Ingredients You’ll Need

- Pistachio flour: Provides the core nutty flavor and naturally gluten-free base for the cake’s tender crumb.
- Almond flour: Adds a subtle sweetness and helps with the cake’s light texture.
- Sugar: Balances the earthy nuttiness with just the right amount of sweetness.
- Large eggs: Bind ingredients together while providing structure and moisture.
- Unsalted butter, melted: Adds richness and a velvety finish to the cake.
- Olive oil: Enhances the moistness and brings an extra depth of flavor.
- Pistachio extract: Amplifies the nutty flavor to make every bite more vibrant.
- Salt: A pinch to highlight the sweetness and round out the flavors.

How to Make Flourless Pistachio Cake with Chocolate Ganache Recipe
Step 1: Preheat and Prepare Your Pan
Start by setting your oven to 350°F (175°C). It’s important to grease and line an 8-inch round cake pan with parchment paper. This ensures your cake releases easily after baking and keeps its beautiful shape intact.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together pistachio flour, almond flour, sugar, and salt. This step evenly distributes the dry ingredients and sets the stage for that perfect pistachio flavor infusion.
Step 3: Combine the Wet Ingredients
In a separate bowl, beat the eggs until frothy. Then add the melted unsalted butter, olive oil, and pistachio extract. This mixture brings moisture, richness, and that irresistible pistachio aroma to the batter.
Step 4: Bring It All Together
Pour the wet ingredients into the dry, mixing only until you have a smooth and uniform batter. The key here is gentle mixing to keep the texture light and tender.
Step 5: Bake to Perfection
Transfer the batter to your prepared cake pan. Smooth the top with a spatula and bake for 30 to 35 minutes. You’ll know the cake is done when a toothpick inserted in the middle comes out clean. Let the cake cool completely in the pan before moving it to a wire rack.
Step 6: Prepare the Chocolate Ganache
While the cake cools, make your ganache by heating the heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour the warm cream over the chopped dark chocolate. Let it sit for two minutes, then stir until silky smooth. Allow the ganache to cool slightly to thicken but still be pourable.
Step 7: Assemble Your Flourless Pistachio Cake with Chocolate Ganache Recipe
Once the cake is completely cool, pour the ganache over the top. Use a spatula to spread it evenly to the edges for a luscious finish. Finally, sprinkle slivered pistachios on top for a gorgeous, crunchy garnish.
How to Serve Flourless Pistachio Cake with Chocolate Ganache Recipe

Garnishes
A sprinkle of slivered pistachios adds a fresh crunch and a vibrant green contrast against the glossy chocolate ganache. For extra flair, a dusting of powdered sugar or a few edible flowers can enhance the presentation and elevate your serving experience.
Side Dishes
Serve this cake alongside a cup of freshly brewed coffee or a glass of dessert wine to complement the rich pistachio and chocolate flavors. Fresh berries or a dollop of whipped cream can also add brightness and balance the decadence in a delightful way.
Creative Ways to Present
For a special occasion, try slicing the cake into petite squares and serving it on cocktail plates with a drizzle of raspberry coulis. You can also layer the cake with whipped mascarpone for added indulgence. The Flourless Pistachio Cake with Chocolate Ganache Recipe is versatile and stunning whether served simply or fancied up.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cake well covered in the refrigerator to preserve its moisture and freshness. It will stay delicious for up to three days, perfect for enjoying a slice or two at leisure.
Freezing
You can freeze the cake without ganache for up to one month wrapped tightly in plastic wrap and stored in an airtight container. Thaw overnight in the refrigerator and then spread the fresh ganache before serving for best results.
Reheating
If you prefer your cake slightly warm, allow it to come to room temperature and then warm individual slices gently in the microwave for about 10 seconds. Avoid overheating to keep the texture and ganache perfect.
FAQs
Can I use other nuts instead of pistachios?
Absolutely! While pistachios offer a unique flavor, you can swap in hazelnut or walnut flour for a different but equally delicious twist. Just be aware the flavor profile will shift accordingly.
Is this cake gluten-free?
Yes, the Flourless Pistachio Cake with Chocolate Ganache Recipe is naturally gluten-free since it uses nut flours instead of wheat flour, making it an excellent option for those with gluten sensitivities.
Do I need a special pan for baking?
A standard 8-inch round cake pan works perfectly. Just ensure it’s greased and lined properly to avoid sticking and to maintain the cake’s neat edges.
Can I make the ganache dairy-free?
Yes, you can substitute heavy cream with coconut cream or a non-dairy creamer to create a dairy-free ganache that stays rich and smooth, pairing wonderfully with the pistachio cake.
How should I store the cake if I’m not adding ganache right away?
Store the cooled cake in an airtight container at room temperature or in the fridge. Add the ganache just before serving to maintain its fresh texture and glossy look.

Ganache Ingredients
- 1 cup dark chocolate, chopped

Garnish
- Slivered pistachios
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper to prevent sticking.
- Prepare the Cake Batter: In a large mixing bowl, whisk together pistachio flour, almond flour, sugar, and salt until well combined.

Gradually combine the wet ingredients with the dry ingredients, mixing until you achieve a smooth, consistent batter.
