Why This Chocolate & Clementine Cake Will Become Your New Favorite
What makes this particular cake so extraordinary? Imagine a dessert with a center that’s incredibly moist and dense, yet never heavy. It boasts an irresistible crackly top, chewy edges, and a gloriously gooey middle, each bite bursting with the vibrant essence of fresh citrus. And here’s the best part: it’s entirely gluten-free! Thanks to the absence of traditional flour, the cake achieves a unique, shallow depth, yet its incredible richness ensures that a standard portion size is perfectly satisfying. This innovative recipe ingeniously combines elements of a classic cake with the airy lightness of a pavlova, using stiffly beaten egg whites to bind the ingredients and create volume without gluten.
The Unexpected Star: High-Quality Olive Oil in Baking

While olive oil might seem an unconventional choice for a dessert, it is, in fact, one of the most luxurious and flavorful fats you can incorporate into baking. It infuses the cake with a delicate, fruity undertone that perfectly complements the rich chocolate and zesty clementines. When baking with olive oil, quality is paramount. For this recipe, we highly recommend Rich Glen Olive Oil. Their commitment to superior quality ensures a truly exceptional flavor profile that elevates this cake from delicious to unforgettable.
For an extra layer of citrus brilliance, we’ve specifically utilized Rich Glen’s Citrus Zest Infused Olive Oil. This ingredient is a game-changer, imparting an unbelievably unique and special flavor that will have everyone clamoring for your recipe. The subtle peppery notes and bright aroma of a premium olive oil, especially one infused with citrus, enhance the overall complexity of the cake, creating a truly gourmet experience.

The Zesty Heart: Clementines (or Your Favorite Citrus)
The clementines used in developing this recipe were perfectly in season, bursting with juice and fragrance. Their sweet and tangy flavor is essential to balancing the richness of the dark chocolate. If clementines or mandarins are not available, fear not! Oranges make an excellent substitute, offering a similar delightful citrus punch. Regardless of your choice of fruit, remember this golden rule: do not skimp on the zest! The zest carries the most concentrated citrus oils, delivering that essential bright, aromatic flavor throughout the cake.
Beyond their flavor, citrus fruits also contribute to the cake’s moisture and tender crumb. The natural acidity helps to tenderize the gluten-free batter, resulting in a cake that melts in your mouth. This cake is a celebration of seasonal produce, transforming simple ingredients into a sophisticated dessert.
Perfect for Any Special Occasion
Topped generously with extra clementine zest, a delicate dusting of icing sugar, and a dollop of freshly whipped cream, this gluten-free chocolate cake stands proudly alongside—or even surpasses—its traditional flour-based counterparts. Its elegant appearance and intensely satisfying flavor make it the most perfect dessert for life’s special moments. Whether you’re celebrating a birthday, an anniversary, or sharing a romantic Valentine’s Day treat, this cake is guaranteed to impress and delight. Its rich, dark aesthetic and vibrant citrus aroma create a sensory experience that is truly unforgettable.

Baking Tips for Perfection: Elevating Your Clementine Olive Oil Cake
Achieving baking perfection is all about paying attention to the details. Follow these essential tips to ensure your Chocolate Fudge Clementine Olive Oil Cake turns out absolutely flawless:
- Embrace High-Quality Olive Oil: The choice of olive oil profoundly impacts the flavor. A premium extra virgin olive oil, especially one infused with citrus zest like Rich Glen’s, will impart a delicate fruitiness and depth that no other fat can replicate. It’s not just a cooking oil; it’s a flavor enhancer.
- Select Superior Dark Chocolate: This cake is a chocolate lover’s dream, so the quality of your chocolate matters immensely. Opt for dark chocolate with at least 80% cacao content. High-quality chocolate melts smoothly, provides intense flavor, and contributes to the fudgy texture. Avoid using chocolate chips, as they often contain stabilizers that prevent them from melting properly.
- Room Temperature Eggs are Crucial: Ensure your eggs are at room temperature before you begin. This allows the egg whites to whip up to their maximum volume, creating a stable meringue that provides lift and structure to the cake without relying on flour. Cold eggs simply won’t achieve the same fluffy consistency.
- Slow and Steady Wins the Whipping Race: When incorporating sugar into your egg whites, patience is key. Add the sugar slowly, tablespoon by tablespoon, allowing approximately one minute between additions. This gradual process ensures the sugar fully dissolves into the egg whites, resulting in a smooth, glossy, and stable meringue that won’t weep or collapse.
- Master the Art of Baking Time: Overbaking will lead to a dry, crumbly cake, while underbaking will result in a sunken, overly moist, and dense center. Begin checking for doneness around the 45-minute mark. Insert a wooden skewer into the center of the cake; it should come out with a few moist crumbs attached, but not wet batter.
- Use the Correct Cake Tin Size: The specified 23cm / 9-inch silicone cake tin is important for achieving the cake’s intended texture and shallow, rich profile. A silicone tin also aids in easy removal. Using a different size might alter the baking time and the final consistency of your cake. For easy removal and that rustic, crinkled edge, make sure the baking paper extends over the edges, acting as handles.

Frequently Asked Questions About This Delicious Cake
We know you’ll have questions when embarking on a new baking adventure. Here are some of the most common inquiries about our Chocolate Fudge Clementine Olive Oil Cake:
Can I make this cake the day before?
Absolutely! This cake has a wonderful quality of actually improving with time. While it’s undeniably delicious warm from the oven, making it a day in advance allows the flavors to meld and deepen, enhancing its rich profile. Simply store it in an airtight cake tin on your kitchen counter.
How long does the cake keep for?
While we guarantee there won’t be many leftovers, if you do manage to save some, this cake will keep beautifully. Store it in an airtight container or cake tin at room temperature for up to 5 days. It remains wonderfully moist and flavorful.
What if I can’t find flavored olive oil?
No problem at all! A high-quality extra virgin olive oil will work perfectly. To compensate for the missing citrus infusion, simply add a little extra clementine zest (or orange zest) to the batter. This will help to further enhance and bring out those bright, zesty notes in your cake.
Can I substitute a different citrus fruit?
Yes, you can! While clementines offer a unique sweet-tart balance, oranges, mandarins, or even Meyer lemons (for a slightly tarter cake) can be used. Ensure you adjust the sugar slightly if using a much more tart fruit. The key is to use fresh juice and plenty of zest.
What kind of chocolate is best for this cake?
As mentioned in our tips, dark chocolate with at least 80% cacao is highly recommended. This ensures a rich, deep chocolate flavor that isn’t overly sweet, providing a perfect contrast to the citrus. High-quality baking bars or blocks are ideal.

The Recipe: Chocolate Fudge & Clementine Cake
Chocolate Fudge & Clementine Cake
By Daen Lia
A decadently rich cake with a fudge-like center and beautiful notes of citrus throughout, perfect for gluten-free indulgence.
Prep Time: 30 mins | Cook Time: 50 mins | Servings: 6
Ingredients
- 4 eggs, room temperature
- 200 g dark chocolate (at least 80% cacao)
- 3/4 cup Rich Glen Orange Citrus Zest Infused Olive Oil (or high-quality extra virgin olive oil + extra zest)
- 1 cup sugar
- 1/2 cup clementine juice (freshly squeezed)
- 2 tbsp clementine zest, + extra to serve
- 1/4 tsp flaky sea salt
- Icing sugar, to serve
- Whipped cream or ice cream, to serve
Instructions
- Preheat your oven to 180°C (350°F). Lightly oil a 23cm / 9-inch silicone cake tin. Line the bottom and sides with a piece of baking paper, ensuring it extends over the edges to create “handles” for easy removal. This also contributes to the cake’s beautifully crinkled, rustic appearance.
- Break the dark chocolate into smaller pieces and place them in a heatproof bowl. Set the bowl over a pot of simmering water, ensuring the bottom of the bowl does not touch the water. Whisk gently until the chocolate is fully melted and smooth. Remove from heat and allow to cool slightly while you prepare other ingredients.
- Carefully separate the egg yolks from the egg whites. In a large mixing bowl, combine the egg yolks with half of the sugar, the slightly cooled melted chocolate, olive oil, clementine juice, and clementine zest. Whisk thoroughly until all ingredients are well combined and the mixture is smooth and emulsified.
- In a stand mixer (or using an electric hand mixer) on the highest speed, beat the egg whites with a tiny pinch of salt until they form soft peaks. Once they begin to stiffen, gradually add the remaining sugar, one tablespoon at a time, allowing approximately one minute between each addition to ensure complete dissolution. Continue whisking until the egg whites are stiff, smooth, and glossy, forming firm peaks.
- Very gently fold the stiff egg white mixture into the chocolate batter. Use a spatula and a light hand, trying not to deflate the air pockets in the egg whites. It’s perfectly fine if the batter has a marbled appearance and the egg whites are not fully mixed through; this contributes to the cake’s unique texture.
- Pour the delicate batter into your prepared cake tin. Bake for 50 minutes. After baking, allow the cake to rest in the tin for 15 minutes before carefully using the baking paper handles to lift it out. Transfer the cake to a cooling rack. Once completely cool, lightly dust with icing sugar and sprinkle with extra clementine zest.
- Serve slices warm or at room temperature, accompanied by a generous dollop of freshly whipped cream or a scoop of your favorite ice cream. Enjoy!
