White Christmas Mousse Cake Ingredients
For the Crust
- Shortbread biscuits – Perfect for a sweet and crumbly base; graham crackers can be used for a different flavor.
- Shredded coconut – Adds a delightful chew; can be omitted for a nut-free alternative.
- Pistachios – Provides wonderful crunch and visual appeal; almonds or walnuts can also work well.
- Pure icing sugar – Sweetness for the crust; granulated sugar is a feasible substitute but may change the texture.
- Unsalted butter – Binds the crust ingredients together; melted coconut oil offers a dairy-free option.
For the Mousse
- Gelatine powder – Crucial for setting the mousse; agar-agar is a great vegetarian substitute.
- Water – Activates the gelatine, essential for the mousse consistency.
- Milk – Adds creaminess to the mousse; almond or oat milk can replace it for a lactose-free version.
- White chocolate – The main flavor source of the mousse; dark chocolate provides a different yet delicious twist.
- Thickened cream – Creates that rich, velvety mousse texture; whipped coconut cream can be used as a non-dairy substitute.
For the Decoration
- Glace cherries – Beautifully used in the mousse and as a topping; feel free to substitute with fresh cherries or other berries.
- Silver and gold cachous – Adds a glamorous festive touch to your presentation.
How to Make White Christmas Mousse Cake
-
Preheat oven: Begin by preheating your oven to 180°C (or 160°C fan-forced) and greasing a 20cm springform cake pan. Line the bottom with baking paper for easy removal later.
-
Make the crust: In a food processor, blend shortbread biscuits, shredded coconut, and 1/4 cup of pistachios until fine crumbs form. Add melted unsalted butter and icing sugar, pulse to combine, and firmly press the mixture into the base of your pan.
-
Bake the crust: Place the crust in the oven and bake for about 15 minutes or until it turns lightly golden. Allow it to cool completely before adding the mousse layer.
-
Prepare gelatine: In a small bowl, hydrate the gelatine powder in water. Meanwhile, heat the milk in a saucepan until it just begins to simmer. Remove from heat and stir in the gelatine until it dissolves completely.
-
Combine chocolate and milk: Pour the hot milk mixture over the chopped white chocolate in a separate bowl. Let it sit for 5 minutes, then stir until smooth and completely cool.
-
Whip the cream: In another bowl, whip the thickened cream to firm peaks. Fold this whipped cream gently into the cooled chocolate mixture in batches, being careful not to deflate the airy texture.
-
Add fruits: Once incorporated, fold in the remaining chopped pistachios and the glace cherries to the mixture for added flavor and color.
-
Assemble the mousse cake: Pour the mousse mixture over the cooled crust in the pan. Smooth the top gently, cover with plastic wrap, and refrigerate for at least 4 hours or ideally overnight until the mousse is fully set.
-
Decorate: Just before serving, whip additional cream and decorate the mousse cake as desired with piping, cherries, and a sprinkle of cachous for that festive flair.
Optional: Add a sprinkle of crushed pistachios on top for extra crunch and color.

Can I freeze the mousse cake?
Absolutely! To freeze your White Christmas mousse cake, slice it and place the pieces in an airtight container. It can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw it in the refrigerator overnight and serve. Perfect for those busy holiday parties!
How do I know if my mousse is set properly?
The mousse is fully set when it feels firm to the touch and holds its shape without wobbling. It typically requires at least 4 hours in the refrigerator, but I often recommend letting it sit overnight for the best results. This ensures every slice is perfect and prevents any collapsing when you serve!
Can I make this cake dairy-free?
Definitely! To make a dairy-free White Christmas mousse cake, substitute the thickened cream with whipped coconut cream. You can also replace milk with almond or oat milk. The chocolate can still shine through, maintaining its delicious flavor profile while adhering to dietary preferences.
What should I do if the gelatine doesn’t dissolve properly?
If your gelatine doesn’t dissolve, it might be because it didn’t hydrate fully. Make sure you let the gelatine sit in water for about 5-10 minutes before heating it with the milk. If you still have clumps, you can strain the mixture before adding it to the chocolate to ensure a smooth mousse texture.
