1 1/2 Sticks Unsalted Butter
2 c + 2 Tbl. Unsifted, Bleached, All Purpose Flour
1/2 ts Baking Soda
1/2 ts Salt
1 c Light or Dark Brown Sugar
1/2 c Granulated Sugar
1 lg Egg + 1 Yolk
2 ts Pure Vanilla Extract
1 1/2 c Chocolate Chips
Place a rack in the middle of the oven. Preheat oven to 325 F. Temperature is critical so use an oven thermometer to verify the correct oven temperature and adjust as necessary. Melt the butter in a small saucepan and set aside to cool until it's lukewarm. In a large bowl, whisk the flour, baking soda, and salt. Do not sift. Place both sugars in a medium mixing bowl. Pour melted butter into sugar and mix until completely blended. Add egg, yolk, and vanilla extract. Mix until blended. Add flour mixture and mix until blended. Add chocolate chips. Mix just until chips are evenly distributed.
Line 11 x 17 cookie sheets with parchment paper. Don't use waxed paper. It's too flammable.
Baking Instructions: Using a scant 1/4 cup of cookie dough, roll a ball in the palms of your hands. Grab the ball with the fingertips of both hands and pull the dough into two pieces resembling half moons. Rotate the halves so the two jagged/flat sides point toward the ceiling and push the two halves together. You'll now have a cookie with a jagged top surface (they look like little tree stumps). Place the cookies (about 6 per sheet) onto the cookie sheets. Put cookies in oven and bake for 15 minutes.
Start checking for doneness after about 13 minutes and every two minutes thereafter. They are done when they are turning light golden brown and the edges are starting to get dry and firm while the centers are still soft. Cool cookies completely on their cookie sheets.
