These thick, chewy chocolate chip cookies feature both milk and semi-sweet chocolate chips for a deliciously rich flavor and gooey center — just like your favorite bakery.
2 ¾ cups all-purpose flour
1 tsp baking soda
1 ½ tsp cornstarch
¾ tsp salt
1 cup unsalted butter, softened
1 cup packed dark brown sugar
½ cup granulated sugar
2 large eggs
1 extra egg yolk
2 tsp vanilla extract
1 cup semi-sweet chocolate chips
1 cup milk chocolate chips
Cream butter and sugars until light and fluffy.
Beat in eggs one at a time, then add the extra yolk and vanilla.
In a separate bowl, mix flour, baking soda, cornstarch, and salt.
Gradually add dry ingredients to wet mixture, stirring until combined.
Fold in both types of chocolate chips.
Cover and chill dough for at least 2 hours.
Preheat oven to 350°F (175°C) and line baking trays.
Scoop large dough balls and space evenly.
Bake 11–13 minutes, until edges are golden and centers are soft.
Let cookies rest on tray before transferring to a rack
