How to Make It
Preheat oven to 450°F. Heat an oven safe skillet (preferably cast iron) on medium-high. Add butter and swirl to coat. Remove skillet from heat and add Nutella to form an even layer. Add chocolate chips. Layer with marshmallows until the mixture is completely covered. Bake at 450°F for 4-5 minutes, or until marshmallows are golden brown. Serve with graham crackers.
