Before you start, gather all your ingredients. Having everything measured and ready will make the process smoother.

Kitchen Tools You’ll Need

Food processor (to grind the pistachios)
Mixing bowls
Whisk
8-inch round cake pan
Parchment paper
Small saucepan (for the ganache)
Spatula

2. Baking the Flourless Pistachio Cake

1: Preheat the Oven

Preheat your oven to 350°F (175°C).
Grease and line an 8-inch round cake pan with parchment paper.

2: Grind the Pistachios

If you haven’t bought pre-ground pistachios, use a food processor to grind them until they have a fine, flour-like consistency.
Be careful not to overprocess, as this can turn them into pistachio butter.

3: Mix the Dry Ingredients

In a large mixing bowl, whisk together:

2 cups of finely ground pistachios
½ cup of granulated sugar
¼ cup of unsweetened cocoa powder
½ teaspoon of baking powder
¼ teaspoon of salt

4: Mix the Wet Ingredients

In a separate bowl, whisk together:
- 4 large eggs
- ½ teaspoon of vanilla extract
Slowly pour the egg mixture into the dry ingredients, stirring until fully combined.

5: Bake the Cake

Pour the batter into the prepared pan and smooth the surface.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

3. Making the Chocolate Ganache

1: Heat the Cream

In a small saucepan, heat 1 cup of heavy cream over medium heat until it begins to simmer.
Remove it from the heat immediately (don’t let it boil).

2: Melt the Chocolate

Place 8 ounces of chopped semisweet chocolate in a heatproof bowl.
Pour the hot cream over the chocolate and let it sit for 5 minutes.

3: Whisk Until Smooth

After 5 minutes, whisk the mixture until the chocolate is fully melted and the ganache is smooth.
Stir in 1 teaspoon of vanilla extract (optional) for added depth of flavor.

4. Assembling the Cake

1: Pour the Ganache Over the Cake

Once the cake is completely cool, place it on a serving plate.
Pour the chocolate ganache over the top, letting it drip down the sides for a stunning effect.

2: Let the Ganache Set

Allow the ganache to set at room temperature for 20-30 minutes before serving.

3: Garnish (Optional)

Crushed pistachios for crunch
