In a medium-sized bowl add flour salt and baking soda. Then whisk altogether.

On the side roughly chop your dark chocolate into medium sized chunks.

Next melted butter and added to a combined mixture of your brown and granulated sugar.

Once combined add an egg and one egg yolk in addition with some vanilla extract.

Now once that's done you can go ahead and adding the flour mixture to the wet batter and fold it in.

You can all folding your roughly chopped dark chocolates into the cookie dough making sure that they are evenly distributed.

If you're doing a container and leave into the refrigerator to rest for a few hours / completely chilled.

When you're ready to break you can go ahead and preheat your oven to 180*c and roll up Ur dough into small balls and spread them evenly across the baking tray (you could use an ice-cream scoop if wanted).

Cook for 10 minutes and 1 stone leave to cool for 30 minutes. *Believe me, it's worth the wait.*
