Why This White Christmas Mousse Cake Is the Ultimate Holiday Treat

The combination of flavors in this cake is what truly makes it special. The shortbread biscuit base adds a buttery, slightly crisp foundation that contrasts beautifully with the smooth, creamy mousse that sits on top. The addition of coconut in the base enhances the cake’s texture and brings a tropical touch that’s perfect for the festive season. The pistachios, both in the base and the mousse, provide a delightful crunch and earthy flavor that balances the sweetness of the white chocolate mousse. And let’s not forget the glace cherries scattered throughout the mousse, adding a touch of color and a burst of fruity sweetness.

The white chocolate mousse itself is velvety and rich, with just the right amount of sweetness. It’s light enough to keep you coming back for another bite, yet indulgent enough to satisfy your holiday cravings. The mousse is made even more decadent by the whipped cream incorporated into it, giving it a fluffy, melt-in-your-mouth texture. Topping the cake with whipped cream piped in elegant swirls, along with extra pistachios and cherries, creates a picture-perfect dessert that will steal the show at your holiday celebration.

A Breakdown of Ingredients: What You’ll Need to Make This Gorgeous Mousse Cake

This dessert uses only a few ingredients, but each one plays an important role in creating a delicious and well-balanced flavor profile. Here’s everything you’ll need to make the White Christmas Mousse Cake:

For the base:

• 135g shortbread biscuits – The shortbread adds a buttery, crisp texture to the cake, providing a solid foundation for the mousse layer.
• 1/4 cup shredded coconut – Coconut brings a light, tropical flavor and texture that complements the richness of the mousse.
• 1/2 cup pistachios – Pistachios add a delightful crunch and a mild nutty flavor that pairs perfectly with the white chocolate.
• 1 tablespoon pure icing sugar (sifted) – The icing sugar sweetens the base just enough without overpowering the other flavors.
• 75g unsalted butter, melted – The butter binds the ingredients of the base together and adds richness to the crust.

For the mousse:

• 2 teaspoons gelatine powder – Gelatine helps the mousse set and hold its shape.
• 2 tablespoons water – Used to hydrate the gelatine before incorporating it into the milk.
• 1/2 cup milk – The milk is heated and combined with the gelatine to dissolve it, creating the base for the mousse.
• 250g white chocolate, finely chopped – The star ingredient! The white chocolate is the key to the smooth and creamy texture of the mousse.
• 1 1/2 cups thickened cream – Cream gives the mousse its light, fluffy texture while adding a rich flavor.
• 75g glace cherries, chopped – Chopped cherries are folded into the mousse, providing a sweet and slightly tangy contrast to the rich mousse.
• Silver and gold cachous – These are optional but highly recommended for decorating the cake and adding a touch of sparkle and festivity to your holiday dessert.

Step-by-Step Instructions for Assembling the White Christmas Mousse Cake

Step 1: Prepare the Base

Start by preheating your oven to 180°C (or 160°C if using a fan-forced oven). Grease a 20cm springform cake pan and line the base and sides with baking paper to ensure easy removal once the cake is set. This step is crucial, as it allows you to remove the cake without worrying about it sticking to the pan.

In a food processor, combine the shortbread biscuits, shredded coconut, and 1/4 cup of the pistachios. Pulse until the mixture is finely ground into crumbs. Add the melted butter and sifted icing sugar to the mixture, then pulse again until everything is well combined. The mixture should resemble a dough-like consistency that holds together when pressed.

Now, press this mixture evenly into the base of your prepared cake pan. Use the back of a spoon or your hands to press it down firmly, ensuring an even layer. Bake the base in the preheated oven for 15 minutes, or until it turns light golden brown. Once baked, remove it from the oven and set it aside to cool completely.

Step 2: Prepare the Mousse

While the base cools, you can start preparing the mousse. Begin by sprinkling the gelatine over the water in a small bowl and allowing it to hydrate for a few minutes. In the meantime, heat the milk in a small saucepan over medium heat until it just starts to simmer. Remove the milk from the heat and stir in the hydrated gelatine, mixing until the gelatine is completely dissolved. Set the milk mixture aside to cool.

Next, place the finely chopped white chocolate in a large heatproof bowl. Pour the hot milk and gelatine mixture over the chocolate and let it sit for about 5 minutes. This resting time allows the chocolate to soften and melt from the heat of the milk. After 5 minutes, stir the mixture until it’s smooth and fully combined. Once the chocolate has melted completely, set the bowl aside to cool to room temperature.

Step 3: Whip the Cream and Combine

While the chocolate mixture cools, it’s time to whip the cream. Using an electric mixer or a whisk, beat the thickened cream until stiff peaks form. This will give your mousse a light, airy texture. Once the cream is whipped, fold it gently into the cooled white chocolate mixture in three separate batches. Take care not to deflate the cream as you fold it in. You should end up with a smooth and fluffy mousse.

Now it’s time to add the chopped pistachios and glace cherries. Gently fold them into the mousse mixture, being careful not to overwork it. The pistachios provide a delightful crunch, while the cherries add a burst of sweetness and a pop of color.

Step 4: Assemble the Cake

Once your mousse is ready, pour it over the cooled shortbread base in the cake pan. Use the back of a spoon to level the surface and smooth out the mousse. The mousse should fill the pan evenly and create a uniform surface. After this, cover the pan with plastic wrap and refrigerate the cake for at least 4 hours, or preferably overnight. The mousse needs time to set and firm up, so be patient as it chills in the fridge.

Step 5: Decorate and Serve

When you’re ready to serve, it’s time to add the finishing touches. In a separate bowl, whip the extra 300ml of cream until firm peaks form. Transfer the whipped cream to a piping bag fitted with a St. Honoré piping tip. Remove the mousse cake from the springform pan and transfer it to a serving plate.

Pipe the whipped cream in elegant swirls over the top third of the cake, creating a beautiful, textured design. Decorate the top with whole glace cherries, additional chopped pistachios, and a scattering of silver and gold cachous to give the cake a festive, sparkly finish.

The Perfect Holiday Dessert: Flavors, Textures, and Aromas

The White Christmas Mousse Cake is a sensory delight. From the moment you open the fridge and remove the cake, the rich aroma of white chocolate and the sweet scent of whipped cream fill the air. As you slice through the cake, the smoothness of the mousse contrasts perfectly with the crunchy base, making each bite a balance of textures. The flavor is equally balanced, with the white chocolate mousse offering just the right amount of sweetness, while the pistachios add a nutty flavor that complements the richness of the cream. The coconut in the base provides a subtle tropical touch, while the glace cherries add a burst of tangy sweetness, giving the dessert a festive, holiday-inspired twist.

The whipped cream topping is the crowning touch, adding an extra layer of indulgence and elegance. The decorative cachous bring a little sparkle, making the cake not only delicious but also a feast for the eyes.

Tips, Variations, and Substitutions to Make the Cake Your Own

• Gluten-Free Option: For a gluten-free version of this dessert, swap the shortbread biscuits for gluten-free biscuits or crushed gluten-free graham crackers. Ensure that all other ingredients, such as the cream and gelatine, are also gluten-free.
• Nut-Free Version: If you need to cater to guests with nut allergies, you can skip the pistachios in the base and mousse. Try using toasted sunflower seeds for crunch, or simply add more shredded coconut to enhance the texture.
• Dairy-Free: For a dairy-free alternative, use plant-based cream and dairy-free white chocolate. Be sure to check that the gelatine you use is also suitable for vegetarians if necessary.
• Flavor Variations: You can add a few drops of almond extract to the mousse for a slight nutty flavor, or swap the glace cherries for fresh raspberries for a fruitier option. Adding a touch of vanilla extract to the whipped cream will enhance the overall flavor.
• Serving Suggestions: This cake pairs beautifully with a warm cup of mulled wine or a glass of champagne. For a lighter option, serve it alongside fresh berries or a simple citrus salad to balance the sweetness of the mousse.
