Why we love this recipe
These whipped vanilla mousse cups are elegant and surprisingly easy. The base is a sweetened vanilla custard combined with softly whipped cream, creating a mousse that is delicately light while still offering a rich vanilla taste. No gelatin is required for the classic soft texture, though a small amount can be added if you prefer a firmer set. Versatile and quick to prepare, the mousse pairs well with many toppings and makes a refined finish to any meal.
What is a mousse
The French word “mousse” means foam or froth. In desserts, a mousse is made by folding an aerated component (whipped cream or whipped egg whites) into a flavored base such as pastry cream, fruit purée, or melted chocolate. The air trapped in the mixture gives mousse its characteristic light, airy texture. Mousses are commonly served individually in cups, layered into trifles, or used as fillings for cakes and tarts.

Key components:
- Cream: Use thickened or heavy whipping cream with at least 35% fat so whipped cream holds its structure.
- Vanilla: Fresh vanilla bean delivers the best flavor and visual vanilla specks. Vanilla paste is a good alternative; extract will work but with a milder result.
- Eggs: Whole large eggs at room temperature are used in the custard base. Room temperature eggs temper more gently when combined with warm cream.
- Sugar: Caster or superfine sugar dissolves quickly; granulated sugar is an acceptable substitute.
- Cornstarch: Thickens the custard. You can substitute all-purpose flour, tapioca starch, or arrowroot if preferred.
How to make Vanilla Mousse Cups

Note: the method below reflects the updated process to ensure the mousse sets reliably.
1. Prepare the vanilla-infused cream: pour the first portion of cream into a medium saucepan. Split the vanilla bean lengthwise and scrape out the seeds; add both the seeds and the pod to the cream. Warm gently over low heat until it just begins to simmer, then remove from heat and cover. Let the cream infuse for 10–15 minutes. Do not boil the cream.
2. Mix eggs and sugar: in a large bowl, whisk the room-temperature eggs with the sugar until combined. Add the cornstarch and stir until smooth.
3. Temper the eggs: remove the vanilla pod from the warmed cream. Slowly pour a small stream of hot cream into the egg mixture while whisking constantly to raise the temperature gradually. Continue until all the cream is incorporated and the mixture is smooth.

4. Cook the custard: return the combined mixture to the saucepan and cook over low heat, stirring constantly, until the custard thickens and coats the back of a spoon. Maintain a gentle heat to avoid overcooking; the custard should not boil. If you have a thermometer, aim for about 82–84°C (180–183°F).
5. Chill the custard: transfer the custard to a clean bowl, press plastic wrap directly onto its surface to prevent a skin forming, and refrigerate for 1–2 hours or until completely cool.
6. Whip the remaining cream: whip the second portion of cream on medium to medium-high speed until medium to stiff peaks form. Stop whipping slightly earlier for a softer mousse, or continue to stiff peaks for a firmer texture.
7. Fold and set: gently loosen the chilled custard with a light whisk. Fold the whipped cream into the custard in three to four additions, using a spatula and gentle strokes to preserve air. When combined, divide the mousse among serving cups and refrigerate for at least 3 hours, ideally overnight, until fully set.
8. Serve: garnish with fresh berries, a fruit coulis, chocolate shavings, or a crumb base before serving.

Recipe FAQs
Why is mousse called mousse?
The term comes from the French “mousse,” meaning foam or froth, which describes the airy, bubble-filled texture created by whipping in air.
How is mousse different from whipped cream?
Whipped cream is simply aerated cream. A mousse combines a flavored base—such as a custard, purée, or melted chocolate—with whipped cream or whipped egg whites, giving it a more complex flavor and often a denser, creamier mouthfeel.
Can I use vanilla extract or paste?
Fresh vanilla beans or vanilla paste deliver the best flavor and the characteristic specks. Vanilla extract works in a pinch but yields a less intense flavor.
Can I use this mousse as a cake filling?
This recipe produces a soft mousse that may be too loose for tall layer cakes. For a more stable filling, fold in a little gelatin or use the mousse between sturdier cake layers and refrigerate thoroughly before serving.

Tips & Troubleshooting
- How to know the custard is cooked: the custard should coat the back of a spoon and allow a clear line to be drawn through it. If using a thermometer, target 82–84°C (180–183°F).
- Lumpy or curdled custard: high heat can scramble the eggs. If small lumps appear, pass the custard through a fine mesh sieve or briefly blend with an immersion blender to smooth it.
- Mousse not setting: incorrect whipping of the cream—either under- or over-whipping—can prevent a proper set. Also allow sufficient chilling time, preferably overnight.
Serving Suggestions
Serve the mousse plain or topped with fruit coulis, fresh compote, curd, chocolate sauce, or grated chocolate. A crumb base of cookies or a thin sponge layer works well for individual, jarred desserts or trifles.
Topping ideas: fruit coulis (raspberry, strawberry, blueberry, mango, passion fruit), fruit compotes, curds (lemon, orange, passion fruit), or chocolate shavings. Base ideas: crushed cookies (Biscoff, graham crackers, sablés) or a thin sponge layer.
Storing & Freezing
Store mousse cups covered in the refrigerator and consume within two days for best texture and flavor. Do not freeze; freezing changes the delicate texture and may cause separation.

Recipe
Ingredients
- 240 ml thickened cream / heavy whipping cream (part 1), min. 35% fat
- 1 fresh vanilla bean pod (or 2 tsp vanilla paste)
- 40 g caster sugar
- 2 large eggs, room temperature
- 8 g (1 tbsp) cornstarch
- 360 ml thickened cream / heavy whipping cream (part 2), min. 35% fat
Instructions
- Pour the first part of the cream into a saucepan. Split the vanilla bean and scrape the seeds into the cream. Add the pod, heat until just simmering, then cover and infuse for 10–15 minutes.
- Whisk eggs and sugar in a large bowl, then mix in the cornstarch until smooth.
- Remove the vanilla pod, then slowly pour the warm cream into the egg mixture while whisking to temper the eggs.
- Return the mixture to the saucepan and cook gently, stirring constantly, until it thickens and coats the back of a spoon. Do not boil.
- Transfer the custard to a bowl, press plastic wrap on the surface, and chill for 1–2 hours until cold.
- Whip the remaining cream to medium or stiff peaks, depending on desired texture.
- Fold the whipped cream into the chilled custard in 3–4 additions, gently combining to keep the mixture airy.
- Divide into serving cups and refrigerate at least 3 hours or overnight. Garnish before serving.
Notes
- Reserve the used vanilla pod to make homemade extract.
- Tempering the eggs prevents curdling when combining with hot liquid.
- The cooked custard should reach about 82–84°C (180–183°F) or coat the back of a spoon.
- It is safer to under-whip the cream slightly; over-whipping can make folding difficult and lead to a less smooth mousse.
