These Levain-inspired two-chip chocolate chip cookies are ultra-thick, bakery-style treats loaded with semi-sweet and dark chocolate chips. Gooey inside, golden outside—perfect for when only the best will do.
1 cup (2 sticks) cold unsalted butter, cubed
3/4 cup packed light or dark brown sugar
1/2 cup granulated sugar
2 large eggs
1 1/4 cups all-purpose flour
1 cup cake flour
2 teaspoons cornstarch
1/2 teaspoon baking soda
1/2 teaspoon baking powder
3/4 teaspoon salt
1 1/2 cups semi-sweet chocolate chips
1 cup dark chocolate chunks
Optional: 3/4 cup chopped walnuts or pecans
In a stand mixer, beat cold butter on medium speed until just broken down.
Add both sugars and mix until crumbly.
Mix in eggs one at a time, scraping the bowl as needed.
In a separate bowl, whisk together flours, cornstarch, baking soda, baking powder, and salt.
Gradually mix dry ingredients into the wet until just combined.
Fold in chocolate chips and chunks.
Form dough into 6-ounce balls and place on lined baking sheet. Chill for 30 minutes.
Preheat oven to 375°F (190°C).
Bake cookies for 12–14 minutes until edges are golden and tops are just set.
Cool for 10 minutes before transferring.
For a gooier center, slightly underbake and let rest on the baking sheet. Dough can be refrigerated or frozen for later use.
