Essential Ingredients for Your M&M Marshmallow Bars
Creating these delightful **chocolate marshmallow M&M bars** requires just a few basic ingredients. The beauty lies in their simplicity, allowing the core flavors to shine while offering room for optional enhancements.
Ingredients List:
- 12 oz package semi-sweet chocolate chips: This is your base for rich chocolate flavor. You can also opt for milk chocolate chips for a sweeter bar or dark chocolate chips for a more intense cocoa experience.
- 1 cup butterscotch or peanut butter chips: These add an extra layer of flavor and creaminess. Butterscotch provides a sweet, buttery note, while peanut butter chips offer a nutty, savory contrast that pairs beautifully with chocolate.
- Optional: 1/4 cup peanut butter: If you’re a true peanut butter enthusiast and want to amplify that flavor, a touch of creamy peanut butter mixed into the chocolate base makes these bars even more decadent.
- 3-4 cups mini marshmallows: The star of the show! Mini marshmallows are perfect for even coating and distribution throughout the bars, creating that signature gooey texture. Ensure they are fresh for the best results.
- ½ cup M&M’s: We highly recommend using pastel-colored M&M’s for a truly festive look during the Easter season, but feel free to choose any color or variety that suits your mood or occasion.

Step-by-Step Guide: How to Make Chocolate Marshmallow Pastel M&M Bars
Follow these simple instructions to create your own batch of irresistible **chocolate marshmallow M&M bars**:
- Prepare Your Pan: Begin by lining an 8×8 inch baking dish with parchment paper or aluminum foil. This crucial step will make it incredibly easy to remove the bars once they’ve set. Lightly spray the paper/foil with a non-stick cooking spray to prevent any sticking, then set the prepared pan aside.
- Combine Chocolate and Optional Peanut Butter: In a large, microwave-safe bowl, combine all your chosen chocolate chips (semi-sweet, milk, or dark) with the butterscotch or peanut butter chips. If you’re adding extra peanut butter for an intensified flavor, stir it in now as well.
- Melt the Mixture: Place the bowl in the microwave and heat on high in 30-second intervals. After each interval, remove the bowl and stir the mixture thoroughly with a rubber spatula. Continue this process until the chips are completely melted and the mixture is smooth, glossy, and free of any lumps. Be careful not to overheat, as chocolate can seize.
- Coat the Marshmallows: Once your chocolate mixture is perfectly melted, add the mini marshmallows to the bowl. Stir gently but quickly, ensuring that every marshmallow is fully coated in the warm, melted chocolate. Work efficiently so the marshmallows don’t melt completely before coating.
- Transfer to Pan: Pour the marshmallow-chocolate mixture into your prepared 8×8 inch baking dish. Use your spatula to spread it evenly into a single layer, making sure it reaches all corners of the pan.
- Add M&M’s Topping: Generously sprinkle the M&M’s (especially those lovely pastel ones for holiday flair) over the top of the chocolate marshmallow mixture. Gently press them down slightly with the back of a spoon or your hand to ensure they adhere to the bars and don’t fall off when cut.
- Chill to Set: Place the baking dish in the refrigerator for 1-2 hours, or until the chocolate is completely firm and set. This allows the bars to firm up properly, making them easy to cut.
- Cut into Bars: Once thoroughly chilled and firm, lift the parchment paper/foil out of the baking dish, along with the entire block of bars. Place it on a cutting board and use a sharp knife (lightly greased if needed) to cut the confection into desired bar sizes.
- Store Leftovers: Any leftover M&M Marshmallow Bars should be stored in an airtight container in a cool place or in the refrigerator to maintain freshness and prevent melting.

Storing and Serving Your Delicious M&M Marshmallow Bars
Proper storage is key to maintaining the fresh taste and perfect texture of your homemade **M&M Marshmallow Bars**. Here’s how to best store and serve them:
- Serving: These bars are best served at room temperature or slightly chilled. If they have been in the refrigerator, allow them to sit out for 10-15 minutes before serving for a softer, chewier texture. Keep in mind that chocolate melts when exposed to warmth, so always store your bars in a cool place or the refrigerator in an airtight container, a zip-lock bag, or wrapped tightly in plastic wrap.
- Storing in the Fridge: For optimal freshness and to keep the chocolate firm, M&M Marshmallow Bars will stay delicious in the refrigerator for about 4 days. Simply pull them out whenever you’re ready for a delightful snack or to serve to guests.
- Freezing for Longer Enjoyment: Yes, you can freeze M&M Marshmallow Bars! They are excellent frozen and can last for up to 3 months, often tasting surprisingly good straight out of the freezer for a different kind of chewy treat. To prevent them from sticking together in the freezer, arrange them in a single layer or place sheets of parchment paper or wax paper between layers in an airtight container. This ensures they remain separate and easy to grab.

Creative Variations for Your M&M Marshmallow Dream Bars!
While the classic **M&M Marshmallow Bar** is perfect as is, these treats are incredibly versatile, offering endless possibilities for customization. Get creative and make them uniquely yours!
- Marshmallow Magic: Instead of traditional white mini marshmallows, experiment with colored rainbow marshmallows for an extra burst of vibrant color in your squares, especially around Easter or St. Patrick’s Day. They add a playful touch that kids will adore. Alternatively, use larger marshmallows cut into smaller pieces for a different chew.
- Textural Delights: Want to add more crunch and texture to your **chocolate marshmallow M&M bars**? Consider stirring in a variety of delightful additions. Try crushed peanut butter cups, toasted roasted peanuts, crunchy pretzels, or even shredded coconut. The options are limitless – think crushed cookies, chopped candy bars, or even a sprinkle of sea salt for a sophisticated sweet-and-salty twist.
- Nut Butter Nuances: If you’re exploring different nut butters beyond peanut butter, such as almond butter or cashew butter, ensure you use a creamy variation. The smooth consistency will blend seamlessly with the melted chocolate chips, providing the best flavor and texture in your bars. Avoid chunky varieties for a uniform mixture, unless you specifically desire that added texture.
- Chocolate Choices: Don’t limit yourself to just semi-sweet chocolate chips. Experiment with different types of chocolate for the base. White chocolate chips can create a beautiful contrast, or try dark chocolate for a richer, less sweet bar. A blend of different chocolates can also create a complex flavor profile.
- Seasonal Swaps: Beyond pastel M&M’s, customize your bars for any holiday or season. Use red and green M&M’s for Christmas, red, white, and blue for patriotic holidays, or autumn-colored M&M’s for Thanksgiving. You can also swap M&M’s for other small candies like sprinkles, mini chocolate chips, or even chopped gummy candies.
- Flavor Extracts: A few drops of a complementary extract, such as vanilla, peppermint, almond, or orange extract, stirred into the melted chocolate can elevate the flavor of your bars dramatically.

Got Extra M&M’s? If you find yourself with leftover pastel M&M’s after making these bars, don’t let them go to waste! You can easily incorporate them into other fantastic desserts. Whip up a batch of festive Easter M&M Chocolate Chip Blondies, add them to your favorite Fudgy Chocolate Chunk Brownies, or mix them into a classic chocolate chip cookie recipe for an extra pop of color and crunch. And for another bar-style treat, you might enjoy these delightful M&M Cookie Bars!
