Add the egg and vanilla extract and mix in.
Sift in the flour, baking powder and cocoa and mix to combine.
Lastly, mix in the chocolate chips.
Roll tablespoonfuls of dough into balls and arrange on the tray allowing a little room for spreading.
Flatten each ball slightly with the palm of your hand.
