Method
Preparation
- Preheat your oven to 350°F (175°C) and position the rack in the middle.
- In an electric mixer, beat the softened butter and brown sugar on medium speed for about 3 minutes until fluffy.
- Add eggs and vanilla extract, beating for an additional 2 minutes until well combined.
- On low speed, mix in baking soda and salt, then gradually add flour and cocoa powder until just combined.
- Reserve 1/4 cup of chocolate chips for topping, then mix the remainder into the batter until evenly distributed.
- Transfer the cookie batter to an ungreased 10-inch cast iron skillet, smoothing the top and sprinkling reserved chocolate chips on top.
Baking
- Place the skillet in the oven and bake for about 35 minutes, until puffy and set with a slightly firm edge.
Serving
- Allow the cookie to cool for 15-20 minutes, then cut into wedges and serve warm, ideally with a scoop of ice cream.
Notes
Cover leftovers with aluminum foil and store at room temperature for up to 3 days. For variations, try different types of chocolate or add nuts for added texture.
