  • 175 grams all-purpose flour could be anywhere from 1 1/4 to 1 1/3 cup
  • 160 grams bread flour about 1 cup and 2 tablespoons
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 230 grams 1 cup unsalted butter, softened
  • 150 grams granulated sugar 3/4 cup
  • 165 grams packed brown sugar (I sometimes use 150) 3/4 cup, but VERY tightly packed**
  • 2 large eggs
  • 3/4 teaspoon vanilla
  • 255 grams chopped bittersweet chocolate or quality chocolate chips
  • 70 grams chopped milk chocolate


  • Whisk the dry ingredients (flour through salt) together in a medium size bowl. Set aside.
  • In a large mixing bowl, beat butter and sugars together until very light and fluffy, scraping down the side of the bowl as needed. Beat in the eggs, one at a time, mixing until well combined after each. Mix in vanilla.
  • Toss bittersweet and milk chocolates into the dry ingredients - mix to coat. Add dry ingredients to mixing bowl and mix until completely combined. Cover and place cookie dough into the refrigerator to chill for 24 hours.
  • When ready to bake, preheat oven to 350 degrees.
  • Scoop out about 1/4 cup worth of dough per cookie and roll each into a ball - place onto parchment lined baking sheets two to three inches apart, then flatten each slightly.
  • Bake one sheet at a time until the cookies are golden brown around the edges, yet the center is still slightly soft, about 14 to 17 minutes. Remove and place baking sheets onto a wire rack and allow cookies to cool (still on the baking sheet) for 5 to 10 minutes. Transfer cookies to the rack and allow to cool completely.

Brown sugar, like flour, can vary by weight/volume.  My brown sugar typically weighs 200 grams to 220 grams per 1 cup.  For this recipe, some recipes use 175 grams for 3/4 cup.  I use more like 150 to 165.
