Recipe Summary

Makes one 10-inch cake


Ingredient Checklist


Instructions Checklist
  • Heat oven to 300 degrees. Grease a 10-inch springform pan with 1 tablespoon butter, and dust generously with granulated sugar.

  • Melt chocolate and butter over simmering water in a double boiler, about 6 to 8 minutes. Remove from heat and set aside to cool.

  • In an electric mixer fitted with the whisk attachment, whip yolks and whole egg with 2/3 cup sugar on a high speed, until it is pale yellow and falls in a thick ribbon when the beater is raised, about 5 minutes. Scrape down the sides of the bowl once or twice during mixing. Set aside.

  • In an electric mixer, using a second whisk attachment and bowl, (both should be clean and free of grease) whip egg whites with remaining 1/3 cup sugar on high speed until thick and foamy, about 3 to 4 minutes. Set aside. While egg whites are beating, add the cooled, melted chocolate slowly to the yolk mixture.

  • Temper whipped egg whites by mixing in about 1/4 cup of the chocolate mixture. Then gently fold egg whites into the chocolate yolk mixture, working quickly to maintain the volume of egg whites; the mixture will have a slightly marbleized appearance.

  • Pour batter into prepared pan, and place on a parchment-lined baking sheet. Bake in oven for 50 to 60 minutes. Remove from oven and allow to cool in the pan on a cooling rack. When completely cool, gently run a knife around the edges of the pan and release spring. Dust with cocoa powder or confectioners' sugar before serving.

I made this recipe and it turned out really well! My egg whites didn't peak and it still turned out good! It tasted like a fluffy brownie. I would recommend this recipe!

Well, we made this cake twice: both totally unsuccesful and both times following the directions. First time we baked it for 50 minutes: next 65. Both came out wet and eggy. And we're pretty good in the kitchen. Either somethings missing in the ingredients or it's just not a good recipe. Very disappointing. We do not recommend using this recipe. Has anyone else tried it (besides the person who commented 3 years ago)?

This cake is outstanding! Since it is flourless - It is a must at our Passover celebrations ... My birthday usually falls during passover- and as a kid I could never get a "good" cake - now I have a son who's birthday usually falls in Passover - and he can't wait - because he knows he is getting the Best Chocolate cake ever . Highly recommend for all occassions..
