Prep
- Preheat oven to 350F. Lightly grease a 10-inch cast iron skillet with butter or nonstick spray.
- In a large bowl, whisk melted butter with brown sugar and granulated sugar until well combined, about 1 minute. Whisk in the egg and vanilla until smooth and glossy.
- Add flour, baking soda, and salt. Stir with a rubber spatula until just combined and no dry streaks remain. Do not overmix.
- Gently fold in chopped Oreos and chocolate chips if using. The dough will be thick and studded with cookie pieces.
- Press dough evenly into the prepared skillet, smoothing the top. Press a few extra Oreo cookie pieces into the surface for looks if desired.
- Bake 22-26 minutes until the edges are set and golden brown but the center still looks slightly underdone. It will continue cooking as it cools. A toothpick inserted near the edge should come out clean; the center should have a few moist crumbs.
- Cool 10-15 minutes before slicing. Serve warm with vanilla ice cream and extra Oreo crumbles on top.
Notes
For the best texture, pull the skillet when the center still jiggles slightly - it sets up perfectly as it cools. No cast iron? Use a 9-inch cake pan and add 3-4 minutes to the bake time. The dough can be made ahead and refrigerated up to 3 days; let it soften 30 minutes at room temperature before pressing into the skillet.
