Flourless Dark Chocolate Cake

Here’s a simple cake that’s rich, elegant and over-the-top chocolaty. For finishing touches, add powdered sugar, cocoa or liqueur-flavored whipped cream. —Marie Parker, Milwaukee, Wisconsin
  • Total Time
    Prep: 25 min. Bake: 30 min. + cooling
  • Makes
    12 servings


  • 4 large eggs, separated
  • 3 tablespoons butter
  • 8 ounces dark baking chocolate, chopped
  • 1/3 cup plus 1/4 cup sugar, divided
  • 1 container (2-1/2 ounces) prune baby food
  • 1-1/2 teaspoons vanilla extract
  • Confectioners' sugar


  • Place egg whites in a small bowl; let stand at room temperature 30 minutes. Preheat oven to 350°. Coat a 9-in. springform pan with cooking spray; place on a baking sheet.
  • In a small saucepan, melt butter and chocolate over low heat, stirring constantly. Remove from heat; cool slightly. In a large bowl, beat egg yolks on high speed 3 minutes or until slightly thickened. Gradually add 1/3 cup sugar, beating until thick and lemon-colored. Beat in baby food, vanilla and the chocolate mixture.
  • With clean beaters, beat egg whites on medium until soft peaks form. Gradually add remaining sugar, 1 tablespoon at a time, beating on high after each addition until sugar is dissolved. Continue beating until stiff glossy peaks form. Fold a fourth of the whites into chocolate mixture, then fold in remaining whites.
  • Pour into prepared pan. Bake until a toothpick inserted in center comes out with moist crumbs, 30-35 minutes. Cool on a wire rack 20 minutes. Loosen sides from pan with a knife; remove rim from pan. Cool cake completely. Dust with confectioners’ sugar before serving.

    I made this for a birthday event. It turned out beautifully. I had to use pureed pumpkin instead of prunes (it is what I had available). No one knew the secret ingredient. I would make it again for sure. I also added one teaspoon of king arther espresso powder heighten the rich chocolate flavor.

    I made this delicious cake today and followed the recipe to the letter. It was not difficult but had several steps that went quickly. I used a bread knife to chop the chocolate and it makes quick work of it. I used the bars of unsweetened chocolate. I would recommend serving this cake with either whipped cream of ice cream. It is very chocolately.Volunteer Field Editor

    I do not know what I did wrong, but my dough was so stiff I couldnt fold in egg whites. I used two boxes Bakers unsweetened chocolate (4 oz each). I had to throw it away it was so bad. I think it had to do with the quantity of chocolate I put in. Any suggestions. Sukie

    For those who asked about using baking chips, you would use 8 oz. (by weight) of the baking chips. Measuring in an 8 oz. cup would not be the same. Use a food scale. This recipe looks yummy!

    Made this for my valentine. It was really good. I didn't change anything in the recipe. My hubby said he felt like we were on a cruise with the lovely meal and delicious dessert. Next time I will line the pan with parchment paper. I was sure I could get it off the pan without breaking the cake.

    This is DECADENT. Delicious. Amazing. The taste is fabulous. The look... well, its not quite pretty enough for a fancy desert. The photos is about how ours turned out. It does look a lot better once its cut and on your plate. I'm planning to make this again as brownies, instead of a cake, since we don't have such high expectations about how pretty brownies should look.

    This cake is sooo good! The texture is dense, but the top is light and flaky. The chocolate flavor is intense and delicious. I loved the rustic look of it. Served a Cointreau flavored whipped cream alongside - yum!
