Ingredients

  • 8 eggs chilled
  • 16 ounces bittersweet chocolate chopped
  • 1 cup unsalted butter cut into small cubes
  • ¼ cup brewed coffee at room temperature
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract

To Garnish

  • Powdered sugar

Instructions

  • Adjust oven rack to lower-middle position and preheat oven to 325 degrees F. Grease 8-inch springform pan, line the bottom and sides with parchment, then grease the parchment. Wrap the outside of the pan with a double layer of aluminum foil and place in a 9x13-inch pan. Put a small pot of water on to boil.
  • Using a stand mixer with a whisk attachment, beat the eggs on medium speed until doubled in volume, about 5 minutes.
  • Meanwhile, place the chocolate, butter and coffee in a large, heat-proof bowl set over a saucepan of barely simmering water. Stir occasionally until completely melted and smooth and very warm (the mixture should register 115 degrees F on an instant-read thermometer). Remove from the heat and stir in the salt and vanilla extract.
  • Using a large rubber spatula, fold one-third of the eggs into the chocolate mixture until just a few streaks of egg are visible. Add the remaining eggs in two more additions, folding until the mixture is totally combined.
  • Transfer the batter to the prepared springform pan and smooth the top. Pour enough boiling water into the 9x13-inch pan to come about halfway up the sides of the springform pan. Bake until the cake has risen slightly, the edges are just beginning to set and a thin glaze (like a brownie crust) has formed on the surface, about 22 to 25 minutes. The cake should register 140 degrees on a digital thermometer.
  • Remove the cake from the water bath and set on a wire rack to cool completely to room temperature. Once cool, cover with plastic wrap and refrigerate at least 6 hours, or overnight (the cake can be refrigerated for up to 4 days).
  • About 30 minutes before serving, run a thin knife between the cake and sides of the pan; remove the sides of the pan. Place the cake on a serving platter, dust with powdered sugar and serve with a dollop of fresh whipped cream, if desired.

Notes

  • Chocolate: Bittersweet chocolate is also known as dark chocolate. For this particular cake, I recommend using chocolate with around a 60% cacao percentage. If you prefer your cake a little more bitter, go higher; if you prefer it a little more sweet, then you can go lower. I do not recommend using milk chocolate in this particular recipe, as it would be much too sweet.
  • Do NOT add sugar! You might be tempted to add sugar to the recipe to sweeten it up, but it will alter the texture of the cake; instead adjust the chocolate you use, as noted above.
  • Coffee: Coffee does a phenomenal job of enhancing the flavor of chocolate. You cannot taste the coffee in the finished product, so even if you dislike drinking coffee, I recommend you use it here. If you cannot drink coffee for medical, religious, or other reasons, you can substitute water.
  • Springform Pan: This recipe calls for an 8-inch springform pan, which is less common than its 9-inch cousin. If you don’t have one, I recommend this one.
  • Converting to 9-inch: If you do not have an 8-inch pan and prefer not to purchase one, you can still make this recipe in a 9-inch springform pan. Be aware that it will NOT fit inside of a 9x13-inch baking pan for the water bath and you will need to use something larger, like a roasting pan. The cake takes about the same amount of time to bake, but I would start checking at the 18-minute mark just to be safe.
  • Storage: This cake can be stored, covered, at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If you store it in the refrigerator, let it sit at room temperature for at least 30 minutes before serving.
  • Make-Ahead Instructions: This cake can be made up to one day in advance and kept in the refrigerator. The baked and cooled cake freezes exceptionally well. Wrap it tightly in a double layer of plastic wrap, then place in a freezer-safe zipper bag. Freeze for up to 3 months; thaw in the refrigerator overnight. (You can also freeze individual slices using the same instructions.)
