8 tablespoons (112 g) unsalted butter, roughly chopped
4 ounces bittersweet chocolate, roughly chopped
1/2 cup + 2 tablespoons (88 g) all purpose gluten free flour (I used my mock Better Batter)
1/4 teaspoon xanthan gum (omit if your blend already contains it)
1 1/2 tablespoons (14 g) cornstarch
7/8 cup (122 g) Gluten Free Bread Flour*
3 tablespoons (15 g) unsweetened cocoa powder (Dutch-processed is better, but natural will work, too)
1/2 teaspoon baking soda
3/4 teaspoon baking powder
3/4 teaspoon kosher salt
1/2 cup + 2 tablespoons (120 g) granulated sugar
10 tablespoons (140 g) packed light brown sugar
1 egg (60 g) at room temperature, beaten
1 teaspoon pure vanilla extract
10 ounces bittersweet chocolate disks
Coarse salt, for sprinkling

In a small, heat-safe bowl, place the chopped butter and chopped chocolate. Place the bowl over a small pan of simmering water, making sure the water doesn’t touch the bowl, stirring occasionally until the butter and chocolate are melted and smooth. Remove the pan from the heat and set the bowl aside to cool briefly. (Alternatively, you can melt the butter and chocolate in the microwave on 60% power in 30-second bursts.) In a large bowl, place the all purpose flour, xanthan gum, cornstarch, bread flour, cocoa powder, baking soda, baking powder, salt and granulated sugar, and whisk to combine well. Add the light brown sugar, and whisk again to combine, working to break up any lumps in the brown sugar. Create a well in the center of the dry ingredients and add the cooled butter and chocolate mixture, plus the egg and vanilla, mixing to combine after each addition. The dough will be thick. Add the chocolate disks, and mix until they are evenly distributed throughout. Wrap the cookie dough tightly in plastic wrap, and refrigerate ideally for 24 to 72 hours.
On baking day, preheat your oven to 350°F. Line two large rimmed baking sheets with unbleached parchment paper. Divide the dough into 10 balls, each nearly 3 1/2 ounces (the size of generous golf balls), and place them at least 6 inches apart from one another on the prepared baking sheets. Press the balls of dough into 3/4-inch thick disks, and sprinkle the tops lightly with coarse salt. Place in the preheated oven and bake until mostly set, but still soft toward the center (about 15 minutes). The cookies will spread to about 5-inches in diameter. Allow to cool on the baking sheet for at least 10 minutes, or until set.
