The Best Caramel Buttercream Frosting Recipe

My secret to making the best caramel buttercream frosting for cake is making my own caramel! And don’t worry, it is pretty simple to make. As long as you keep an eye on it while it’s boiling you will be good to go! Here are the steps and ingredients for making the buttercream and the homemade caramel. 

To make the caramel buttercream frosting, you’ll need:

  • 2 cups (452 g) unsalted butter, slightly cold
  • 6 cups (750 g) powdered sugar, measured then sifted
  • ½ cup caramel

First, beat your butter for 3-5 minutes on medium-high speed in your electric mixer. Next, turn the speed down to medium and gradually add the caramel. Scrape down the sides of your bowl and mix again until the caramel is incorporated. 

Once the caramel is nicely mixed in, gradually add the powdered sugar while your mixer is on low speed. Then increase the speed to medium-high and beat for another 5 minutes until the buttercream is light and fluffy. 

I always recommend mixing the buttercream frosting by hand with a wooden spoon or large spatula at the very end to push out the air and create a silky-smooth frosting. 

And for the homemade caramel, you’ll need:

  • 1 cup (200 g) granulated sugar
  • ½ cup (120 g) water
  • 4 teaspoons (75 g) light corn syrup
  • ½ cup (115.5 g) heavy cream
  • 2 teaspoons (8.4 g) vanilla
  • 2 teaspoons (12 g) salt

To make the caramel, mix your sugar, water, and corn syrup in a small saucepan. Bring the water and sugar mixture to a boil over medium heat and DO NOT STIR. (Stirring encourages crystallization.) Let the mixture boil until it caramelizes into a golden brown color. It happens quickly so keep an eye on it! 

Next, remove the caramelized sugar syrup from the heat and slowly mix in the cream. Pour in just a little bit at a time, especially at the beginning. Once it is all poured in, mix to combine. Mix in your salt and vanilla and combine it all together. 

Let it cool completely before using it in your buttercream or adding it between your cake layers.

Caramel Buttercream Frosted Cake #1: Salted Caramel Gingerbread Cake with Caramel Drip

delicious caramel gingerbread cake you'll love.

This Salted Caramel Gingerbread Cake is one of my favorites for the holiday season! I am in love with the texture and flavor of this cake. It is rich in molasses and ginger but is still moist and tender. I will say this cake is slightly dense compared to a light and fluffy white cake, so just be prepared for that! I think this cake could easily become a family favorite for Christmas time!

My Mocha Caramel Oreo Cake is utterly to die for! My friends who have tried this cake (even the ones who don’t like the taste of coffee) were going nuts over it! Of course, we are adding tons of chocolate and sugar to this cake to cover up the bitter taste of coffee, so I think you’ll end up loving this one! The buttercream base is my caramel buttercream with crushed-up mocha caramel Oreos throughout it. So good!
