Prepare the dough:

01.  Mix the flour, sugar, yeast and a pinch of salt in the Sail salad bowl.

02.  Add the eggs, warm milk and melted butter. Knead until a soft, homogeneous dough forms.

Incorporate flavors:

03.  Add the chocolate, hazelnuts and orange zest to the dough, distributing the ingredients well.

Leavening:

04.  Form a ball with the dough, cover with a cloth and leave to rise in a warm place for 2 hours, or until doubled in size.

Shape the cake:

05.  Shape the dough into a doughnut shape (a circle with a hole in the middle) and place it on the previously buttered WonderGrill without the silicone handles.

06.  Leave to rest for another 30 minutes.

Baking:

07.  Brush the cake with the beaten egg and bake in a preheated oven at 180 °C for 25-30 minutes, or until golden brown.

08.  Remove, leave to cool and, if desired, sprinkle with icing sugar before serving.
