What Kind of Chocolate Should I Use?

Semi-sweet chocolate chips are the go-to for these clusters. They balance perfectly with the sweetness of marshmallows and the saltiness of the peanuts. You can also mix in milk chocolate or dark chocolate depending on your taste. If you’re feeling extra fancy, a swirl of white chocolate can create a marbled effect and add another layer of flavor.

Ingredients for the Peanut Marshmallow Clusters

Semi-sweet chocolate chips – Melted chocolate gives these clusters their rich, smooth coating. Semi-sweet is a great balance of sweet and bold.

Butterscotch chips – Adds a buttery, deep caramel flavor that blends beautifully with the chocolate.

Mini marshmallows – The soft, chewy texture contrasts perfectly with the crunchy peanuts and hard chocolate shell.

Salted roasted peanuts – Bring the crunch and the salty kick. Salted is best to offset the sweetness from the other ingredients.

Butter – Helps smooth out the chocolate and butterscotch mixture for easier coating.

How To Make the Peanut Marshmallow Clusters

Step 1: Melt the Chips

In a large microwave-safe bowl, combine the semi-sweet chocolate chips and butterscotch chips. Add the butter on top. Microwave in 30-second intervals, stirring between each, until completely melted and smooth. Be careful not to overheat, or the mixture may seize.

Step 2: Add the Crunch and Chew

Gently stir in the roasted peanuts until fully coated in the chocolate mixture. Once the peanuts are evenly mixed, fold in the mini marshmallows. Mix just enough to combine, without over-stirring and melting the marshmallows.

Step 3: Drop and Set

Line a baking sheet with parchment paper. Use a spoon or small cookie scoop to drop clusters onto the paper. Make sure they’re spaced out slightly so they don’t stick together.

Step 4: Chill to Firm

Place the baking sheet in the refrigerator for about 30 minutes or until the clusters are fully set. Once hardened, they’re ready to eat!

How to Serve and Store Peanut Marshmallow Clusters

These clusters are best served chilled or at room temperature, depending on how firm you like the chocolate. They make adorable dessert tray additions, sweet gift bag fillers, or late-night bites straight from the fridge.

To store, keep them in an airtight container in the refrigerator for up to 2 weeks. If you’re stacking them, place parchment paper between layers to prevent sticking. You can also freeze them for longer storage—just let them thaw in the fridge for best texture.

Frequently Asked Questions

Can I use unsalted peanuts instead of salted?

Yes, but the salted peanuts add that delicious contrast to the sweet elements. If using unsalted, you can add a small pinch of flaky sea salt on top.

Can I make these nut-free?

Absolutely. Swap peanuts for pretzel pieces, sunflower seeds, or even crispy rice cereal to keep the crunch without nuts.

Can I use regular marshmallows?

Mini marshmallows work best for even distribution, but you can chop regular ones into smaller pieces if that’s what you have.

How long do these take to set?

About 30 minutes in the fridge. If your kitchen is cool, they may also set at room temperature in about 1 hour.

Can I microwave the mix all at once?

Yes—but always stir between intervals to avoid overheating. Stirring helps melt the chips evenly and prevents burning.

Are these gluten-free?

They can be! Just double-check your marshmallow and butterscotch chip brands to ensure they’re certified gluten-free.
