180 g of butter (you can replace it with a vegetable product such as Pasticceria di Vallèe)
10 g of baking powder
3 teaspoons of honey
for decorating optional
powdered sugar
PROCEDURE
Blend the hazelnuts with the 00 flour and the icing sugar.
Melt the butter and let it cool.
Prepare the dough by mixing the hazelnut, flour and sugar mixture with the sifted yeast, honey and egg whites (not whipped!) in a large bowl.
Add the melted butter and mix with a spatula. Cover the bowl with cling film and place in the refrigerator for half an hour.
Butter and flour the mold or line it with baking paper. Pour the mixture into the mold and bake in a preheated oven at 180 ° for about 30 minutes (do the toothpick test).
Remove from the oven and let cool.
Spread the icing sugar on the surface if you want. You can use a decorative stencil, it does not have to be for food, the important thing is to wash it very well since it will support the food, do not use scented soaps but something neutral or bicarbonate.
