Fluffernutter Muddy Buddies
I was absolutely obsessed with Muddy Buddies growing up, but this version takes it to the next level. They’ve got all the nostalgic flavors I loved as a kid, with a fluffernutter twist thanks to peanut butter and marshmallow fluff. Sweet, crunchy, and completely addictive—you’ll want to make a big batch because they disappear fast.
Servings cups
Ingredients
- 6 1/2 cups rice chex cereal
- 1 1/4 to 1 1/2 cups powdered sugar
COATING:
- 3/4 cup semi-sweet chocolate chips
- 1/2 cup peanut butter
- 1/4 cup unsalted butter
- 1 teaspoon vanilla extract
- 1/3 cup marshmallow fluff
- pinch of salt
OPTIONAL MIX-INS:
- mini marshmallows
- mini peanut butter cups
- mini chocolate chips
- peanut butter chips
- reese’s Pieces
Instructions
- Add the chex cereal to a large mixing bowl and set aside.
- In a medium pot over low heat, add the chocolate chips, peanut butter, butter, marshmallow fluff, vanilla extract, and salt. Stir continuously with a rubber spatula until smooth and fully melted, about 5–7 minutes.
- Pour the mixture over the Rice Chex and very gently fold with the rubber spatula until all the cereal is evenly coated.
- Allow the coated cereal to cool for about 4 to 5 minutes so it’s no longer piping hot, but not fully hardened.
- Transfer to a large zip-top bag or container, add the powdered sugar (adding as much or as little as you like), seal, and shake until the cereal is well coated.
- Optional: Spread onto a baking sheet to finish cooling and setting. This isn’t necessary, but it can help the mix stay extra crispy.
- Once cooled, mix in any of the optional add-ins like mini marshmallows, peanut butter cups, or Reese’s Pieces or just leave as is like the original!
- Store in an airtight container or ziploc back at room temperature for up to 1 week.
Notes
Q: Can I use a different cereal besides Rice Chex?
A: Yes! Corn Chex or even Crispix will work if that’s what you have on hand. For a slightly different texture, Crispix adds a little more crunch. Q: Do I have to use marshmallow fluff?
A: The fluff gives this a fluffernutter twist, but if you want a more classic Muddy Buddies flavor, you can leave it out. Leaving it out makes it more like traditional Muddy Buddies—still delicious! Q: How do I keep them from getting soggy?
A: Make sure to let the coated cereal cool for a few minutes before adding the powdered sugar, and spread them out on a baking sheet to set if you want them extra crispy. Using a baking sheet is optional, but it helps keep them crisp. Q: How do I make them less sweet?
A: You can reduce the powdered sugar slightly, or use a little less peanut butter in the coating. Start by cutting the powdered sugar to the lower end of the range and taste as you go. Q: Other flavor combos to try?
A: You can switch up the coating entirely! Try white chocolate with matcha, cookies and cream with crushed cookies, or dark chocolate with a sprinkle of sea salt. Peanut butter + milk chocolate is a classic, or even mix in caramel or butterscotch chips for a twist. Q: Can I make these ahead of time?
A: Definitely! They stay fresh in an airtight container at room temperature for up to a week. Just give them a gentle shake before serving if they’ve been sitting a while.
