Step-by-Step Instructions

Here’s how to make Nigella Chocolate Mousse Cake:

Prepare the Cake Layer:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease and line a 9-inch round cake pan with parchment paper.
2. Mix the Dry Ingredients: In a bowl, sift together the cake flour, baking powder, and powdered sugar. Set aside.
3. Whisk the Egg Yolks: In another bowl, whisk the egg yolks with the sugar until pale and fluffy.
4. Add Butter and Vanilla: Stir in the melted butter and vanilla extract into the egg mixture.
5. Combine Dry and Wet Ingredients: Gradually fold in the dry ingredients, mixing until just combined.
6. Whip the Egg Whites: In a separate bowl, whisk the egg whites until soft peaks form. Gently fold them into the cake batter, being careful not to deflate the mixture.
7. Bake the Cake: Pour the batter into the prepared cake pan and bake for about 25 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely.

Prepare the Chocolate Mousse:

8. Melt the Chocolate: Place the chopped dark chocolate in a heatproof bowl. Melt it using a double boiler or microwave in short intervals, stirring in between. Once melted, stir in the instant coffee, if using, and let it cool slightly.
9. Whip the Cream: In a separate bowl, whip the heavy cream until soft peaks form.
10. Beat the Egg Whites: In another bowl, beat the egg whites until soft peaks form.
11. Combine the Ingredients: Stir the cooled chocolate into the whipped cream. Gently fold in the egg whites, ensuring the mixture remains light and airy.
12. Layer the Cake and Mousse: Once the cake has completely cooled, place it on a serving platter. Spread the chocolate mousse over the cake, smoothing it into an even layer.
13. Chill the Cake: Cover the cake with plastic wrap and chill it in the fridge for at least 4 hours or overnight to allow the mousse to set.
