It’s a sunny afternoon, and you’ve just pulled a stunning flourless pistachio cake topped with smooth chocolate ganache from the oven.
As the rich smell wafts through your kitchen, you start to think about what will go perfectly with this treat. For me, the first thought is pairing this cake with a good cup of coffee. A nice espresso or a creamy cappuccino can really elevate the experience.
If you’re feeling a little adventurous, a dollop of whipped cream flavored with a hint of cardamom or orange zest complements the cake beautifully.
Or perhaps you prefer a fresh berry compote on the side. Think tart raspberries or sweet blueberries; their acidity cuts through the richness of the chocolate ganache, leaving your taste buds dancing with joy.
And let’s not forget a scoop of homemade vanilla bean ice cream. Absolutely divine.

Ingredients for Flourless Pistachio Cake With Chocolate Ganache
For Cake:
6 large eggs, at warm room temperature
2 cups finely ground pistachio meal
1 ¼ cups caster sugar
¾ teaspoon fine sea salt flakes
¾ teaspoon natural pistachio essence
2 tablespoons corn starch
¾ cup blanched almond meal
10 tablespoons unsalted butter, diced
1 teaspoon freshly grated orange peel
2 tablespoons extra virgin olive oil
1 tablespoon freshly squeezed lemon juice
1 teaspoon vanilla bean paste
For Ganache Topping:
1 cup heavy whipping cream
5 oz dark chocolate (60-70% cocoa), finely chopped
1 oz milk chocolate (30-35% cocoa), finely chopped

How to Make Flourless Pistachio Cake With Chocolate Ganache
Step 1: Preheat and Prepare
First, preheat your oven to 350°F (175°C). Greasing your cake pan liberally is essential. I like to use a springform pan, as it makes removing the cake a breeze once it cools.
Line the base with parchment paper for an extra layer of assurance.
Step 2: Beat the Eggs
In a large mixing bowl, crack the six eggs. Whisk them until they’re fluffy and pale. This process incorporates a lot of air and is vital for creating a light cake. Keep whisking—it should take about 5 minutes.
Step 3: Gradually Add Sugar
Slowly sprinkle in the caster sugar while continuing to whisk. The mixture will start to become even lighter in color. Keep going until the sugar has dissolved completely.
Step 4: Incorporate the Ingredients
Next, add in the pistachio essence, freshly grated orange peel, lemon juice, and olive oil. Stir gently to combine.
Step 5: Fold in the Dry Ingredients
In another bowl, whisk together the finely ground pistachio meal, almond meal, corn starch, and salt. Slowly fold these into the egg mixture, being careful to maintain the airy texture you’ve created.
Step 6: Melt the Butter
In a small saucepan, melt the diced butter over low heat. Once melted, allow it to cool slightly before folding it into the cake batter.
Step 7: Bake the Cake
Pour the batter into your prepared cake pan. Bake for approximately 25-30 minutes, or until a toothpick inserted into the center comes out clean. You want a slight wobble but not a gooey center.
Step 8: Cool the Cake
Remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Run a knife around the edges to ensure it doesn’t stick, then release the sides of the springform pan. Let it cool completely on a wire rack.
Step 9: Prepare the Ganache
While your cake cools, it’s time to make the chocolate ganache. In a small saucepan, heat the heavy cream until it begins to simmer. Remove from heat and immediately add the chopped dark and milk chocolate. Let it sit for a minute to melt before stirring until smooth and glossy.
Step 10: Assemble
Once the cake has cooled completely, pour the ganache generously over the top. Feel free to let some drip down the sides – the messier, the better!
Step 11: Chill and Serve
For the best texture, let the ganache set at room temperature for about 30 minutes, or pop it in the fridge for a quick chill. Now it’s ready to be sliced and served.
Recipe Notes
Eggs: Using room temperature eggs helps with better aeration when you whisk them.
Pistachio Meal: You can make your own by blending raw pistachios until finely ground. This gives a fresher flavor.
Caster Sugar: This is finer than regular sugar and dissolves easily, giving a smooth texture to your cake.
Butter: Opt for unsalted to control the overall saltiness in your cake.
Ganache: Feel free to play around with the chocolate ratios. A higher cocoa content provides a more intense flavor.
Recipe Variations
If you want to mix things up, consider these variations:
- Nut Free: Substitute pistachio meal with sunflower seed meal for a nut-free alternative.
- Fruity Twist: Add chopped dried fruits like apricots or figs to the batter for a chewy texture.
- Spiced: Sprinkle in some cardamom or cinnamon for a warm, spicy note.
- Coffee Infusion: Replace some of the heavy cream in the ganache with brewed espresso.
- Lemon Blueberry: Fold in fresh blueberries into the batter for a tart contrast to the sweetness.
- Caramel Drizzle: Drizzle some homemade or store-bought caramel sauce over the ganache.
