In a large bowl, combine the dry ingredients: flour, 1 cup cocoa, baking soda, and salt.
In the bowl of an electric mixer, beat 1 1/2 cups sugar, brown sugar, and 1 /12 cups butter until fluffy and light (it will take roughly five minutes).
Add the eggs, one at a time. Beat well after each addition.
Add the blended dry ingredients. Mix until there are still many streaks of flour left.
Pour in the baking chips. Now, mix just until combined. DO NOT OVERMIX.
Using a 1 1/2 Tablespoon cookie dough scoop, drop cookie dough 3 inches apart on parchment paper-lined baking sheets.
Slightly flatten with the tines of a fork.
Bake 350* for 8 to 10 minutes or until the cookies look set. DO NOT OVERBAKE.
Cool on the baking sheet for a minute so the cookies firm up enough so you can move them to a cooling rack.
