How to Make Strawberry Chocolate Mousse Cake
-
Preheat your oven to 350°F (175°C). Take a 9-inch round cake pan and grease it generously with cooking spray to ensure easy removal later.
-
Mix the crushed Oreos in a bowl with the melted butter and a pinch of kosher salt. Press this mixture tightly into the bottom of the prepared cake pan to form a sturdy crust.
-
Bloom the gelatin in cold water for about 5 minutes. Then, heat gently until dissolved, being careful not to boil it. This step ensures your mousse sets perfectly.
-
Melt the semisweet chocolate chips (2 1/4 cups) in a microwave-safe bowl, stirring every 30 seconds until completely smooth. Then, mix in the dissolved gelatin until well combined.
-
Whip 2 1/2 cups of heavy cream in a separate bowl until soft peaks form. Gently fold this whipped cream into the chocolate mixture, taking care not to deflate the airy texture.
-
Pour the luscious mousse over your Oreo crust and smooth the top with a spatula. Refrigerate for at least 6 hours or overnight until fully set.
-
Make the chocolate ganache by heating the remaining 1/2 cup of heavy cream until just simmering. Stir in the remaining 2 cups of melted semisweet chocolate until glossy and smooth.
-
Pour the ganache over the set mousse layer, allowing it to drizzle down the sides. If needed, chill briefly to firm up the ganache before topping. Finally, decorate with fresh strawberries and chocolate shavings for an exquisite touch.
Optional: Serve chilled slices garnished with extra berries for an elegant presentation.

How to Store and Freeze Strawberry Chocolate Mousse Cake
Fridge: Keep the cake covered in an airtight container for up to 3 days. This preserves its luscious mousse texture and flavor while preventing it from absorbing other odors.
Freezer: For longer storage, freeze slices wrapped tightly in plastic wrap followed by aluminum foil for up to 1 month. Thaw in the fridge overnight before serving to retain the delicate layers.
Reheating: If desired, serve the cake chilled directly from the fridge. Avoid reheating, as it can alter the mousse’s light texture.

Expert Tips for Strawberry Chocolate Mousse Cake
• Make Ahead Magic: Prepare your Strawberry Chocolate Mousse Cake a day in advance for the best setting and flavor development.
• Chill the Cream: Ensure your heavy cream is as cold as possible before whipping; this will help achieve soft peaks and a light mousse.
• Gentle Folding: When combining the whipped cream with the chocolate mixture, fold gently to retain air, maintaining that fluffy texture crucial for the mousse.
• Perfect Gelatin Usage: Bloom the gelatin thoroughly; incomplete blooming can lead to a runny mousse. Ensure it dissolves completely before mixing with chocolate.
• Watch the Ganache: Allow your chocolate ganache to cool slightly before pouring over the set mousse; this prevents melting the mousse underneath.
• Experiment with Flavors: Don’t hesitate to swap strawberries for raspberries or different chocolate types in your Strawberry Chocolate Mousse Cake for unique twists!
Strawberry Chocolate Mousse Cake Recipe FAQs
How do I select the right strawberries for my cake?
Absolutely! Look for strawberries that are bright red with a natural shine, and avoid any with dark spots or bruising. The best choices are firm, juicy berries that smell sweet. If possible, choose organic strawberries as they tend to have better flavor and are free from pesticides.
How should I store my Strawberry Chocolate Mousse Cake?
Very! Store the cake in an airtight container in the refrigerator for up to 3 days. Ensure it’s well-covered to avoid absorbing any odors from other foods. If you’re making it ahead of time, this cake can stay fresh and delightful when prepared a day in advance!
Can I freeze the Strawberry Chocolate Mousse Cake?
Absolutely! To freeze, slice the cake and wrap each piece tightly in plastic wrap followed by aluminum foil. It can be stored like this for up to 1 month. When you’re ready to enjoy it, thaw the slices in the fridge overnight; this helps retain the mousse’s beautiful texture and flavor.
What if my mousse isn’t setting properly?
No worries! If the mousse isn’t setting, it might be due to the gelatin not blooming correctly. Make sure to bloom the gelatin in cold water for about 5 minutes before gently heating it to dissolve fully. If it’s already mixed and not firming up, you can try rewhipping some heavy cream and folding it back in before letting it set again.
Are there any dietary considerations for my guests?
Certainly! If you have guests with allergies, be mindful of the ingredients. The mousse cake contains dairy and gluten from the Oreos. You can easily swap Oreos for a gluten-free alternative, and use dairy-free chocolate and cream for a dairy-free version. Always check ingredient labels, as some chocolates may contain allergens.
Can I use other types of chocolate in my mousse?
Absolutely! While this recipe features semisweet chocolate, you can experiment with bittersweet, dark, or even white chocolate for a unique flavor twist. Just remember that using a different type might alter the sweetness, so adjust your powdered sugar accordingly!
