The sweet scent of blended strawberries — something between candy and just-picked fruit — rises from the first seconds. This dessert is nothing spectacular to prepare: no oven, no saucepan, just a blender and a spatula. But the result in the glass, light and pink, has a way of pleasing everyone effortlessly.
The mousse barely holds itself, pink and quivering. You can smell the strawberries before even plunging the spoon in. And then there’s the speculoos — that crunchy, caramelized resistance that contrasts with the lightness of the fruit, slightly spicy, slightly sweet. In the mouth, it’s airy without being bland, fruity without being acidic.

Ingredient Notes
250 g ripe strawberries, speculoos, sugar, vanilla sugar and one egg white: that’s all you need.
- Strawberries (250 g) : Choose them very ripe and fragrant — seasonal strawberries, the ones that stain your fingers as soon as you cut them, give a mousse with a different color and taste than supermarket strawberries in January. The sweeter they are naturally, the less you’ll need to adjust with sugar.
- Speculoos : A few cookies are enough, no need to make a tart base. Their caramelized spiced flavor — cinnamon, nutmeg, a hint of ginger — works very well with red fruits. Crumble them coarsely rather than grinding them to a fine powder: the pieces add crunch to every bite.
- Egg white : Just one white, but it gives the whole mousse its light texture. It must be whipped to stiff peaks, in a perfectly clean and dry bowl — any trace of fat prevents it from rising.
- Sugar + vanilla sugar : Regular sugar adjusts sweetness according to the ripeness of your strawberries. Vanilla sugar adds a subtle roundness that balances the fruit’s acidity without overpowering. If your strawberries are already very sweet, reduce the sugar by a third.
The fruity base
Wash the strawberries, remove the leaves and cut them into pieces. Place them in the blender with the sugar and vanilla sugar, then blend until smooth. The preparation turns a bright pink and immediately gives off that fresh, sweet strawberry scent that promises good things to come. If your strawberries are very ripe, taste before adding all the sugar — you can reduce the amount without problem.
The egg white
In a clean bowl, whip the egg white to stiff peaks with an electric mixer. It takes two to three minutes. The white is ready when it forms peaks that hold without falling and the bowl can be turned upside down without anything moving. This is the only step that needs a bit of attention — an under-whipped white will give a mousse that is too runny and won’t hold in the glass.
Folding
Pour the strawberry purée over the egg white — not the other way around. With a spatula, fold by lifting the mixture from bottom to top, slowly. You see the two textures gradually blend: the broken white of the meringue, the intense red of the purée, until you get a homogeneous mousse of a deep pink. Too-brisk movements break the air bubbles and you end up with a simple coulis rather than a mousse.
Assembly and resting
Crumble the speculoos at the bottom of the glasses — a layer about one centimeter. Pour the mousse on top, then sprinkle a few more crumbs on top. Place in the refrigerator for at least thirty minutes before serving. This chilling step is important: the mousse sets slightly and the flavors concentrate. When it comes out of the fridge, it is firm on the surface but quivering at the center, and the crumbs on top remain crunchy.
Tips & Tricks
- If your strawberries lack fragrance, add a few drops of lemon juice to the purée before blending — it enhances the fruit flavor without adding unpleasant acidity.
- The glasses can be prepared the day before. Stored covered with plastic wrap in the fridge, the speculoos on the bottom will soften slightly and take on a melting texture that some find even better than the initial crunch.
- For a neat presentation, reserve two or three whole strawberries before blending and place half a strawberry on each glass when serving.
Can I use frozen strawberries?
Yes, but they need to be completely thawed and carefully drained before blending — they release a lot of water, which can liquefy the mousse. Fresh seasonal strawberries remain the best choice for flavor and stability.
How do I prevent the mousse from being too runny?
The egg white must be really stiff before folding — if you can turn the bowl upside down without anything falling, it’s good. Folding must be done with slow, wide motions: overmixing breaks the air bubbles and turns the mousse into a coulis.
Can I prepare the glasses the day before?
Absolutely, it’s even recommended for a meal. Cover each glass with plastic wrap and refrigerate until the next day. The speculoos at the bottom will soften slightly, but the mousse will hold well and the flavors will be even more developed.
What can I substitute for speculoos?
Crumbled Breton shortbread works very well and adds a buttery note. Petit-beurre, palets bretons, or even amaretti all give a different character to the mousse. The key is to keep a dry, crunchy biscuit that contrasts with the airy texture of the mousse.
How long do the glasses keep?
The glasses keep for 24 hours in the refrigerator, covered with plastic wrap. After that, the mousse starts to release a little water and loses its hold. It’s best to prepare them the same day or the day before for the next day.
Can I adjust the sugar quantities?
Yes, and it’s even recommended depending on the ripeness of the strawberries. Taste the purée before folding in the egg white and adjust to your liking — very ripe strawberries in season often need 10 to 15 g less sugar. The vanilla sugar, on the other hand, remains for aromatic balance.
Strawberry and speculoos mousse
French
Dessert
A light and fruity mousse that requires no cooking. Strawberry purée blended with sugar, aerated with stiff egg white, sits on a bed of crumbled speculoos whose caramelized crunch contrasts at every bite.
Ingredients
- 250g fresh strawberries, washed and hulled
- 60g granulated sugar
- 1 packet vanilla sugar (7g)
- 1 egg white
- 6 to 8 speculoos
Instructions
- 1Wash, hull and cut the strawberries into pieces. Reserve a few small pieces for decoration if desired.
- 2Place the strawberries in a blender with the sugar and vanilla sugar. Blend until perfectly smooth and fragrant.
- 3In a clean, dry bowl, whip the egg white to stiff peaks with an electric mixer until peaks form that hold without falling.
- 4Pour the strawberry purée over the egg white. Gently fold with a spatula, lifting the mixture from bottom to top, without ever crushing, until you get a homogeneous mousse of a deep pink.
- 5Coarsely crumble the speculoos at the bottom of 6 individual glasses to form a layer about 1 cm thick.
- 6Distribute the mousse among the glasses. Sprinkle with a few speculoos crumbs, decorate with a piece of strawberry if desired, then refrigerate for at least 30 minutes before serving.
Notes
• The quality of the strawberries is crucial: the riper and more fragrant they are, the more flavorful the mousse. Out of season, thawed and well-drained frozen strawberries can work in a pinch.
• For an even lighter texture, fold the egg white in two batches: one third mixed more freely to loosen the purée, then the remaining two thirds delicately.
• The glasses keep for up to 24 hours in the refrigerator covered with plastic wrap. Preparing them the day before intensifies the flavors.
