Chocolate chip cookie bars

Set the oven to 350.

Whisk the flour, cornstarch, baking soda and salt together in a large bowl and set aside.

In a second bowl whisk the granulated sugar, brown sugar and the melted cooled butter for about 30 seconds until smooth and thick.

Whisk in the eggs and the vanilla for about a minute, until smooth.

Stir the dry into the wet with a spatula until almost combined, leaving some flour visible.

Stir in the chocolate chips, holding back about a quarter cup, until the last of the flour disappears.

Line the eight by eight inch pan fully with parchment, spread the batter in and level it with a spatula.

Sprinkle the reserved quarter cup of chocolate chips over the top.

Bake about 50 to 55 minutes, until a skewer in the centre comes out with a few crumbs and the edges are set. Cover loosely with foil at the 30 minute mark. Subtract a few minutes for a fudgier result.

Cool, finish with a sprinkle of flaked sea salt if you like, lift out of the pan and cut into pieces.
