Ingredients for Peanut Marshmallow Clusters Candy
- 2 cups semi-sweet chocolate chips
- 2 cups milk chocolate chips
- 3 tbsp vegetable oil
- 2 cups mini marshmallows
- 1½ cups dry roasted cocktail peanuts
Use fresh chocolate chips and peanuts for the best texture. The vegetable oil helps the melted chocolate stay smooth and easy to stir, while the marshmallows should be added after the chocolate has cooled briefly so they keep their shape instead of melting into the mixture.
How to Make Peanut Marshmallow Clusters Candy
Step 1: Prepare the Pan
Line a large baking sheet with parchment paper or wax paper. Make sure the sheet fits in your refrigerator, and set it near your work area. Measure the mini marshmallows and peanuts before melting the chocolate so the mixture can be assembled without delay.
Step 2: Combine the Chocolate and Oil
Place the semi-sweet chocolate chips, milk chocolate chips, and vegetable oil in a large microwave-safe bowl. If using the microwave, heat the mixture at 50 percent power for 30 seconds, then stir well. Continue heating in 15- to 20-second intervals, stirring after each interval, until the chips are nearly melted. The residual heat will finish the job as you stir. You can also melt the mixture in a heatproof bowl set over a saucepan of barely simmering water, stirring often and keeping water away from the chocolate.
Step 3: Cool the Melted Chocolate
Stir until the chocolate is completely smooth, then let it stand for about 5 minutes. It should remain fluid but feel warm rather than hot. This short cooling period helps prevent the mini marshmallows from melting when they are stirred into the chocolate.
Step 4: Fold in the Peanuts and Marshmallows
Add the dry roasted cocktail peanuts and mini marshmallows to the bowl. Fold gently with a silicone spatula until everything is coated. Work carefully so the marshmallows stay intact and the peanuts remain distributed throughout the chocolate.
Step 5: Portion the Clusters
Drop the mixture onto the prepared baking sheet in 8 rounded portions, using a large spoon or a quarter-cup measure. If the mixture begins to firm up, gently stir it once or twice before portioning the remaining clusters. Leave a little space between each mound so the pieces do not join together.
Step 6: Chill and Store
Refrigerate the baking sheet for 30 to 45 minutes, or until the chocolate is firm. Transfer the clusters to an airtight container, separating layers with parchment paper if needed. Keep them refrigerated for the firmest texture, and let them sit at room temperature for a few minutes before serving.
Tips for Success
- Use a completely dry bowl and spatula because even a small amount of water can make melted chocolate turn thick and grainy.
- Do not rush the melting process. Low heat and frequent stirring help prevent scorched chocolate.
- Let the chocolate cool briefly before adding the marshmallows so they remain distinct in the finished candy.
- Use a cookie scoop or quarter-cup measure to make the clusters similar in size and help them set evenly.
- Store the finished candy in an airtight container and keep it away from heat, sunlight, and strong odors in the refrigerator.
Equipment Needed
- Large microwave-safe bowl or heatproof bowl
- Silicone spatula
- Parchment-lined baking sheet
Variations
- For a slightly more bittersweet candy, use all semi-sweet chocolate chips while keeping the total amount of chocolate the same.
- Add a small amount of flaky sea salt on top of each cluster before chilling for a salty-sweet finish.
- Replace part of the peanuts with roasted almonds or cashews if you prefer a different nut texture.
- Stir in a small amount of crisp rice cereal with the peanuts and marshmallows for extra crunch.
- Make smaller tablespoon-size clusters for a candy tray, reducing the chilling time if the pieces are especially small.
Serving Suggestions
Serve the clusters chilled or let them stand at room temperature for 5 to 10 minutes before eating. Arrange them on a lined tray for a party or place each piece in a small candy cup for gifting. Because the chocolate softens in warm conditions, keep the serving plate away from direct sunlight and hot kitchen appliances.
FAQs about Peanut Marshmallow Clusters Candy
Can I melt the chocolate on the stovetop? Yes. Put the chocolate chips and vegetable oil in a heatproof bowl over a saucepan of barely simmering water. Stir often until smooth, making sure the bottom of the bowl does not touch the water and no steam or water gets into the chocolate.
Why did my chocolate become thick and grainy? Chocolate can seize when it comes into contact with water or overheats. Use a dry bowl and utensils, keep the heat low, and stir frequently. If the chocolate is only slightly thick, remove it from the heat and stir gently for a minute before continuing.
Can I use large marshmallows? Mini marshmallows are easiest because they distribute evenly through the mixture. If large marshmallows are all you have, cut them into smaller pieces with lightly oiled kitchen scissors before adding them.
How long do peanut marshmallow clusters keep? Stored in an airtight container in the refrigerator, the clusters are best within about 1 week. Keep them covered to prevent them from absorbing refrigerator odors and developing a dry surface.
Can I freeze these candy clusters? Yes. Place the fully set clusters in an airtight freezer container with parchment between layers and freeze for up to 1 month. Thaw them in the refrigerator while still covered to reduce condensation on the chocolate.
Final Thoughts
Peanut Marshmallow Clusters are a dependable homemade candy when you want something quick, rich, and easy to portion.
