Ingredients
For about 4–6 servings, you’ll need:
- 1 cup (240 ml) heavy whipping cream, cold
- 1/2 cup (120 ml) sweetened condensed milk
- 1/4 cup (60 ml) freshly squeezed lemon juice
- 1–2 teaspoons finely grated lemon zest
- 1 teaspoon vanilla extract
- 2 tablespoons powdered sugar, optional
- Lemon slices or extra zest, for decorating
A Quick Note About the Lemons
I strongly recommend using fresh lemons rather than bottled lemon juice. Fresh juice gives the mousse a much brighter, cleaner flavor, and the zest adds that lovely lemony aroma.
How to Make Lemon Mousse
1. Prepare the Lemon
Wash and dry your lemons well. Finely grate a little lemon zest, being careful to grate only the yellow outer skin and not the bitter white part underneath.
Then squeeze the lemons until you have about 1/4 cup of fresh lemon juice.
2. Make the Creamy Lemon Mixture
In a bowl, combine the condensed milk, fresh lemon juice, lemon zest, and vanilla extract.
Stir until everything is smooth and well combined.
You’ll notice the mixture begins to thicken slightly as the lemon juice mixes with the condensed milk. That’s exactly what you want.
3. Whip the Cream
Pour the cold heavy cream into a clean mixing bowl.
Whip it until you have soft to medium peaks. If you’re using powdered sugar, add it while whipping.
Don’t overbeat the cream. You want it fluffy and creamy rather than stiff and grainy.
4. Fold Everything Together
Add the lemon mixture to the whipped cream.
Using a spatula, gently fold everything together. Take your time with this step. You don’t want to stir aggressively because that can knock the air out of the whipped cream.
Keep folding until the mousse is evenly combined and beautifully creamy.
5. Chill
Spoon the lemon mousse into small glasses, dessert cups, or serving bowls.
Cover and refrigerate for at least 2 hours, although I usually prefer letting it chill for several hours for the best texture.
6. Decorate and Serve
Just before serving, add a little whipped cream, lemon zest, or a thin lemon slice on top.
That’s it!
A simple dessert that looks much more impressive than the effort required to make it.
Cooking Tips for Perfect Lemon Mousse
- Use cold cream. Cold heavy cream whips much more easily and gives you a fluffier mousse.
- Fresh lemon juice makes a difference. It gives the dessert a much more natural and vibrant flavor.
- Don’t over-whip the cream. Stop when you see soft or medium peaks.
- Fold gently. This is probably the most important tip for keeping your mousse light and airy.
- Taste before chilling. If you prefer a stronger lemon flavor, add a little extra zest or lemon juice.
- Give it enough chilling time. The mousse becomes firmer and more enjoyable after a couple of hours in the refrigerator.
- Use small serving glasses. Lemon mousse is rich enough that a modest portion feels just right.
Serving Suggestions
I usually serve this lemon mousse chilled straight from the refrigerator.
For a pretty finish, try topping each serving with:
- A little whipped cream
- Fresh lemon zest
- Thin lemon slices
- Fresh berries
- Crushed shortbread or digestive biscuits
- A small mint leaf
You can also make this dessert ahead of time. Prepare the mousse, cover the individual glasses, and keep them refrigerated until you’re ready to serve.

Frequently Asked Questions
1. Can I make lemon mousse ahead of time?
Absolutely. In fact, I usually prefer making it ahead. Keep the mousse covered in the refrigerator and serve it within about 2–3 days for the best texture and freshness.
2. Why is my lemon mousse too runny?
It may not have chilled long enough, or the cream may not have been whipped sufficiently. Make sure your cream is properly whipped before folding in the lemon mixture, and give the mousse at least a couple of hours in the refrigerator.
3. Can I use bottled lemon juice?
You can, but I recommend fresh lemon juice whenever possible. Fresh lemons give the mousse a much brighter flavor, especially when you add a little zest.
4. Can I make this dessert less sweet?
Yes. Since condensed milk is naturally sweet, you can’t completely remove the sweetness without changing the recipe, but you can balance it with additional fresh lemon zest and a little more lemon juice.
5. Can beginners make this lemon mousse?
Definitely! That’s one of the reasons I love this recipe. There are only a few basic steps, and there’s no baking involved. The main thing to remember is to whip the cream properly and fold the ingredients together gently.
Final Thoughts
I honestly think this easy lemon mousse is one of those recipes everyone should have in their dessert collection. It’s quick, creamy, refreshing, and simple enough for a beginner to make successfully.
The fresh lemon gives it just the right amount of brightness, while the creamy texture makes every spoonful feel like a treat. I especially love serving it in little glasses because it instantly makes the dessert look special.
