Preparation Phase & Tools to Use

To create the perfect batch of Chocolate Marshmallow M&M Fudge, having the right tools will make your preparation smoother and your fudge flawless.

Microwave-safe mixing bowl: This is crucial for melting the chocolate safely and evenly without burning it.
Rubber spatula: Ideal for folding the ingredients together gently while scraping down the sides of the bowl.
8×8 inch baking pan: The go-to size for perfectly thick squares. You can use metal or glass.
Parchment paper: Ensures easy lifting and clean edges when it comes time to slice the fudge.
Refrigerator space: Since this is a no-bake recipe, chilling is essential for setting the fudge to the right consistency.

With these basics in place, you’re all set to whip up a batch of colorful, candy-studded fudge magic.

Ingredients for the Chocolate Marshmallow M&M Fudge

Every ingredient in this fudge has a job to do. Together, they bring the creamy, crunchy, melty experience that makes each bite unforgettable.

Sweetened condensed milk: Acts as the base, giving the fudge its rich, creamy consistency and perfect sweetness.
Milk chocolate chips: Melt into the milk to create the luscious chocolate body of the fudge.
Unsalted butter: Adds silkiness and depth to the melted chocolate mixture.
Mini marshmallows: Their soft, chewy texture breaks up the density of the fudge and adds that signature gooey element.
M&M candies: The star ingredient! They provide crunch, color, and a burst of classic chocolate flavor.
Vanilla extract: Just a splash rounds out the sweetness and enhances the chocolate.

How To Make the Chocolate Marshmallow M&M Fudge

Step 1: Prepare Your Pan

Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides for easy lifting later. Lightly spray with nonstick spray if desired.

Step 2: Melt the Chocolate Base

In a large microwave-safe bowl, combine the milk chocolate chips, sweetened condensed milk, and butter. Microwave in 30-second intervals, stirring after each, until completely melted and smooth.

Step 3: Stir in the Flavor

Once melted, mix in the vanilla extract. Stir well to distribute evenly through the chocolate.

Step 4: Add the Marshmallows and M&Ms

Let the chocolate cool for 1–2 minutes to avoid melting the marshmallows. Then gently fold in the mini marshmallows and about 3/4 of the M&M candies.

Step 5: Spread and Top

Pour the mixture into the prepared pan and spread it out evenly using a spatula. Press the remaining M&Ms on top to create a colorful finish.

Step 6: Chill and Set

Refrigerate for at least 3 hours, or until the fudge is firm. Once set, lift it out using the parchment paper and cut into squares.

How to Serve and Store Chocolate Marshmallow M&M Fudge

Chocolate Marshmallow M&M Fudge is best served slightly chilled or at room temperature. For parties or holidays, you can cut them into uniform squares and serve them on a decorative platter for a festive, colorful touch. They also make fantastic edible gifts—just wrap them in parchment and tie with a ribbon.

To store, place the fudge in an airtight container and keep it in the refrigerator for up to two weeks. You can also freeze it for up to three months. Simply wrap individual squares in plastic wrap, then store them in a freezer-safe bag. Thaw overnight in the fridge before serving.

Frequently Asked Questions

What type of chocolate is best for this fudge?

Milk chocolate chips are ideal for a creamy, sweet result, but you can substitute with semi-sweet or dark chocolate if you prefer a richer flavor.

Can I make this without a microwave?

Absolutely. Use a double boiler on the stovetop to melt the chocolate, butter, and condensed milk slowly, stirring constantly.

Do the marshmallows melt when mixed in?

If your chocolate is too hot, they might melt slightly. Let the chocolate cool for 1–2 minutes before stirring in the marshmallows to preserve their shape.

How do I get clean cuts when slicing the fudge?

Use a sharp knife dipped in hot water and wiped dry. Repeat between slices for neat, clean edges.

Can I use different candies?

Yes! While M&Ms bring a classic crunch and color, you can mix in Reese’s Pieces, chopped candy bars, or seasonal variations for a twist.

Is this recipe safe for kids to help with?

Definitely! It’s no-bake and fun to assemble, making it a great kitchen activity for little helpers (with adult supervision for melting).
