Mix the flour, cocoa, baking powder, salt and sugars together well then mix in the chocolate chips
Melt the butter
Mix the eggs together with the vanilla
Mix all the ingredients together in a bowl until well combined and there is no dry ingredients left. Cover the bowl in plastic and chill for several hours or even a few days. If you want to make them straight away spread the mixture on a tray and freeze for 20 minutes to chill down
When you are ready for cookies, roll balls of dough the size of a golf ball and put onto a lined baking tray. (You may have to leave the dough on the bench for a few minutes to let it warm enough to roll balls) These need to be baked from cold for the best fudgy results Leave 8cm distance between each.
Bake for 12 minutes
The cookies will only just be baked around the outside and the centre will still be soft when touched. They may appear uncooked. Once cool they will firm up.
Cool on the tray till starting to firm up. Then cool on a rack for at least 1/2 an hour before eating. They will be fudgy in the middle and crunchy on the outside
The cookies can be baked till cooked through but they are quite hard and crunchy
