These no-bake clusters combine the satisfying crunch of salted roasted peanuts with soft, fluffy mini marshmallows, all enveloped in a rich blend of semi-sweet chocolate and butterscotch. The contrast between salty peanuts and sweet coating creates an addictive flavor profile that's impossible to resist.

Ready in under 30 minutes with just 5 ingredients, these treats are perfect for last-minute gifting, holiday platters, or whenever a sweet craving strikes. The mixture sets beautifully at room temperature or can be hurried along in the refrigerator.

Customize easily by swapping peanuts for cashews, almonds, or even pretzel pieces for a nut-free version. A sprinkle of sea salt or white chocolate drizzle adds a professional finishing touch.

My youngest once asked if we could just dump everything sweet in the pantry into one bowl, and surprisingly, the result was these clusters that disappeared before they even fully set.

I made a double batch for a neighborhood potluck and three different neighbors asked for the recipe while still standing in my kitchen holding the empty serving plate.

Ingredients

  • 2 cups salted roasted peanuts: The salt balances the sweetness perfectly, so dont use unsalted or the result tastes flat
  • 2 cups mini marshmallows: Mini ones distribute better than regular sized, and fresh marshmallows make fluffier clusters
  • 1 1/2 cups semi-sweet chocolate chips: Semi-sweet gives the best balance, but milk chocolate works if you prefer sweeter results
  • 1/2 cup butterscotch chips: These add a subtle caramel note that makes people ask what the secret ingredient is
  • 1 tablespoon unsalted butter: Keep the butter unsalted since the peanuts already provide enough saltiness

Instructions

Melt the chocolate base:
Combine chocolate chips, butterscotch chips, and butter in a large microwave safe bowl. Heat in thirty second intervals, stirring thoroughly after each, until the mixture is completely smooth and glossy
Let it cool slightly:
Wait two or three minutes so the chocolate isnt too hot, otherwise the marshmallows will melt away instead of staying fluffy
Coat everything evenly:
Pour in peanuts and marshmallows, then fold gently until every piece gets coated but you can still see distinct marshmallows
Drop and set:
Scoop tablespoons onto prepared baking sheets, leaving an inch between each mound. Let them firm up at room temperature for two hours or chill for thirty minutes

My mom started keeping a batch in the freezer for surprise guests, and now I understand why they became her go to emergency treat.

Making Them Your Way

The beauty of this recipe is how easily it adapts. Swap peanuts for cashews or almonds, or use pretzels instead for a nut free version that still has that perfect crunch.

Common Chocolate Mistakes

Overheating chocolate makes it seize and turn grainy. Microwave in short bursts and stir between every one, even when the chocolate still holds its shape.

Storage Secrets

These keep surprisingly well for a treat with marshmallows. Store them in an airtight container with parchment paper between layers, and they stay perfect for a whole week.

  • Add a sprinkle of flaky sea salt right before they set for an elevated look
  • Drizzle melted white chocolate over cooled clusters for gifting occasions
  • Work quickly once you add the mix-ins or the chocolate starts thickening

Something magical happens when salty peanuts, fluffy marshmallows, and melted chocolate come together in one bowl.

Recipe FAQs

Stored in an airtight container at room temperature, these clusters will maintain their texture and flavor for up to one week. Avoid refrigeration unless necessary, as condensation can make the chocolate cloudy and the marshmallows slightly sticky.

Absolutely! While semi-sweet chocolate provides the classic flavor balance, you can substitute with milk chocolate for a sweeter result, dark chocolate for intense richness, or white chocolate for a completely different profile. Just adjust the sweetness accordingly.

Melting in 30-second intervals with stirring between each burst prevents overheating. The addition of butter helps create a smooth, pourable consistency. If your chocolate does seize, try whisking in a teaspoon of vegetable oil to bring it back to liquid form.

Yes! Replace the salted peanuts with pretzel pieces, salted sunflower seeds, or pumpkin seeds for that same salty crunch. The result will be just as delicious and safe for those with nut allergies or attending nut-free schools and events.

Allowing the chocolate to cool for 2-3 minutes prevents the marshmallows from melting too quickly and losing their fluffy texture. You want the coating warm enough to coat everything evenly, but not so hot that it dissolves the marshmallows completely.

Sprinkle with flaky sea salt before setting for a gourmet finish, drizzle with contrasting white chocolate, or roll the edges in colorful sprinkles, crushed candy canes, or chopped nuts while the chocolate is still soft. Perfect for holidays and special occasions.
