Cost:
Ingredients:
- Butter 200g
- 00 flour 500g
- Sugar 200g
- 3- 2 egg yolks and 1 whole
- Nutella / jam
- About half a bag of yeast 8gr
- Liomone or orange zest
- Pinch of salt
preparation:
We begin with the preparation of the pastry. Place in a bowl the sugar and butter softened at room temperature. Work the ingredients with an electric mixer or a planetary, until dough is smooth. At this point, add the eggs and continue to mix well. Add the flour baking powder and salt previously sifted and stir until the dough is soft and smooth.
As regards the form I used a pasta bowl round creating discs and on half of the disks with the help of a mold (in this case bell) I created hole. Now put the chocolate, but if you want even jam, on smooth discs and then superimpose the disc with the hole by making a slight pressure above and across the border to adhere well the two parties. Bake at 180 ° for 20/25 minutes. Before serving, wait 5 minutes for it to cool well.
