_________________________ Ingredients (for about 30 cookies) 225 g unsalted butter 240 g sugar 480 g flour 1 egg 15 g vanilla sugar a pinch of salt Spraying flour _________________________ Preparation time: 40 minutes + 5 hours refrigeration 1. Leave butter to soften at room temperature for 20 minutes. Mix it with the sugar and the vanilla sugar, working the ingredients with a spatula until they are very well integrated. 2. Add the egg, mix well, and add the flour and salt, previously sieved. Mix first with the spatula and then knead a couple of minutes with your hands, just to obtain a uniform dough. Form a ball shape, wrap it in cling film and allow it to stand about 4 to 5 hours in the refrigerator. 3. With the aid of a rolling pin, spread the dough onto the slightly floured work table, until approximately 1/2 cm thick. Cut the dough into circles and place them on the oven tray, previously lined with greaseproof paper. 4. Press the surface of the cookies with a mold or stencil and set aside for 20 minutes in the refrigerator. Preheat the oven to 180°C. 5. Cook the cookies in the oven for 1215 minutes or until the edges start to brown very lightly. Once cooked, remove the tray from the oven and let the cookies rest. Then place them on a rack and allow to cool completely before serving.
