1 1/4CupChocolate chips (semisweet or bittersweet)
3/4CupWalnuts or pecans (toasted and chopped)optional
Instructions
Preheat oven to 375 degrees.
Prepare cookie sheet with parchment paper.
Whisk flour and baking soda together in bowl and set aside.
Melt 10 tablespoons of butter in 10-inch skillet over medium-high heat. Continue to cook, swirling constantly, until butter has dark brown color and nutty aroma.
Transfer browned butter to bowl and mix-in remaining 4 tablespoons of butter.
Whisk in brown sugar, granulated sugar, vanilla and salt.
Whisk in egg and yolk for 30 seconds until smooth and no lumps remain.
Let mixture rest for 3 minutes
Whisk for 30 seconds and let rest 3 minutes. Repeat this step 2 more times.
Using spoon, or rubber spatula, fold in flour mixture just until combined.
Stir in chocolate chips and nuts (if wanted).
Roll 3 tablespoons of dough into a ball and place 2 inches apart on prepared cookie sheets.
Bake for 10-12 minutes. Remove from oven when edges are just starting to turn color and center is still soft.
Notes
This recipe makes about 16 cookies if using 3 tablespoons per cookie. This size gives you a cookie with perfectly crisp edges and a chewy center.
Using 2 tablespoons per cookie yields 24+ cookies and you get a more uniform texture throughout the cookie.
I recommend chilling the dough for at least 30 minutes before baking. This is especially true if your dough seems thin and loose. The dough should get thicker as you go through the whisking and resting steps. But if your butter is too warm, or you are baking on a hot day, your dough may not get as thick and this is where chilling can help so that your cookies don't turn out flat.
