These thick chocolate chip cookies are packed with rich chocolate chunks and toasted nuts for a chewy, satisfying treat. Perfectly crisp on the outside and soft on the inside, they're sure to become a new favorite!
Whisk together the flour, cornstarch, salt, and baking soda. Set aside.
Using an electric mixer on medium speed, beat the butter, brown sugar, and sugar until light and fluffy. Add the eggs one at a time, mixing until combined. Mix in the vanilla extract.
With the mixer on low speed, gradually add the flour mixture just until combined or a few small streaks of flour remain in the dough.
Stir in the nuts and both kinds of chocolate chips.
Cover and chill the dough for 1 hour.
Divide the dough into 1/4-cup portions, and roll into balls. Cover and chill again for 30 minutes.
Preheat the oven to 400°F (200°C). Line baking sheets with parchment paper or silicone liners.
Place the dough balls on the prepared pans, leaving a few inches between the cookies. Bake one pan at a time 12 to 14 minutes, or until the cookies are golden brown.
Cool the cookies on the pans on a wire rack for 10 minutes. Then transfer them from the pans to a wire rack to cool completely or serve them warm.
Notes
