Ultimate chocolate mousse cake

Ingredients

  1. 225g plain chocolate (70% cocoa solids)
  2. 5 large free-range eggs, separated
  3. 150g golden caster sugar
  4. 125g unsalted butter, softened
  5. 50g ground almonds
  6. 4 tbsp Grand Marnier (optional)
  7. Rice paper daisies (optional), to decorate

For the mousse filling

  1. 142ml pot double cream
  2. 225g plain chocolate (70% cocoa solids)
  3. 4 large free-range eggs, separated

For the chocolate icing

  1. 200g plain chocolate (70% cocoa solids)
  2. 50g butter
  3. 2 tbsp icing sugar

Method

  1. 1. Preheat the oven to 180°C/fan 160°C/gas 4. Line the base of a 20cm springform cake tin with baking paper.
  2. 2. For the cake, put the chocolate in a small bowl set over a pan of gently simmering water and melt slowly. Take off the heat, stir until smooth and set aside to cool slightly.
  3. 3. Put the egg yolks and sugar in a bowl and beat with an electric whisk, until pale and thick. Keep whisking, adding the softened butter, a little at a time, then lower the whisk setting and whisk in the melted chocolate, then stir in the ground almonds.
  4. 4. In a clean bowl, whisk the egg whites to soft peaks. Beat a quarter of the egg whites into the chocolate mixture to loosen, then fold in the rest. Pour into the tin. Bake for about 45-50 minutes, until risen and firm but still a little moist in the centre when pierced with a skewer. Cool in the tin. When cool, remove and halve horizontally. Put the top layer, cut-side up, back in the tin and drizzle with half the liqueur, if using.
  5. 5. Make the mousse. Lightly whip the cream and set aside. Melt the chocolate over a pan of gently simmering water. Beat in the egg yolks, then fold in the cream. Whisk the egg whites in a bowl to soft peaks, then fold into the chocolate mixture. Spoon over the cake layer in the tin, spreading it to the edges.
  6. 6. Position the other cake layer cut-side down on top of the mousse and drizzle with the remaining liqueur, if using. Chill overnight.
  7. 7. Remove the cake from the tin and put on a plate. For the icing, melt the chocolate, butter and icing sugar in a bowl over a pan of gently simmering water. Spoon over the top of the cake and let it drip slightly over the edges. Decorate with the rice flowers, if using, and serve cut into wedges.

This luxurious dessert deserves a gorgeous Muscat. Beaumes-de-Venise would be the star choice.

The mousse kinda failed for me. In retrospect I should have whisked it within an inch of it's life or chilled it slightly before spooning on the cake as all I got was a runny-ish flat mixture which was reluctant to stay on the bottom layer. Never having made a mousse before a bit more explicit instructions would have been better. Otherwise the cake tastes fine, despite it's depressed appearance.

This cake took a long time to make, it tasted great but I left in the oven for 50 minutes as opposed to 45 and thought the filling could have been a little more moist so will take out earlier next time. I thought the daisies were very expensive, so made my own with a icing and a daisy cutter - VERY fiddly but looked really good!

This cake is meant to be very moist and fudgy. You may have 'over-folded' when you were adding the egg whites thereby knocking all the air out of the mixture - this stops the cake rising. Hope that helps. Regards, Debra, web editor

This took me a long time to make and was quite expensive. The cake was very flat when cooked and there was no way I could halve it as the recipe stated to get the mousse filling in between the two slices. Perhaps it was just me but it just didn't work.
