Mix the flax seed with 1.5 tbsp water and let it sit for 5 mins. Add the syrup, molasses, vanilla extract and oil, mix until well combined.

Add ¾ cup flour and the rest of the dry ingredients and mix until the mixture is a stiff batter. Fold in the chocolate pieces and refrigerate for at least an hour. Preheat the oven to 180 c.

Use a spoon to scoop out mixture and shape into 1.5 inch balls.

Place on baking sheet 2 inches apart. Sprinkle with extra coarse salt for salted flavour. Bake for 12 to 13 mins or until cookies have spread and are starting to turn golden on the edges.

Remove from the oven and let cool for 10 mins.
