Ingredients
For the Walnut Cake
2 cups (200 g) finely ground walnuts
1 cup (125 g) all-purpose flour
6 large eggs, separated
¾ cup (150 g) granulated sugar
1 teaspoon vanilla extract
1 teaspoon baking powder
1 pinch of salt
Zest of 1 lemon (optional)
For the Buttercream Filling
1 cup (225 g) unsalted butter, softened
1 cup (120 g) powdered sugar
2 tablespoons milk
1 teaspoon vanilla extract
2 tablespoons finely ground walnuts
For the Decoration
½ cup (50 g) chopped walnuts
Powdered sugar, for dusting
Melted dark chocolate, optional
Instructions
Step 1: Prepare the Oven and Cake Pan
Preheat the oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
Make sure the walnuts are finely ground rather than chopped into large pieces. This helps create a more delicate cake texture.
Step 2: Beat the Egg Yolks and Sugar
In a large mixing bowl, beat the egg yolks with half the granulated sugar until the mixture becomes pale, thick, and creamy.
Add the vanilla extract and optional lemon zest, mixing until combined.
Step 3: Prepare the Dry Ingredients
In a separate bowl, combine the ground walnuts, flour, and baking powder.
Stir thoroughly so the ingredients are evenly distributed.
Step 4: Whip the Egg Whites
In a clean bowl, beat the egg whites with the salt until soft peaks form. Gradually add the remaining sugar and continue beating until the whites become glossy and hold firm peaks.
The whipped egg whites help give the walnut cake its light texture.
Step 5: Combine the Batter
Gently fold the walnut mixture into the egg yolk mixture.
Add the whipped egg whites in two or three additions, folding carefully to preserve as much air as possible. Avoid vigorous mixing, which can make the cake dense.
Step 6: Bake the Cake Layers
Divide the batter evenly between the prepared pans and smooth the tops.
Bake for approximately 20–25 minutes, or until the cakes are lightly golden and a toothpick inserted into the center comes out clean.
Allow the cakes to cool in their pans for about 10 minutes, then transfer them to a wire rack to cool completely.
Step 7: Make the Buttercream
Beat the softened butter until light and creamy.
Gradually add the powdered sugar, followed by the milk and vanilla extract. Continue beating until the buttercream becomes smooth and fluffy.
Fold in the finely ground walnuts for extra flavor.
Step 8: Assemble the Torte
Place one cooled cake layer on a serving plate. Spread the walnut buttercream evenly over the top.
Place the second cake layer on top and gently press it into position.
Spread a thin layer of buttercream over the top and sides if desired, reserving some for decorative piping.
Step 9: Decorate and Chill
Press the chopped walnuts around the sides or sprinkle them over the top. Add a light dusting of powdered sugar or drizzle with melted dark chocolate for an elegant finish.
Refrigerate the cake for at least one hour to help the filling set. Before serving, allow it to stand at room temperature briefly so the buttercream softens.
Tips for the Perfect Hungarian Walnut Torte
Use fresh walnuts. Freshly ground walnuts provide the best flavor and aroma.
Avoid overmixing. Folding the egg whites gently helps keep the cake light.
Cool the cake completely. Warm cake layers can cause the buttercream to melt.
Choose finely ground walnuts. They create a smoother texture and distribute the flavor evenly.
Allow time to chill. Refrigeration helps the filling set and makes slicing easier.
Balance the sweetness. A little lemon zest or dark chocolate can complement the richness of the walnuts.

Walnuts are an important ingredient in Hungarian confectionery, appearing in many traditional desserts served at family gatherings and festive occasions. Hungarian bakers have long used ground walnuts in cakes, pastries, sweet rolls, and layered desserts.
