Preheat oven to 325F.
Place flour, cocoa powder, and baking soda in a bowl, stir to combine and set aside.
Whip the butter and sugars until light and airy. Slowly incorporate the eggs (one at a time), vanilla, and optional teaspoon of molasses.
Mix the dry ingredients into the wet batter slowly, and then stir in your desired amount of chocolate chips.
Portion out 1-2 tablespoon scoops of batter onto a prepared cookie sheet and bake for 12-15 minutes.
After removing from oven, allow the cookies to set for one minute before placing them on a baking sheet to finish cooling.
