This Bittersweet Chocolate Cake, adapted from The Silver Palate Cookbook, has almost a pound of chocolate, a full dozen eggs, almost a pound of butter, and only one cup of flour.

If you were looking for a chocolate cake that represented the excesses of the 1980s, I cannot think of a better one than this!

No frosting, but with those ingredients, who needs frosting?

Since Julee Rosso and Sheila Lukins introduced the world to this cake decades ago it has become part of our national baking repertoire. It's like a pound cake, but with dark chocolate.

This cake manages to be both light and airy, while wonderfully rich and delicious, at the same time. Because the eggs provide so much structure, you can easily cut thin slices without having the cake fall apart.

Tips for making bittersweet chocolate cake

Making this bittersweet chocolate cake takes a little bit of baking skill, but is completely do-able. The parts that people may have trouble with are melting the chocolate, beating the egg whites, and folding the egg whites into the batter. Here are a few tips to help:

  • Whipping egg whites: When separating the eggs, make sure there are no bits of egg yolk in your egg whites. Any amount of fat in the egg whites will keep them from whipping up properly. Make sure your equipment — bowls and whisks or beaters — are spotlessly clean and free of any fat residue. Start on low speed and slowly increase the speed of your mixer.
  • Melting chocolate: Use chocolate meant for baking, not chocolate chips which have added stabilizers. Chop or grate the chocolate fine to make it easier to melt evenly. Add water to the chocolate before you heat them. Make sure that the bottom of the top bowl of your double boiler does not touch the water below it.
  • Folding beaten egg whites into the batter: Lighten the batter first by stirring in a third of the whipped egg whites until smooth. Then gently fold the remaining egg whites in, a third at a time, and do your best to not deflate the egg whites.

Prep Time 30 mins
Cook Time 90 mins
Total Time 2 hrs
Servings 20 servings

Ingredients

  • 12 large eggs, separated (see how to separate eggs)
  • 2 cups (400 g) granulated sugar
  • 14 ounces (400 g) bittersweet or semisweet chocolate, grated or cut into small pieces
  • 4 Tbsp (60 ml) water (or more if needed)
  • A pinch of salt
  • 3 1/2 sticks (3/4 lb plus 4 Tbsp, or 400 g) unsalted butter, softened
  • 2 teaspoons orange zest
  • 1 cup (135 g) all purpose flour, sifted
  • Powdered sugar

Method

  1. Preheat oven, prepare springform pan

    Preheat oven to 325°F. Prepare a rack in the center of the oven. Place a baking sheet in a rack below it (to catch any drippings or spill-overs).

    Generously butter the sides and bottom of a 9-inch or 10-inch springform pan. Add a few tablespoons of sugar and gently shake so that all the sides and bottom of the pan are coated with sugar. Tap out excess sugar.

  2. Beat egg yolks with sugar

    Beat egg yolks with the granulated sugar until they are thick and pale yellow and form a ribbon when they fall from the beater, about 2 to 3 minutes on medium speed of an electric hand mixer.

  3. Melt chocolate

    Make a double boiler by heating an inch of water to a bare simmer in a saucepan, and place a metal bowl on top of it. Make sure that the bottom of the metal bowl is not touching the water below.

    Place chocolate and 4 Tbsp of water together in the top metal bowl of the double boiler.

    Slowly melt the chocolate over barely simmering water, whisking it until smooth. If the chocolate gets too thick, and looks like it will firm up, whisk in a tablespoon more of water.

    Whisk in a pinch of salt.

    Let cool until just warm to the touch.

  4. Make batter base

    Slowly fold the warm chocolate into the egg mixture, gently stirring while you add the chocolate. Stir in the softened butter. Stir in the grated orange peel. Stir in the sifted flour. Mix thoroughly but gently.

  5. Incorporate beaten egg whites

    Beat the egg whites until stiff. (See this wonderful explanation of whisking egg whites taken from La Bonne Cuisine de Madame Sant-Ange.)

    Stir one third of the beaten egg whites in to the chocolate egg mixture to thin it. Gently fold in the remaining beaten egg whites, a third at a time until the egg whites are completely incorporated. Be careful at this stage not to over-mix.

  6. Bake

    Pour the batter into your prepared springform pan. The batter will come close to the top of the pan. Set the pan on the middle rack of your oven and bake at 325°F for 1 hour and 20 minutes, or until a cake tester comes out clean, or a digital thermometer inserted into the center reaches 200°F (93°C).

    Do not worry if the top of your baked chocolate cake has cracks in it! As the cake cools the top will settle and the cracks will close.

  7. Cool

    Cool on a rack for 15 minutes, then remove the outer rim. Allow the cake to cool completely before removing the bottom of the pan. Refrigerate.
