• ¼ cup (28 g) corn starch
• 2 teaspoons baking soda
• ¾ teaspoon salt
• ½ teaspoon ground cinnamon

• Parchment paper or non-stick baking mats

Instructions

1. Preheat the oven to 350°F. Line 2 baking sheets with parchment paper or non-stick baking mats. Set aside.
2. In a bowl, whisk together the flour, corn starch, baking soda, salt, and cinnamon; set aside.
3. In a large bowl, using an electric mixer, beat the butter, brown sugar, and sugar until light and fluffy, about 5 minutes. Scrape sides of the bowl as needed.
4. Add eggs, one at a time, mixing well after each addition. Stir in the vanilla.
5. Reduce mixer speed to low, slowly add the flour mixture and mix until just combined. 
6. Fold in the dark chocolate chips, semisweet chocolate chips and the walnuts.
7. With a medium cookie scoop (#40 or #50/about 1½ tablespoons), portion out the cookie dough. Place 2 inches apart on the baking sheet. 
8. Bake cookies for 9–14 minutes or until the edges are slightly golden. 
9. Remove from the oven and let cool on the baking sheet for 2–5 minutes before transferring to a wire rack to completely cool.
10. Store cookies in an airtight container. Freeze for longer storage.

Note: For nut-free cookies, replace the 1 cup of nuts with 1 cup of chocolate chips.
