Ingredient Notes

• Marshmallow Fluff (7–8 oz jar): Provides sweetness and gooey texture. Substitute with mini marshmallows melted in a saucepan if unavailable.

• Creamy Peanut Butter (1 cup): Adds richness and flavor; natural peanut butter works but may make the mixture slightly less sticky.

• Rice Krispies Cereal (6 cups): The classic crunch. You can swap with Cocoa Krispies or another puffed rice cereal for variation.

• Butter (1/4 cup, 1/2 stick): Helps melt the peanut butter and marshmallow smoothly. Can be replaced with coconut oil for a dairy-free option.

• Vanilla Extract (1 tsp, optional): Enhances flavor without overpowering the peanut butter or marshmallow.

• Pinch of Salt: Balances sweetness and brings out peanut butter flavor.

Equipment Tips:

• Large saucepan for melting ingredients

• Spatula or wooden spoon for mixing

• 9×13-inch pan lined with parchment for easy removal and cleanup

How To Make Fluffernutter Rice Krispie Treats

1. Prepare Your Pan: Line a 9×13-inch baking dish with parchment paper and lightly grease it with butter. This prevents sticking and makes removal simple.

2. Melt Butter and Peanut Butter: In a large saucepan over low heat, melt 1/4 cup butter and 1 cup peanut butter, stirring constantly until smooth and fully combined.

3. Add Marshmallow Fluff: Reduce heat to low and stir in 7–8 ounces of marshmallow fluff until the mixture is smooth and glossy. (Tip: Stir gently to avoid burning.)

4. Add Vanilla and Salt: Stir in 1 tsp vanilla extract and a pinch of salt. This small step makes a big difference in flavor depth.

5. Fold in Rice Krispies: Remove the pan from heat and gradually fold in 6 cups Rice Krispies cereal until each piece is evenly coated. Use a spatula to avoid crushing the cereal.

6. Press into Pan: Transfer the mixture into the prepared pan. Use a lightly buttered spatula or wax paper to press it evenly into the pan without compacting too much.

7. Cool and Slice: Let the treats sit at room temperature for 30–40 minutes to firm up. Once set, lift from the pan and cut into squares or rectangles.

Tips for Success:

• Don’t overmix once the cereal is added—it will become tough.

• Press lightly; too firm can make the treats hard.

• For extra flair, drizzle melted chocolate on top or sprinkle with mini chocolate chips.

Storage Options

• Room Temperature: Store in an airtight container for up to 5 days. Keeps the texture soft and chewy.

• Refrigeration: Keep in a sealed container for up to 1 week. Let come to room temperature before serving for the best texture.

• Freezing: Wrap individually in plastic wrap and freeze for up to 3 months. Thaw at room temperature before eating.

• Reheating: Microwave for 10–15 seconds to soften slightly, but avoid overheating or they will become gooey.

Variations and Substitutions

• Chocolate Lovers: Add mini chocolate chips or drizzle melted chocolate on top before it sets.

• Nut-Free Version: Substitute sunflower seed butter for peanut butter for allergy-friendly treats.

• Cereal Swap: Try Cocoa Krispies, Fruity Pebbles, or Cheerios for fun variations.

• Seasonal Flavors: Add pumpkin spice in fall or peppermint extract in winter.

• Extra Crunch: Toss in chopped peanuts, pretzels, or cereal clusters for added texture.
