Peanut Marshmallow Chocolate Clusters

The kitchen counter was chaos Christmas Eve three years ago when my sister announced we needed something sweet for the neighbor gifts. I grabbed whatever was in the pantry peanuts, marshmallows from hot cocoa prep, and a half-empty bag of chocolate chips. These clusters were born in twenty minutes of pure desperation.

My dad popped one into his mouth mid-wrapping paper frenzy and froze. He made me hide the container so they would actually make it to the neighbors porch. Now they are requested months in advance.

Ingredients

• Salted roasted peanuts: The salted ones are non-negotiable here, they balance the sweetness perfectly
• Mini marshmallows: The small ones distribute better throughout the chocolate than regular sized ones
• Semi-sweet chocolate chips: I have tried fancier chocolate but the classic chips melt most reliably
• Butterscotch chips: Completely optional but they add this warm caramel note people cannot quite identify
• Unsalted butter: Just one tablespoon makes the chocolate set up with a nicer snap

Instructions

Melt your base:

Combine the chocolate chips, butterscotch if using, and butter in a large microwave-safe bowl. Heat in thirty second bursts, stirring between each until smooth and glossy like pudding.

Let it cool slightly:

Wait about three minutes so the chocolate is not piping hot, otherwise your marshmallows will melt into oblivion instead of staying fluffy.

Combine everything:

Dump in the peanuts and marshmallows, then fold gently until every piece is coated in chocolate. The mixture should look gloriously messy.

Scoop the clusters:

Drop tablespoon-sized mounds onto your prepared baking sheets, leaving about an inch between them. Do not worry about perfection, the rustic look is part of the charm.

Set them up:

Let them sit at room temperature for two hours or pop them in the fridge for thirty minutes until they are firm to the touch.

Last summer I made a batch for a birthday party and the birthday girl kept sneaking them from the platter every time she thought no one was looking. That is when I knew these were not just holiday treats anymore.

Making Them Your Own

The beauty of this recipe is how forgiving it is. I have swapped the peanuts for pretzel pieces when feeding a crowd with allergies, and the crunch from the salted pretzels might be even better than the original version.

Pantry Swaps

Cashews or almonds work wonderfully here, though I always give them a rough chop first. White chocolate drizzled over the top before they set makes them look fancier for gift giving.

Serving And Storage

These clusters keep for a week at room temperature in an airtight container, though they have never survived more than three days in my house. Layer them between wax paper if you stack them.

• Package them in clear bags with pretty ribbon for instant gifts
• Set them out on a wooden board for parties
• Keep a hidden stash for yourself, seriously

Simple, sweet, and impossible to stop eating. These clusters have become my go-to for everything from last-minute gifts to late-night cravings.

Recipe FAQ

→ How long do peanut marshmallow clusters take to set?

The clusters will set at room temperature in about 2 hours. If you're in a hurry, refrigerate them for 30–40 minutes until firm. Room temperature setting is preferred for the best texture, as refrigeration can sometimes cause the chocolate to develop a slight bloom (white streaks) though this doesn't affect taste.

→ Can I use different types of chocolate?

Absolutely! While semi-sweet chocolate chips provide a classic balance, you can use milk chocolate for a sweeter treat, dark chocolate for a more sophisticated flavor profile, or even white chocolate for a completely different taste. Just keep in mind that white chocolate may set slightly softer than semi-sweet or dark varieties.

→ How should I store these clusters?

Store the clusters in an airtight container at room temperature for up to 1 week. Keep them away from direct sunlight and heat sources, which can cause the chocolate to melt or become soft. If your kitchen is particularly warm (above 75°F), you may prefer to refrigerate them, but bring to room temperature before serving for the best texture.

→ Can I make these nut-free?

Yes! Replace the salted roasted peanuts with an equal amount of pretzel pieces, salted pumpkin seeds, or even crushed graham crackers for a nut-free version. The pretzel option maintains that satisfying salty crunch that pairs so well with the sweet marshmallows and chocolate coating.

→ Why add butterscotch chips to the chocolate?

Butterscotch chips add a wonderful depth of flavor with their brown sugar and butter notes. They complement the peanuts beautifully and create a more complex, caramel-like flavor profile. If you prefer a purer chocolate taste, simply omit them and increase the chocolate chips to 2 cups total.

→ What's the best way to scoop the clusters?

A small cookie scoop (about 1 tablespoon) works perfectly for uniform, round clusters. If you don't have a scoop, use two tablespoons—one to scoop the mixture and one to scrape it onto the baking sheet. For larger clusters, use a 2-tablespoon scoop, which will yield about 12 pieces instead of 24.
