The Macadamia Nut Cookies

• 200gr (0.9cup – 7.2oz)flour
• 110gr (0.49cup – 3.9oz) sugar
• 130gr (0.6cup – 4.8oz) butter
• 1 egg
• 1 egg yolk
• 1tsp vanilla extract
• 100gr (0.44cup – 3.5oz) macadamia nuts

METHOD:

1. Knead together flour, sugar and butter, then add eggs, vanilla extract and finally, macadamia nuts (better if you use knife to avoid them crumble).
2. Form a ball and wrap it in a polythene bag, place in the fridge for at least 1 hour.
3. After this time, take the the pastry and, on a floured surface, roll it out with a rolling pin at half centimeter (¼ inch) thick, and cut out biscuits with your favourite cutter.
4. I used a round one with a diameter of 5cm (2 inch)  to make 18 biscuits.
5. Place them on a baking sheet covered with parchment paper and bake at 160°  (310°F) for 20 minutes.
6. Cool down a wire rack.
7. Enjoy Macadamia Nut Cookies.
