Ingredients
Method
- Preheat the oven to 350°F (175°C) and butter an 8-inch cast iron skillet. In a large bowl, whisk the melted butter, brown sugar, and granulated sugar until glossy. Whisk in the egg and vanilla until smooth.
- Add the flour, cocoa powder, baking soda, and salt to the bowl. Fold with a spatula just until no dry streaks remain, then stir in about 2/3 cup of the chocolate chips.
- Spread the batter evenly in the skillet and press the remaining chocolate chips on top. Bake for 18 to 22 minutes until the edges are set and a toothpick inserted near the center comes out with moist crumbs.
- Let the cake cool in the skillet for 10 minutes, then slice into wedges and serve warm.
Notes
Let the cake rest in the pan for at least 10 minutes before slicing so the center can set; it will firm up as it cools. If you like an extra gooey center, pull it a minute sooner.
