I got the recipe from Ricette della Nonna and I will now share with you the whole procedure.
Mix 10 grams of yeast, 75 grams of flour and a little warm milk into a ball and let it rise for 30 minutes.
When it has risen, add 250 g. flour, 2 eggs, 2 grams of yeast. Mix well, then add 100 grams of sugar. Mix again, then add 60 g. of soft butter.
After about 2-3 hours it should look like this
Now put it in the mixer and add 2 whole eggs, and 3 egg yolks, together with about 250 grams of flour. Mix well, then add 100 grams of sugar, mix again then add 100 grams of butter. Finally add 150 grams of raisins and about 100 grams candied peel, a teaspoon of grated lemon rind and a pinch of vanilla. Let it rise for 2 or 3 more hours.
It should then look like this.
Now place it in the paper container and let it rise again for 2 or 3 hours.
When it has risen well, bake it at 200° C for 5 minutes, make a cross on top, add a tablespoon of butter and cook for 10 more minutes. Then lower the temperature to 180°C and cook for 45 minutes.
