Ingredients You’ll Need

The beauty of these Raspberry Pistachio Mousse Cakes lies in the quality of the ingredients you choose, with each one playing a key role in delivering unforgettable layers of flavor, texture, and color. While the list is simple, every item is truly essential — from the earthy pistachios to the bright raspberries and luxurious cream.

Shelled Unsalted Pistachios (1/2 cup): The star of both the sponge and mousse, these deliver color and that unmistakable rich, nutty flavor.
Granulated Sugar (1/2 cup plus 2 tablespoons): Adds just the right amount of sweetness to balance tart berries and creamy elements.
Large Eggs (3): Provide structure and richness to the sponge cake, making it light yet satisfying.
All-Purpose Flour (1/4 cup): Gives the sponge its delicate crumb without overpowering the pistachios.
Unsalted Butter (2 tablespoons, melted): Adds a touch of moisture and richness to the cake layer.
Fresh or Frozen Raspberries (1 cup): Bursting with fresh berry flavor and stunning color for the raspberry mousse.
Sugar for Mousse (2 tablespoons): Just enough to highlight the raspberries’ natural tartness.
Lemon Juice (1 teaspoon): Enhances and brightens the raspberry component.
Gelatin (2 teaspoons total): Sets both mousses for a perfect sliceable-but-melt-in-your-mouth texture.
Cold Water (4 tablespoons): Used to bloom the gelatin for optimal texture in your mousse layers.
Heavy Cream (1 cup, divided and whipped): Essential for the airy, creamy texture in both mousse layers.
Milk (1/2 cup): Helps create a silky pistachio mousse base.
Pistachio Paste (1/4 cup): Intensifies the pistachio flavor and tints the mousse a beautiful green.

How to Make Raspberry Pistachio Mousse Cakes

Step 1: Prepare the Pistachio Sponge

Start by preheating your oven to 350°F (175°C) and lining a jelly roll pan with parchment paper to prevent sticking. Pulse the pistachios with sugar in a food processor until you have a fine, fragrant meal — this base creates a tender, nutty sponge. Whisk the eggs in a mixing bowl until they’re pale and thick, then gently fold in your pistachio mixture, flour, and melted butter. Take care not to overmix; the airiness is what gives the sponge its light texture. Spread the batter evenly into the prepared pan and bake for about 10–12 minutes, just until set and lightly golden. Let it cool completely, then cut out rounds with a cookie cutter to fit your desired molds.

Step 2: Make the Raspberry Mousse

In a small saucepan, combine the raspberries, sugar, and lemon juice, cooking until bubbly and juicy. Puree the mixture, then strain it to remove the seeds for an ultra-smooth mousse. While the puree is still warm, bloom your first teaspoon of gelatin in two tablespoons of cold water for five minutes, then gently heat to dissolve. Stir the gelatin mixture into your raspberry puree and allow it to cool slightly so it doesn’t melt the whipped cream. When the mixture is just warm, fold in the freshly whipped cream, being gentle to keep things airy. The result is a delicately pink, berry-bright mousse with a cloud-like finish.

Step 3: Prepare the Pistachio Mousse

Using a clean bowl, bloom the second teaspoon of gelatin in two tablespoons of cold water. In a small saucepan, combine milk and sugar, heating just until warm (not boiling), then whisk in your pistachio paste and the dissolved gelatin until smooth and well-blended. Let this mixture cool to room temperature — patience pays off here, as adding whipped cream to a hot base will deflate your mousse. Once cooled, fold in your whipped cream for a mousse that’s velvety, pale green, and full of pistachio flavor.

Step 4: Assemble the Cakes

Now comes the fun part! Place your rounds of pistachio sponge at the bottom of your silicone or metal ring molds. Spoon or pipe a layer of pistachio mousse directly onto the cake base, smoothing the top. Carefully layer the raspberry mousse on top, finishing with a gentle sweep of your spatula to even the surface. Freeze the assembled cakes for at least four hours, or overnight if planning ahead — this helps the cakes unmold easily and ensures those crisp, clean layers.

Step 5: Unmold and Decorate

Once set, gently unmold each Raspberry Pistachio Mousse Cake. If desired, let them thaw in the fridge for one to two hours until soft and creamy but still firm enough to hold their shape. Now, channel your inner pastry chef and garnish with fresh raspberries, chopped pistachios, or even a shimmering mirror glaze. Every detail makes these cakes truly stunning when brought to the table.

How to Serve Raspberry Pistachio Mousse Cakes

Garnishes

To finish your Raspberry Pistachio Mousse Cakes with a flourish, top each cake with a few whole fresh raspberries and a generous sprinkle of crushed pistachios. A light dusting of powdered sugar or edible flowers adds a whimsical, bakery-worthy touch. For extra drama, a glossy mirror glaze poured over each cake will make them catch the light at your next celebration.

Side Dishes

These cakes shine beautifully on their own, but they pair wonderfully with a side of lightly whipped cream, a handful of fresh berries, or a scoop of pistachio or vanilla gelato. If you’re serving a larger dessert spread, include some crisp almond biscotti or a fruit salad for a bright, lively contrast.

Creative Ways to Present

Because Raspberry Pistachio Mousse Cakes are so pretty, play with presentation! Serve each one on an elegant dessert plate, or try placing a single cake in a clear glass for a modern look. For parties, nestle the cakes on a platter lined with pistachio leaves or edible flowers, or arrange them in a circle for a stunning centerpiece.

Make Ahead and Storage

Storing Leftovers

If you have Raspberry Pistachio Mousse Cakes left after your event (lucky you!), store them in an airtight container in the refrigerator. They’ll stay fresh and delicious for up to three days, retaining their creamy layers and beautiful look.

Freezing

One of the best things about these cakes is how freezer-friendly they are. You can freeze them fully assembled for up to a week; just wrap each cake in plastic wrap and transfer to a sealed container. This is perfect for making the cakes ahead for parties or spontaneous sweet cravings.

Reheating

No reheating required for these glorious, chilled treats! Simply allow frozen mousse cakes to thaw in the refrigerator for one to two hours before serving. This gentle process preserves the smooth, light texture that makes Raspberry Pistachio Mousse Cakes so irresistible.

FAQs

Can I make Raspberry Pistachio Mousse Cakes without a ring or silicone mold?

Yes, you absolutely can! Try using muffin tins lined with plastic wrap or parchment paper. They’ll help hold the layers in shape and make unmolding easier, so you still get those beautiful, bakery-worthy layers.

What if I can’t find pistachio paste?

No worries — you can make a quick homemade version! Simply blend shelled pistachios with a splash of neutral oil or syrup until smooth. The flavor will be wonderful, and you might even prefer your own blend.

Can I use frozen raspberries for the mousse?

Absolutely! Frozen raspberries work just as well and can even make the mousse a bit more vibrant. Just thaw them first and proceed as directed, straining out the seeds for an extra-smooth result.

Is there a vegetarian substitute for gelatin in this recipe?

You can swap gelatin for agar-agar powder in both mousse layers. Use according to package instructions and remember that agar sets more firmly, so use a bit less for a soft, creamy finish.

How far in advance can I prepare Raspberry Pistachio Mousse Cakes?

These elegant cakes can be made up to three days in advance and kept in the freezer until you’re ready to serve. This makes them the ultimate solution for stress-free entertaining or special occasions.
