Ingredients

- 230g butter, room temperature

- 320g of flour

- 100g of sugar

- 1 teaspoon of vanilla extract

- a pinch of salt

- white sugar to decorate

In a bowl put the soft butter and the sugar.

Beat them until fluffy. Add 1 teaspoon of vanilla extract.

Add the sifted flour all in once.

Mix first with a mixer and then with your hands until you form a ball.

Wrap it with plastic and let it cool in the refrigerator for at least half an hour. Then divide the dough into 3 parts.

Roll each part to get a 3cm diameter roll.

Wrap them with plastic paper and let them cool in the freezer for half an hour. When they are really cold and hard take them out of the freezer.

In a plate put some white sugar and roll the cilinder so the sugar will attach uniformely on it.

Cut the dough with a knife into 1cm thick biscuits. Place on an oven tray with some baking paper. Bake in the oven for 15 min at 200°C (400F).

Let them cool at room temperature. Serve cold.
