Step‑by‑Step Instructions for Strawberry Mousse Cake
Step 1: Prepare the Sablé Crust
In a mixing bowl, combine 2 egg yolks with 50g of icing sugar and 75g of very soft salted butter, blending until smooth. Gradually add 120g of plain flour and mix until a dough forms. Press the dough evenly into the base of a lined cake ring, then chill in the refrigerator for 30 minutes. Preheat your oven to 160°C (325°F), bake the crust for 30 minutes, and let it cool completely.
Step 2: Make the Strawberry Mousse
For the luscious mousse layer of your Strawberry Mousse Cake, blend 375g of fresh or thawed strawberries until smooth. In a saucepan, simmer the blended strawberries with 90g of caster sugar and 1½ tsp of vanilla paste until fragrant. Bloom 7g of gelatine powder in 2 tbsp of cold water, then dissolve it in the warm strawberry mixture. Allow the mixture to cool until just set, and in a separate bowl, whip 400ml of chilled heavy cream to stiff peaks before gently folding it into the strawberry mixture.
Step 3: Assemble the Cake
Line the inside of your cake ring with an acetate strip to ensure easy removal later. Pour the prepared strawberry mousse over the cooled Sablé crust, smoothing the surface with a spatula. Cover with plastic wrap and refrigerate for at least 4 hours, or ideally overnight, until the mousse is set and firm to the touch.
Step 4: Prepare the Strawberry Jelly
To create the vibrant topping, blend another 200g of strawberries and strain the puree into a saucepan. Add 50g of caster sugar and 15ml of lemon juice, heating gently until the sugar dissolves. Bloom 3g of gelatine powder in a little water, then stir it into the warm strawberry mixture until completely dissolved. Let the jelly cool slightly before pouring it over the set mousse layer.
Step 5: Chill and Serve
Once poured, return the assembled Strawberry Mousse Cake to the refrigerator and chill for an additional 3 hours or overnight until the jelly is firm. When ready to serve, carefully remove the cake from the ring and acetate for a beautiful presentation. Enjoy this delightful Strawberry Mousse Cake chilled, showcasing its stunning layers.

Make Ahead Options
These Strawberry Mousse Cake preparations are fantastic for busy home cooks looking to save time while still serving a showstopper dessert! You can prepare the Sablé crust up to 24 hours in advance; simply bake it, let it cool, and store it in an airtight container at room temperature. For the mousse filling, you can blend the strawberries and mix it with the gelatine up to 3 days ahead; keep it refrigerated in a sealed container until you’re ready to fold in the whipped cream. When you’re prepared to serve, just assemble the mousse on the crust, refrigerate until set (ideally overnight), and add the jelly topping before serving. This way, you’ll enjoy a beautifully layered Strawberry Mousse Cake, just as delicious and fresh, with minimal effort on the day of your gathering!

Chill Time Matters: For best results, chill the mousse for at least 4 hours. This ensures it sets properly and achieves the perfect texture.

How to Store and Freeze Strawberry Mousse Cake

Freezer: Freezing is not recommended for this cake, as the delicate mousse and jelly layers do not retain their texture when thawed.
Make-Ahead: Consider making the cake a day in advance. This allows the flavors to meld beautifully while chilling overnight for the best results.
Reheating: If you have leftover mousse, it’s best enjoyed chilled directly from the fridge. Avoid reheating, as this can compromise its light and airy consistency.

Strawberry Mousse Cake Recipe FAQs
How do I select the best strawberries for my mousse?
Absolutely! Look for strawberries that are vibrant red, firm to the touch, and free from dark spots or bruises. When choosing strawberries, consider local options, as they tend to be fresher and sweeter. If using frozen strawberries, ensure they’re thawed completely before blending for the best flavor.
How should I store the Strawberry Mousse Cake?
The best way to store your Strawberry Mousse Cake is in an airtight container in the fridge for up to 3 days. This preserves its creamy texture and ensures it stays fresh. I often find that making it a day in advance allows the flavors to deepen, making it an ideal make-ahead dessert.
Can I freeze the Strawberry Mousse Cake?
Freezing is not recommended for this cake. The delicate mousse and jelly layers do not freeze well and lose their lovely texture once thawed. For optimal enjoyment, serve it fresh within 3 days of preparation, and save any extra mousse to enjoy directly from the fridge instead.
What should I do if the mousse doesn’t set properly?
If your mousse doesn’t set, the most likely culprit is the gelatine. Make sure it has been fully dissolved in the mixture before cooling it down. If you find that you’ve added too much liquid, consider re-whipping your cream to stiff peaks and gently folding it back into the mixture to help it achieve more body.
Can I make this dessert gluten-free?
Very! To make the Strawberry Mousse Cake gluten-free, simply substitute the plain flour in the Sablé Breton base with a gluten-free flour blend. Ensure that all other ingredients, especially your gelatine, don’t contain gluten. This way, everyone can enjoy a fresh slice of this delightful dessert.
Is this dessert suitable for people with allergies?
For those with allergies, it’s essential to note that this recipe contains eggs and dairy due to the Sablé crust and heavy cream in the mousse. If you have egg allergies, you can use an egg substitute for the yolks. As for dairy-free options, try using coconut cream or a plant-based heavy cream as alternatives, but keep in mind that this will slightly alter the flavor and texture.
