Step 1

Preheat oven to 350°F (175°C). Line 2 cookie sheets or baking trays with parchment paper (baking paper).

Step 2

In a medium-sized bowl, mix together the cocoa powder, white sugar, butter and vegetable oil. Beat in egg and vanilla until fully incorporated.

Step 3

Add the flour, baking powder, and salt; stir the dry ingredients first before mixing them through the wet ingredients until a dough forms (do not over beat). Fold in the chocolate chips.

Step 4

Scoop out 1-2 tablespoonful of dough with a cookie scoop (or small ice cream scoop), and place onto prepared baking sheets. Press them down as thick or thin as you want your cookies to come out.

Step 5

Bake in hot preheated oven for 10-12 minutes. The cookies will come out soft from the oven but will harden up as they cool. (Be careful not to over bake as they will dry out.)

Step 6

Allow to cool on the cookie sheet for 10 minutes before transferring to wire racks to cool.
