Chocolate Buttercream

  • Yield: Makes 12 cups
Chocolate Buttercream

Source: Martha Stewart Living, October 2008


  • 10 large egg whites
  • 2 1/2 cups sugar
  • 32 ounces (8 sticks) unsalted butter, softened
  • 24 ounces semisweet chocolate, melted


  1. Whisk whites and sugar in a heatproof mixer bowl until combined. Set bowl over a large saucepan of simmering water, whisking until sugar dissolves and mixture registers 160 degrees on a candy thermometer, about 5 minutes.

  2. Transfer bowl to mixer, and whisk on high speed until stiff, glossy peaks form and mixture is cool, about 10 minutes. Reduce speed to medium, and add butter, 1 tablespoon at a time, whisking until incorporated before adding more. Reduce speed to low, and whisk in chocolate. Raise speed to medium-high, and whisk until well combined. (Buttercream can be refrigerated up to 3 days or frozen for up to 1 month. Bring to room temperature before using; beat on low speed until smooth.)

    This buttercream is very rich and tasty. It ends up looking and tasting like mousse, very fluffy. My girls LOVED it. Desolving the egg whites and sugar took a lot longer that indicated to get to 160 degrees but definitely worth it. It will harden when refrigerated and took several hours before I could remix it.

    Hi If the consistency is thin you might not have beat it enough.the frist time I made this buttercream i threw the whole thing to would not get tick enough,Then I tired again and beat it longer that was the trick.As for the chocolate anything that starts out white you will have a hard time getting it darker no matter what chocolate you use.

    Buttercream taste good but the consistency is thin compare to what Im used to work with. What can I do to make it stiffer and what chocolate can I use for a deeper darker color.
