Why You’ll Love this 5-Ingredient Blender Chocolate Mousse
Simplicity meets elegance in this ridiculously easy chocolate mousse. I’m talking five ingredients, one blender, and zero complicated techniques. Who’s time for tempering eggs or whipping cream separately when you can toss everything together and press a button?
The texture is what’ll win you over—silky smooth, perfectly aerated, with that deep chocolate intensity that makes your eyes close involuntarily. And the prep time? Just minutes, really. The hardest part is waiting those two hours while it chills.
Perfect for last-minute dinner parties or those nights when your sweet tooth demands something more sophisticated than ice cream.
What Ingredients are in 5-Ingredient Blender Chocolate Mousse?
This chocolate mousse requires just five simple, everyday ingredients that combine to create something truly magical.
- 7 ounces semi-sweet chocolate, finely chopped
- ¼ cup boiling water
- ½ cup heavy cream
- ½ teaspoon vanilla extract
- 1 egg (pasteurized preferred)
Quality matters when working with so few ingredients, so I recommend using the best chocolate you can find—it’s the star of the show, after all, and will determine the depth and richness of your final dessert.
How to Make this 5-Ingredient Blender Chocolate Mousse
Step 1: Finely Chop the Chocolate
Take 7 ounces of semi-sweet chocolate and chop it as finely as possible.
This isn’t just about being fancy—finely chopped chocolate melts more evenly, which means smoother mousse without those pesky little unmelted bits.
Step 2: Add Chocolate to Blender
Place all your finely chopped chocolate into the blender.
Make sure it’s distributed evenly at the bottom so the hot water can reach all the pieces.
Step 3: Pour in Boiling Water
Add ¼ cup of boiling water directly over the chocolate in the blender.
The heat will start melting the chocolate immediately, which is exactly what we want.
Step 4: Blend Until Smooth
Blend for about 30 seconds, then pause to scrape down the sides.
This helps catch any chocolate that’s trying to escape the melting process.
Continue blending for another 15 seconds.
For the most consistent and professional results, a premium stand mixer with a blender attachment will ensure perfect texture every time.
Step 5: Add Remaining Ingredients
Add ½ cup heavy cream, ½ teaspoon vanilla extract, and 1 egg (preferably pasteurized for safety).
These ingredients transform our chocolate mixture from merely melted chocolate into a proper mousse.
Step 6: Final Blending
Blend everything for about 15 seconds, pause to scrape down the sides again, then continue blending until the mixture becomes completely smooth.
You’re looking for a glossy, uniform consistency without any streaks.
Step 7: Pour and Refrigerate
Pour the mousse mixture into individual serving glasses.
Something clear works wonderfully here—who doesn’t want to see this beautiful dessert while anticipating that first spoonful?
Step 8: Chill Thoroughly
Cover each glass with cling wrap (right on the surface to prevent a skin from forming) and refrigerate for at least 2 hours.
The waiting is the hardest part, but it’s during this time that the mousse sets to its perfect texture.
What to Serve with 5-Ingredient Blender Chocolate Mousse
This silky chocolate mousse is a dessert that deserves proper accompaniments! For a simple but elegant finish, try fresh raspberries or sliced strawberries—the slight tartness cuts through the richness perfectly.
A dollop of lightly sweetened whipped cream on top creates a beautiful contrast in both flavor and texture. Coffee lovers might appreciate an espresso on the side, as the bitter notes complement chocolate beautifully.
For a more substantial dessert spread, pair with crisp butter cookies or delicate almond tuiles for dipping. And don’t underestimate the power of a light sprinkle of flaky sea salt on top—it’ll make those chocolate flavors absolutely sing.
This mousse works beautifully as an after-dinner treat or for special afternoon gatherings.
5-Ingredient Blender Chocolate Mousse Substitutions and Variations
- Fun Garnishes: Try chocolate shavings, crushed peppermint during holidays, a sprinkle of espresso powder, or edible gold leaf for special occasions.
- Lower Sugar: Use stevia-sweetened chocolate chips and add a touch of pure stevia to maintain sweetness while reducing sugar.
Leftovers and Storage for this 5-Ingredient Blender Chocolate Mousse
This silky chocolate mousse keeps beautifully in the refrigerator for up to 3 days when stored in airtight containers or covered with cling wrap pressed directly onto the surface.
The flavors actually develop and deepen overnight, making this dessert perfect for preparing a day ahead.
For longer storage, you can freeze individual portions for up to 1 month.
Simply thaw overnight in the refrigerator before serving. No reheating needed—this is a cold dessert through and through!
If you notice any condensation forming after refrigeration, gently blot with a paper towel before serving.
To revive day-old mousse that’s lost some of its luster, a fresh garnish of chocolate shavings or a light dusting of cocoa powder works wonders to make it look (and taste) freshly made.
Final Thoughts
This blender chocolate mousse captures what dessert should be—simple to make yet impossibly luxurious.
With just five ingredients and minimal hands-on time, it transforms ordinary chocolate into something that feels special enough for company but easy enough for a weeknight craving.
I love how it’s perfect for those times when you want to impress without spending hours in the kitchen—whether you’re hosting an impromptu dinner party or need a make-ahead dessert for a busy holiday gathering.
The beauty of this mousse lies not just in its silky texture, but in how it reminds us that sometimes, the most satisfying desserts come from the simplest techniques and the purest ingredients.
