Chocolate & Hazelnut Gianduja Cake

This cake celebrates the classic Turin marriage of hazelnut and chocolate (Gianduja). The oil content of the hazelnuts and the cocoa butter of the chocolate form an incredibly rich, aromatic blend. Roasting is an essential step: it brings out the 'Nutella-like' character of the hazelnut, without which this would just be a simple nut cake.

Instructions

1

Preheat the oven to 180°C. Line the tin. Melt the chocolate and butter over steam.

Tip: Butter helps the chocolate melt evenly and gives shine.
2

Beat the eggs with the sugar until very fluffy (approx. 8 minutes).

Tip: Lots of air counteracts the weight of the hazelnuts.
3

Mix the lukewarm chocolate into the eggs. Sift in the flour, baking powder, salt, and fold in the ground hazelnuts.

Tip: Grind the hazelnuts finely, but be careful not to turn them into butter (oil separation)!
4

Pour into tin, bake for 30-35 minutes (skewer test). Cool completely.

Tip: Hot cake is crumbly, cold cake is sliceable.
5

Whip the cream with the icing sugar. Fold in the remaining hazelnuts (if any, or leave for the top).

Tip: The lightness of whipped cream suits the dense cake.
6

Decorate the cake with cream and whole hazelnuts. Chill for 30 minutes.

Tip: Chilling sets the cream.

Recipe FAQ

The cake didn't rise.
Hazelnuts are heavy and oily, weighing down the foam. Use enough baking powder and beat the eggs very well!
How do I peel the hazelnuts?
Roast them in the oven or a pan, then rub them in a tea towel. The skin comes off, and the flavour becomes more intense.
