This heavenly dessert proves that the most impressive treats often come from the simplest ingredients, creating a mousse so divine it will become your go-to dessert for any occasion.
Why This Banana Mousse is So Special
Italian desserts are renowned for their perfect balance of flavors and textures, and this banana mousse exemplifies that tradition beautifully. The secret lies in gently caramelizing the bananas to intensify their natural sweetness and create depth of flavor, then combining them with a silky custard base and whipped cream. The result is a dessert that’s both elegant enough for dinner parties and simple enough for everyday indulgence.
Ingredients
For the Caramelized Banana Base:
- 3 ripe bananas (approximately 350g/12.3 oz)
- 30g (2 tablespoons) unsalted butter
For the Custard Base:
- 250ml (1 cup) whole milk
- 40g (1/3 cup) cornstarch
For the Mousse:
- 250ml (1 cup) heavy cream
- 150g (2/3 cup) sweetened condensed milk
Optional Garnishes:
- Fresh banana slices
- Mint leaves
- Chopped nuts
- Dark chocolate shavings
Step-by-Step Instructions
Preparing the Caramelized Bananas
Step 1: Prepare the Bananas Peel the bananas and slice them into rounds approximately 1cm (½ inch) thick. Choose bananas that are ripe but still firm, as they’ll hold their shape better during cooking while providing optimal sweetness.
Step 2: Caramelize the Bananas Heat the butter in a medium non-stick pan over low heat until melted and foaming. Add the banana slices in a single layer, ensuring they don’t overlap. Cook gently for 10 minutes, turning once halfway through, until the bananas are golden brown and caramelized on both sides. The slow cooking process concentrates the banana flavor and creates natural caramel notes.
Step 3: Cool and Mash Remove the caramelized bananas from heat and let them cool for 5 minutes. Using a fork or potato masher, mash the bananas until smooth but with some small chunks remaining for texture. The mixture should be fragrant and deeply flavored from the caramelization process.
Creating the Custard Base
Step 4: Prepare the Cornstarch Mixture In a small bowl, whisk together the cornstarch with 3-4 tablespoons of the cold milk until completely smooth and no lumps remain. This slurry will prevent the cornstarch from clumping when added to the hot milk.
Step 5: Heat the Milk Pour the remaining milk into a medium saucepan and heat over medium heat until it begins to steam and small bubbles form around the edges. Do not let it boil, as this can cause the milk to scorch.
Step 6: Thicken the Custard Gradually whisk the cornstarch mixture into the hot milk, whisking constantly to prevent lumps. Continue cooking over medium heat, stirring continuously, for 3-5 minutes until the mixture thickens to a custard-like consistency that coats the back of a spoon.
Step 7: Cool the Custard Remove the thickened custard from heat and let it cool to room temperature, stirring occasionally to prevent a skin from forming on top. For faster cooling, place the saucepan in an ice bath while stirring.
Assembling the Mousse
Step 8: Combine Banana and Custard Once the custard has cooled, fold in the mashed caramelized bananas until well combined. The mixture should be smooth and aromatic, with the banana flavor beautifully integrated throughout.
Step 9: Prepare the Cream In a large mixing bowl, combine the heavy cream and sweetened condensed milk. Using an electric mixer or whisk, beat the mixture until it forms soft peaks. Be careful not to overwhip, as this can cause the cream to become grainy.
Step 10: Fold Together Gently fold the banana-custard mixture into the whipped cream using a large spoon or spatula. Use a folding motion rather than stirring to maintain the mousse’s light, airy texture. Fold until just combined and no streaks remain.
Final Assembly and Serving
Step 11: Portion the Mousse Divide the mousse among serving glasses, ramekins, or dessert cups. For an elegant presentation, use a piping bag fitted with a star tip to pipe the mousse in decorative swirls.
Step 12: Chill and Set Refrigerate the mousse for at least 30 minutes to allow it to set properly, though it can be enjoyed immediately if desired. For best results, chill for 2-4 hours to achieve the perfect creamy consistency.

Serving Suggestions and Presentation
This elegant mousse can be served in various ways depending on the occasion. For casual dining, serve in simple glasses with a sprinkle of cinnamon. For formal dinners, present in crystal glasses with fresh fruit garnishes and mint leaves. The mousse also works beautifully as a filling for pastry shells or as a component in layered desserts.
Storage and Make-Ahead Tips
The mousse can be prepared up to 24 hours in advance and stored covered in the refrigerator. In fact, longer chilling time often improves the flavor as it allows all the components to meld together beautifully. For longer storage, the mousse can be frozen for up to one month, though the texture will be slightly different when thawed.
Professional Tips for Perfect Mousse
The key to achieving restaurant-quality mousse lies in temperature control and gentle folding techniques. Ensure all components are at the proper temperature before combining, and fold ingredients together slowly to maintain the dessert’s signature light texture. The caramelization step is crucial for developing deep banana flavor that sets this mousse apart from simpler versions.
Frequently Asked Questions
Can I use overripe bananas for this recipe? While overripe bananas are sweeter, they can become mushy during caramelization. Choose bananas that are ripe but still hold their shape when cooked. If using very ripe bananas, reduce the cooking time to prevent them from becoming too soft.
What if I don’t have cornstarch? You can substitute cornstarch with an equal amount of all-purpose flour, though the texture will be slightly different. Alternatively, use instant pudding mix for a quicker custard base, adjusting the milk quantity according to package directions.
How can I tell when the custard is thick enough? The custard is ready when it coats the back of a spoon and doesn’t immediately run off. You should be able to draw a line through the custard on the spoon with your finger, and it should hold its shape momentarily.
Can I make this mousse without the custard base? While the custard adds stability and richness, you can create a simpler version by folding the mashed caramelized bananas directly into the whipped cream mixture. The result will be lighter but less stable.
Why is my mousse too runny? A runny mousse usually results from under-whipped cream or insufficient chilling time. Ensure the cream forms soft peaks before folding, and allow adequate refrigeration time for the mousse to set properly.
