Preheat oven to 180°C and line/grease a 22cm square baking tray (9 x 9″).
In a medium bowl mix together ground flax with 3 tablespoons water, stir and set aside.
To a large bowl, add all dry ingredients and mix together (except choc).
To flax mixture, add maple, vanilla and tahini.
Add wet ingredients to dry ingredients and mix well. The batter will be thick! But don’t stress.
Fold in half the chocolate chunks, then scrape batter into the baking tray and spread it out evenly. Top with the remaining chocolate chunks.
Bake for 25 minutes (fan-assisted) to 30 minutes (regular oven).
Allow to cool completely before cutting. Then devour, mindfully.
