    Ingredients Needed

    Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.

    • Marshmallows: Use mini marshmallows, not the large ones.
    • Rice Cereal: Feel free to use either the name brand of Rice Krispies or a generic brand. The only difference I have found is the generic brand doesn't stay as crunchy long, but the flavor is exactly the same.
    • Graham Crackers: I used honey graham crackers, but you could also use the chocolate ones.
    • Chocolate: I used semi-sweet chocolate chunks.
    Ingredients needed: rice cereal, mini marchmallows, salt, chocolate chunks, butter, vanilla extract, and graham crackers

    Instructions

    Here are the step by step instructions on how to make these rice krispie s'mores.

    Step 1: Melt the butter. In a large saucepan over medium-low heat, melt the butter. Once melted, add 5 cups of the marshmallows and stir occasionally until completely melted.

    Step 2: Add the cereal. Remove the pan from the heat and mix in the vanilla extract and salt. Then gently mix in the cereal and graham cracker pieces until evenly coated.

    Step 3: Add the remaining ingredients. Gently mix in the chocolate chunks and the remaining marshmallows.

    Step 4: Press into baking pan. Spoon the mixture into the prepared pan and use a piece of parchment paper that's been sprayed with cooking spray to press it down into an even layer.

    Tip! Add extra chocolate and marshmallows to the top of the bars and press down gently.

    Step 5: Cool and serve. Allow the bars to cool for 20 minutes before slicing them into bars and serving.

    Storage Tips

    Although they're best consumed within 1-2 days, they will last up to 3 days in an airtight container at room temperature.

    Expert Baking Tips

    • Baking Pan: Line your 8x8-inch baking pan with parchment paper and then non-stick spray.
    • Chocolate: I used chocolate chunks but you could also use chocolate chips or a chocolate bar broken up into pieces (such as Hershey's bars).
    • Parchment Paper: Use a piece of parchment paper lightly sprayed with non-stick spray to evenly press down the rice krispies into the prepared baking dish.

    Recipe FAQs

    Can I Make These With A Different Cereal?

    Although I haven't tried, you could probably swap out the rice krispie cereal with either golden grahams cereal or even cocoa krispies.

    Can I Make These Ahead Of Time?

    You certainly can, but just note that they might not be as crunchy the next day.

    Can I Use Marshmallow Creme?

    I have never tried this before. If you do, let me know how it turned out for you!
