2 cups chocolate chips, semisweet, milk chocolate, or combination, divided
Instructions
Preheat the oven to 350 F and grease a 10-by-15-inch jelly roll pan.
Combine the flour, salt, and baking soda in a bowl; stir and set aside.
In a mixing bowl with an electric mixer, beat the butter for about 1 minute, until creamy. Add the brown and granulated sugars and continue beating on medium-high speed for about 3 minutes, until light and fluffy.
Add the eggs, one at a time, beating after each addition. Beat in the vanilla.
Add the dry ingredients and mix on low speed until well blended.
Fold in 1 1/2 cups of the chocolate chips.
Spread the dough in the prepared baking pan. A metal spatula works well for spreading the thick dough.
Bake the chocolate chip cookie bars in the preheated oven for about 22 to 26 minutes, until golden brown.
