Place dry ingredients (sugar, coconut, vanilla and cacao powder) in a bowl and stir until well combined. Whisk the egg and egg white together and add to dry ingredients. Mix well. The mixture should not be too wet. Cover the bowl and place in the fridge for half an hour.
Pre-heat the oven to 320 (F). Using wet hands, make small balls, place 2 inches apart on a baking tray lined with parchment paper and and bake for 10-15 minutes or until golden brown.
Allow to cool in the tray.
These little macaroons can be frozen. To serve, simply thaw them.
