How to Make Flourless Pistachio Cake with Chocolate Ganache

Step 1: Prepare the Pistachios

Start by finely grinding the raw pistachios in a food processor until they reach a coarse, flour-like texture. Be careful not to over-process into a paste; the right consistency ensures a tender yet structured cake.

Step 2: Whip Eggs and Sugar

In a mixing bowl, beat the eggs and sugar together until pale and fluffy. This aeration is crucial for giving the cake lightness despite the absence of flour.

Step 3: Combine Ingredients

Gently fold the ground pistachios and melted butter into the egg mixture. Add the vanilla extract and a pinch of salt to enhance flavors, then mix until everything is just combined—overmixing can lead to a dense texture.

Step 4: Bake the Cake

Pour the batter into a greased or parchment-lined springform pan and bake at 325°F (160°C) for about 25-30 minutes. The cake should be set but still moist to keep its melt-in-your-mouth quality.

Step 5: Make the Chocolate Ganache

Heat the heavy cream gently until steaming, then pour it over chopped dark chocolate. Let sit for a minute before stirring until smooth and glossy; this silky ganache will be poured over the cooled cake.

Step 6: Assemble and Chill

Once the cake is completely cool, spread the ganache evenly on top. Chill the entire cake for at least an hour to allow the ganache to set and the flavors to meld beautifully.

Pro Tips for Making Flourless Pistachio Cake with Chocolate Ganache

• Use fresh pistachios: Fresh nuts ensure vibrant flavor and texture—avoid pre-salted or roasted types.
• Beat eggs properly: Thoroughly whisk eggs and sugar to incorporate air, essential for a light crumb.
• Mind the bake time: Avoid overbaking to keep the cake moist and tender inside.
• Chop chocolate finely: Smaller pieces melt more smoothly into the cream for a flawless ganache.
• Chill before serving: Cooling the cake allows flavors to deepen and the ganache to firm up for perfect slicing.

How to Serve Flourless Pistachio Cake with Chocolate Ganache

Garnishes

Enhance the beauty and flavor by sprinkling chopped pistachios, edible flowers, or a dusting of powdered sugar on top. Fresh berries also add a lovely pop of color and brightness against the rich chocolate.

Side Dishes

Pair this cake with a dollop of whipped cream or a scoop of vanilla bean ice cream to complement its dense nuttiness. A fresh berry compote or light citrus salad can also cleanse the palate between bites.

Creative Ways to Present

Serve individual slices on colorful plates with contrasting garnishes or cut bite-sized squares for an elegant dessert platter. For celebrations, add decorative chocolate curls or gold leaf for a stunning finish.

Make Ahead and Storage

Storing Leftovers

Keep any leftover cake covered tightly in the refrigerator; it will stay fresh for up to 4 days while maintaining moistness and flavor.

Freezing

Wrap the cake or individual slices securely in plastic wrap and plunge into a freezer bag. Freeze for up to 2 months—thaw overnight in the refrigerator before serving to retain texture.

Reheating

Since this cake is best enjoyed cool or at room temperature, avoid reheating. Instead, let frozen slices thaw slowly for the best taste and texture.

FAQs
