Peanut marshmallow clusters are my go to fix for those days when you want something sweet, but you do not want to turn on the oven, wash five bowls, and wait an hour to eat. I started making these after one too many late night pantry raids where I ended up mixing random snacks in a mug and calling it dessert. These clusters are basically that idea, but better, cuter, and actually shareable. They are chewy, crunchy, and a little messy in the best way, like a candy shop treat you made at home. If you have peanuts and marshmallows hanging around, you are already halfway there.

How To Make Rocky Road Peanut Clusters
If you like anything rocky road, this version is going to make you happy. You get chocolate, peanuts, and marshmallows all packed into little bite size piles. I like making them when friends are coming over because they look like you fussed, even though you really did not.
Ingredients you will need
- Chocolate: semi sweet chips or chopped chocolate bars
- Peanuts: salted is my favorite for the sweet and salty thing
- Mini marshmallows: they mix in easier than big ones
- Optional add ins: a spoon of peanut butter, a pinch of flaky salt, or a handful of crushed pretzels
I keep it simple most of the time, but if you love peanut butter desserts like I do, you can totally stir a spoonful into the melted chocolate. It makes the clusters a little softer and gives them that cozy peanut flavor. If you are in a peanut butter mood, you might also like these chocolate peanut butter peanut clusters because they hit a very similar craving.
Directions (my no stress method)
1) Line a baking sheet with parchment paper. Do not skip this unless you enjoy chipping chocolate off a pan later.
2) Melt your chocolate in a microwave safe bowl in short bursts, stirring each time. Stop when it is smooth and glossy.
3) Let the chocolate sit for a minute so it is not screaming hot. Then stir in peanuts and mini marshmallows.
4) Scoop little mounds onto the parchment using a spoon. I aim for about a heaping tablespoon each.
5) Let them set at room temperature, or pop the tray in the fridge for about 20 to 30 minutes.
One small tip that makes a big difference: if your marshmallows start looking melty or stringy, your chocolate is too hot. Just wait a minute next time before mixing. Also, if you want a slightly chunkier candy vibe, add a few peanuts on top of each mound right after scooping. It makes them look extra nice with zero extra effort.
“I brought these to a school bake sale and they were gone before the brownies. People kept asking if they were from a candy store. Nope, just my kitchen and a big bag of marshmallows.”
How to make No Bake Peanut Clusters
This is the version I make when I need something fast and I am not trying to be fancy. It is still the same basic idea, but you can tweak it depending on what you have. Think of it like a template. The main goal is a good chocolate base with crunchy peanuts, then you fold in marshmallows at the end so they stay fluffy.
Here is how I like to think about it when I am winging it:
Pick your base: milk chocolate for a sweeter bite, semi sweet for balance, or white chocolate if you want that super creamy candy taste.
Pick your crunch: peanuts are classic, but you can mix in almonds, cashews, or even a handful of cereal if that is what you have.
Pick your chewy: mini marshmallows are perfect, but chopped big marshmallows also work.
My favorite no bake trick is using a double bowl setup if you are nervous about burning chocolate. You just set a heat safe bowl over a pot of barely simmering water and stir the chocolate until it melts. It takes a little longer than the microwave, but it is pretty foolproof.
If you are the type who loves quick no bake stuff (same), you should check out these chocolate peanut butter no bake cookies. They have that same fast satisfaction and they disappear just as quickly.
Also, let us talk texture for a second. Peanut marshmallow clusters are best when the peanuts are salty and the chocolate is not overly sweet. If all you have is unsalted peanuts, add a tiny pinch of salt into the melted chocolate. It wakes the whole thing up.
How to store
Storing these is simple, but there are a couple things that keep them tasting fresher longer. Since peanut marshmallow clusters are basically candy, they hold up well, but marshmallows can get weird if you leave them open to air for too long.
Room temperature: Store in an airtight container for about 5 to 7 days. Keep them in a cool spot away from sunlight.
In the fridge: Great if your kitchen runs warm. They will be a little firmer and snappier. I like them this way when I want a clean bite.
In the freezer: Yes, you can freeze them. Place them in a freezer bag with parchment between layers. They will keep for about 2 months. Let them sit out for 10 minutes before eating so you do not crack a tooth.
One more thing: do not store them next to anything with a strong smell like chopped onions or garlic bread. Chocolate can pick up odors, and nobody wants onion scented dessert.
If you are building a little homemade candy stash, you might also love making chocolate covered peanut butter hearts for holidays or gifting. They store nicely too, and they feel extra special.
More Easy Candy Recipes To Try
Once you make a batch of clusters, it is hard not to go on a little homemade candy kick. I am not saying you will suddenly become the person who keeps chocolate in the pantry at all times, but I am also not saying you will not.
Here are a few easy ideas that match the same vibe:
Crunchy cups: chocolate with crispy cereal or rice cereal pressed into little liners. They are super snackable.
No bake bars: peanut butter and oats pressed into a pan, then sliced. Great when you want something you can grab from the fridge.
Marshmallow treats: anything that mixes melted chocolate with marshmallows tends to be a crowd pleaser.
If you want something that feels like a fun snack board item, these peanut butter pretzel bites are awesome. Sweet, salty, and easy to pop in your mouth while you pretend you are only having one.
And if you ever want to lean into the soft cookie side of peanut butter sweets, I have had my eye on these 4 ingredient cake mix peanut butter soft cookies because sometimes you want cookies without a whole project.

Peanut marshmallow clusters feel perfect for movie nights, road trips, bake sales, and those weeks where you need a little something sweet in the fridge.
Some ideas to keep on your list:
Layered no bake desserts: peanut butter and chocolate in a pan, chilled, and sliced. Very low effort, very high reward.

Basically, once you have chocolate and peanut butter in the house, you are never too far away from a good treat. And if you have marshmallows too, well, you are dangerously prepared.
Common Questions
Can I use big marshmallows instead of mini?
Yes. Just snip them into smaller pieces with kitchen scissors. Mini marshmallows mix in more evenly, but big ones still work.
Why did my marshmallows melt into the chocolate?
Your chocolate was too hot. Let it cool for a minute or two after melting, then stir in the marshmallows.
How do I keep the clusters from sticking together?
Use parchment between layers in your container. Also make sure they are fully set before stacking.
Can I make them without peanuts?
Totally. Swap in almonds, cashews, or even pretzel pieces. Just keep the same general ratio so the chocolate can coat everything.
Are these good for gifting?
Yes, especially in little treat bags. If you are gifting, I recommend keeping them cool so they do not get smudgy.
