½ cup unsweetened cocoa powder
1 cup white granulated sugar
½ cup melted butter
3 tablespoons vegetable oil
1 egg
2 teaspoons pure vanilla extract
1 ⅓ cups all purpose flour or plain flour
½ teaspoon baking powder
 ½ teaspoon salt
 ⅓ cup semi sweet chocolate chips add more if desired

• Preheat oven to 350°F (175°C). Line 2 cookie sheets or baking trays with parchment paper (baking paper). 
• In a medium-sized bowl, mix together the cocoa powder, white sugar, butter and vegetable oil. Beat in egg and vanilla until fully incorporated.
• 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.
• 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. 
• 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.)
• Allow to cool on the cookie sheet for 10 minutes before transferring to wire racks to cool.

Tip: Take the cookies out of the oven while they are still slightly soft in the centre and let them cool. This will provide you with that gooey, soft texture.
