Ingredients

This recipe is beautifully simple, focusing on the exquisite quality of its core ingredients.

For the Cakes:

• 300 grams dark chocolate, finely chopped
• 150 grams unsalted butter, cut into cubes
• 6 large eggs
• 1 teaspoon vanilla flavoring
• 4 tablespoons caster sugar (superfine sugar)

For the Chocolate Glaze:

• 200 grams dark chocolate, finely chopped
• 1/3 cup heavy cream
• 85 grams unsalted butter, cut into cubes

Equipment Needed

To bring this exquisite flourless chocolate cake to life, you’ll need a few essential tools:

• A saucepan (preferably non-stick) for melting chocolate and butter.
• A stand mixer or a handheld electric mixer for whipping the eggs.
• A large bowl for combining ingredients.
• Eight 1-cup (8 fl oz) capacity non-stick muffin tins.
• A baking sheet to place the muffin tins on for easier handling.
• A spatula for folding and spreading.
• A wire rack for cooling.

Instructions

The magic of this flourless chocolate truffle cake lies in its straightforward preparation, allowing the quality of the chocolate to shine.

1. Preheat your oven to 325°F (170°C). This moderate temperature ensures the cakes cook through gently without drying out.
2. Prepare the muffin tins. Carefully line the base of each of the eight 1-cup (8 fl oz) capacity non-stick muffin tins with non-stick baking paper. This step is crucial for easy unmoulding later. Ensure the paper fits snugly at the bottom.
3. Melt the chocolate and butter. In a saucepan (ensuring it is absolutely dry to prevent the chocolate from seizing), combine the 300g of chopped dark chocolate and the 150g of cubed butter. Place the saucepan over low heat and stir gently and continuously until the chocolate and butter have completely melted and combined into a smooth, glossy mixture. Remove from heat immediately once smooth.
4. Whip the eggs and sugar. In the bowl of your stand mixer, or using a handheld electric mixer, combine the 6 large eggs and 4 tablespoons of caster sugar. Beat on medium-high speed until the mixture becomes thick, pale, and fluffy. This will take several minutes, and it’s essential for the cake’s structure.
5. Incorporate the chocolate mixture. Gently fold the warm (but not hot) chocolate and butter mixture into the whipped egg mixture. Use a spatula and a gentle folding motion to combine, being careful not to deflate the airy egg mixture. Stir until just combined and no streaks of egg remain.
6. Fill the muffin tins. Spoon the chocolate mixture evenly into the prepared muffin tins. Fill each tin almost to the top, leaving a tiny bit of space for expansion, though these cakes are quite dense.
7. Bake the cakes. Place the filled muffin tins on a baking sheet and bake in the preheated oven for 12-15 minutes. You are looking for the cakes to be just set. The edges should be firm, but the center may still be slightly soft. Overbaking will result in a drier cake.
8. Cool and chill. Once baked, remove the muffin tins from the oven and allow the cakes to cool completely in the tins. Once cool, refrigerate the cakes for at least 2 hours. This chilling period is vital for firming up the cakes and achieving that desirable truffle-like texture.
9. Prepare the chocolate glaze. While the cakes are chilling, prepare the glaze. In a clean saucepan, combine the 200g of chopped dark chocolate, 1/3 cup of cream, and 85g of cubed butter. Place over low heat and mix gently until everything is melted and smooth.
10. Chill the glaze. Remove the glaze from the heat and allow it to chill until it is firm enough to spread. You can speed this up by placing it in the refrigerator, stirring occasionally.
11. Assemble the cakes. Once the cakes are chilled and firm, and the glaze is ready, carefully unmould each cake from its muffin tin. Gently peel away the baking paper.
12. Glaze the cakes. Place the unmoulded cakes onto serving plates. Spread a generous amount of the chilled chocolate glaze over the top of each cake, allowing it to drip slightly down the sides for a rustic, elegant finish.

Expert Tips & Tricks

• Chocolate Quality is Key: Since this cake is so simple, the quality of your dark chocolate will make a monumental difference. Opt for a good quality chocolate with a cocoa content of at least 60-70% for the best flavor.
• Dry Equipment for Chocolate: When melting the chocolate and butter, ensure your saucepan and any utensils are completely dry. Even a tiny drop of water can cause melted chocolate to seize and become grainy.
• Don’t Overbake! The window for perfect flourless cakes is small. Aim for a texture that is set around the edges but still has a very slight wobble in the center. They will continue to firm up as they cool.
• Chilling is Non-Negotiable: That 2-hour chilling period isn’t just a suggestion; it’s essential for transforming these dense cakes into that luscious, truffle-like consistency. Don’t rush this step!
• Glaze Consistency: If your glaze becomes too hard to spread, gently warm it for a few seconds over very low heat or in a microwave in 10-second intervals, stirring well in between. If it’s too runny, chill it a little longer.

Serving & Storage Suggestions

These flourless chocolate truffle cakes are best served at room temperature to allow their rich flavors to fully develop. They are stunning on their own, perhaps with a dusting of cocoa powder or a single fresh raspberry. For an extra touch of elegance, consider serving them with a dollop of lightly sweetened whipped cream or a swirl of crème fraîche.

Storage:
Leftover cakes can be stored in an airtight container in the refrigerator for up to 3 days. The texture will become even denser and fudgier as they sit. They can also be frozen, well-wrapped, for up to 1 month; thaw them overnight in the refrigerator.

Variations & Substitutions

While this recipe is perfection in its simplicity, a few subtle tweaks can offer delightful variations:

• Orange Zest: For a sophisticated twist, add the finely grated zest of one orange to the chocolate mixture just before folding it into the eggs.
• Espresso Kick: Dissolve a teaspoon of instant espresso powder in the melted chocolate mixture for a deeper, more complex chocolate flavor.
• A Touch of Liqueur: A tablespoon or two of a good quality dark rum, brandy, or orange liqueur (like Grand Marnier) can be stirred into the melted chocolate mixture for an adult indulgence.

FAQs

Q: Can I make this cake in a larger, single round pan?
A: While the recipe is designed for individual portions, you could potentially bake it in a greased and floured 8-inch round cake pan. However, the baking time would need to be significantly increased, and the center might be difficult to judge for doneness without overcooking the edges. The individual muffin tins ensure even cooking and perfect truffle-like results.

Q: My chocolate seized when melting, what went wrong?
A: Chocolate seizing is usually caused by the introduction of moisture. Ensure your saucepan, spatula, and all ingredients are completely dry when melting chocolate. Avoid adding any water or steam directly to the chocolate.

Q: How do I ensure the cakes are truly “just set” and not overbaked?
A: The edges should look set and slightly firm to the touch, while the very center should still appear moist and have a slight give when gently nudged. They will continue to cook slightly from residual heat as they cool.

Q: Can I use different types of chocolate?
A: You can experiment with different percentages of dark chocolate. However, avoid using milk chocolate or white chocolate, as their lower cocoa solids and higher sugar content will significantly alter the texture and richness of the cake.

Q: How should I store the leftover glaze?
A: Leftover glaze can be stored in an airtight container in the refrigerator. Reheat gently over low heat or in short bursts in the microwave until spreadable again.
