Moist Flourless Chocolate Cake : Easy Gluten-Free Recipe
For a recent birthday, my sister Lunetoiles whipped up this gorgeous flourless chocolate cake, a gluten-free treat that won over everyone at the table.
Who could resist sinking their spoon into that ultra-moist, intensely chocolatey center, all finished with crunchy chocolate decorations?
This cake is a true treasure for anyone who avoids gluten, but it’s just as irresistible for anyone who simply loves a rich, decadent dessert.
I completely fell for this recipe, though I wasn’t there to claim my slice, the photos alone make me want to reach through the screen and help myself!
What I love most is how simple the method is, even if it looks impressive. The secret? A luscious chocolate and egg mousse, with part baked for the base and the rest layered on top as a silky, melt-in-your-mouth topping.
It’s a fudgy, foolproof delight that proves gluten-free baking can be just as indulgent as any classic cake!

Ingredients for the Flourless Chocolate Cake
- 250 g dark chocolate : Choose high-quality chocolate with at least 60% cocoa for an intense flavor and rich, fudgy texture.
- 250 g sugar : Provides sweetness and balances the deep cocoa notes. You can slightly reduce the amount if you prefer a less sweet cake.
- 250 g unsalted butter : Cut into pieces for easier melting. The butter adds moisture, richness, and a smooth mouthfeel.
- 9 egg yolks : Use yolks at room temperature for easier mixing. They bring creaminess and help bind the ingredients together.
- 5 egg whites : Whip the egg whites until stiff peaks form. They lighten the batter, giving the cake its signature airy, mousse-like texture.

Step-by-Step Instructions for Flourless Chocolate Cake
- Preheat your oven to 170-180°C (340-355°F, gas mark 6) to ensure even baking.
- Grease a 24 cm (9-inch) springform pan with butter to make unmolding easier.
- Melt the chocolate in a heatproof bowl set over a pan of simmering water (double boiler). Once smooth, add the butter and mix until fully combined.
- Whisk together the sugar and egg yolks in a large bowl until the mixture becomes pale and doubles in volume. This step adds lightness and a fluffy texture.
- Add the melted chocolate and butter mixture to the sugar and yolk mixture. Stir well until completely smooth.
- Beat the egg whites with a pinch of salt until stiff peaks form.
- Stir one spoonful of whipped egg whites into the chocolate mixture to loosen it, mixing vigorously.
- Gently fold in the remaining egg whites with a spatula, lifting and turning the mixture to keep it airy.
- Pour half the batter into the prepared pan and smooth the top.
- Bake for 45 minutes, checking for doneness (a knife inserted should come out clean).
- Let the cake cool completely before spreading the remaining (uncooked) chocolate mixture on top.
- Refrigerate for at least 12 hours to allow the mousse to set.
- Carefully remove the ring from the pan.
- Dust the cake with unsweetened cocoa powder and decorate the sides with chocolate-coated biscuits or rolled wafer cookies for an elegant finish.

Storage and Serving Tips
- In the fridge: Store the cake in an airtight container or tightly wrapped to keep it fresh and moist for up to 3 days.
- In the freezer: The cake freezes well, either whole or sliced. Wrap it securely and let it thaw gently in the refrigerator before serving.
- At room temperature: Take the cake out of the fridge 20-30 minutes before serving to enjoy its soft, melt-in-the-mouth texture and full flavor.
- On a decorative platter: Present the cake on a stylish cake stand or under a glass dome for an elegant, festive touch at any celebration.
- Suggested accompaniments: Pair each slice with whipped cream, fresh berries, or a scoop of vanilla ice cream for an extra-indulgent treat.
