Preheat oven to 180ºC (356ºF). Line a baking tray with parchment paper, set aside.
Combine flour, cocoa, coconut, baking powder and baking soda together in a mixing bowl. Mix well and set aside.
In a large mixing bowl with a hand beater or using a stand mixer, add softened coconut oil, coconut sugar and milk. Beat until well combined and fluffy.
Add egg and vanilla, beat until light and smooth, approx. 15-20 seconds.
Gradually beat in flour mixture until it begins to form a soft dough.
Slowly beat through chocolate chips, macadamias and marshmallows.
Form into a soft dough, wrap in cling film and refrigerate for 30 minutes.
Remove from refrigerator and form into balls/cookies. Approx. 2 tablespoons worth each. Place onto prepared tray, pressing down on them slightly. Repeat with remaining dough.
Bake for 12-15 minutes or until cracks appear on top and marshmallows are golden.
Remove and cool on tray for 10 minutes.
Transfer to a wire rack to cool completely.
Serve and Enjoy!
