INGREDIENTS
For the dough:
130 g of butter
300 g of icing sugar
3 eggs
120 ml of milk
2 tablespoons of natural yogurt
50 g of cocoa powder
1/2 pack of baking powder
140 g of flour
1 pack of pudding hazelnut flavored powder
For the mascarpone cream:
500 g of mascarpone
200 ml of whipped cream
1 pack of strengthening cream
50 g of icing sugar
For the chocolate and hazelnut cream:
200 ml of whipped cream
80 g of chocolate with hazelnuts
100 g of dark chocolate
For decoration:
200 ml of
Nutella whipped cream to taste

Dough:
Mix together the flour, baking powder, cocoa and pudding powder. Halve the mixture.
In another bowl, cream the butter with the icing sugar until creamy, add the eggs and mix everything well.
Add half the dry mixture and half the milk, mix and then add the remaining flour and milk. Finally, add the yogurt and mix everything well again.
Place the dough in a buttered and floured 28cm springform pan and bake at 180°C for about 45 minutes.
Unmold the finished cooked pasta base, let it cool and cut it in half lengthwise. Put one half back in the mold and the other half aside.
Mascarpone cream:
Mix the whipped cream with the sugar and whipped cream and beat until stiff. Gradually add the mascarpone and continue mixing briefly, but not for too long.
Walnut and chocolate cream:
Place the whipped cream in a suitable saucepan, add the chocolate pieces (both types) and place the saucepan in a bain-marie. Mix with a whisk until the chocolate melts and the mixture begins to solidify. Then remove from the heat and leave to cool, stirring occasionally.
Spray the pastry base in the springform pan with half the milk and spread half the mascarpone cream on top. Spread the chocolate cream on top and finally the remaining mascarpone cream. Place the second sheet on top and drizzle with the remaining milk. Place in the refrigerator for several hours, preferably overnight. Once the cake has cooled, remove it from the mold and spread the whipped cream all over the cake and decorate it with a sufficient quantity of Nutella or melted nut chocolate.
