01 - Preheat your oven to 400°F.
02 - Place the chocolate chips and butter in a 10-inch oven-safe skillet. Place the skillet in the oven for 3–4 minutes, until the chocolate is mostly melted. Remove from oven and gently stir to combine.
03 - Arrange the Peeps marshmallows in a single layer over the melted chocolate, covering the surface completely.
04 - Return the skillet to the oven and bake for 4–6 minutes, until the Peeps are puffed and lightly golden. Watch closely to prevent burning.
05 - Remove from the oven and let cool for 2–3 minutes. Serve immediately with graham cracker pieces for dipping, scooping up molten chocolate and gooey Peeps with each bite.
