Skillet Cookie

Preheat the oven to 375°F (190°C). Coarsely chop the chocolate bar and set aside ¼ cup (60 mL) of the chocolate.
Add the butter, brown sugar, granulated sugar, salt, egg and vanilla to the Deluxe Stand Mixer. Set to CREAM for 1 minute and 50 seconds. Press Start.
When finished, press X. Add the flour and baking soda to the bowl. Select MIX and set to 45 seconds. Press Start. When 10 seconds remain, pause, add all but the reserved chocolate from step 1 into the dough and continue mixing for 5 seconds.
Spread the dough onto the bottom of the 10" (25-cm) Cast Iron Skillet. Top with the reserved chocolate and bake for 25–28 minutes, or until the edges are dark brown and a toothpick inserted in the center comes out clean.
Let the cookie cool in the pan for at least 5 minutes before cutting. Serve with ice cream, if desired.
