Method
- Heat the oven to 400°F.
- Line a rimmed 18x13-inch baking sheet with parchment paper.
- In the bowl of a stand mixer fitted with the paddle attachment, beat the cold butter, brown sugar, and granulated sugar on medium speed for 2 to 3 minutes, until creamy with no large butter chunks.
- Add the eggs one at a time, beating until incorporated after each addition and scraping down the bowl as needed.
- In a separate bowl, whisk together the cake flour, all-purpose flour, cornstarch, baking soda, and salt.
- Add the flour mixture to the mixer and mix on low just until no dry flour remains.
- Fold in the chocolate chips and walnuts until evenly distributed.
- Divide the dough into 8 equal portions, about 6 ounces each, and shape into tall, rough mounds without flattening.
- Chill the mounds on a plate for 30 minutes.
- Bake 4 mounds at a time on the prepared sheet for 12 to 14 minutes; the edges should be golden and the tops set while the centers remain soft.
- Keep the remaining dough refrigerated and let the pan cool completely between batches.
- Let the cookies cool on the pan for 15 minutes before transferring them to a wire rack.
Notes
For the tallest cookies, keep the remaining dough refrigerated while each batch bakes. Store airtight in the refrigerator for up to 5 days; freezer: yes, freeze baked cookies for up to 3 months. For a dairy-free variation, use dairy-free butter and semisweet chocolate chips.
