Preheat oven to 425°F. Place oven-safe pan or skillet in oven while it preheats, until skillet is hot.

Sprinkle chocolate chips evenly in skillet, covering the entire surface. Top evenly with marshmallows, making sure distribution is even and snug.

Bake for 5 to 7 minutes, or until marshmallows are golden brown. Watch carefully to avoid burning.

Serve with graham crackers for dipping.
