This velvety coffee mousse kicks your caffeine love up a notch while hitting your sweet spot. Dark chocolate meets espresso in this mouthwatering treat that's surprisingly easy to throw together with just 5 ingredients and hardly any prep work.
I came up with this mousse when I needed a fast but fancy dessert for guests coming over. Everyone went crazy for the coffee-chocolate combo, and now it's what I make whenever I want something special without spending all day in the kitchen.
Ingredients
- Heavy cream: This forms your mousse base and gives that fluffy, lightweight feel when it's beaten until it stands up
- Milk: Makes everything smoother while cutting through the heaviness of the cream
- Espresso or strong coffee: Your main flavor player – make sure to use cooled, freshly brewed coffee for the best taste
- Confectioners sugar: Adds sweetness without any gritty texture and helps your whipped cream stay firm
- Dark chocolate: Brings depth and richness – grab a good quality bar with 70% cocoa or more for the best outcome
Step-by-Step Instructions
- Whip the Cream:
- Grab your stand mixer or hand mixer and beat the heavy cream on medium-high until it forms stiff peaks in about 3-4 minutes. You'll know it's ready when you lift the beater and the cream stands straight up without flopping over. Don't beat too long or you'll end up with butter instead.
- Prepare the Coffee-Chocolate Base:
- In another big bowl, mix together your cooled milk, coffee or espresso, confectioners sugar, and melted chocolate. Keep stirring until everything's smooth and blended well. Make sure your chocolate isn't too hot to melt the cream but still runny enough to mix in easily.
- Fold in the Whipped Cream:
- With a rubber spatula, slowly fold about a third of your whipped cream into the coffee-chocolate mix to lighten it up. Then carefully add the rest of the cream using gentle up-and-over movements until you can't see any white streaks. Don't stir too hard or your mousse will flatten out.
- Chill and Set:
- Pour the mixture evenly into six serving cups or dishes. If you want it to look fancy, use clear glasses to show off the beautiful brown coffee color. Stick them in the fridge for at least two hours, but leaving them overnight works even better so the flavors can really sink in and the mousse can set up nicely.

Dark chocolate really works magic in this dessert. I tried it with milk and semisweet kinds too, but dark chocolate just clicks perfectly with the coffee flavor and adds that grown-up bitterness that keeps the whole thing from getting too sweet.
Make It Your Own
This coffee mousse works great as a starting point you can tweak however you want. Pour in a spoonful of Kahlúa or Baileys for a boozy grown-up version. A bit of vanilla or a tiny sprinkle of cinnamon can really bring out the flavors without drowning out that coffee taste you're after.

Serving Suggestions
Take this simple dessert up a notch with some quick finishing touches. Sprinkle a bit of cocoa powder, add some chocolate curls, or drop a few coffee beans on top for that wow factor with barely any work. For some crunch, toss on some crushed chocolate-covered espresso beans or serve with a cookie on the side. The mousse is plenty rich on its own but tastes amazing with some berries to cut through the richness.
Perfect Make-Ahead Dessert
The best thing about this coffee mousse is it actually tastes better the longer it sits. Making it a day early lets all the flavors mix and mingle, giving you a deeper taste experience. That's why it's so great for parties when you want to get dessert out of the way and focus on other cooking the day your guests arrive.
