Whisk the butter with the sugar until pale and foamy.
3
Add the egg. Mix.
4
Add the chocolate cut in little chips and the baking powder.
5
Add finally the flour...
6
...and mix well with a spatula to obtain a dough.
7
Put this dough on a sheet of baking paper. Shape it into a sausage.
8
And give it a nice sausage-like shape. Leave to rest in the fridge for a few hours.
9
Remove the baking paper.
10
Cut 1/2 cm thick slices.
11
Put those slices on a greased baking sheet. Altern the lines so that they will have more space to bake and to reduce the possibility that they stick with each other.
12
Bake in a warm oven (180/200°C or 356/392°F).
13
Bake until it reaches the color you want. The darker the dryer. If you like then soft with a sort of uncooked middle, I recommand you take them out when the center of the cookie is still light.
14
When finished, leave them for 2 minutes before removing them them for the sheet with a metal spatula. Leave to cool. Bon Appétit !!!
