Velvety pistachio mousse layered over rich chocolate ganache was born out of a weekend craving for something elegant yet easy. This simple glass dessert impresses every time and delivers the perfect balance of creamy nutty lightness and bittersweet chocolate. If you need a make-ahead dessert for guests or a way to indulge your pistachio obsession this is a go-to.

I tasted my first spoonful of pistachio mousse in a tucked-away Milan café and never forgot the creamy texture. Now it is my secret move for friend gatherings and everyone asks for the recipe.

Ingredients

  • Dark chocolate: Just choose bars with sixty to seventy percent cocoa for deep flavor and smooth melting
  • Heavy cream: Guarantees both the ganache and mousse have a luxurious mouthfeel
  • Unsalted pistachios: For the mousse pick ones that are vivid green for the best color and freshest taste
  • Mascarpone or cream cheese: Makes the mousse stable and incredibly rich look for smooth fresh cheese at the store
  • Vanilla extract: Brings out both the pistachio and chocolate notes search for real extract or even paste if possible
  • Quality butter (optional): In ganache will add shine so use a good creamy block if you can
  • Chopped pistachios or chocolate shavings: As garnish give crunch and visual flair

Instructions

Prepare the Chocolate Ganache:
Warm the heavy cream on the stove until steam rises just before it boils whisking so it does not catch. Pour the hot cream straight over chopped chocolate in a heatproof bowl making sure every bit is covered. Let the mixture sit undisturbed for one minute then gently stir with a spatula until everything is silky and glossy. If desired stir in butter until melted. Divide ganache into six small glasses filling a quarter full then refrigerate to chill.
Make the Pistachio Paste:
For a vibrant mousse blanch pistachios if desired then place shelled nuts with sugar salt and vanilla in a food processor. Blend to a paste adding a splash of cream if needed. The paste should be thick yet spreadable.
Whip the Mousse:
Beat cold heavy cream to soft peaks. In another bowl beat mascarpone smooth then mix in pistachio paste until blended with no streaks. Fold in the whipped cream gently in two additions for airy mousse.
Assemble the Layers:
Once ganache is firm gently spoon or pipe mousse on top filling glasses to the rim. Smooth the surface cover and chill at least two hours for set layers.
Garnish and Serve:
Before serving top each glass with chopped roasted pistachios and chocolate shavings. For extra luxury add gold or sea salt flakes. Serve chilled for best texture.

There is something so satisfying about the savory pop of salted roasted pistachios on top. My niece once tried to sneak every last garnish from her cousins' glasses which still cracks me up every time we make these together.

Storage and Leftover Tips

If you have extras cover each glass tightly with plastic wrap or a snap-on lid before keeping in the fridge. The mousse stays creamy and the ganache will not seize or dry out. Pistachio mousse holds up well for lunchbox treats too just avoid the garnishes until the moment you serve.

Easy Ingredient Swaps

No mascarpone on hand swap in full fat cream cheese or even a thick Greek yogurt for a tangy twist. If you only have milk chocolate try reducing the sugar in the pistachio paste so it stays balanced. Almonds can substitute for pistachios in a pinch but the color will be less vivid and the flavor milder.

Perfect Ways to Serve This

Serve each glass with a crisp almond cookie for dunking or pair with fresh berries for added brightness. A drizzle of espresso over the mousse transforms it into a wonderful adult dessert with extra depth.

The Story Behind This Recipe

This dessert came together thanks to a box of Sicilian pistachios I could not resist at the market. Mixing them with bittersweet chocolate was inspired by an Italian cookbook I loved as a teenager. Sharing these layered treats with family has turned into a little tradition for birthday nights and special dinners.

Recipe Q&A

→ How can I achieve a vibrant green mousse?

Blanch pistachios by boiling for 1 minute, then peeling before blending. This enhances color naturally.

→ Can I use cream cheese instead of mascarpone?

Yes, cream cheese works well. It offers a slightly tangier flavor but maintains the mousse’s creamy texture.

→ How do I prevent the ganache from hardening too much?

Use a higher cream-to-chocolate ratio and avoid over-chilling before assembling the dessert.

→ Can the dessert be made ahead?

Absolutely. Prepare and refrigerate for up to 24 hours. Add toppings just before serving for freshness.

→ What garnishes pair best for added flair?

Top with roasted pistachios, chocolate curls, sea salt flakes, or edible gold dust for impressive presentation.

Difficulty: Moderate

Regional Style: Modern European

Output: 6 Portions (6 small individual mousses)

Dietary Attributes: Vegetarian, Gluten-Free

Needed Ingredients

→ Chocolate Ganache

01 7 oz dark chocolate (60–70% cocoa), chopped
02 3/4 cup plus 1 tablespoon heavy cream
03 1 tablespoon unsalted butter (optional, for extra shine)

→ Pistachio Mousse

04 1 1/4 cups shelled unsalted pistachios
05 3 tablespoons granulated sugar
06 1 teaspoon pure vanilla extract
07 1 cup heavy cream, cold
08 1/2 cup mascarpone cheese or cream cheese, softened
09 Pinch of salt

→ Optional Garnishes

10 Chopped roasted pistachios
11 Chocolate curls or shavings
12 Edible gold dust or sea salt flakes

Preparation Steps

Step 01

Heat heavy cream over medium heat just to a simmer without boiling. Pour over chopped dark chocolate in a heatproof bowl and let stand for 1 minute. Stir gently until an even, glossy mixture forms. For added shine, incorporate unsalted butter at this stage, if desired.

Step 02

Spoon the warm ganache into 6 small serving glasses, filling each about one-quarter full. Refrigerate the glasses to chill the ganache while preparing the mousse.

Step 03

Optional for enhanced color: Blanch pistachios by simmering for 1 minute, transferring to an ice bath, and peeling skins. Blend peeled pistachios, granulated sugar, salt, and vanilla extract in a food processor until finely ground, adding a splash of cream if necessary to reach a smooth paste.

Step 04

Using an electric mixer, whip cold heavy cream until soft peaks form. In a separate bowl, beat softened mascarpone or cream cheese until completely smooth. Combine the pistachio paste with the mascarpone until evenly incorporated.

Step 05

Gently fold the whipped cream into the pistachio-mascarpone mixture in two additions, maintaining as much volume as possible for a light texture.

Step 06

When the ganache layer is firm, carefully spoon or pipe pistachio mousse over the ganache, filling the glasses fully. Level the tops, cover loosely, and refrigerate for at least 2 hours to set.

Step 07

Just before serving, garnish each portion with chopped roasted pistachios, chocolate curls, and, if desired, a sprinkle of gold dust or sea salt flakes. Serve chilled.
