • Coffee Caramel Buttercream: Mix in a tablespoon of espresso powder or strong brewed coffee to the caramel buttercream for a delicious coffee-infused flavor.
    • Nutty Caramel Buttercream: Fold in chopped nuts like pecans or walnuts into the caramel buttercream for added crunch and nuttiness.
    • Spiced Caramel Buttercream: Add a dash of cinnamon, nutmeg, or cardamom to the caramel buttercream for a warm and aromatic flavor profile.

    Description

    Delicious salted caramel buttercream on a Swiss meringue base (to decorate 12 cupcakes or cover and decorate a 6-inch/15 cm layer cake).


    Ingredients

    • 6 Egg Whites
    • 150 g Granulated Sugar (¾ cup)
    • 300 g Unsalted Butter - softened (1 ¼ cups)
    • 2 tsp Vanilla Extract

    Instructions

    1. Place the egg whites and granulated sugar in a large heatproof bowl or in the bowl of your stand mixer.
    2. Heat the mixture over a double boiler by placing the bowl over a pot containing a little water heated over medium heat.
    3. While constantly whisking with a hand whisk, check the temperature using a candy thermometer, which should register at least 131°F/55°C (the sugar should be completely dissolved; touch with your fingertips to check that you no longer feel the sugar grains).
    4. Transfer the mixture to the bowl of your stand mixer or place the bowl back on the stand of the stand mixer fitted with the paddle attachment and beat at medium-high speed for 10-15 minutes until you get a stiff, glossy, and cooled meringue.

    6. Switch to the flat spatula attachment and gently fold in the slightly warmed salted caramel and vanilla extract until fully incorporated and the buttercream is smooth.
    7. Finish by mixing at low speed for 2 minutes to smooth out the buttercream and use it directly on your cakes.
