Gooey, decadent, and rich double chocolate chip cookie skillet. This recipe is simple, easy to make, and will be your new favorite weeknight treat and ideal valentines dessert.
Preheat the oven to 350°F. Grease a 8" cast iron skillet or cake pan with non-stick cooking spray.
In a large bowl whisk together melted butter and sugars until creamy. Add milk, peanut butter, and vanilla extract. Whisk to combine.
Add flour, cocoa powder, corn starch, espresso powder, baking powder and soda, and salt. Use a wooden spoon or spatula to combine until a soft dough forms. Fold in chopped chocolate.
Evenly spread cookie dough into the prepared skillet or pan. (Optional): Top with more chopped chocolate. Bake for 22-25 minutes until top is soft to touch and edges have formed a crust. That is ok if it looks slightly underdone, that means its gooey in the center! Cool for 5 minutes and enjoy warm.
