Bitter Orange Flourless Chocolate Cake
Chocolate is a separate food group in my household and just like protein, I can’t live without it. Whenever I order a dessert in a restaurant, it is the chocolate desserts I gravitate to. However, I hesitate whenever I see a flourless chocolate cake on the menu because I do not know if it going to be fudge or cake. When it comes to flourless chocolate cake, I like them on the lighter side, not the ones that taste like dense fudge. It is not that I believe they taste bad, it is just they are very rich. The type of flourless chocolate cake I prefer, have a lighter airy texture, despite being moist and loaded with dark chocolate.
So far, I have come across two flourless chocolate cake recipes that satisfy my requirement of biting into a slice of cake, not a chunk of fudge. What makes them different from most flourless chocolate cake recipes out there is the use of finely ground nuts and whipped egg whites. The nuts act like a flour replacement and give the cake some texture and body. Also, because of the whipped egg whites, there is some air which gives the cake some lift and tastes light. Just like brownies, the cake is fudgy without being dense.
The only challenging aspect to making a flourless chocolate cake is how fragile they are. Especially the types of cakes I prefer. Without the gluten to hold it together, the cake can easily break and crack. Transferring the cake off the bottom of the springform pan onto a serving dish requires the strength of all the good karma, prayers and best wishes you can muster. As well as patience and your best problem-solving skills. It is a very moist cake, especially in the middle which makes it very delicate.
My recipe is adapted from Diana Henry’s Bitter Flourless Chocolate Cake recipe in her cookbook, Simple. She uses ground almonds which I love, but I could not bring myself to use almonds a day after I wrote a post about Earth Day Recipes and how growing almonds in California is depleting their water supply. I will not give up almonds altogether, but I should leave some time before I start using them again.
Flourless Chocolate Cake Variations
In my recipe I substitute almonds with ground walnuts and I added orange zest and Grand Marnier. Chocolate pairs well with many types of nuts, so you can’t go wrong using any type of nut. I do love walnuts and chocolate, especially with bitter orange flavors from orange zest and orange flavored liqueur. I kept all the proportions the same, but I also added Grand Marnier for an extra orange punch. There is just enough of the walnuts for a subtle nut flavor with the dark chocolate the focal point.
However, the addition of Grand Marnier makes the cake more fragile than without it. I believe this is because of the extra moisture in the cake batter. I don’t believe baking it longer will help. If you are concerned about the final show stopping appearance, then don’t add the Grand Marnier. The whipped cream has Grand Marnier in it, so the dessert will have the great chocolate and boozy orange flavor.
Removing the cake off the bottom of the spingform pan is challenging with this moist and delicate cake. If you don’t care, remove the sides of the pan and place the cake still on top of the pan’s bottom, on a serving plate. No one will care or notice while they are enjoying your delicious cake. Or, you can try lining the bottom of the pan with parchment paper to see if that helps. If your cake does break don’t despair, you can break it up and make ice cream sundaes with chocolate and vanilla ice cream, dark chocolate sauce, whipped cream with orange flavors and candied orange peel. Or, cut the cake up into bite size pieces for people to nibble on with their coffee or tea.
Orange Essence Flourless Chocolate Cake is worth making regardless of its delicate nature. Because the chocolate is the dominate flavor, use the best quality of chocolate you can buy with 70%- 72% cocoa butter. I have great success with Lindt chocolate and Ghirardelli Intense Dark Chocolate, twilight delight found in candy section of the grocery store. Here is a link for more information on the best chocolate bars for baking from Serious Eats.

- 11.5 oz (328 g) good quality dark chocolate, broken into pieces 70% coco solids
- 3/4 cup (164 g) super fine sugar
- 5 large eggs, separated
- 1/2 cup (57 g) ground walnuts (see note)
- finely grated zest from half a navel orange
- 2 TB Grand Marnier Optional

- 1 cup heavy whipping cream
- 1 TB confectioners' sugar or to taste

For the Cake
Preheat the oven to 350 °F (177°C /Gas Mark 4) oven. Butter an 8-inch (20 cm) springform pan. Set aside.
In a medium metal mixing bowl, add the broken-up chocolate, the butter and sugar to the bowl.
Add some water to a large 10-inch (25.5 cm) skillet just enough to cover the bottom of the pan. Set on a burner over medium heat. Bring the water to a gentle simmer and place the bowl with the chocolate, butter and sugar in the center of the skillet. Melt the chocolate and butter, stirring occasionally. Do not let the water get to a brisk boil. Keep it at a gentle simmer, being careful not to splash water into the chocolate.
Remove the bowl from the skillet just before all the butter has melted and stir until all the chocolate and butter has melted. Let the chocolate cool for four minutes.
Add the egg yolks one at a time to the chocolate, stirring between each addition until each yolk is incorporated.
In a separate bowl, with a stand mixer or hand-held mixer, beat the egg whites until stiff with soft peaks and still wet. Soft peaks will form when you lift out the beaters. Gently fold in the Grand Marnier if using.
Add the orange zest to the ground walnuts and mix together. Add the walnut mixture to the chocolate and half of the whipped egg whites. Fold into the chocolate. Then fold in the remaining egg whites.
Pour the batter into the prepared springform pan and place on a rimmed sheet pan in case it leaks. Place the cake in the oven and bake for 35 minutes.
Remove the cake from the oven and cool on a cake rack. Don't get upset if you see the cake deflate and crack as it cools. When the cake is completely cool, unlatch the pan and carefully remove the sides. Run an icing spatula, or thin sharp knife under the cake to loosen. It helps to clean off the spatula or knife every time you pull it out from under the cake. Carefully transfer the cake onto a serving plate.
Dust the cake with confectioners' sugar right before serving.
Right before serving, use a hand-held mixer and whip the heavy cream until it just holds its shape. Sprinkle in the confectioners' sugar and Grand Marnier, if using. Whip until combined soft peaks form. Taste and correct the whipped cream for sweetness and the Grand Marnier. Place in a small serving bowl.
Serve the whipped cream with the cake and extra fruit, like berries.
Before you start the cake, toast the walnuts in a preheated 350°F (177 °C / Gas Mark 4) oven. Spread a couple of handfuls (60 g) of the walnuts over a small rimmed baking sheet. Toast in the oven for 7 minutes. Spread the toasted walnuts over a clean lint free kitchen towel. Fold a portion of the towel over the nuts to cover and rub the towel with the walnuts back and forth to remove the walnut skin. No need to go crazy rubbing off all the skin. Rub back and forth a few times until no more skin comes off without scrubbing. Collect the walnuts leaving the loose skin behind and grind the walnuts in a food processor.
