Thick Chewy Chocolate Chip Cookie Bars From Cooks Illustrated Recipe 415

Steps:

• Heat oven to 325°F. Adjust oven rack to lower-middle position. Cut 18-inch length foil and fold lengthwise to 8-inch width. Fit foil into length of 13 X 9-inch baking pan, pushing it into corners and up sides of pan; allow excess to overhang pan edges. Mix flour, salt, and baking soda together in medium bowl; set aside. Whisk melted butter and sugars in medium large bowl until combined. Add egg, egg yolk, and vanilla and mix well. Using rubber spatula, fold dry ingredients into egg mixture until just combined; do not over mix. Fold in chips and turn batter into prepared pan, smoothing top with spatula. Bake until top is light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan, 27 to 30 minutes. Cool on wire rack to room temperature. Remove bars from pan by lifting foil overhang and transfer to cutting board. Cut into 2-inch squares and serve.

Steps:

• Preheat the oven to 325 degrees F (165 degrees C). Grease cookie sheets or line with parchment paper.
• Sift together the flour, baking soda and salt; set aside.
• In a medium bowl, cream together the melted butter, brown sugar and white sugar until well blended. Beat in the vanilla, egg, and egg yolk until light and creamy. Mix in the sifted ingredients until just blended. Stir in the chocolate chips by hand using a wooden spoon. Drop cookie dough 1/4 cup at a time onto the prepared cookie sheets. Cookies should be about 3 inches apart.
• Bake for 15 to 17 minutes in the preheated oven, or until the edges are lightly toasted. Cool on baking sheets for a few minutes before transferring to wire racks to cool completely.

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Whisk both amounts of flour, baking soda and salt in a bowl. Beat butter, brown sugar, and pudding mix in another bowl with an electric mixer until blended; beat in egg, egg yolk, and vanilla extract until combined. Stir flour mixture into egg mixture until just combined. Fold in chocolate chips.
• Roll the dough into 2-inch balls and place 2 inches apart onto ungreased baking sheets.
• Bake until golden brown, about 15 minutes.
