Preheat the oven at 180°C (350°F) , and prepare the baking sheet.
In a large bowl, mix the soft butter with sugar until fully incorporated, then add the egg and vanilla sugar.
In another bowl, mix the flour, baking powder and a pinch of salt.
Add the flour mixture into the butter mixture. Mix it until it forms a dough. And add the chocolate chips into it.
Then take a big nut size of the dough in the palm of your hand to form a ball, put it on the baking sheet and flatten it. When it’s done put it in the oven for around 14min, it should be a little bit gold.
