Take 180g of powdered sugar, 10 g of baking powder and 60 g of cocoa and mix.
Add the soft butter and RUB into the crumb with a mixer.
Two eggs lightly whisk with a fork with one bag of vanilla sugar. Gradually pour into the bowl of the mixer. I bring it to a uniform state.
Add flour and stir.
The dough is very sticky. I shift it in a container or a bag and put it away for the night in the refrigerator.
I wear gloves (so it is more convenient to form balls) and begin to roll balls the size of a walnut ( it is not necessary more, in an oven they will grow as it turned out at me), I roll in powdered sugar.
Send in the oven for 10-12 minutes at 190 degrees.
The aroma of chocolate chip cookies for the whole house!
