3-Ingredient Strawberry Mousse Cups

This three-ingredient strawberry mousse is Everything a summer dessert should be — light, creamy, bright with real berry flavor, and no oven required. It comes together in about fifteen minutes, then the fridge does the rest.

Why You’ll Love This

Only 3 ingredients — fresh strawberries, sugar, and heavy cream. That’s it.
No baking, no eggs, no fuss — just blend, whip, fold, and chill.
Real strawberry flavor — made with fresh berries, so it tastes like actual fruit, not candy.
Looks impressive, takes minimal effort — spoon it into wine glasses and it looks like you spent the afternoon cooking.
Light enough to serve after a big meal — airy texture, not heavy or overly sweet.

About the Ingredients

The strawberries need to be good. That’s non-negotiable. I know frozen strawberries exist and I use them for smoothies without a second thought, but for this — use fresh. Use the ones that smell like strawberries when you walk past them at the farmers market, not the ones that smell like nothing in a plastic clamshell. You’ll taste the difference.
The cream — full-fat, very cold, don’t even look at anything that says “lite.” I usually put the carton in the freezer for ten minutes before I use it, along with the bowl. This is not some precious technique thing; it just works better cold and whips faster, and I am always in a hurry.
Sugar is flexible here. My strawberries last weekend were extraordinary — sweet already — so I used maybe two tablespoons less than what this recipe says. Other times the berries need the full amount. Taste as you go.

Ingredients

About 2 cups fresh strawberries, hulled and roughly chopped — plus a few extras if you want something pretty on top
Around 1/3 cup granulated sugar (I probably use a little less most of the time, honestly)
1 cup heavy whipping cream, cold — very cold

Let’s Make It

Start by putting your mixing bowl and the beaters in the freezer. Don’t forget they’re in there. I have forgotten they’re in there. Nothing bad happens, but they get very cold and then your mousse ends up everywhere — anyway, set a timer if you’re forgetful.
While that’s chilling, put the strawberries and sugar in the blender. Let them sit together for five minutes or so. This isn’t strictly necessary but it draws out some juice and the blender doesn’t have to work as hard. Blend until smooth. Taste it. Does it taste like strawberries? Good. Does it taste like nothing? Add a tiny squeeze of lemon juice — I know that’s technically a fourth ingredient but it’s barely a teaspoon and it wakes the whole thing up. I almost always do this.
If you’re fussy about seeds, press the purée through a sieve. I do this maybe half the time. The other half I just leave it and nobody has ever complained.
Now the cream. Take your cold bowl out of the freezer — remembering, this time, that it’s in there — and pour in the cream. Whip it on medium-high until it holds soft peaks. Not stiff, not whipped Butter. Soft and billowy, like it could float away if you let it.
Here’s the part people get nervous about: folding. It’s not complicated. Add a big spoonful of the whipped cream to the strawberry purée and stir it in — this is just to loosen things up, don’t be precious about it. Then add the rest of the cream in two batches, folding slowly with a spatula. Big sweeping motions, gentle. Stop when you don’t see red or white streaks anymore. Don’t keep going. The mousse should look pale pink and cloud-like.
Spoon it into glasses or ramekins or whatever you have. I’ve used wine glasses, regular drinking glasses, those little canning jars. All fine. Refrigerate for at least an hour or two, or longer if you’ve got the time.

Variations

Adding a splash of vanilla to the cream before whipping makes it taste “more desserty” — and honestly, that’s not wrong, though I lean toward leaving it out so the strawberry stays front and center.
I’ve also layered this with crushed shortbread at the bottom of the glass, like a rough parfait, which is very good. You could use graham crackers. You could probably use anything crunchy that you have around. I once used some slightly stale biscotti and it worked fine, which I mention only to say that you don’t need to make a special trip.
If you want it firmer — like you’re putting it in a tart shell or layering it in a trifle — you can bloom a teaspoon of unflavored gelatin in a tablespoon of cold water, melt it gently, and whisk it into the purée before folding in the cream. I’ve done this twice. It works. Holds its shape nicely.

Storing It

This is best the day you make it, or the next day. After that it starts to look a little weepy around the edges — the cream and the fruit slowly want to separate, which is just what they do. You can still eat it. It just won’t be as pretty.
Cover it with plastic wrap or, if you’re out of plastic wrap, a dish towel apparently.

I keep thinking I should serve this more often to guests, and then I make something more elaborate and forget about it until the strawberries come back around. It’s funny which recipes stay in rotation and which ones you have to rediscover every summer like a pleasant surprise. This one keeps surprising me. The color alone — that pale, dusty, unbelievable pink — looks like something that took skill. It didn’t. But I’m not going to be the one to tell people that.
