Why I Recommend Baking in a Cast Iron Skillet
- A 12-inch cast iron skillet is ideal for this recipe: it heats evenly and browns the marshmallows beautifully.
- The skillet makes it easy to toast and mix the marshmallows right in the pan, reducing extra dishes.
- Well-seasoned cast iron has a naturally non-stick surface that simplifies cleanup.
Ingredients
- Butter – 1/4 cup unsalted butter, softened
- Marshmallows – one 10 ounce bag of soft marshmallows
- Rice Krispies Cereal – 6 cups

How to Make Toasted Marshmallow Rice Krispies in a Skillet
- Preheat and toast – Preheat the oven to 400ºF. Place 1/4 cup unsalted butter in the bottom of a 12-inch cast iron skillet. Top with the marshmallows and bake 5–7 minutes, until the marshmallows are puffed and browned and the butter is melted. Watch closely so they don’t burn.
- Mix in the cereal – Remove the skillet from the oven and stir the melted marshmallows and butter together. Add 6 cups Rice Krispies cereal and fold until the cereal is evenly coated with the marshmallow mixture.
- Press and serve – Press the mixture evenly into the skillet, allow to cool slightly, slice into squares, and serve.
