|two versions of cocoa powder|
In making this double chocolate chunk cookies, I like to spice up the chocolate flavor by adding cocoa powder in addition to chocolate chunks. Instead of using the common natural cocoa powder (like Hershey's), I used the alkalized version which is milder, less bitter, darker and more intense in flavor. Cocoa powder is made by removing much of the cocoa butter from the chocolate liquor after the bean is fermented and roasted. The resulting powder is acidic in nature. The Dutch invented a method using alkalies to raise the pH, making it more soluble, less harsh and darker in color. Most European cookbooks prefer this type of cocoa powder.
I used the recipe from Thomas Keller's Bouchon Bakery, which is famous for its cookies.

1) Combine flour, salt, baking soda and cocoa powder in a bowl. Set aside.
2) Put brown sugar, molasses and sugar in another bowl and mix until there are no lumps.

4) Add the sugar mixture and mix for 3-4 minutes until fluffy. Scrape down the sides of the bowl.
5) Add the egg and mix for 20-30 seconds until combined.
6) Add the flour in two additions, mixing on low for 15-30 seconds after each.
7) Add the chocolate chunks and mix until combined, then refrigerate the dough for 30 minutes.
