Dark Chocolate Cookies

Bahan-bahan (30 porsi)

• 1/2 cup all-purpose flour
• 1/3 cup unsweetened cocoa powder
• 1/2 teaspoon salt
• 1/4 teaspoon baking powder
• 6 ounces bittersweet chocolate coarsely chopped (I used 60%; the darker the chocolate, the more intense the cookies will be)
• 4 tablespoons unsalted butter (cut into 6 pieces)
• 2 large eggs at room temperature
• 2/3 cup granulated sugar
• 1 teaspoon pure vanilla extract
• 12 ounces semi-sweet chocolate chips (about 2 cups)
• Flaky sea salt (such as Maldon or Fleur de Sel (optional))
