Set oven broiler to high.

Divide the chocolate chips evenly between two miniature cast iron skillets (or in one large cast iron skillet). Drop the peanut butter in dollops over the skillets and sprinkle the chopped peanuts evenly over both. Top with a layer of mini marshmallows.

Set skillets in the oven and broil until the marshmallows are puffed and golden brown. If the chocolate chips haven’t completely melted, turn the oven to 350 degrees and bake for 5 to 10 minutes longer. Serve with graham crackers for dipping.
