Ingredients
  

  • ¾ cup unsalted butter
  • 1 cup granulated sugar
  • 2 tbsp dark brown sugar
  • 2 tsp vanilla
  • 1 large egg (both yolk and white)
  • 1 large egg yolk (save the extra white for another use)
  • 2 cups all-purpose flour, spooned and leveled
  • 6 tbsp Dutch-processed cocoa powder
  • 1 ½ tsp corn starch
  • ¾ tsp baking soda
  • ¾ tsp coarse Kosher salt (if using table salt, use half the amount)
  • 1 cup white chocolate chips (plus a few extra to sprinkle on top)
  • ½ cup dark or semi-sweet chocolate chips (plus a few extra to sprinkle on top)

Instructions
 

  • In a saucepan, melt the butter over medium heat, then remove from the heat.
  • In a large bowl, whisk together the melted butter with the granulated sugar, brown sugar, vanilla extract, egg and egg yolk, until smooth.
  • In a separate bowl, combine the flour, cocoa powder, corn starch, baking soda and salt.
  • Add the dry ingredients to the liquid ingredients, using a wooden spoon to stir the dough together just until all the flour is incorporated. Let cool for 10 minutes.
    Since you're making the dough with hot, melted butter, the dough needs to cool before you add the chocolate chips, or the chips can melt and make a mess.
  • Stir the white and dark chocolate chips into the cooled dough - it will be stiffer now than before, and you may need to use your hands to get all the chocolate chips worked in.
  • Use a cupcake/ice cream scoop with a release lever to portion the dough into 18 equal portions. Roll each portion of cookie dough into a ball, then flatten slightly between your hands into round disks about 1/2-3/4 inch thick. Cover the dough with a piece of plastic wrap to keep it moist while waiting to bake.
  • Preheat the oven to 350 F, and position a rack in the center of the oven. Line a large baking sheet with parchment baking paper.
  • Bake 6 cookies at a time, leaving three inches between each on the baking sheet. Bake the cookies for 8 minutes. They should be just set around the edges, with the centers still underdone. Do not over-bake these cookies, as chocolate cookies become very dry and crumbly when they're over-baked. Cool on the pan for 2 minutes, then transfer to a cooling rack to cool completely. If you like, add a few more chocolate chips to the tops of the hot cookies, for a pretty finish.
    TIP: For perfectly round cookies, immediately after taking the pan of cookies out of the oven, use a round cookie cutter (one that's larger than the baked cookies), and "scoot" it around the hot cookies. This pulls in the uneven edges for a beautifully round cookie. You have to do this quickly, before the edges fully set.
  • Finish baking the remainder of the cookie dough. Cool the cookies completely, then store in an airtight container at room temperature for up to 3 days, or in the freezer for up to 3-6 months.

Notes

Leftover cookies should be stored in an airtight container for up to 3 days, or frozen for 3-6 months.  I like to keep a piece of sandwich bread in my cookie jar - it keeps the cookies so soft!
