Makes 24 cookies (2 ounces each)
2 1/8 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon kosher salt
1 1/2 cups regular semisweet chocolate chips
1 cup large bittersweet chocolate chips
1 1/2 cups walnuts, finely chopped
1 cup (2 sticks) unsalted butter, room temperature
1 cup light or dark brown sugar, tightly packed
1/2 cup white sugar
2 teaspoons vanilla extract
1. Heat oven to 375° F.
2. Sift flour, baking soda, and salt. Set aside.
3. Mix together chocolate chips and chopped nuts. Set aside.
4. All medium speed unless otherwise noted: In a standing mixer, with the paddle attachment, cream the butter and sugars until well mixed and light. Scrape down the sides. Add one egg. Mix for 5 seconds. Scrape down the sides. Add second egg. Mix for 5 seconds. Scrape down the sides. Add vanilla. Mix for 5 seconds. Scrape down the sides.
5. You’re going to add the sifted flour mixture in 4 batches, stopping before adding the final batch. For the first 3 batches, mix at low speed just to combine, scraping down the sides between each addition. When you get to the final batch of flour, add the chocolate chip/nut mixture. They will get a bit crushed. That’s okay. Mix until there’s barely a trace of flour visible. Don’t over-mix. Sometimes, it’s better to be safe and do the final bit of mixing by hand.
6. Set up a sheet pan with a silpat or parchment paper. Bake one tray at a time or they will all cook at different rates. Make them spherical, not flat. The cookie
