Preheat oven 150ºC and line two cookie trays with baking paper then set aside. Sift flour, cacao powder, baking powder, baking soda, and salt into a bowl. Whisk these dry ingredients until they are well combined, then set the bowl aside.
In another bowl, use an electric hand mixer to beat coconut oil and coconut sugar until the mixture is creamed; it should be light and fluffy in texture.
Pour in maple syrup, egg, vanilla and beat on medium speed until these wet ingredients are well combined.
Gradually pour the dry ingredients into the bowl of wet ingredients, beating each batch (on low-medium speed) until the mix combines into a "semi-solid" cookie dough.
Add the raw cacao nibs and white chia seeds and stir until they are distributed evenly through the cookie dough.
Use a table-spoon to scoop out balls of dough (or get grubby and use your hands); roll them into a ball and place them 2 inches apart from each other on the cookie tray.
Bake for about 12-15 minutes, then remove from the oven.
Let them sit on the tray for 2-3 minutes before transferring to a cooling rack (where they will solidify as the coconut oil in the dough cools).
