2 1/8 c Flour
1/2 t table salt
1/2 t baking soda
12 T unsalted butter, melted and cooled slightly (I don't use unsalted butter because I never buy it - salted butter works just fine in this recipe when I use it!)
1 c brown sugar
1/2 c sugar
1 large egg
1 large egg yolk
2 t vanilla
1-2 c chocolate chips (I used an entire 11oz bag of Nestle swirled chips as well as 1/2 c. of Nestle Semi-Sweet chips)
Heat oven to 325 degrees. Adjust oven racks to upper- and lower-middle positions. Mix flour, salt, and baking soda together in medium bowl; set aside.Either by hand or with electric mixer, mix butter and sugars until thoroughly blended. Mix in egg, yolk, and vanilla. Add dry ingredients; mix until just combined. Stir in chips.
Form dough into balls using a spoon and place on cookie sheets (I lined with parchment paper). I formed little dough balls to create mini sized cookies, so use your judgement based on how big you want your cookies to be.
Bake, reversing cookie sheets’ positions halfway through baking, until cookies are light golden brown and outer edges start to harden yet centers are still soft and puffy, 15 to 18 minutes (As you know, everyone's oven is different. I baked my mini's for about 11-12 minutes and they came out perfectly). Cool cookies on cookie sheets. Serve or store in airtight container.
