The middle layer is made up of many small white marshmallows, covering most of the peanuts partially. On top there is a drizzle of thick, smooth caramel sauce with a glossy orange shade, some of which is sitting on the marshmallows. A metal spoon is inserted into the mixture on the left side of the bowl. The bowl rests on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

I love that the ingredients for this recipe are straightforward yet essential, each playing a key role in making these clusters absolutely scrumptious. The chocolate creates a luscious coating, the marshmallows add lightness, and the peanuts bring that satisfying crunch and saltiness.

2 cups semi-sweet chocolate chips: Adds a rich, slightly bitter chocolate flavor that balances sweetness.
2 cups milk chocolate chips: Provides creamy smoothness and sweetness for the perfect chocolate blend.
3 tablespoons vegetable oil: Helps melt the chocolate evenly and gives the clusters a glossy finish.
2 cups miniature marshmallows: Light and fluffy, they add a chewy contrast that makes the clusters fun to eat.
1½ cups dry roasted cocktail peanuts: Offers a salty, crunchy texture to perfectly complement the chocolate and marshmallows.

Directions

Step 1: Line two baking sheets with wax paper and set them aside. This will make it super easy to remove the clusters once they’re set.

Step 2: Combine the semi-sweet and milk chocolate chips with the vegetable oil in a large heat-safe mixing bowl. Microwave the mixture in 30-second intervals, stirring after each until the chocolate is fully melted and smooth. This gentle heating prevents the chocolate from burning and ensures a silky texture.

Step 3: Allow the melted chocolate to cool down to lukewarm before stirring in the miniature marshmallows and dry roasted peanuts. Make sure every marshmallow and nut is completely coated with chocolate for maximum flavor in every bite.

Step 4: Using a 1½ tablespoon cookie scoop, drop the candy clusters onto the prepared baking sheets, spacing them about 2 inches apart so they don’t stick together as they set.

Step 5: Place the baking sheets in the refrigerator and chill the clusters until the chocolate is completely set and firm, usually about 30 minutes or until ready to serve.

Servings and Timing

This recipe yields approximately 30 peanut marshmallow clusters, which makes it great for sharing or for having a tasty stash throughout the week. The prep time is incredibly short—about 10 minutes to melt and mix everything. The main waiting game comes from chilling the clusters, which takes roughly 30 minutes. Altogether, the total time from start to finish is about 40 minutes, making it a quick yet satisfying treat to whip up any day you want something sweet and crunchy.

I enjoy serving these clusters at room temperature, which really lets the chewy marshmallows and crunchy peanuts shine without the chocolate being too hard. They’re perfect alongside a cup of coffee or tea for a cozy afternoon pick-me-up. For a festive touch, I sometimes arrange them on a decorative platter garnished with a sprinkle of edible gold dust or a few whole peanuts around the edges.

For parties, I love plating these clusters in small paper cupcake liners—they’re so easy for guests to grab and go, plus it keeps the serving clean. If you want to accompany them with drinks, they pair beautifully with a cold glass of milk or a smooth dessert wine like a rich port or tawny. Non-alcoholic sparkling cider is also a wonderful pairing, adding a light crispness against the sweet chocolate.

These clusters are absolutely versatile, whether it’s a casual family movie night, an elegant holiday gathering, or just an indulgent treat on a weeknight. Because they’re bite-sized, portion control feels easy but indulgence is guaranteed every single time.

Variations

One of the reasons I keep coming back to this Peanut Marshmallow Clusters Recipe is how flexible it is. For example, if you want to switch things up, try swapping out the dry roasted peanuts for pecans, cashews, or almonds to give a different nutty flavor and texture. I’ve found that smoked or honey-roasted nuts add a really fun twist as well.

If you’re catering to dietary needs, you can make this gluten-free with confidence since the ingredients are naturally free of gluten—just double-check the marshmallows for any cross-contamination. To make it vegan, I recommend substituting the chocolate chips and marshmallows with vegan-friendly versions which are surprisingly easy to find these days, plus using coconut oil instead of vegetable oil to keep it plant-based and rich.

For a flavor variation, sometimes I like to sprinkle a pinch of sea salt on top right before chilling the clusters to enhance the sweetness with a salty kick. Alternatively, stirring in a handful of dried cranberries or shredded coconut adds a chewy contrast that’s delightful. And while I usually chill them in the fridge, you can try letting them set at room temperature if your kitchen is cool enough, though it may take a bit longer.

Storage and Reheating

Storing Leftovers

I always store leftover Peanut Marshmallow Clusters in an airtight container to keep them fresh and crunchy. They stay delicious for up to two weeks at room temperature, but I personally prefer keeping them in the refrigerator if my kitchen is warm. Wax paper or parchment paper between layers prevents the clusters from sticking together and makes it easy to portion out later.

Freezing

These clusters freeze wonderfully if you want to make a big batch ahead of time. I like to place them on a baking sheet first to freeze individually, then transfer them to a zip-top freezer bag or airtight container. They’ll keep well for about 2 to 3 months frozen. Just thaw them in the fridge for a few hours before enjoying, and they taste almost as fresh as when first made.

Reheating

Since the clusters are best enjoyed cool or at room temperature, I generally avoid reheating them. However, if the chocolate feels too firm after chilling, letting the clusters sit out for 10 to 15 minutes softens them perfectly without losing texture. Microwaving is not recommended because it can cause the marshmallows to melt too much and the chocolate to seize or become grainy.

FAQs

Can I use only one type of chocolate chip instead of two?

Absolutely! Using either semi-sweet or milk chocolate chips alone still produces delicious clusters. Combining both adds a richer, more complex chocolate profile, but feel free to customize based on your preference or what you have on hand.

Do I need to use vegetable oil in the recipe?

The vegetable oil helps melt the chocolate smoothly and gives the clusters a shiny finish. If you prefer, you can substitute coconut oil or leave it out, but keep in mind the chocolate might be thicker and set with a different texture.

Can I substitute the peanuts with other nuts or seeds?

Definitely! Peanuts add a classic crunch and salty flavor, but almonds, pecans, cashews, or even pumpkin seeds work beautifully too. Just choose nuts or seeds that you enjoy and that suit any dietary needs.

How long do the Peanut Marshmallow Clusters keep at room temperature?

Stored in an airtight container, the clusters are best eaten within 1 to 2 weeks at room temperature. If your kitchen is warm, I recommend refrigerating them to prevent the chocolate from melting and to keep the texture fresh.

Is there a way to make these clusters without using a microwave?

Yes! You can melt the chocolate and vegetable oil using a double boiler on the stovetop. Stir continuously until smooth and fully melted, then proceed with the recipe as usual.
