Step 1: Prepare the Cake Pans

Preheat the oven to 350°F (175°C).

Grease and line two cake pans with parchment paper.

Step 2: Mix the Dry Ingredients

In a bowl, whisk together:

Flour
Ground walnuts
Baking powder
Salt

Set aside.

Step 3: Prepare the Batter

Beat the egg yolks with half of the sugar until pale and creamy.

Mix in:

Vanilla extract
Lemon zest
Melted butter
Milk

Gradually fold in the dry ingredients.

In another bowl, beat the egg whites until soft peaks form.

Gradually add the remaining sugar and beat until glossy stiff peaks form.

Carefully fold the egg whites into the batter in three additions, keeping as much air as possible.

Step 4: Bake

Divide the batter evenly between the prepared pans.

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.

Cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

Step 5: Prepare the Buttercream

Beat the softened butter until smooth and fluffy.

Gradually add:

Powdered sugar
Cocoa powder

Mix until smooth.

Add:

Melted dark chocolate
Vanilla
Heavy cream

Beat until light, creamy, and spreadable.

Step 6: Assemble the Cake

Place one cake layer on a serving plate.

Spread a generous layer of chocolate buttercream over the top.

Add the second cake layer.

Frost the top and sides with the remaining buttercream.

Press toasted chopped walnuts onto the sides of the cake.

Decorate the top with chocolate shavings and whole walnut halves.

Step 7: Chill and Serve

Refrigerate the cake for 1 hour before slicing to allow the buttercream to set.

Bring it to room temperature for about 20 minutes before serving for the best flavor and texture.
