Ingredients You'll Need:

This recipe makes a generously sized gateau, perfect for sharing (or not!).

For the Pistachio Sponge:

• 6 large eggs, separated
• 1 ½ cups (190g) caster sugar
• 1 cup (125g) ground pistachios
• 2 tablespoons all-purpose flour
• ½ teaspoon baking powder
• Pinch of salt

For the Pistachio Buttercream:

• 1 cup (2 sticks) unsalted butter, softened
• 3 cups (360g) powdered sugar
• ½ cup (60g) ground pistachios
• 2-3 tablespoons milk
• 1 teaspoon pistachio extract (optional, for extra intense flavor)
• Green food coloring (gel is recommended for vibrant color)

For the Garnish (optional):

• Whole pistachios
• Chocolate shavings
• Fresh berries

Step-by-Step Instructions:

Making the Pistachio Sponge:

1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You can also line the bottom with parchment paper for easier removal.

2. Whisk Egg Whites: In a clean, grease-free bowl, whisk the egg whites until stiff peaks form. This is crucial for a light and airy sponge.

3. Combine Egg Yolks and Sugar: In a separate bowl, whisk together the egg yolks and sugar until pale and creamy.

4. Gently Fold: Gradually fold the egg yolk mixture into the egg whites, being careful not to deflate the mixture.

5. Add Dry Ingredients: Gently fold in the ground pistachios, flour, baking powder, and salt until just combined. Overmixing will result in a tough sponge.

6. Bake: Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

7. Cool: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

Making the Pistachio Buttercream:

1. Beat the Butter: In a large bowl, beat the softened butter until light and fluffy.

2. Add Sugar Gradually: Gradually add the powdered sugar, beating until smooth and creamy.

3. Add Pistachios and Milk: Add the ground pistachios, milk, and pistachio extract (if using). Beat until well combined.

4. Add Color: Add green food coloring, a little at a time, until you achieve your desired shade of green.

Assembling the Gateau:

1. Level the Cakes: Once the cakes are completely cool, use a serrated knife to level the tops if necessary, ensuring a flat surface for even frosting.

2. Frost the Layers: Place one cake layer on a serving plate or cake stand. Spread a generous layer of pistachio buttercream on top. Carefully place the second cake layer on top and frost the entire gateau with the remaining buttercream.

3. Decorate: Decorate your gateau with your chosen garnish – whole pistachios, chocolate shavings, and fresh berries all add a beautiful touch.

Tips for Success:

• Use High-Quality Pistachios: The flavor of the pistachios will greatly impact the overall taste of the gateau. Use shelled pistachios and grind them yourself for the freshest flavor.
• Don't Overmix: Overmixing the batter can result in a tough sponge. Mix only until the ingredients are just combined.
• Let it Cool Completely: Ensure the cakes are completely cool before frosting to prevent the buttercream from melting.
• Get Creative with Decoration: Experiment with different garnishes to personalize your gateau.

This pistachio gateau is a stunning and delicious dessert that's sure to impress. Enjoy the process and savor the delicious results! Remember to share your creations using #PistachioGateau!
