Chocolate chip cookies

What to do in a rainy day? Make chocolate chip cookies and boost your moral and the one of your dear ones to the maximum :)
Classic recipe, that similar you can find all around the web, but I like to keep good recipes once found, so here it is the one that I prefer...



Ingredients (for about 30 big cookies)
250gr butter
100gr brown sugar
100gr white sugar
vanilla flavor
2 large eggs
350gr plain flour
1 teaspoon of baking powder or (bicarbonate) soda
1/2 teaspoon of salt
200 gr of good dark chocolate (chips or chunks)

Procedure

Preheat the oven to air and 170 degrees of Celsius.
Whisk the butter with the sugars until whiten. Add the eggs and continue. Add the flour and the rest apart from chocolate and make a nice soft dough (adjust the flour to the feeling of the dough).
Add the chocolate chips or chunks and mix to go evenly all over your dough.
Make small or big dough balls (depending on your preference for chocolate cookies :) and flatten them. Put them in oven trays (you will need 2) that you have covered with the special baking paper.
Cook for about 10-15min depending on the size of your cookies (the bigger, the longer...).
Let them cool and then stock the remaining ones (of course, some will be already eaten in the meantime ;) in a tin box for cookies.
