This is actually what I learn from Soo Suen.
What you need,
195g of flour,
113.5g of butter,
1/2 teaspoon of soda,
100g of sugar.
And also the accessorizes like beaters, cookies cutters bowls and so.
What you'll do is,
1, Mix the sugar with butter evenly,
2, Mix the flour in with soda,
3, Mix the egg in,
4, After mixing them evenly, it will turn into a dough then roll them flat to about 3mm-5mm[depends what you like] and put it in the freezer approximately 10 minutes.
5, Cut them with cookies cutter and bring it to bake. [before baking, preheat the oven]
6, 170 degree Celsius and bake it about 15minutes or when it turns gold.
