This Banana Mousse Recipe produces a light, set dessert that works well after a heavy meal or as a standalone sweet. Ripe bananas are puréed with lemon and orange juice and sugar, then combined with dissolved gelatin warmed in crème de banane liqueur. Lightly whipped cream is folded in last, which keeps the texture airy without making it dense. The mousse is then spooned into bowls and refrigerated until firm. There is no baking involved, the preparation is straightforward, and the outcome depends mostly on two things: using bananas that are properly ripe and being careful with the gelatin quantity.
About the Recipe
The recipe calls for 250g of ripe bananas, which blend more smoothly and taste noticeably sweeter than underripe ones. Lemon and orange juice add brightness and help slow browning. Crème de banane liqueur is used to warm and dissolve the gelatin leaves, which means the alcohol does double duty here. The cream is whisked until thick but not fully whipped before folding in, so it incorporates without deflating. The gelatin quantity matters a great deal. Too much and the mousse sets firm like a jelly. The note in the recipe is worth taking seriously.
Why You Will Love This Recipe
The texture is the main reason to make this. Because the cream is only partially whipped before folding in, the mousse stays soft and spoonable after setting rather than turning stiff. It holds its shape cleanly when served but gives way easily. The second reason is that the preparation itself is genuinely quick. The bananas go straight into a mixie or food processor with the sugar and juices, the gelatin is dissolved in warmed liqueur off the heat, and everything is combined before the cream is folded through. There is no cooking beyond warming the liquid, and the refrigerator does the rest.
Cooking Tips
The most common beginner mistake with this recipe is using too much gelatin. Measure carefully and follow the quantity given. Dissolve the gelatin away from direct heat after warming the crème de banane and water, not over a flame, or it may not set evenly. Whisk the cream only until thick and just holding shape. Fully whipped cream will make the mousse heavier than it should be. Use bananas that are well ripened with visible browning on the skin for the best flavour and smoothest purée.
Top Tips
- Use bananas with brown-spotted skins. They purée more smoothly and taste sweeter than yellow or underripe ones.
- Dissolve the gelatin away from direct heat. Stir it into the warmed crème de banane and water after removing the pan from the heat.
- Stop whisking the cream once it is thick and just holding soft peaks. Over-whipped cream will make the mousse dense.
- Add the gelatin mixture to the banana purée while both are still at room temperature. If the purée is cold, the gelatin may begin to set unevenly before the cream is folded in.
- Do not increase the gelatin quantity hoping for a firmer result. The mousse is meant to be soft and delicate, not jelly-like.
Serving and Storing Suggestions
Spoon the mousse into individual serving bowls before refrigerating so it is ready to serve without disturbing the set texture. A single large bowl works if you are serving at the table and spooning portions out. Serve cold, straight from the refrigerator. Cover the bowls with cling film if storing overnight. The mousse is best eaten within two days. A few thin banana slices or a light dusting of caster sugar on top are enough as a garnish if needed.

Nutrient Benefits
Ripe bananas provide potassium and some natural sugars, as well as small amounts of vitamin B6 and vitamin C. The orange and lemon juice in this recipe add further vitamin C. Cream contributes fat-soluble vitamins A and D. This is a dessert, so the sugar and cream content is notable, but the banana base does bring genuine nutritional value alongside the sweetness.

Frequently Asked Questions
Can I make this banana mousse recipe without crème de banane liqueur?
The crème de banane is used primarily as the liquid to warm and dissolve the gelatin. If you prefer to leave it out, you can use an extra tablespoon of water in its place. The mousse will taste less intensely of banana liqueur, but the texture and set will not be affected as long as the gelatin dissolves fully.
What happens if I use too much gelatin?
The mousse will set firm and rubbery rather than soft and spoonable. The recipe note flags this specifically. Measure the gelatin carefully, either 3 leaves or 1½ tablespoons of powdered gelatin, and do not be tempted to add more thinking it will produce a better result. A mousse is meant to be delicate, not stiff.
Can I use powdered gelatin instead of gelatin leaves?
Yes. The recipe gives both options. Use 1½ tablespoons of powdered gelatin as a direct substitute for 3 gelatin leaves. Soak it in cold water for 10 minutes before using, then squeeze out excess water if using leaves, or drain carefully if using powder. Dissolve it in the warmed crème de banane and water mixture away from direct heat.
How ripe should the bananas be for this recipe?
Use bananas that are well ripened, meaning the skin has visible brown spots or patches. At this stage they are softer, sweeter, and will purée more smoothly in a mixie or food processor. Underripe or just-yellow bananas will not purée as cleanly and the flavour will be noticeably less sweet and less fragrant in the finished mousse.
How long does the mousse take to set in the refrigerator?
Allow at least 2 to 3 hours of refrigeration for the mousse to set properly. If you are making it for a meal, preparing it several hours ahead or the evening before works well. Once set, keep it covered with cling film and consume within two days for the best texture and taste.
