Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius).

In an electric mixer fitted with the dough hook, cream the oil, margarine, and brown sugar together until creamy and lighter in color.

In a separate bowl, mix the cocoa, flour, baking soda, baking powder, and salt.

Lower the mixer speed and add the dry ingredients, followed by the vanilla extract and eggs.

Once mixed, add the chocolate chips and mix by hand to incorporate fully.

Put sugar in a shallow bowl.

Form dough into approximately one-inch balls and roll in the sugar.

Place dough balls two inches apart on a Gefen Parchment-lined baking sheet.

Bake for 13 minutes — cookies will harden as they cool.
