How to Make Chocolate Mousse Cupcakes Recipe
Step 1: Prepare the Triple Chocolate Cupcakes
Start by following the directions on the box for the triple chocolate cake mix, adding the eggs, softened butter, and whole milk as required. This forms your rich, moist chocolate cupcake base. Pour the batter into cupcake liners, filling each about two-thirds full to allow room for rising, then bake for 18-21 minutes. Once baked, transfer to a cooling rack and let them come to room temperature.
Step 2: Whip Up the Silky Chocolate Mousse
In a bowl, gently heat the semi-sweet chocolate chips with a splash of whole milk until just melted and glossy, then stir until perfectly smooth. In a separate bowl, whip the heavy cream with powdered sugar until soft peaks form. Fold the melted chocolate into the whipped cream carefully to maintain the airy texture. This mousse layer is where the magic begins — luscious, light, and chocolatey.
Step 3: Incorporate the Crushed Oreos
Gently fold the crushed Oreos into the mousse mixture to introduce a delightful crunch. This little surprise adds texture contrast and complements the smooth chocolate beautifully. Be sure not to overmix to keep the mousse fluffy.
Step 4: Assemble the Cupcakes
Once your cupcakes are completely cool, pipe or spoon a generous amount of chocolate mousse over each cupcake, letting it cascade naturally. The mousse layer adds a dreamy, creamy finish atop the moist cake, balancing flavor and texture.
Step 5: Make the Chocolate Frosting
Beat softened unsalted butter until creamy, then gradually add powdered sugar and vanilla extract. Melt the semi-sweet chocolate chips and mix into the butter mixture, adding heavy whipping cream spoonful by spoonful until you reach a smooth, spreadable consistency. This frosting will be rich yet airy, perfect for topping off your cupcakes with elegance.
Step 6: Frost and Decorate
Pipe the chocolate frosting onto each mousse-topped cupcake in beautiful swirls. For an extra pop, sprinkle mini chocolate chips on top. This final step is where your cupcakes take on their irresistible, picture-perfect finish.
How to Serve Chocolate Mousse Cupcakes Recipe

Garnishes
The garnish is your chance to add a personal touch and another layer of texture or flavor. Try delicate chocolate shavings, a dusting of cocoa powder, or crushed Oreos to echo the interior crunch. Fresh raspberries or a hint of mint can also brighten the presentation and add a refreshing contrast to the rich chocolate.
Side Dishes
While these cupcakes shine on their own, pairing them with a light, tart fruit salad or a scoop of vanilla bean ice cream elevates the experience. The fruit’s acidity or the cool creaminess of ice cream cuts through the dense chocolate and mousse, creating a balanced, memorable dessert.
Creative Ways to Present
For a party, arrange these cupcakes in a pyramid tower or serve them in decorative cupcake liners to match your theme. You can also serve them with mini dessert forks or atop a bed of edible flowers for a sophisticated touch. The Chocolate Mousse Cupcakes Recipe adapts beautifully to any vibe you wish to create.
Make Ahead and Storage
Storing Leftovers
Store leftover cupcakes in an airtight container in the refrigerator to keep the mousse and frosting fresh. They will stay moist and delicious for up to 3 days. Make sure to bring them to room temperature before serving for the best texture.
Freezing
You can freeze these cupcakes by wrapping each individually in plastic wrap and placing them in a freezer-safe container. To enjoy later, thaw in the refrigerator overnight. Freezing helps maintain the integrity of the mousse and cake without compromising flavor.
Reheating
Since these are best served chilled or at room temperature, reheating is not recommended. Instead, allow frozen cupcakes to defrost naturally and enjoy the mousse’s creamy texture unaltered.
FAQs
Can I use dark chocolate instead of semi-sweet chocolate chips?
Absolutely! Dark chocolate works beautifully in this recipe and offers a slightly more intense chocolate flavor that complements the mousse and frosting well. Just be mindful of the sweetness balance.
How long does it take to make the Chocolate Mousse Cupcakes Recipe?
From start to finish, including prep and baking, expect about one hour. Much of that time is hands-off baking or chilling, allowing you to prep other things in the meantime.
Can I make these cupcakes vegan or dairy-free?
While this exact recipe is not vegan due to eggs, butter, and cream, you can experiment with vegan substitutes like coconut cream, dairy-free butter, and egg replacers to adapt the recipe. The texture might vary slightly but the chocolate flavor will still be amazing.
What’s the best way to pipe the mousse and frosting?
Use a piping bag fitted with a large round tip for the mousse for a smooth dollop, and a star tip for the frosting to create pretty swirls. If you don’t have piping bags, a spoon works just as well for a generous and rustic look.
Can these cupcakes be made ahead for a party?
Yes! You can bake the cupcakes a day or two ahead, prepare the mousse and frosting, and assemble on the day of the event for the freshest taste. The make-ahead instructions above support easy planning for special occasions.

Ingredients
Cake:
- 1 box triple chocolate cake mix
- 3 large eggs
- 1/2 cup softened unsalted butter
- 1 cup whole milk
Mousse Filling:
- 3 large egg yolks
- 6 tablespoon powdered sugar
- 1 ⅔ cup heavy whipping cream
- 1 cup semi sweet chocolate chips
- 5 crushed Oreos
- 3 tablespoons whole milk
Frosting:
- 1 cup heavy whipping cream
- 2 cup semi sweet chocolate chips
- 2 cup unsalted butter (softened)
- 4 ½ cup powdered sugar
- 2 teaspoons pure vanilla extract
- 3 – 6 tablespoons heavy whipping cream (to adjust consistency)
Decoration:
- 1 cup mini chocolate chips
Instructions
- Prepare the Cake Batter: Preheat your oven as directed on the cake mix box. In a large bowl, combine the triple chocolate cake mix with 3 large eggs, 1/2 cup softened unsalted butter, and 1 cup whole milk. Mix until smooth and well combined.
- Bake the Cupcakes: Line cupcake pans with paper liners and divide the batter evenly among them. Bake for approximately 21 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and let them cool completely on a wire rack.
- Make the Chocolate Mousse Filling: In a double boiler or microwave, melt 1 cup semi sweet chocolate chips until smooth. In a separate bowl, whisk together 3 large egg yolks, 6 tablespoons powdered sugar, and 3 tablespoons whole milk until thickened. Fold the melted chocolate into this mixture. In another bowl, whip 1 ⅔ cups heavy whipping cream until stiff peaks form. Gently fold the whipped cream into the chocolate mixture. Finally, fold in 5 crushed Oreos to the mousse for added texture and flavor.
- Fill the Cupcakes: Once the cupcakes have cooled, use a small knife or cupcake corer to remove the center of each cupcake. Fill each hollow with the prepared chocolate mousse filling.
- Prepare the Chocolate Buttercream Frosting: Melt 2 cups semi sweet chocolate chips until smooth. In a large mixing bowl, beat 2 cups softened unsalted butter until creamy. Gradually add 4 ½ cups powdered sugar, then the melted chocolate, and 2 teaspoons pure vanilla extract. Beat well until combined. Add 3 to 6 tablespoons heavy whipping cream as needed to reach a spreadable consistency.
- Frost and Decorate: Pipe or spread the chocolate buttercream frosting onto each filled cupcake. Sprinkle 1 cup mini chocolate chips on top for garnish. Refrigerate if not serving immediately to allow the mousse and frosting to set.
Notes
- For the chocolate mousse, ensure the egg yolks are cooked gently when mixing to avoid scrambling—use a double boiler method or low heat.
- Make sure cupcakes are completely cooled before filling to prevent the mousse from melting.
- The frosting consistency can be adjusted with whipping cream to achieve smooth spreading or piping.
- Store cupcakes in the refrigerator and consume within 2-3 days for optimal freshness.
- Allow cupcakes to come to room temperature before serving for the best flavor and texture.
