Muddy Buddies Marshmallow Treats

Muddy Buddies and Rice Krispie treats got married and had the most deliciously irresistible baby ever! Chocolate and peanut butter with gooey marshmallow is the best mash up of all time!

I want to take credit a tiny bit but mostly I want to yell from the rooftops that my own daughter is a genius. A legit genius. Claire was helping me make chex muddy buddies puppy chow one day when she said, “Mom, I think we should try to make these into rice krispies treats.”

And then I dreamt of them, thought of them, salivated over the idea of them and flat out obsessed for almost 2 months before I just couldn’t take it anymore and had no choice but to make them. 
And they were glorious. 
I mean, hands down one of our new favorite family treat recipes. There’s no going back. 
Is it sweet? Yes, but the salty peanut butter and cereal, and additional salt breaks it up. I couldn’t stop eating these and I’m not usually a crazy sweet dessert person!

Most people have probably made muddy buddies, or puppy chow, as I called it growing up. Most people have probably made rice krispie treats. But have you every combined the two?? Here are the ingredients you will need:
Muddy Buddies
Rice Chex Cereal (Corn Chex or Wheat Chex also work)
Chocolate Chips
Peanut Butter

All the measurements for each ingredient can be found in the recipe card below.

How to Make Muddy Buddies Marshmallow Treats
If you want the quick and simple directions for making these babies, you will make a batch of muddy buddies. Let them cool and set, and then make them all stick together with melted butter and marshmallows. You’re welcome, I just changed your life.
Here are a little more detailed instructions which can also be found in the recipe card at the end of the post:
Muddy Buddies
Melt the peanut butter, butter and chocolate chips together over medium heat on the stove or in the microwave.
Gradually combine the cereal and pb/choc mixtures and stir until evenly coated.
Let it cool slightly and then add the powdered sugar little by little and stir to combine.

Marshmallow Treats
Prepare a 9×13 baking dish with cooking spray and foil or parchment.
Melt the butter, salt and some of the marshmallows on the stove over medium heat or in the microwave. Heat it until everything is melted and smooth.
Add the vanilla and stir it all together again.
Pour over the muddy buddies and mix everything together well.
Add the rest of the marshmallows and press the mixture into your prepared pan.
Let them cool for a while and cut and serve.
These directions can be found in full detail in the recipe card at the end of this post.

The Best Way to Eat Muddy Buddies?
Mix everything together and eat while warm. My goodness, you will thank me later!! Don’t eat them all though! Save enough to make these marshmallow treats!
How to Store Marshmallow Treats
If I’m just making muddy buddies, I like to keep them in the refrigerator, but in a marshmallow bar form, it’s all about room temperature. They stay gooey and delicious. Store with plastic wrap over the top or with a lid on your dish if you have one.
How Long Will Muddy Buddies Marshmallow Treats Last?
These bars will keep at room temperature for up to 3 days, but they have never lasted past day 2 at our house!

Best of luck buttoning up your jeans but don’t you dare feel bad about it. Dessert is ok!!! It’s ok to just enjoy a meal and treats one night. The next day just go back to healthy eating and leave the sugar for the weekend only. Mmmmmmm, these muddy buddies marshmallow treats are my new obsession!
