thin crunchy chocolate chip

Almost Joanne Chang’s Very Thin and Crunchy Chocolate Chip Cookies

These are thin and crunchy cookies that can be made large or small. The original recipe called for a temperature of 350 degrees F, but I bake the cookies at a lower temperature for a longer time to get the texture evenly crunchy. I've used both 325 and 300 successfully. I recommend baking a couple of test cookies to see how the cookies bake in your own home oven.

  • 1 cup 228 grams unsalted butter, at room temperature (2 sticks), slightly cool butter
  • 1 cup superfine sugar 200 grams
  • ½ cup light brown sugar 100 grams
  • 1 egg at room temperature (50 grams)
  • 3 tablespoons plus 1 teaspoon water
  • 2 teaspoons vanilla extract
  • 2 cups unbleached all purpose flour 260 grams (see note)
  • 1 teaspoon salt I use Morton kosher (measures like table salt)
  • 1 teaspoon baking soda
  • 2 cups semisweet or bittersweet chocolate chips 1 1/2 cups


  • With an electric mixer, beat the butter and sugar for about 5 minutes.
  • Add the egg, water, and vanilla and beat for 2 to 3 minutes, scraping side of bowl well, until thoroughly combined.
  • In a separate bowl, mix together the flour, salt, and baking soda. Add the chocolate chips to the flour mixture and stir to coat. Using lowest speed of stand mixer (or by hand without the mixer if you used a handheld), gradually add the flour and chip mixture and stir until combined.
  • Portion the dough into 16 quarter cup (approx) portions, press them down slightly, set them on dinner plates, and cover with plastic. Chill for about 4 hours or until ready to bake.
  • When ready to bake, press the portions into disks about 3/4 inch thick.
  • Preheat oven to 325 degrees. Line one or two baking sheets with parchment paper.
  • To determine the best heat for these cookies, you may want to bake 2 or 3 cookies first just to get the timing right.
  • Arrange some of the dough rounds on a parchment lined baking sheet spacing 4 inches apart and bake in the 325 oven until they are evenly browned. This should take around 20 to 25 minutes, but check at 15.
  • If your oven runs hot or you are still getting cookies that are brown around the edges and underdone in the middle, try using 300 degrees and baking for a longer time (25 to 30 minutes).
  • Remove the baking sheet from the oven and set the sheets on wire racks to cool for 10 minutes. Transfer the cookies to the racks to cool completely. Bake the remaining dough in the same way.
  • Store cookies in the freeze to keep them crunchy.


I used 260 grams flour.  If you are comparing this recipe to one of the other versions, you may notice that the other version calls for 2 cups/280 grams of flour  For some people, 2 cups of flour weighs 280 grams.  My 2 cups weighed 260 so I'm sticking with 260.  This is just an example of why weights are more accurate than volume when baking.  
You can make these large or divide the dough pieces into smaller bits and make tiny cookies.  If making the cookies smaller, you'll need to check them at 12 to 15 minutes.
