01 - Preheat the oven to 375°F. Ensure the oven-safe skillet or baking dish is clean and dry.
02 - In a microwave-safe bowl, combine chocolate chips and heavy cream. Microwave in 30-second intervals, stirring after each, until mixture is smooth and fully melted.
03 - Spread peanut butter evenly across the bottom of an 8-inch oven-safe skillet or baking dish. Pour the melted chocolate mixture over the peanut butter and smooth the surface with a spatula.
04 - Distribute mini marshmallows evenly over the chocolate layer.
05 - Bake for 8 to 10 minutes, or until the marshmallows are puffed and golden brown.
06 - Remove the baking dish from the oven. Sprinkle crushed graham crackers evenly over the toasted marshmallows.
07 - Allow the dip to cool for 5 minutes before serving. Offer extra graham crackers, pretzels, or apple slices on the side for dipping as desired.
