Ingredients
• 3 large ripe bananas, mashed – 13.4 oz / 380g
• 2 cups heavy whipping cream – 16 fl oz / 473ml
• 3 tbsp powdered sugar – 0.9 oz / 25g
• 2 tbsp fresh lemon juice – 1 fl oz / 30ml

3. Add Sweetener: Gently whip in the powdered sugar until just combined and soft peaks form. Be careful not to overmix.
4. Combine Gently: Add the banana purée to the whipped cream. Using a spatula, gently fold the two mixtures together until just combined, being careful not to deflate the cream.

Pro Tips
• for the Best Mousse
• For the fluffiest mousse, chill your mixing bowl and beaters for 15 minutes before starting. Cold tools help the cream whip up with more volume.
• Use very ripe bananas with plenty of brown spots. They are naturally sweeter, providing a deeper flavor, and purée into a smoother consistency.
• Gently fold the banana purée into the whipped cream with a spatula—do not stir. This preserves the air bubbles and keeps the mousse from becoming dense.
FAQ
Q: Can I make this banana mousse vegan
A: Yes, to make this recipe vegan, substitute the heavy whipping cream with a high-quality, full-fat coconut cream. Chill the can overnight, then scoop out the solid cream from the top and whip it just as you would dairy cream for a delicious, plant-based alternative.
Q: Is there a vegetarian-friendly substitute for the rum
A: Absolutely. The rum is optional and can be omitted entirely. For a similar flavor profile without alcohol, you can substitute it with 1/2 teaspoon (10 ml / 0.3 fl oz) of rum extract or vanilla extract. This will still provide a lovely warmth and depth to the mousse.
Q: How long can I store this vegetarian banana mousse
A: This mousse is best enjoyed within 24-48 hours. Store it covered in the refrigerator. After two days, the whipped cream may begin to lose its airy texture and the banana flavor will become more pronounced, so it’s freshest when served soon after chilling.
Q: Is this eggless banana mousse recipe healthy
A: This recipe is a treat, but you can make adjustments. It’s naturally vegetarian and egg-free. For a lower-sugar version, you can reduce the powdered sugar or substitute it with a natural sweetener like maple syrup to taste, keeping in mind it may slightly change the texture.
Pro Tips
- For the fluffiest mousse, chill your mixing bowl and whisk before you start, cold cream whips higher and holds its structure longer.
- Use very ripe bananas with plenty of brown spots, they blend into a smoother purée and bring the deep banana flavor this dessert is built on.
- Gently fold the banana purée into the whipped cream with a light hand, stirring too vigorously knocks out the air you just whipped in.
- The fresh lemon juice keeps the banana from browning and lifts the flavor, so add it straight into the purée before it meets the cream.
Frequently Asked Questions
How far ahead can I make this banana mousse?
Make it up to a day ahead and keep it covered in the fridge. The texture stays fluffy for about 24 hours, after that it slowly relaxes but still tastes wonderful.
Can I leave out the rum?
Yes, the dark or spiced rum is a background note that rounds out the banana flavor, and the mousse sets perfectly without it.
Is this dessert vegetarian?
Yes, it is a vegetarian dessert made with cream and banana, and it requires no baking at all, which makes it ideal for warm days.
Why is my mousse runny?
Usually the cream was underwhipped or the banana purée was added while still warm. Whip to soft peaks, fold gently, and chill the full time before serving.
