White Chocolate Mousse Cake Recipe |


  • 1 1/2 cups all-purpose flour
  • 1/2 tsp baking soda
  • pinch of salt
  • 1/4 cup butter (at room temperature)
  • 1 1/2 cup sugar
  • Three egg whites (from large eggs)
  • pinch of salt
  • 1 tsp vanilla extract
  • 1/3 cup milk
  • 3/4 cup white chocolate melts (or chocolate chips)
  • whipped cream or chocolate ganache, to serve (optional)


Steps 1:

Preheat oven to 350. In a bowl, sift the flour and baking soda together. Add a pinch of salt. Mix in a stand mixer (a hand whisk can also be used to do this) butter and sugar together until the mixture is pale and creamy, about 3-4 mins.

Steps 2:

Beat egg whites with a pinch of salt until stiff peaks form.

Steps 3:

Add the vanilla extract and milk to the butter mixture. Alternately add the flour and egg white mixtures to the butter mixture.

Steps 4:

Place parchment paper in a round baking tin (26cm). Use a spoon to spread and smooth the cake batter evenly over the pan.

Steps 5:

Bake for about 20-25 mins. Check with a wooden skewer; when inserted into the centre comes out clean, which means the cake is baked through. Leave to cool.

Steps 6:

Melt the white chocolate melts in a microwave-proof bowl. Microwave for 30 secs, stir until smooth and then return to the microwave for another 30 secs. Stir until the white chocolate is completely melted and smooth.

Steps 7:

Pour the melted white chocolate over the cake. Spread with a spatula or butter knife to cover it evenly. Let it set in the fridge for 20 mins before serving.

Steps 8:

Pipe whipped cream or spread with chocolate ganache over the cake before serving. You can also slice and eat it plain as it is.


1. If you don’t have any white chocolate melts, use chocolate chips and melt them in the microwave instead.

2. For a sweeter cake, add some desiccated or shredded coconut over the white chocolate mousse.  Snip out a corner of the parchment paper to make some small holes in the side of the cake so that the melted white chocolate can reach all parts of it.

3. Mix in some cocoa powder or instant coffee for a more intense flavour.

4. This cake can be frozen for up to 3-4 weeks. 

5. You can slice and eat the cake plain as it is.

Why is my chocolate mousse not fluffy?

The most common reason a chocolate mousse recipe is not fluffy is when your eggs are too cold or old. The eggs need to be at room temperature to mix smoothly with other ingredients.

Egg whites are also best if they have aged a few days before whipping them.  Please ask me if you have questions about this recipe in the comment section below. I will get back to you as soon as possible.

What are the four essential components of a mousse?

Chocolate mousse is made up of four essential components:

1. Egg Whites: This is the main ingredient of a chocolate mousse, because it gives the mousse its soft, airy texture and structure. Egg whites are also perfect for you and contain protein, vitamins and minerals.  You can use fresh or pasteurized egg whites when making a chocolate mousse.

2. Sugar or Sweetener: Most desserts require sugar or another sweetener to balance out their flavours. It’s also used for the structure of chocolate mousse.  Sugar also helps to prevent the curdling of egg whites.

3. Milk: Most chocolate mousse recipes call for milk because it is a critical ingredient that helps to make the mousse creamy and smooth in texture. It also helps to create a sweetening effect in the dessert. Starting with sugar and milk and adding egg whites should give you a light and fluffy chocolate mousse.
