2 cups plus 2 Tbsp all-purpose flour
1/2 tsp baking soda
1/2 tsp salt
12 Tbsp (1 1/2 sticks) unsalted butter, melted & cooled until warm
1 c brown sugar, packed
1/2 c granulated sugar
1 large egg plus 1 yolk
2 tsp vanilla extract
Directions:-Adjust oven racks to upper & lower -middle positions & heat oven to 325. Line cookie sheets with parchment paper.-Whisk dry ingredients together; set aside.-With electric mixer, or by hand, mix butter & sugars until thoroughly combined. -Beat in egg, yolk and vanilla until combined. -Add dry ingredients & beat at low speed just until combined. Stir in chips.-Roll scant 1/2 cup dough into ball. Holding dough ball in fingertips of both hands, pull into 2 equal halves. Rotate halves 90 degrees and, with jagged surfaces facing up, place formed dough onto cookie sheet, leaving ample room between each ball.-Bake, reversing position of cookie sheets halfway through baking, until cookies are light golden brown and outer edges start to harden yet centers are still soft & puffy (about 17 minutes in my oven). -Cool cookies on sheets until able to lift without breaking and place on wire rack to cool.
