These bakery-style Levain Chocolate Walnut Cookies are thick, gooey, and loaded with dark chocolate chunks and toasted walnuts. A rich treat with crisp edges and a soft center.
1 cup (2 sticks) cold unsalted butter, cubed
¾ cup light brown sugar, packed
½ cup granulated sugar
2 large eggs (cold)
2¼ cups all-purpose flour
1 tbsp cornstarch
½ tsp baking soda
½ tsp baking powder
½ tsp kosher salt
2 cups bittersweet chocolate, chopped
1½ cups walnuts, toasted and roughly chopped
Preheat oven to 400°F. Line baking sheets with parchment paper.
Beat cold butter with both sugars until just combined and crumbly.
Add eggs one at a time, mixing until just incorporated.
In a separate bowl, whisk flour, cornstarch, baking soda, baking powder, and salt.
Gradually mix dry ingredients into wet until combined.
Fold in chocolate and walnuts.
Divide dough into 6 oz balls and place on prepared sheets.
Bake 9–11 minutes, until edges are golden and centers are soft.
Cool on sheet for 10 minutes before transferring.
For thicker cookies, chill the dough for 1–2 hours before baking. Use pecans or hazelnuts for variation. Freeze shaped dough for future baking.
