Making these Marshmallow Fluff Rice Krispie Treats is wonderfully simple, thanks to a handful of easy-to-find ingredients. Each one plays a crucial role in creating the unique layers of flavor and texture that make this dessert irresistible.

Butter (1/2 cup / 1 stick): Adds rich, creamy flavor and helps melt the marshmallows evenly without burning.
Mini marshmallows (16 oz): The star of the show, these melt into a luscious, gooey base that holds everything together.
Rice Krispie cereal (6 ½ cups): Provides that classic crispy crunch that gives the treat its iconic texture.
Marshmallow fluff (6 tablespoons): Adds extra fluffiness and sweetness, giving the treats a soft, cloud-like quality.
Peanut butter (8 tablespoons total, divided): Infuses a savory, nutty richness that balances the sweetness perfectly.
Pinch of sea salt: Enhances all the flavors and keeps the sweetness from feeling overly sugary.
Cooking spray: Keeps your tools and pan non-stick, making cleanup a breeze.

How to Make Marshmallow Fluff Rice Krispie Treats Recipe

Step 1: Melt Butter and Marshmallows

Begin by heating a large pot over low heat and adding your butter. Let it soften gently before adding the mini marshmallows. Stir slowly and patiently until everything melts into a smooth, glossy, gooey mixture. This warm, sticky base is what gives the treats their signature chewiness.

Step 2: Fold in Rice Krispie Cereal and Salt

Once melted, turn off the heat and sprinkle in the Rice Krispie cereal along with that pinch of sea salt. Use a gentle folding motion to combine—this keeps the cereal crunchy and ensures even distribution without crushing the delicate puffed rice.

Step 3: Add Peanut Butter and Marshmallow Fluff Swirls

Spray a spoon with cooking spray to prevent sticking, then dollop six tablespoons of peanut butter and six tablespoons of marshmallow fluff over the cereal mixture. Fold in just enough (about 4-5 large strokes) to create visible swirls. These swirls bring bursts of creamy nutty and sweet marshmallow flavor in every bite, making the texture even more exciting.

Step 4: Press Mixture Into Prepared Pan

Line a 9×13-inch pan with parchment paper and grease it lightly. Transfer your mixture to the pan and use a rubber spatula to spread it evenly but gently. You want the treats thick and satisfying without compacting them too much.

Step 5: Drizzle Remaining Peanut Butter and Cool

Finish things off by melting the remaining two tablespoons of peanut butter and drizzling it generously atop the treats. This little extra touch amps up the peanut flavor and adds a shiny, inviting look. Let the pan cool at room temperature for about an hour, or speed up the process by placing it in the fridge or freezer before slicing into 16 squares.

Garnishes

Simple garnishes like a light sprinkle of sea salt or mini chocolate chips can elevate these treats without overpowering their classic charm. For a festive touch, consider colorful sprinkles or a drizzle of melted dark chocolate to contrast the sweetness perfectly.

Side Dishes

These treats shine as a standalone snack but pair beautifully with cold milk or a creamy hot chocolate. For party platters, they join nicely alongside fresh fruit or a tangy yogurt dip which helps balance the indulgence.

Creative Ways to Present

Transform the presentation by layering these fluff-filled bites in a clear glass trifle bowl with alternating layers of whipped cream and fresh berries. Or use festive cookie cutters to create fun shapes that add excitement for kids and adults alike at parties.

Make Ahead and Storage

Storing Leftovers

Once cooled, wrap your Marshmallow Fluff Rice Krispie Treats tightly in plastic wrap or place them in an airtight container. Stored at room temperature, they stay fresh and chewy for up to one week, making them a great grab-and-go dessert.

Freezing

To keep treats longer, freeze them wrapped individually or as a block in heavy-duty freezer bags for up to three months. This way, you can thaw them quickly whenever a craving strikes without losing their wonderful texture.

Reheating

If you prefer your treats a little softer, gently warm them in the microwave for about 10-15 seconds. Be careful not to overheat, as the rice cereal can become soggy or the marshmallow too sticky to handle.

FAQs

Can I use regular marshmallows instead of mini marshmallows?

Absolutely! Regular marshmallows will work just fine; you might want to chop them into smaller pieces to help them melt evenly and smoothly for the best consistency in your Marshmallow Fluff Rice Krispie Treats Recipe.

Is it possible to make these treats nut-free?

Yes! Simply skip the peanut butter or replace it with a nut-free butter alternative like sunflower seed butter to maintain the creamy texture without any nut allergens.

Can I use a different cereal instead of Rice Krispies?

While Rice Krispies are classic for texture and taste, you can experiment with other puffed cereals like corn puffs or even crispy oats. Just keep in mind that the flavor and crunch will vary slightly.

How do I get the perfect chewy texture?

Low heat and gentle stirring during melting are key to keeping your marshmallows smooth and not burnt. Also, folding the cereal gently ensures the treats stay light and chewy rather than dense.

Will the treats stick to my hands when eating?

They can be a bit sticky! Loosening them with a little powdered sugar dust or lightly greasing your fingers can make snacking less messy and more enjoyable.

Instructions

Heat Butter and Marshmallows: Place a large pot over low heat and add the butter. Allow it to soften and start melting. Once the butter begins to melt, pour in the mini marshmallows and stir occasionally, letting them melt into a gooey, smooth mixture.
Mix with Rice Krispies and Salt: Turn off the heat. Add the Rice Krispie cereal along with a pinch of sea salt to the melted marshmallow and butter mixture. Fold gently using a spatula to coat the cereal evenly without crushing it.
Add Peanut Butter and Marshmallow Fluff: Spray a spoon with cooking spray. Use it to dollop 6 tablespoons of peanut butter and 6 tablespoons of marshmallow fluff on top of the mixture. Fold the cereal carefully in 4-5 large strokes to create thick swirls of peanut butter and marshmallow fluff rather than fully mixing them in.
Transfer to Pan: Prepare a 9×13 inch pan by greasing it and lining it with parchment paper. Transfer the mixture into the pan and use a rubber spatula to spread it out evenly.
Add Peanut Butter Drizzle: Melt the remaining 2 tablespoons of peanut butter and drizzle it over the top of the Rice Krispie mixture in the pan.
Cool and Serve: Allow the treats to cool at room temperature for about an hour or refrigerate/freezer to speed up the process. Once firm, cut into 16 squares and enjoy!

Notes

Once cooled, wrap the treats individually in plastic wrap or store them in an airtight container to keep fresh for up to one week.
You can freeze the treats for up to 3 months; thaw at room temperature before serving.
For easier mixing, spraying the spoon with cooking spray helps prevent sticking when folding in the peanut butter and marshmallow fluff.
