The best of both worlds - a chocolate chip cookie and a brownie - baked in a skillet for the best dessert!
Preheat oven to 350ºF.
If your cast iron skillet is well seasoned you probably don’t need to grease it…if it’s not well seasoned or you want to be sure the cookie comes out easily, lightly grease your skillet. (I use a 10″ skillet).
In a medium bowl, mix together brownie mix following directions on box. Set aside.
In a stand or electric mixer, beat the butter and sugars until light and fluffy.
Add egg and vanilla, continue to beat until well combined.
Add in the salt and baking soda, beating until mixed in.
Gradually add in the flour, then the chocolate chips.
Pour brownie batter into prepared skillet.
Add cookie dough, in slightly flattened chunks, on top of brownie batter (see photo above).
Bake for 35-40 minutes or until top is just turning golden and the dough jiggles just slightly when you gently shake the pan.
Let cool slightly. Serve while still warm for the ultimate treat! (Store leftovers in an airtight container. To freeze, let cool completely. Cut into pieces, and store in freezer in airtight container).
