Fluffer Nutter Muddy Buddies Ingredients

Here are the basics. Full amounts are listed in the printable recipe card at the bottom of the post.
- Butter
- Peanut butter
- Marshmallow cream — also known as marshmallow fluff
- Semi sweet chocolate chips
- Vanilla extract — adds flavor
- Rice Chex cereal
- Powdered sugar
- Mini marshmallows
How to Make Fluffernutter Puppy Chow
First, melt the butter and chocolate chips in a large bowl in the microwave in 30-second increments. Stir after each interval until melted. Then, add the vanilla and marshmallow cream into the chocolate mixture, and mix in the cereal. Use a gallon freezer bag to coat the cereal mixture and the marshmallows in powdered sugar.




Muddy Buddy Tips
Always melt chocolate in short intervals, and gently stir in between intervals until it melts. Otherwise, it will seize.
Add some of the powdered sugar to the bottom of the bag and the top so it’s easier to coat the cereal mixture when you shake it.
Store muddy buddies in an airtight container at room temperature for 1 week. You can freeze puppy chow for up to 3 months.

Variations
If you want a sweeter version, you can leave out the chocolate and use only peanut butter and marshmallow fluff.
You can use Corn Chex instead of Rice Chex.
Try adding mini peanut butter chips or mini peanut butter cups to the cereal mixture. You can also throw in some Reese’s pieces.
