Save The first time I served this dessert, I was convinced I'd overwhipped the cream and ruined everything. I stood in my kitchen, staring at the bowl, certain the mousse would collapse into a sugary puddle. But when I folded in that vibrant strawberry puree, it billowed into something impossibly light, almost defiant in its airiness. I spooned it into glasses with shaky confidence, layered on the ganache, and crossed my fingers. Two hours later, when I pulled those chilled glasses from the fridge, I realized I'd made something that looked like it belonged in a pastry case, not my chaotic weeknight kitchen.
I made this for my sister's birthday once, and she accused me of ordering it from a bakery. She refused to believe I'd actually whipped cream in my own kitchen until I showed her the berry-stained blender still sitting in the sink. That moment, watching her take the first spoonful and go quiet, taught me that some recipes don't just feed people, they rewrite what they think you're capable of. Now I make it whenever I want to remind someone, including myself, that a little effort can feel like magic.

Ingredients
- Fresh strawberries: The soul of this mousse, their natural sweetness and slight tartness balance the richness of the cream, and pureeing them releases a vivid color that makes the dessert look as good as it tastes.
- Granulated sugar: Just enough to coax out the berry flavor without masking it, and it helps the gelatin dissolve smoothly into the warm puree.
- Powdered gelatin: This is what gives the mousse its structure, transforming whipped cream into something that holds its shape yet melts on your tongue.
- Cold water: Blooming the gelatin here ensures it dissolves evenly and doesn't clump when you stir it into the warm strawberry mixture.
- Heavy cream, chilled: The colder it is, the faster it whips and the more stable your mousse will be, so I always stick mine in the freezer for ten minutes before starting.
- Pure vanilla extract: A whisper of warmth that ties the strawberry and cream together without announcing itself.
- Pinch of salt: It sharpens the sweetness and makes every other flavor more vivid, a trick I learned from a baker who swore by it.
- Semi-sweet or dark chocolate, chopped: The ganache layer needs good chocolate, something with depth that won't taste waxy or flat after it cools.
- Heavy cream for ganache: When heated and poured over chocolate, it creates that glossy, silky texture that makes you want to lick the spoon.

Instructions
- Puree and Strain the Strawberries:
- Blend the hulled berries until they're completely smooth, then press the puree through a fine mesh sieve to catch the seeds. You'll end up with a silky, jewel-toned liquid that's worth the extra step.
- Warm the Strawberry Mixture:
- Combine the puree and sugar in a small saucepan over medium heat, stirring until the sugar dissolves and the mixture just starts to simmer. Pull it off the heat as soon as you see gentle bubbles, you're not cooking jam here.
- Bloom and Dissolve the Gelatin:
- Sprinkle the gelatin over cold water in a small bowl and let it sit for five minutes until it looks swollen and spongy. Stir it into the warm strawberry mixture until it disappears completely, then let everything cool to room temperature so it doesn't deflate your whipped cream later.
- Whip the Cream:
- In a large bowl, beat the chilled heavy cream with vanilla and a pinch of salt until it forms soft, billowy peaks that hold their shape but still look creamy. Stop before it gets stiff or grainy, you want it to fold smoothly with the strawberry base.
- Fold and Chill the Mousse:
- Gently fold the cooled strawberry mixture into the whipped cream using a spatula, cutting down through the center and sweeping up the sides until everything is pale pink and uniform. Spoon or pipe it into serving glasses, filling each about two-thirds full, then refrigerate for at least an hour until the mousse is set and no longer jiggly.
- Make the Chocolate Ganache:
- Put the chopped chocolate in a heatproof bowl, heat the cream in a small saucepan until it's just starting to simmer, then pour it over the chocolate and let it sit undisturbed for two minutes. Stir slowly until the ganache is smooth and glossy, then let it cool to room temperature so it doesn't melt the mousse layer beneath it.
- Layer and Set:
- Spoon or pour the cooled ganache over the set strawberry mousse in each glass, creating a distinct chocolate layer on top. Return the glasses to the fridge for at least another hour, or until the ganache is firm and no longer sticky to the touch.
- Garnish and Serve:
- Right before serving, top each glass with a fresh strawberry half, a few curls of shaved chocolate, or a sprig of mint. The contrast between the cold mousse and the deep chocolate makes every spoonful feel like a small event.
Save There was a dinner party where I served these in mismatched vintage glasses I'd found at a thrift store, and someone said they looked like something out of a French patisserie window. I didn't tell them I'd been frantically whipping cream in my pajamas two hours earlier, or that I'd almost given up when the gelatin looked lumpy. I just smiled and spooned out seconds, realizing that sometimes the best compliments come from the things we almost didn't believe we could pull off.

Making It Ahead
This dessert actually improves when you make it the day before, giving the mousse time to fully set and the flavors to meld together in the fridge. I've kept these chilled for up to 24 hours without any loss of texture, and they come out even more composed and elegant. Just wait to add the garnish until right before serving so the strawberries stay bright and the chocolate curls don't get soggy. It's the kind of make-ahead magic that turns a stressful dinner party into something you can actually enjoy.
Choosing Your Chocolate
I learned the hard way that not all chocolate behaves the same in ganache. The first time I made this, I used whatever was in the pantry, and the ganache seized into a grainy mess that I had to scrape off and start over. Now I reach for something in the 60 to 70 percent cacao range, dark enough to balance the sweet mousse but not so bitter it fights with the strawberries. Semi-sweet works beautifully too, especially if you're serving this to people who prefer their chocolate on the mellower side.
Serving Suggestions
These look stunning in clear glasses where you can see the layers, but I've also spooned them into small ramekins or even teacups when I'm feeling whimsical. A splash of Grand Marnier in the strawberry puree adds a grown-up edge that pairs beautifully with the chocolate, though I usually skip it when kids are at the table. If you're feeling fancy, a dollop of lightly sweetened whipped cream on top just before serving makes it feel like a restaurant dessert.
- Pair it with sparkling wine or champagne for a celebration that feels effortless.
- Serve it after a rich meal, the lightness of the mousse is a relief when everyone's already full.
- Double the recipe if you're feeding a crowd, it scales up beautifully and keeps well in the fridge.
Save Every time I make this, I'm reminded that some of the best things in the kitchen come from trusting the process even when it looks like a mess halfway through. Pull it from the fridge, spoon into that first layer, and let it surprise you all over again.
