  • 1/2 cup (100 grams) granulated sugar
  • 3 cups bread flour (376 grams) (see note about flour types)
  • 1 1/4 teaspoon salt (decrease to 3/4 if using salted butter)

  • 1 teaspoon baking powder
  • 1-2 teaspoons cornstarch**
  • 2 cold eggs, extra large beaten in a separate bowl (110-112 grams)
  • 1 teaspoon vanilla extract
  • 1 1/2 cups extra dark chocolate chips such as Guittard extra dark (in the shiny red bag)

  7. Put the formed dough balls in a zipper bag and chill overnight. This will help them hold their shape.
  8. If you are using convection, preheat to 350℉ convection and bake cookies for 18-20 minutes or until the top starts to crack. Allow the cookies to cool for at least an hour before serving.
  9. If you are using a regular oven, bake at 375 for about 18 to 20 minutes or until tops start to crack.
  10. Let cool for about 5 minutes on the cookie sheet, then remove and finish cooling on a rack.
Notes
I've tested these with all kinds of flour combinations and like bread flour the best because it makes the cookies fatter and gives them a harder shell. You can use bread flour, a combination of bread and all-purpose, bread mixed with cake -- whatever works best in your kitchen. As for the butter, I used to always make these with Plugra or HEB European style, but when I started testing with other brands of European style butter I had mixed results. Land o Lakes seems to work just fine, though the cookies might spread a tiny bit more. Adding dried milk makes the cookies a tiny bit softer, but it's not a crucial ingredient. Cornstarch curbs the spread a little bit, but I think a good chill overnight does a better job.
