Ingredients You’ll Need

The beauty of this Flourless Pistachio Cake Recipe lies in its simplicity – a handful of essential ingredients come together to create a harmony of taste and texture. Each component plays a vital role, from the buttery richness to the fresh lemon zing and the fluffy airiness that keeps this cake from feeling heavy or dense.

• Unsalted butter (80 g, melted and cooled): Adds a creamy richness that binds and softens the cake.
• Pistachios, no shells and unsalted (220 g): The star ingredient; finely ground for a beautifully nutty and vibrant flavor.
• Caster or superfine sugar (160 g): Sweetens gently without graininess, blending seamlessly with the nuts.
• Blanched almond flour (20 g): Enhances the nutty profile and supports the cake’s soft texture.
• Finely grated lemon zest (1 1/2 tsp): Infuses a fresh citrus brightness that lifts the cake’s flavor.
• Large eggs (4, separated and at room temperature): Key for structure and lightness, with beaten whites providing airiness.
• Vanilla extract (1 tsp): Adds subtle warmth and depth to the flavor profile.
• Sea salt (1/4 tsp): Balances the sweetness and enhances the nut flavors.
• Baking powder (1/2 tsp): Just enough leavening to give a gentle rise without compromising the texture.
• Icing sugar (for dusting): Offers an elegant final touch for presentation and slight extra sweetness.
• Whipped cream and fresh raspberries (for serving): Provide a luscious, creamy, and tart counterpoint to the cake’s earthy richness.

How to Make Flourless Pistachio Cake Recipe

Step 1: Prepare Your Oven and Tin

Start by preheating your oven to 170 degrees Celsius (340 Fahrenheit). Preparing the cake tin properly is crucial: grease an 8-inch (20 cm) springform tin and line both the base and sides with baking paper to ensure the cake comes out effortlessly after baking.

Step 2: Melt the Butter

Melt 80 grams of unsalted butter and let it cool slightly while you get the rest of your ingredients ready. The butter should be warm but not hot when added to maintain the proper texture in the batter.

Step 3: Grind Pistachios and Sugar

Place the sugar and pistachios into a small food processor and pulse until you get a fine, sandy texture. Stir the mixture halfway through to ensure even grinding. This step releases the oils from the pistachios, giving the cake that wonderfully rich flavor.

Step 4: Mix Dry Ingredients

Transfer the pistachio-sugar mixture to a large mixing bowl. Add the blanched almond flour, lemon zest, sea salt, and baking powder. Stir these dry ingredients together so the flavors blend and the baking powder is evenly distributed.

Step 5: Combine Yolk, Butter, and Vanilla

To the dry mix, add the separated egg yolks, the cooled melted butter, and vanilla extract. Mix thoroughly, knowing the batter will be thick and rich – this is exactly what you want as the foundation for your flourless cake.

Step 6: Whip and Fold Egg Whites

In a clean, dry bowl, beat the egg whites until they form stiff peaks. To keep as much air in the batter as possible, gently fold half the egg whites into the pistachio mixture at first, then the remaining half. This delicate folding is what gives the cake its light, airy crumb while maintaining rich flavors.

Step 7: Bake Carefully

Pour the batter into your prepared cake tin and place it in the oven. Bake for 35 minutes, then loosely cover the cake with foil to prevent over-browning. Continue baking for an additional 10-12 minutes, or until a skewer inserted in the center comes out clean. The cake should have a moist yet set crumb.

Step 8: Cool and Remove

After baking, allow the cake to cool in the tin for 10 minutes. Carefully release the sides of the springform tin, and then let the cake cool completely on the base before removing the bottom. This prevents any cracking or breaking of your beautiful cake.

How to Serve Flourless Pistachio Cake Recipe

Garnishes

A simple dusting of icing sugar enhances the cake’s natural pistachio green color while adding a hint of extra sweetness. A dollop of whipped cream adds a luscious creaminess that pairs perfectly with the nutty, dense crumb. Fresh raspberries or other tart berries provide a bright contrast that really rounds out every bite.

Side Dishes

This Flourless Pistachio Cake Recipe stands beautifully on its own or alongside a scoop of vanilla bean ice cream for extra indulgence. For a lighter option, serve with a ramekin of lemon curd or fresh seasonal fruit salad to complement the citrus zest and nut flavors.

Creative Ways to Present

For a striking dessert table, slice the cake into thin wedges and arrange them on a platter dusted with edible flowers or crushed pistachios. You can also layer it in individual glass cups with whipped cream and berries for an elegant parfait-style treat. A drizzle of honey or a sprinkle of crushed toasted pistachios on top adds gorgeous texture and shine.

Make Ahead and Storage

Storing Leftovers

Wrap your leftover Flourless Pistachio Cake Recipe tightly in plastic wrap or place it in an airtight container. It will stay fresh in the refrigerator for up to 3 days, making it a convenient treat to enjoy a little bit at a time.

Freezing

This cake freezes very well if you want to prepare it in advance. Wrap it securely in cling film, then in foil, and freeze for up to 1 month. Thaw overnight in the refrigerator before serving to maintain perfect texture and flavor.

Reheating

If you prefer to serve the cake warm, gently reheat slices in a low oven (about 150 degrees Celsius) for 5-8 minutes or until just warmed through. Avoid microwaving as it can dry out the delicate crumb.

FAQs

Can I use salted pistachios instead of unsalted?

It’s best to use unsalted pistachios for this Flourless Pistachio Cake Recipe to control the salt level precisely. If using salted nuts, reduce or omit added salt to avoid an overly salty cake.

Is it necessary to separate the eggs?

Absolutely. Separating the eggs and whipping the whites to stiff peaks creates lightness and structure. Without this step, the cake would be denser and less airy.

Can I substitute the almond flour?

Almond flour contributes to the nutty flavor and texture, but if you have an allergy, finely ground hazelnuts or cashews can occasionally work. Avoid wheat-based flours since this is designed to be flourless.

How do I know when the cake is done?

Insert a skewer into the center; it should come out clean or with a few moist crumbs. The cake should spring back slightly when touched and have a golden-green hue from the pistachios.

Is this cake suitable for special diets?

This Flourless Pistachio Cake Recipe is naturally gluten-free, and if you use dairy-free butter and omit whipped cream, it can be adapted for dairy-free diets too. It’s a great dessert option for many restrictions!
