What Kind of Chocolate Should I Use?

Semi-sweet chocolate chips are my go-to, but you can easily switch things up. Want a more intense chocolate hit? Go for dark chocolate chips. Prefer something milkier and softer? Milk chocolate works beautifully here too. Just make sure you’re using good-quality chocolate since it’s the star of the show.

White chocolate can also be used for a completely different look and taste—just expect a sweeter end result. And whatever you choose, make sure it melts smoothly for that velvety texture.

Options for Substitutions

This fudge is super flexible. Don’t have M&Ms? Swap in chopped peanut butter cups, crushed Oreos, or sprinkles. No mini marshmallows? Use larger ones cut into pieces or add in crushed graham crackers for a s’mores twist.

You can even play with the base. Use white chocolate for a sweeter version, or add a swirl of peanut butter or caramel for an extra flavor punch. And for those avoiding dairy, there are great dairy-free chocolate chips and sweetened condensed coconut milk that make this recipe easily adaptable.

Ingredients for this Chocolate Marshmallow M&M Fudge

• Semi-Sweet Chocolate Chips – These form the rich, chocolatey base of the fudge. Choose a quality brand for the smoothest melt and best flavor.
• Sweetened Condensed Milk – This thick, sugary milk binds everything together and gives the fudge its signature creamy texture and sweetness.
• Butter – Just a bit helps enhance the richness and creates that silky finish.
• Vanilla Extract – Adds a subtle warmth and deepens the overall flavor profile.
• Mini Marshmallows – These little pillows add chewy texture and a nostalgic touch. Stir them in at the end so they don’t fully melt.
• M&M Candies – For crunch, color, and that unmistakable candy-coated chocolate hit. Use classic, peanut, or seasonal varieties for fun twists.
• Pinch of Salt – Just a small amount brings balance to the sweetness and enhances all the other flavors.

Step 1: Prepare Your Pan

Line an 8×8-inch or 9×9-inch square baking dish with parchment paper or foil, leaving an overhang on the sides for easy lifting later. Lightly grease it to prevent sticking.

---

Step 2: Melt the Chocolate Mixture

In a medium saucepan over low heat, combine the chocolate chips, sweetened condensed milk, and butter. Stir continuously until everything is melted and smooth. Make sure the heat stays low to avoid burning.

---

Step 3: Add Vanilla and Salt

Remove the melted mixture from the heat and stir in the vanilla extract and a pinch of salt. This step rounds out the flavor and takes your fudge from sweet to sensational.

---

Step 4: Fold in the Marshmallows and M&Ms

Let the chocolate mixture cool for a minute or two before adding the marshmallows and M&Ms. This keeps them from melting completely. Gently fold them in until well distributed.

---

Step 5: Spread and Top

Pour the fudge mixture into your prepared pan and smooth it out with a spatula. Press a few extra M&Ms and marshmallows on top to make it extra pretty.

---

Step 6: Chill Until Set

Refrigerate the pan for at least 2–3 hours, or until the fudge is firm enough to slice. For quicker setting, place it in the freezer for about an hour.

---

Step 7: Slice and Serve

Once fully set, lift the fudge out using the parchment overhang. Slice into squares with a sharp knife. Wipe the blade between cuts for clean edges.

How Long to Prepare the Chocolate Marshmallow M&M Fudge

Prep Time: This fudge is a breeze to put together. From gathering ingredients to pouring it into the pan, you’ll need only about 10 to 15 minutes. Most of the time goes into melting the chocolate mixture and folding in the fun bits like marshmallows and M&Ms.

Chill Time: The fudge does require patience while it sets. Ideally, refrigerate it for 2 to 3 hours, but if you’re in a rush, the freezer can cut that time in half. Just make sure it’s firm before slicing.

Tips for Perfect Chocolate Marshmallow M&M Fudge

• Low and slow is key when melting the chocolate. High heat can cause it to seize.
• Use parchment paper with overhang for easy lifting and clean cutting.
• Let the mixture cool slightly before adding the marshmallows and M&Ms to keep them from melting.
• Add extra toppings on top before chilling for a more colorful, eye-catching presentation.
• Use a hot knife to slice for clean, professional-looking squares.

---

Watch Out for These Mistakes While Cooking

• Overheating the chocolate: Can lead to a grainy texture. Always melt on low heat.
• Skipping the chill time: The fudge needs to fully set before cutting; slicing too early leads to a gooey mess.
• Adding marshmallows too early: This will melt them into the fudge and ruin that chewy bite.
• Using wet tools or bowls: Water and chocolate don’t mix well. Make sure everything is dry.
• Not greasing the pan or using liner: This makes it hard to remove the fudge cleanly.

What to Serve With Chocolate Marshmallow M&M Fudge?

1. A Cold Glass of Milk

3. Vanilla Ice Cream

A scoop of ice cream next to warm fudge (or room temp) makes for a dreamy dessert duo.

4. Salty Snack Mix

Pair it with something salty like pretzels or popcorn to balance the flavors.

5. Fresh Berries

Strawberries or raspberries add a tart freshness that complements the chocolate.
