Chocolate Cake with Whipped Ganache Frosting Recipe

chocolate cake with ganache icing and sea salt
Lauren Weisenthal

This is a decadent chocolate cake, reminiscent of Devil's Food in flavor and moisture. The whipped chocolate ganache frosting is every chocolate fiend's dream, but take care to watch it carefully: if you beat it too far, it will become chunky rather than smooth and light.

Note: I strongly recommend using a scale for all pastry projects. Serious Eats' recommended kitchen scale is the Oxo Good Grips Scale with Pull Out Display.

  • For the Cake:
  • 17.4 ounces granulated sugar
  • 12 ounces butter, softened
  • 3 large eggs, room temperature
  • 7.5 ounces whole milk
  • 3.5 ounces boiling water
  • 2.5 ounces cocoa
  • 12 ounces cake flour, sifted
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • For the Whipped Ganache:
  • 24 ounces semisweet chocolate, chopped into small pieces
  • 1 quart heavy cream
  • 1 teaspoon salt
  • Optional: sea salt for sprinkling on top


  1. For the Cake: Preheat the oven to 350°F (180°C). If using cake pans, smear a small amount of butter in the bottom of each and line the bottoms with circles of parchment. If baking on a single jelly roll pan, smear an X of butter across the center and line the bottom with parchment. Set pan(s) aside.

  2. Sift flour, baking soda, and salt together and set aside. Add boiling water to cocoa and mix, set aside to cool. In the bowl of a stand mixer fitted with a paddle attachment, cream butter and sugar together on high speed for 6-8 minutes, until very light and fluffy. Add eggs one at a time and beat well after each addition. Scrape down the sides and bottom of the bowl and the beater, and beat on high speed to ensure mixture is fully mixed. Stop mixer, add cocoa water and half the milk, plus half the dry ingredients. Mix on low until incorporated. Scrape down the mixer, then add the rest of the milk and dry ingredients. Mix thoroughly on low speed, scraping down one more time. Finish mixing with a big rubber spatula by hand, taking care not to over mix. If using cake pans, divide the batter evenly into three, if using the jelly roll pan, pour batter out and smooth evenly over the sheet.

  3. Bake layers on middle rack of oven for 10 minutes, then carefully turn them and allow them to bake for an additional 10, or until the surface springs back a bit to the touch and cake pulls away from the sides. Remove cake from oven and allow to cool in pan(s) for 10 minutes. Invert cakes and pull off parchment, allow them to cool completely. Cover with plastic wrap to prevent drying.

  4. For the Whipped Ganache: Chop chocolate very finely and place it in the bowl of a stand mixer. Bring cream and salt to a boil. Pour cream over chocolate and allow it to sit for one minute, then whisk until completely smooth (if you have a hand blender, this makes the process go faster). Chill ganache uncovered in fridge for two hours, stirring every twenty minutes. Once ganache feels cold but is still liquid, remove it from fridge and attach the bowl to the mixer. Whip using the whisk attachment, slowly at first, gradually increasing speed to high. You will notice mixture will thicken after about a minute, watch it closely. It will begin to hold soft peaks. Watch for it to get just slightly firmer, and don’t allow it to go any further. Ice cake with whipped ganache immediately after making, as it will begin to seize up if left to sit. Refrigerate cake until you are ready to serve, up to one day, allow it to come to room temperature before serving. Sprinkle with sea salt before serving if desired.
