Fluffernutter Rice Krispie Treats Recipe
Introduction
Fluffernutter Rice Krispie Treats combine the nostalgic flavors of peanut butter and marshmallow fluff with the classic crunch of Rice Krispies cereal. These gooey, sweet bars are easy to make and perfect for a fun snack or dessert that everyone will love.

Ingredients
- 6 cups Rice Krispies cereal
- 6 tablespoons unsalted butter
- 6 cups mini marshmallows (divided)
- 1 cup creamy peanut butter
- Pinch salt (if your peanut butter doesn’t have any)
- 7.5 ounce container of Marshmallow Fluff
Instructions
- Step 1: Prep a 9×13 baking pan by lining it with parchment paper, allowing the edges to hang over the sides. Spray the parchment with nonstick spray and set aside.
- Step 2: Pour the Rice Krispies cereal into a large bowl and set aside.
- Step 3: In a medium saucepan, melt the butter over low heat. Add 4 cups of mini marshmallows and stir frequently until melted and mostly combined. It’s okay if it’s not fully smooth.
- Step 4: Remove the pan from heat and stir in the peanut butter until combined. If your peanut butter is unsalted, add a pinch of salt and mix well.
- Step 5: Immediately pour the peanut butter mixture into the bowl with Rice Krispies. Add the Marshmallow Fluff and the remaining 2 cups of mini marshmallows, then stir to coat and combine everything evenly.
- Step 6: Transfer the mixture to the prepared baking pan and press it into an even layer. You can use the bottom of another 9×13 pan, spray your hands with nonstick spray and press with your palms, or place parchment paper on top before pressing to avoid sticking.
- Step 7: Let the treats set for at least 15 minutes. Once firm, slice into 12 large bars. Serve and enjoy!
Tips & Variations
- Use crunchy peanut butter instead of creamy for added texture.
- For a nut-free version, substitute the peanut butter with sunflower seed butter and omit the salt.
- Press the mixture more firmly for denser bars or less for lighter treats.
- Wrap individual bars in wax paper for easy grab-and-go snacks.
Storage
Store the Fluffernutter Rice Krispie Treats in an airtight container at room temperature for up to 3 days. To keep them soft, avoid refrigerating. If needed, you can warm them gently in the microwave for a few seconds before serving.

FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, you can chop regular marshmallows into smaller pieces and use the same quantity. Mini marshmallows just melt more easily and evenly.
How do I prevent the treats from sticking to my hands when pressing?
Spray your hands lightly with nonstick spray or use parchment paper on top of the mixture when pressing it down. This helps avoid sticky fingers and makes shaping easier.

Ingredients
Main Ingredients
- 6 cups Rice Krispies cereal
- 6 tablespoons unsalted butter
- 6 cups mini marshmallows (divided)
- 1 cup creamy peanut butter
- Pinch salt (if your peanut butter doesn’t have any)
- 7.5 ounce container of Marshmallow Fluff
Instructions
- Prepare the Pan: Line a 9×13 inch baking pan with parchment paper, allowing the edges to hang over the sides for easy removal later. Spray the parchment with nonstick spray and set the pan aside.
- Set Up Cereal: Pour the Rice Krispies cereal into a large mixing bowl and set it aside for combining later.
- Melt Butter and Marshmallows: In a medium saucepan over low heat, melt the unsalted butter. Add 4 cups of the mini marshmallows and stir frequently until they melt and the mixture is mostly combined. It’s fine if the marshmallows aren’t fully incorporated, as this will help achieve the right texture.
- Add Peanut Butter and Salt: Remove the saucepan from the heat and stir in the creamy peanut butter. If your peanut butter is unsalted, add a pinch of salt now to enhance the flavors and stir to combine thoroughly.
- Mix with Cereal and Additional Ingredients: Immediately pour the peanut butter mixture over the Rice Krispies in the large bowl. Add the Marshmallow Fluff and the remaining 2 cups of mini marshmallows. Stir everything together until the cereal is evenly coated.
- Press into Pan: Transfer the mixture into the prepared baking pan and press down firmly to create an even layer. For an even surface, you can use the bottom of another 9×13 inch pan, spray your hands with nonstick spray and press with your palms, or place a piece of parchment paper on top and press down.
- Let Set and Serve: Allow the treats to set at room temperature for at least 15 minutes to firm up. Once set, lift the treats out using the parchment edges, slice into 12 large bars, and serve.
Notes
- Using unsalted butter and adding a pinch of salt can balance sweetness, especially if peanut butter is unsalted.
- Pressing the mixture evenly helps the bars set better and slice cleanly.
- Store treats in an airtight container at room temperature for up to 3 days for optimal freshness.
