Whisk together eggs, sugar, and brown sugar in a bowl to a fluffy mass
Add vanilla and baking powder to the sugar mixture
Add the flour, oat, and coconut to the dough
Melt the butter and add it to the dough
Chop the hazelnuts (into fine pieces) and chocolate (into medium pieces) and add it to the dough
Form balls at the size of tennis balls and put them on a sheet of baking paper on a baking pan. Sqezze the balls flat either with your hand or a table spoon with some flour on the back of it (so that it doesn't stick to the cookies)
Bake the cookies in the middle of the oven at 180 degrees C in 10-12 min
