Levain Style Chocolate Chip Walnut Cookies are thick, bakery-inspired cookies with crisp golden edges, gooey centers, rich chocolate, and toasted walnuts.
1 cup unsalted butter, cold and cubed
3/4 cup brown sugar
1/2 cup granulated sugar
2 large eggs
3 cups all-purpose flour
1 tablespoon cornstarch
1 teaspoon baking powder
1/2 teaspoon baking soda
1 teaspoon fine sea salt
2 cups semi-sweet chocolate chips or chunks
1 cup walnuts, lightly toasted and chopped
Preheat oven to 400°F and line baking sheets with parchment paper.
Mix cold butter with both sugars just until combined.
Add eggs one at a time, mixing briefly after each addition.
In a separate bowl, whisk flour, cornstarch, baking powder, baking soda, and salt.
Gradually mix dry ingredients into the wet mixture until a thick dough forms.
Fold in chocolate and walnuts.
Divide into six large portions and shape into tall mounds.
Place on baking sheets and bake for 9 to 11 minutes.
Let rest on the baking sheet for 10 minutes before serving.
Do not overmix the dough.
Bake at high temperature for crisp edges and soft centers.
Cookies will continue to set as they cool.
