2 eggs
⅓ cup (70g) sugar
⅔ cup (70g) roasted pistachios, ground
1 tbsp (10g) all-purpose flour
1 tbsp (15g) butter, melted
2 oz (60g) white chocolate
1 tbsp (15g) whipping cream
½ cup (50g) roasted pistachios, chopped (for added crunch!)
10 oz (300g) fresh or frozen raspberries (some for decoration, too!)
¼ cup (50g) sugar (for the mousse, because we like it sweet)
1 tbsp (15ml) lemon juice (to brighten the flavors)
½ tbsp (5g) gelatin powder (for that light and airy mousse)
2 tbsp (30g) cold water (to activate the gelatin)

Feel free to sub out the raspberries for any berries you have on hand. Blueberries or strawberries would work beautifully, too!

How to Make Pistachio Cake with Raspberry Mousse

Prepping the Cake

Alright, let’s get that oven preheated to 350°F (175°C) while we prep our cake. Grease up your favorite cake pan with a little butter or non-stick spray.

Whisk the Eggs & Sugar: In a medium bowl, beat the eggs with the sugar until everything is light and fluffy, about 3-5 minutes. You want it to have that airy texture!
Fold in the Good Stuff: Gently fold in the ground pistachios, flour, and melted butter. Can you smell that? It’s heavenly! Just make sure to be gentle here; we don’t want to knock any air out of the mixture.
Bake the Cake: Pour the batter into the prepared pan and pop it into the oven for about 20-25 minutes. Check your cake by inserting a toothpick in the center, if it comes out clean, it’s done!

Making the White Chocolate Pistachio Crunch

While the cake is baking, let’s tackle that creamy, dreamy topping.

Melt the White Chocolate: In a small microwave-safe bowl, melt the white chocolate with the whipping cream. Heat for 30 seconds, stir, then heat in additional 15-second bursts until melted. Stir in the chopped pistachios.

Once the cake is cool, spread this luscious mixture over the top like a sweet blanket!

Preparing the Raspberry Mousse

Now we move on to our fluffy mousse, which I might add, is so easy to whip up.

Blend the Berries: Blend your raspberries, sugar, and lemon juice until smooth. You want it to be like a berry puree, so keep blending until it’s combined beautifully.
Gelatin Prep: Sprinkle the gelatin over the cold water and let it sit for about 5 minutes to bloom. After that, warm it up in the microwave for a few seconds until it becomes liquid. Slowly mix it into the raspberry puree.
Whip the Cream: In another bowl, whip your cream until it forms soft peaks. Then fold it into the raspberry mixture, creating a light and airy mousse (my favorite part!).
Layer the Cake: Now, pour the raspberry mousse over your pistachio cake. Chill it in the refrigerator for at least 3-4 hours until it’s set, perfect for anticipation!

Serve it Up!

When you’re ready to dig into this gorgeous cake, slice it up and garnish with extra raspberries and maybe a sprinkle of chopped pistachios for a pretty presentation. And trust me, your family is going to flip over this!
