Ingredients for Moelleux au Chocolat

Creating this magnificent cake chocola requires simple, high-quality ingredients to achieve its signature rich flavor and texture. Here’s what you need:

• 225 g unsalted butter, cut into cubes, plus extra for greasing (16 tbsp / 1 cup)
• 225 g good-quality 70% dark chocolate, roughly chopped (8oz / 1 cup)
• 75 g cocoa powder, 3/4 cup
• Pinch of salt
• 7 large eggs
• 265 g caster sugar, 1 1/3 cups / 9.3 oz (known as superfine sugar in the US)
• For Serving: Double cream, ice cream, or custard

Notes & Substitutions

For the best results, always use unsalted butter so you control the salt content. Opt for a good quality 70% dark chocolate; this will truly elevate the flavor of your molten chocolate cake. Ensure your cocoa powder is unsweetened; Dutch-processed is often preferred for deeper color and flavor. Understanding the difference between Dutch-processed and natural cocoa powder can impact the final flavor and leavening of your baked goods. Caster sugar (superfine) dissolves more easily, yielding a smoother batter. Always use large eggs as they are essential for the structure and richness of this recipe. Feel free to add fresh berries, a dusting of icing sugar, or toasted nuts when serving for extra flair.

Equipment

You don’t need fancy tools to bake this stunning chocolate dessert. Gather these essentials:

• A 23cm (9-inch) round springform tin
• Mixing bowls (at least three)
• An electric whisk or stand mixer
• A rubber spatula or spoon for folding
• A fine-mesh sieve
• A baking tray

Instructions: How to Make Your Melt-in-the-Middle Chocolate Cake

Follow these steps carefully to create your perfect Moelleux au Chocolat, resulting in a show-stopping cake chocola.

1. Prepare Your Tin: Preheat your oven to 180C Fan/355F Fan (or 200C/400F if not fan). Generously butter a 23cm (9-inch) round springform tin. Line the base with non-stick baking paper. Set this aside.
2. Melt Chocolate and Butter: Melt the butter and chocolate together in a heatproof bowl. You can use a microwave in 30-second bursts, stirring well each time until smooth. Alternatively, place the bowl over a pan of « just » simmering water, ensuring the bowl’s bottom doesn’t touch the water to prevent burning.
3. Add Cocoa and Salt: Once you have a smooth, glossy mixture, place a sieve over the bowl. Sift in the cocoa powder and a pinch of salt. Stir until the mixture is completely smooth. Set this aside.
4. Separate Eggs: Carefully separate the eggs. Put the whites into the bowl of a stand mixer. Place the yolks into another large mixing bowl.
5. Whisk Egg Yolks: Add 135 g of caster sugar to the egg yolks. Whisk this mixture using an electric whisk for about 2 minutes, until it becomes pale, light, and noticeably thick.
6. Whisk Egg Whites: Using the stand mixer (or a thoroughly cleaned electric whisk), whisk the egg whites until they form soft peaks. Gradually add the remaining sugar, continuing to whisk until the egg whites are stiff and glossy.
7. Combine Mixtures: You now have three bowls of components. First, pour the melted chocolate mixture into the egg yolks and stir gently to combine. Next, add two spoons of the whisked egg whites into this chocolate mixture and stir quite vigorously. This « sacrificial spoon » step helps lighten the batter without worrying too much about deflating the egg whites.
8. Fold in Remaining Whites: Gently fold in the remaining egg whites using a spatula. Take great care to keep as much air in the mixture as possible. Continue folding until you no longer see any streaks of egg white.
9. Bake the First Layer: Pour two-thirds of the cake batter into your prepared tin. Bake for approximately 25 minutes, or until the cake is well risen, puffy, and a skewer inserted into the center comes out clean. Allow this layer to cool completely in the tin.
10. Reserve Batter: Meanwhile, pour the remaining one-third of the cake chocola batter into a medium bowl and set it aside. If you plan to use it much later, cover it with cling film and refrigerate it. This will become your molten top layer.
11. Prepare for Second Bake: Once the first layer has cooled completely, preheat the oven again to 180C Fan. Line a baking tray with non-stick baking paper and set aside.
12. Add Molten Layer: Remove the cooled cake from its springform tin and place it onto the prepared baking tray. Spread the reserved one-third of the batter evenly over the top of the cooled cake. If the batter was refrigerated, it might be thicker, so gently spread it with a palette knife.
13. Bake Second Layer: Bake the cake for another 10-15 minutes. Look for a thin crust to form on the top, but ensure the middle is still soft and jiggly underneath. This is key for the molten center.
14. Rest and Serve: Remove the molten chocolate cake from the oven and let it stand for 10 minutes before slicing. Cut into generous slices and serve warm with your chosen accompaniment, or enjoy it chilled from the fridge for a fudgier texture.

Pro Tips for the Perfect Moelleux au Chocolat

Achieving that signature melt-in-the-middle requires a few key techniques.

• Accurate Weighing: Always weigh your ingredients using a kitchen scale. This ensures the precise ratios needed for the perfect texture in your cake chocola.
• Gentle Folding: When incorporating the egg whites, fold them in gently. Overmixing will deflate the batter and prevent a light, airy texture.
• Avoid Overbaking: The second bake is crucial. Watch for a thin crust, but ensure the center remains jiggly. An underbaked middle is exactly what you want for that molten effect.
• Embrace the Slump: Don’t worry if your flourless cake naturally slumps a little after cooling. This is normal and adds to its rustic charm and dense, rich quality.
• Cleanliness is Key: Ensure your whisk and bowls are spotless and grease-free before whisking egg whites. Even a tiny bit of fat can prevent them from reaching stiff peaks.

Serving Suggestions, Storage & Variations

This versatile cake chocola offers many delightful ways to enjoy it. Serve your Moelleux au Chocolat warm for that irresistible molten center, or chilled for a wonderfully dense, fudgy experience. It pairs beautifully with a dollop of cold double cream, a scoop of vanilla bean ice cream, or a warm, silky crème anglaise (custard). Garnish with fresh raspberries, a vibrant berry coulis, or some toasted slivered almonds for extra crunch. Store any leftovers covered in the fridge for up to 3 days. You can even bake the bottom layer up to 2 days in advance, letting it cool completely before storing, then adding the molten top and baking just before serving. Experiment with different percentages of dark chocolate, like 60% for a slightly sweeter finish or 80% for an even more intense cocoa flavor.
