Mix the butter, sugar, brown sugar, vanilla in a stand mixer until fluffy. For approximately 5 minutes.
Add the mixture one egg at a time and continue beating.
Sift all the dry ingredients and add the dough. Add the chocolate.
Portion the dough into 40-gram balls (it is good to use a glove or the ice cream scoop, as the dough is a little soft) and place on baking sheets with parchment paper or greased with release agent.
Leave 3 cm space between the balls.
Bake in a preheated oven at 180 degrees until the edges are golden and the center is soft.
