100g (1/2 cup) caster sugar – sweetens the cake while ensuring a fine texture.

50g (1/3 cup) plain flour – adds structure to the cake without overpowering the chocolate.
40g (1/4 cup) self-raising flour – ensures the cake rises beautifully, resulting in a light texture.

How to Make Dark Chocolate Mousse Cake
Follow these simple steps to prepare this delicious Dark Chocolate Mousse Cake:
Step 1: Preheat Your Oven
Begin by preheating your oven to 160°C (140°C fan-forced). Grab a 22cm springform pan, release the base, invert it, and line the bottom with baking paper. Grease the sides with a bit of melted butter to make sure your cake slides out smoothly later.
Step 2: Create the Base
In a heatproof bowl, combine the finely chopped dark chocolate, unsalted butter, caster sugar, and hot water. Place this bowl over a pot of simmering water, ensuring the bowl doesn’t touch the water. Stir gently until all the ingredients meld into a deliciously smooth mixture. Remove from the heat and let it cool a bit.
Step 3: Mix the Dry Ingredients
Now it’s time to stir in the plain flour, self-raising flour, cocoa powder, and the egg into your melted chocolate mix. A spatula works wonders here! Pour this dreamy batter into your prepared pan and pop it in the oven. Bake for about 25 minutes or until a skewer poked into the center comes out clean.
Step 4: Cool and Prepare the Mousse
Once baked, let the cake cool completely in the pan. Meanwhile, create the mousse by placing the remaining dark chocolates in a heatproof bowl over simmering water (remember, no touching!). Stir until melted and smooth, then set aside to cool slightly.
Step 5: Whip It Up
In a separate bowl, beat the thickened cream until you achieve soft peaks. Gently fold a third of the whipped cream into the cooled chocolate mixture, followed by the rest, ensuring it all combines beautifully without losing that airy texture.
Step 6: Assemble and Chill
Pour the luscious mousse over your cooled cake, smoothing the top with a spatula. Tap the pan on the counter gently to release any air pockets, then place it in the fridge. Let it chill for at least 6 hours or overnight for best results.
Step 7: Make the Glaze
When it’s finally time to indulge, prepare the glaze by combining dark chocolate, thickened cream, and liquid glucose in a saucepan over low heat. Stir until melted and smooth. Allow it to cool slightly before pouring it over the chilled mousse. Once glazed, chill again for about an hour before serving.
This Dark Chocolate Mousse Cake is the kind of dessert that brings joy to the simplest times. Cut it into wedges, serve it to your loved ones, and watch their faces light up with delight. Enjoy every decadent moment of this rich chocolate delight!

Can I use milk chocolate instead of dark chocolate for the mousse?
Yes, you can use milk chocolate instead of dark chocolate in your Dark Chocolate Mousse Cake for a sweeter flavor profile. However, keep in mind that this will alter the overall taste, creating a lighter and less intense chocolate experience. If you want to add depth while still using milk chocolate, consider incorporating a touch of espresso powder to enhance the flavor. Just be sure to adjust sugar levels to account for the sweetness of the milk chocolate.

To store your Dark Chocolate Mousse Cake, place it in an airtight container in the refrigerator. This cake maintains its best texture for up to three days. Avoid freezing the mousse, as it can lose its creamy consistency upon thawing. When ready to serve, simply slice and enjoy chilled. If you prefer a fresher presentation, consider adding a sprinkle of cocoa powder or a few fresh berries right before serving.
