Ingredients You’ll Need
For the Base
- 1 ½ cups crushed chocolate biscuits (or graham crackers with cocoa)
- 5 tbsp melted butter
- 1 tbsp cocoa powder (optional, for deeper flavor)
For the Chocolate Mousse Layer
- 1 ½ cups heavy cream (cold)
- 200 g milk chocolate or semi-sweet chocolate (melted and cooled)
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
Optional Toppings
- Chocolate shavings
- Cocoa powder
- Whipped cream
- Fresh berries
How to Make No-Bake Chocolate Mousse Cake
1. Prepare the Base
Start by combining crushed chocolate cookies with melted butter until the texture resembles wet sand. Press this mixture firmly into the bottom of a lined cake pan. Use the back of a spoon or a flat cup to make the base as even as possible.
Refrigerate for 15–20 minutes while you prepare the mousse layer.
2. Make the Chocolate Mousse
Whip the cold heavy cream with powdered sugar and vanilla extract until it forms stiff peaks.
Melt your chocolate using a double-boiler method or microwave in 20-second intervals. Let it cool slightly so it doesn’t melt the whipped cream.
Gently fold the melted chocolate into the whipped cream until smooth and airy. Take your time to avoid deflating the mousse.
3. Assemble the Cake
Pour the mousse mixture over the chilled base. Smooth the top with a spatula for a clean finish.
Refrigerate for at least 4 hours, or overnight for the best texture.
4. Add the Final Touch
Once set, dust the cake with cocoa powder or add chocolate shavings on top. Slice with a warm knife for clean cuts.
Tips for a Perfect No-Bake Mousse Cake
Use cold cream for the fluffiest mousse
The colder the heavy cream, the better it will whip and hold its shape.
Cool the melted chocolate
Warm chocolate can deflate the mousse or create grainy texture. Let it cool to room temperature before folding.
Refrigerate long enough
The mousse needs time to set fully. Overnight chilling guarantees a firm, sliceable cake.
Choose quality chocolate
Because this cake has minimal ingredients, the chocolate flavor shines through. Use a brand you enjoy eating.
Variations You Can Try
This recipe is incredibly versatile. Here are some fun ideas to switch things up:
1. Dark Chocolate Version
Use 70% dark chocolate for a more intense and less sweet flavor.
2. Oreo Base
Replace biscuits with crushed Oreos—including the cream—for a richer base.
3. Nutty Crunch
Add chopped hazelnuts or almonds into the base or sprinkle on top.
4. White Chocolate Mousse Cake
Swap milk chocolate for white chocolate and add berries for a fruity version.
5. Mocha Mousse Cake
Add a teaspoon of instant espresso powder to the melted chocolate for a coffee-infused twist.
