Ingredients (US + Metric)

Pistachio Mousse

• 1 cup (240 ml) heavy cream, chilled
• 1/2 cup (120 ml) heavy cream, warmed
• 1/3 cup (70 g) pistachio paste or cream
• 3 tbsp (36 g) granulated sugar
• 1/2 tsp (3 ml) vanilla extract
• Pinch of salt

Chocolate Ganache

• 1/2 cup (120 ml) heavy cream
• 4 oz (113 g) semi-sweet chocolate, chopped
• 1 tbsp (14 g) butter

Toppings (Optional)

• Chopped roasted pistachios
• Shaved chocolate
• Whipped cream

Step-by-Step Instructions

1. Make the ganache base

Warm the heavy cream in a small saucepan until it just starts to steam. Don’t let it boil—you only want gentle heat.

2. Add chocolate

Pour the hot cream over the chopped chocolate in a heat-safe bowl. Let it sit for a minute so the chocolate softens, then stir until completely smooth. Add the butter and mix until glossy.

Set aside to cool slightly—it should thicken but still be pourable.

3. Layer the ganache

Spoon a thin layer of chocolate ganache into the bottom of your serving glasses. Chill for 10–15 minutes so it firms up a bit before the mousse goes on top.

4. Make the mousse

In a mixing bowl, whip the chilled heavy cream with sugar and salt until soft peaks form. Don’t go too far—you don’t want it grainy.

5. Warm the pistachio base

In a separate bowl, mix the warmed cream with pistachio paste and vanilla until smooth. This loosens the pistachio paste and keeps the mousse silky.

6. Combine gently

Add a scoop of whipped cream to the pistachio mixture to lighten it, then fold in the rest using a spatula. Take your time—you want to keep the airiness.

7. Assemble

Spoon or pipe the pistachio mousse over the chilled ganache layer. Smooth the tops or swirl them for a rustic look.

8. Chill

Refrigerate for at least 1 hour. The mousse firms up beautifully and the flavors meld together.

Serving Ideas

You can serve this dessert beautifully with:

• Extra chopped pistachios for crunch
• A drizzle of leftover ganache
• Fresh berries for brightness
• A small dollop of whipped cream
• Crushed amaretti or biscotti on top

Variations & Customizations

Here are some fun ways to make it your own:

• Use white chocolate instead of dark for a sweeter ganache.
• Add a touch of orange zest for a citrus lift.
• Fold in mini chocolate chips for texture.
• Layer crushed pistachio cookies between mousse and ganache.
• Swap pistachio for almond or hazelnut paste.

Storage & Make-Ahead Tips

• Store covered in the fridge for up to 3 days.
• You can make the mousse a day ahead—just assemble and chill.
• Ganache can be prepared up to 48 hours in advance and gently rewarmed.
• Avoid freezing—the texture changes and becomes grainy.

Pro Tips & Mistakes to Avoid

These little tricks keep everything smooth and dreamy:

• Make sure your mixing bowl and whisk are cold—it helps cream whip faster.
• Don’t overwhip the cream; stop at soft to medium peaks for the airiest mousse.
• Warm the pistachio paste mixture so it blends without lumps.
• Let the ganache cool slightly so it doesn’t melt into the mousse layer.
• Always fold gently; stirring too hard knocks out all that lovely air.
