FULL RECIPE:

Ingredients:

• 2 small thin-skinned oranges (approximately 375g total weight)
• 6 large eggs
• 1 heaped teaspoon baking powder
• ½ teaspoon bicarbonate of soda
• 200g ground almonds
• 250g caster sugar
• 50g cocoa powder
• Orange peel, for decoration (optional)

Directions:

1. Place the whole oranges in a saucepan, cover with cold water, and bring to a boil. Cook for 2 hours or until soft. Drain and let them cool.
2. Preheat the oven to 180°C (350°F). Butter and line a 20cm (8-inch) springform tin.
3. Once cooled, cut the oranges in half and remove any seeds. Then, pulp everything—peel, pith, and all—in a food processor.
4. Add the eggs, baking powder, bicarbonate of soda, ground almonds, sugar, and cocoa to the processor. Blend until you achieve a cohesive batter.
5. Pour the batter into the prepared tin and bake for approximately 45 minutes to an hour, or until a skewer inserted into the center comes out clean. If the top starts to burn, cover it with foil.
6. Remove from the oven and let the cake cool in the tin on a cooling rack. Once cooled, remove from the tin and decorate with orange peel if desired.

The Magic Behind the Ingredients

One of the most intriguing aspects of this cake is its use of whole oranges. Unlike many other cakes that rely solely on zest or juice, this recipe incorporates the entire fruit—peel, pith, and all. This method intensifies the citrus aroma and provides a gentle bitterness that complements the cocoa. The oranges are boiled until tender before being blended into a puree, ensuring they integrate seamlessly into the batter. This technique also eliminates any harsh bitterness that raw orange peels might have. Cocoa powder plays a crucial role in adding depth to the cake. Unlike traditional chocolate cakes that rely on melted chocolate, this recipe uses unsweetened cocoa, which enhances the intensity of the chocolate flavor. Combined with the natural sweetness of the oranges and sugar, the result is a well-balanced taste that isn’t overly sweet. Ground almonds replace the flour, offering both structure and a delicate nutty undertone. Almonds not only make the cake gluten-free but also contribute to its tenderness. The oils in almonds keep the cake moist for days, making it an excellent make-ahead dessert option. Eggs serve as the binding agent, ensuring the cake holds together without the need for flour. They also contribute to the cake’s airy yet rich texture, preventing it from becoming too dense. The combination of eggs, almonds, and cocoa creates a firm yet delicate crumb that remains soft and flavorful even after several days.

Why This Cake is Perfect for Special Occasions

This flourless chocolate orange cake is an excellent choice for celebrations, whether it’s a birthday, holiday gathering, or a simple dinner party. Its naturally rich and moist texture means it requires no frosting or glaze, though it pairs beautifully with a dusting of powdered sugar, a dollop of whipped cream, or even a scoop of vanilla ice cream. The bright citrus notes from the oranges add a refreshing contrast to the deep cocoa flavor, making it a sophisticated yet comforting dessert. For those who love baking but want something unique, this cake offers an exciting departure from traditional chocolate cakes. The use of whole oranges and the absence of flour make it an interesting recipe to try, especially for those looking to expand their gluten-free baking repertoire.

The Health Benefits of a Flourless Cake

This cake is not just delicious but also offers some surprising health benefits. Since it is gluten-free, it is a fantastic alternative for those with gluten intolerance or celiac disease. The absence of butter and milk makes it a great option for individuals who are dairy-free as well. Almonds are packed with healthy fats, fiber, and protein, making them a nutritious alternative to processed flour. They also contain vitamin E, magnesium, and antioxidants, which are beneficial for heart health. The use of whole oranges provides a boost of vitamin C, which supports the immune system and skin health. Compared to traditional cakes that use refined flour and butter, this flourless chocolate orange cake is lower in empty carbohydrates and higher in nutrient-dense ingredients. While it still contains sugar, its richness and natural flavors mean that it doesn’t rely on excessive sweetness to be enjoyable. This makes it a slightly healthier indulgence compared to many other desserts.

Serving and Pairing Ideas

One of the best things about this cake is its versatility in serving. While it is absolutely delicious on its own, there are several ways to enhance the experience. A light dusting of powdered sugar can give it a classic, elegant finish. For a richer touch, a drizzle of dark chocolate ganache can elevate the deep cocoa flavor. If you prefer a contrast in textures, serving it with a scoop of vanilla ice cream or a spoonful of lightly sweetened whipped cream adds a creamy balance to the dense, moist cake. For a more sophisticated presentation, garnish with candied orange slices or a sprinkle of finely grated dark chocolate. If you love a bit of crunch, crushed roasted almonds or hazelnuts can be sprinkled over the top. The cake also pairs well with coffee, espresso, or a glass of dessert wine, enhancing its bold chocolate and citrus notes.

Conclusion

Nigella Lawson’s Flourless Chocolate Orange Cake is a timeless and elegant dessert that is as delicious as it is unique. Its combination of rich cocoa and vibrant orange creates a beautifully balanced flavor that is both indulgent and refreshing. The absence of flour makes it an excellent gluten-free option, while the use of whole oranges adds a natural sweetness and depth that sets it apart from traditional chocolate cakes.
