Old-Fashioned Chocolate Frosting

5 from 14 votes
This classic chocolate frosting is made with melted chocolate and heavy cream. A rich, fluffy alternative to standard buttercream.
Total Time 20 minutes
Servings12 (enough to generously frost a two-layer cake)

Ingredients

  • 16 ounces semisweet chocolate finely chopped (I measured 16 ounces chocolate chips on a kitchen scale, it’s a teeny bit more than 2 ½ cups.)
  • 8 tablespoons unsalted butter (1 stick)
  • cup granulated sugar
  • 2 tablespoons corn syrup
  • 2 teaspoons vanilla extract
  • ¼ teaspoons table salt
  • 1 ¼ cups cold heavy cream

Instructions

  • Melt Chocolate in heatproof bowl set over a saucepan containing 1 inch of barely simmering water, stirring occasionally until smooth. Remove from heat and set aside.
  • Meanwhile, heat butter in small saucepan over medium-low heat until melted. Increase heat to medium; add sugar, corn syrup, vanilla, and salt and stir with heatproof rubber spatula until sugar is dissolved, 4-5 minutes. Add melted chocolate, butter mixture, and cream to clean bowl of stand mixer and stir to thoroughly combine.
  • Place mixer bowl over ice bath and stir mixture constantly with rubber spatula until frosting is thick and just beginning to harden against sides of bowl, 1-2 minutes (frosting should be 70℉). Place bowl on stand mixer fitted with paddle attachment and beat on medium-high speed until frosting is light and fluffy, 1-2 minutes. Stir with rubber spatula until completely smooth.

Notes

  • Store finished frosting in the fridge in an airtight container. When ready to use, let sit at room temp for 20-30 minutes then rewhip briefly before using.
  • Don't overcook your sugar mixture! Keep the heat low and remove it from heat as soon as you don't see sugar crystals.
  • If you jumped the gun and didn't cool your frosting mixture enough, or it just seems a little too soft, pop it in the fridge for 15 minutes and whip again!
  • Note that the texture of this frosting is so light and soft, and whippy, that this frosting would probably be best for slathering- like smeared all over a cake, or just plopped on top of cupcakes, as opposed to piping.  If you’re looking for a good chocolate icing for piping- try this Chocolate Frosting!
