Ingredients

  • 1 1/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon fine salt
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon ground cloves
  • 8 tablespoons unsalted butter (1 stick)
  • 6 ounces bittersweet chocolate, finely chopped
  • 2 large eggs
  • 1 large yolk
  • 1 cup firmly packed light brown sugar
  • 2 teaspoons pure vanilla extract
  • 6 ounces semisweet chocolate chips
  • 6 ounces white chocolate chips

Method

  • Whisk the flour, baking powder, salt, baking soda, and cloves together in a medium bowl.
  • Melt the butter in a saucepan over medium heat.
  • Remove pan from the heat, add the bittersweet chocolate, then set aside until melted.
  • Whisk the eggs, brown sugar, and vanilla together in a medium bowl, then slowly whisk in chocolate.
  • Stir in the flour mixture to make a loose dough.
  • Don't overwork the dough.
  • Fold in the chips.
  • Cover with plastic wrap and refrigerate until firm, about 2 hours.
  • Preheat oven to 350 degrees F (or 325 if convection option is available).
  • Line a baking sheet with parchment paper.
  • Form dough into balls, about 2 inches or 1 1/2 ounces each, and put on the prepared baking sheets, leaving a couple inches between the cookies.
  • Bake until outside is crackly, but the center is still moist, about 13 to 15 minutes, or 12 in convection.
  • Cool on a rack.
