Lemon Mousse Recipe: Easy 3-Ingredient Thermomix Dessert 2026

This lemon mousse is proof that a spectacular dessert doesn't need a long ingredient list or hours in the kitchen. With just three ingredients and a Thermomix, you get a creamy, refreshing mousse that's ready in about five minutes, plus chilling time. It's the kind of dessert that looks and tastes far more complicated than it actually is.

Because it's served in individual glasses, it works beautifully as a light finish to a big meal. The hardest part is waiting for it to firm up in the fridge, but that patience pays off with a perfectly smooth, tangy-sweet texture.

Ingredients for Lemon Mousse

This recipe makes 4 servings and comes together with just three ingredients.

• 350 g sweetened condensed milk
• 250 g cold heavy whipping cream
• 120 ml lemon juice

How to Make Lemon Mousse Step by Step

1. Mix the Ingredients in the Thermomix

Place the butterfly attachment in the Thermomix bowl and pour in 350 g of sweetened condensed milk, 250 g of cold heavy whipping cream and 120 ml of lemon juice. Mix for 1 minute and 30 seconds at speed 4, until everything is fully combined and slightly thickened.

2. Divide and Chill

Divide the mousse among individual glasses or small cups and let it rest in the refrigerator for at least 4 hours, until it sets and reaches a firm, creamy consistency.

3. Decorate and Serve

Decorate each mousse with a thin slice of lemon, dark chocolate shavings or crushed cookie crumbs, then serve well chilled.

Tips for the Best Lemon Mousse

Use Cold Cream

The cream must be thoroughly chilled before you start, straight from the fridge. Cold cream whips and thickens much better, giving the mousse its light, airy body.

Don't Skip the Chilling Time

Four hours in the refrigerator is the minimum for the mousse to set properly. If you can, leave it overnight for an even firmer, silkier result.

Get Creative with Toppings

A lemon slice, dark chocolate shavings or crushed cookies all work wonderfully as decorations. Feel free to mix and match to suit the occasion.
