Quick Hazelnut Cake

This is the kind of cake you make when you want something comforting but still a little special. Hazelnuts bring warmth and depth, chocolate adds softness, and the filling ties everything together without being heavy. It’s not a show-off cake — it’s a cake you actually want to eat, slice after slice, with coffee or a quiet afternoon pause.

Ingredients

Cake Batter

• 1/2 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1 teaspoon vanilla extract
• 4 large eggs, separated
• 1/2 cup all-purpose flour
• 1 teaspoon baking powder
• 1 cup ground hazelnuts
• 1/2 cup chopped hazelnuts
• 1/3 cup finely grated dark chocolate
• Pinch of salt
• 2 tablespoons milk
• 1 teaspoon lemon zest (optional, for freshness)

Creamy Filling

• 1 1/4 cups whole milk
• 1/2 cup unsalted butter, softened
• 2 tablespoons powdered sugar
• 2 tablespoons hazelnut spread or vanilla pudding powder
• 1 teaspoon vanilla extract

Decoration

• 1/3 cup chopped hazelnuts
• Handful of whole toasted hazelnuts
• Optional: chocolate shavings or light cocoa dusting

Instructions

1. Preheat the oven to 350°F. Grease and line a 10-inch (26 cm) round cake pan with parchment paper.
2. Cream the butter and sugar until light and fluffy. Add vanilla extract. Beat in the egg yolks one at a time, mixing well after each.
3. In a separate bowl, whisk together flour, baking powder, salt, and ground hazelnuts. Gradually fold this mixture into the batter.
4. Stir in chopped hazelnuts, grated chocolate, milk, and lemon zest if using.
5. In a clean bowl, beat egg whites until stiff peaks form. Gently fold them into the batter in two additions, keeping the mixture airy.
6. Spread the batter evenly into the prepared pan and smooth the top.
7. Bake for 38–42 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the cake for 10 minutes, then remove from the pan and let cool completely on a rack. Slice horizontally into two layers.

Filling & Assembly

1. Warm the milk slightly and whisk in the pudding powder or hazelnut spread until smooth. Let cool to room temperature.
2. Beat the butter with powdered sugar until creamy, then blend in the cooled mixture and vanilla extract.
3. Spread about one-third of the filling over the bottom cake layer.
4. Place the second layer on top and gently press. Cover the top and sides with the remaining cream.
5. Decorate with chopped and whole hazelnuts. Add chocolate shavings if desired.

Baker’s Note

You can swap the filling for a simple vanilla cream or lightly sweetened whipped cream if you prefer something lighter. This cake also tastes even better the next day, once the flavors settle.
