Mix all the ingredients in the mixer bowl with the flat beater on medium speed, until you have a homogeneous dough. Shape the dough into a cylindrical shape and place it in the fridge until it is firm.
Remove from the fridge and spread lightly with water. Roll the dough on a pan with granulated sugar and cut it into slices. Place the slices on a non-stick pan and bake in a preheated oven at 160° C, until they get a golden colour, for about 30 minutes.
TIP:* We can dip cookies in melted chocolate and let it cool.* We can crumble the cookies over ice cream, yogurt or pastry cream.* We can make a cookie sandwich with a filling of our choice.
* If you do not have a pan with non-stick coating can use baking paper.
