Your favorite chewy chocolate chip cookies just got easier! These chocolate chip cookie bars have the chewy texture you love in an easy-to-portion bar form.
Preheat oven to 325°F. Line (1) 9x13 inch baking pan with foil, leaving about 1 inch of the foil extending over the edges of the pan. The extra foil will create handles that you can use to lift the bars from the pan. Set pan aside.
In a medium bowl, whisk together the flour, salt and baking soda. Set aside.
In a large bowl, stir together the melted and cooled butter and sugars. Stir in the egg and egg yolk and vanilla until smooth. Add the flour mixture, stirring until no dry bits remain. Fold in 1 cup of the semisweet chocolate chips.
Turn cookie dough into prepared pan and use a spatula or clean hands to spread the dough into an even layer. Evenly distribute remaining chocolate chips on top and press them gently into the cookie dough.
Bake in preheated oven for 25-30 minutes. Allow bars to cool before serving.
