Add in the chopped chocolate.
Although the original recipe calls for milk chocolate chips, Taylor Swift makes it her own by using rough chunks of dark chocolate. So, of course, we did the same!
Chop 2 cups of dark chocolate into small chunks and use a rubber spatula to mix it into the dough. Reserve some to sprinkle directly on top for little pools of chocolate. Points for presentation. Now, you can make the recipe as individual cookies just like Taylor, but we decided to do it bigger and better by transforming it into a skillet.
