Preheat the oven to 160°C or 320°F, and line a baking tray with baking paper.
Combine the dry ingredients (except for the chocolate) in a medium-sized bowl.
In another bowl, whisk the wet ingredients (except for the egg).
Add the egg and a pinch of sea salt to the wet mixture and whisk for another 3 minutes, until the mixture is light and bubbly.
Fold the wet ingredients into the dry mixture, and combine.
Stir in the finely chopped dark chocolate or cocoa nibs.
Roll tablespoon-sized amounts of dough into balls and flatten slightly on the lined baking tray.
Bake for 10-15 minutes, until the cookies are golden around the edges.
Allow the cookies to cool down for a few minutes.
Enjoy!
