Toll House cookie bars are buttery, soft and chewy chocolate chip cookie bars inspired by the classic original Nestlé Toll House chocolate chip cookie recipe.
In a large mixing bowl, whisk in the cooled melted butter with the light brown and granulated sugars until well combined. Whisk in the eggs and vanilla extract until smooth and well combined.
Stir the dry ingredients into the wet until just combined. I like to do this about ½ of the dry ingredients at a time. Fold in most of the chocolate chips. Reserve about ½ cup (85 g) for topping the cookie bars.
Press the cookie dough into the prepared pan. Use a flexible spatula to smooth the chocolate chip cookie dough evenly across the pan. Top with the reserved chocolate chips.
Bake for about 15 - 20 minutes or until the pan of cookies is a light golden brown and the edges are slightly pulled away from the sides of the jelly roll pan. Cool the bars in the pan to room temperature, slice and enjoy!
