Strawberry mousse is one of those quietly elegant desserts that looks like you fussed for hours but actually comes together in minutes. Classic French mousse is typically a bit more involved—often using eggs, sometimes gelatin, and a careful folding technique to achieve that airy texture. Here, we’re borrowing the spirit of that tradition but streamlining it into a three-ingredient version that’s weeknight-friendly and very forgiving. You get the same cloud-like texture and bright berry flavor without a long ingredient list or special equipment. This is the kind of recipe you pull out when strawberries are sweet and plentiful, or when you want a light, refreshing finish to a rich meal without turning on the oven.
These strawberry mousse cups are lovely on their own, but they play nicely with a few simple sides. I like to serve them with crisp butter cookies or shortbread fingers for a bit of contrast and crunch. A small plate of fresh berries—raspberries, blueberries, or sliced peaches—turns this into a more substantial dessert platter, especially if you’re entertaining. For something richer, pair the mousse with a thin slice of flourless chocolate cake or a dark chocolate tart; the bitterness of the chocolate balances the sweetness of the mousse beautifully. If you’re serving a multi-course meal, this mousse also works well after something savory and herb-forward, like grilled chicken with a green salad, because its clean, fruity flavor resets the palate without feeling heavy.
3-Ingredient Strawberry Mousse CupsServings: 4
Ingredients
2 cups fresh strawberries, hulled and roughly chopped (plus a few extra for garnish, optional)
1/3 cup granulated sugar (adjust to taste based on berry sweetness)
1 cup heavy whipping cream, well chilled
Directions
Prepare the strawberries: Place the chopped strawberries and granulated sugar in a blender or food processor. Let them sit for about 5 minutes so the sugar starts to draw out some of the juices, which helps the mixture blend more smoothly.
Blend the purée: Blend the strawberries and sugar until completely smooth. Taste and adjust sweetness if needed, keeping in mind that the richness of the cream will soften the perceived sweetness later. If you prefer a very silky mousse, press the purée through a fine-mesh sieve to remove seeds. Set aside.
Chill the mixing bowl: Place a medium mixing bowl and the beaters or whisk attachment in the refrigerator or freezer for 10–15 minutes. Cold equipment helps the cream whip faster and hold its structure better.
Whip the cream: Pour the chilled heavy cream into the cold bowl. Using a hand mixer or stand mixer, whip on medium-high speed until medium-stiff peaks form. The cream should hold its shape but still look soft and billowy, not grainy.
Lighten the strawberry mixture: Transfer the strawberry purée to a large bowl. Add about one-third of the whipped cream and gently fold it in with a spatula. This first addition loosens the purée so the remaining cream can be folded in without deflating too much.
Fold in the remaining cream: Add the rest of the whipped cream in two additions, folding gently each time. Use broad, sweeping motions, lifting from the bottom of the bowl and turning as you go, just until no streaks of white or bright red remain. Avoid overmixing, which can knock out the air you’ve just incorporated.
Portion the mousse: Spoon or pipe the mousse into 4 small glasses, ramekins, or dessert cups. If you’d like neater layers, transfer the mousse to a piping bag or a zip-top bag with a corner snipped off and pipe it in.
Chill and serve: Cover and refrigerate the mousse cups for at least 1–2 hours, or until set and well chilled. Just before serving, garnish with sliced strawberries or a small whole berry on top, if desired. Serve cold.
Storage: The mousse is best enjoyed within 24 hours, though it will keep, covered and refrigerated, for up to 2 days. Over time, a bit of separation may occur; if so, simply enjoy it as is rather than trying to stir it back together.
Variations & Tips
To adjust sweetness and flavor, treat the sugar as flexible: if your strawberries are peak-season and very sweet, you may only need a few tablespoons; for less-ripe berries, you might prefer the full 1/3 cup or a touch more. A squeeze of lemon juice (technically a fourth ingredient, but just a teaspoon or two) will sharpen the berry flavor and keep the mousse from tasting flat. For a slightly more complex profile without changing the base recipe, add 1/2 teaspoon of vanilla extract to the whipped cream before beating, or a splash of balsamic vinegar to the strawberry purée for a subtle, grown-up depth. You can also layer the mousse with crushed cookies—like graham crackers, shortbread, or vanilla wafers—for a parfait-style dessert. If you’d like a firmer, more sliceable mousse for a trifle or tart filling, dissolve 1 teaspoon of unflavored gelatin in 1 tablespoon of cold water, melt it gently, and whisk it into the strawberry purée before folding in the cream. Finally, this method adapts well to other fruits: try raspberries or a mix of berries, keeping in mind that more tart fruits may need a bit of extra sugar to balance the flavor.
