Thick, gooey Levain Chocolate Walnut Cookies packed with dark chocolate chunks and toasted walnuts. Inspired by the famous New York bakery.
225g unsalted butter, cold and cubed
150g brown sugar
100g white sugar
2 large eggs
350g all-purpose flour
2 tsp cornstarch
1 tsp baking powder
½ tsp baking soda
1 tsp salt
300g dark chocolate chunks
200g walnuts, roughly chopped
Cream cold butter with brown and white sugar until just combined.
Add eggs one at a time, mixing gently.
In a separate bowl, whisk flour, cornstarch, baking powder, baking soda, and salt.
Add dry ingredients to wet and mix until a thick dough forms.
Fold in chocolate chunks and walnuts.
Divide dough into 8 large mounds. Chill for 30 minutes.
Preheat oven to 200°C (392°F).
Bake cookies for 11–13 minutes until edges are golden and centers are just set.
Cool on tray for 10 minutes before transferring to a rack.
Toast walnuts for deeper flavor. Cookies are best enjoyed warm. Dough freezes well for later use.
