Please use a scale to weigh your flour, sugar and oats, do not rely on cup measurements as this recipe requires accurate measurements.
MAKE A FLAX EGG. Add the ground flaxseed and water to a small dish, stir together and set aside for 5 minutes to thicken up and make a ‘flax egg’.
1 tbsp flaxseed, 3 tbsp water
MIX THE WET INGREDIENTS. In a medium mixing bowl, add the melted coconut oil, sugar, vanilla and flax egg.
80 g coconut oil, 120 g coconut sugar, 1 tsp vanilla extract
STIR IN THE DRY INGREDIENTS. Add the oat flour, bicarbonate of soda and 1/4 tsp salt and stir together.
160 g oat flour, 1/2 tsp bicarbonate of soda, 1/4 tsp salt
Stir in rolled oats and dark chocolate chips.
70 g rolled oats, 80 g chocolate chips
SHAPE THE COOKIES. Use a small ice cream scoop (approx 1 heaped tbsp) to scoop out 15 cookies (approx 36g each). Roll the dough into balls and place on a tray, or in a freezer-proof dish, lined with baking paper.
Press a few extra chocolate chips gently into the top of each dough ball (not essential, it just makes them look extra tasty once they’re baked!).

FREEZE the cookie dough balls for at least 30 minutes (this is an essential step - do not skip!) (note 2).If you prefer, you can make these cookies in advance and store them in the freezer until you’re ready to bake. Freeze them in a lined tray as directed and once they’ve frozen solid (after approx 30 mins), transfer the cookie dough balls to a freezer proof bag. Then, when you’re ready, bake as directed below (note 3). PREHEAT THE OVEN to 170°C fan (190°C conventional / 375°F / gas mark 5), whilst the dough is chilling, and prep a second baking tray by lining it with baking paper.
IT’S TIME TO BAKE! Remove the cookie dough balls from the freezer, spread them out over the two lined trays and bake for 10 minutes, in the preheated oven.
If the cookies look rounded on top when they come out of the oven, use the flat bottom of a mug or ramekin to gently press them down, as soon as they come out of the oven. Don’t press them thin, just flatten the surface slightly so they are not too rounded/domed.
Sprinkle a little sea salt on top, whilst the cookies are still warm, and then leave to cool before enjoying.

STORING & ENJOYING. If you like a softer (but still slightly chewy) cookie texture, store at room temperature. If you prefer a crisp but chewy texture, store in the fridge (I personally enjoy them straight from the fridge). Store in an airtight container for up to 3 days.
