Ingredients & Why They Work

This Marshmallow Swirl Fudge Recipe only calls for a handful of ingredients, but they come together harmoniously to create that melt-in-your-mouth goodness. When shopping, aim for good-quality chocolate chips and fresh mini marshmallows for the best results.

• Semi-sweet chocolate chips: Offers a nice balance of richness and sweetness, and melts smoothly without seizing if you’re careful.
• Sweetened condensed milk: Provides moisture and sweetness plus a creamy texture that helps the fudge set perfectly.
• Unsalted butter: Adds richness and a silky finish without overwhelming saltiness.
• Vanilla extract: Enhances the chocolate flavor with warm, aromatic notes.
• Salt: Just a pinch brings out all the flavors and balances the sweetness.
• Mini marshmallows: These create those signature swirls and bursts of gooeyness that make this fudge fun and unique.

Tweak to Your Taste

One of my favorite things about this Marshmallow Swirl Fudge Recipe is how easy it is to make it your own. Over time, I’ve played with mix-ins and variations to keep things exciting—and I encourage you to do the same!

• Dark Chocolate Variation: Swapping semi-sweet for dark chocolate gives the fudge a richer, more intense flavor that mingles beautifully with the sweetness of the marshmallows—I’m addicted to this combo on cold evenings.
• Add Crunch: I sometimes toss in chopped nuts or crushed peppermint candies for a fun texture contrast.
• Vegan Twist: If you’re dairy-free, using vegan chocolate chips and condensed coconut milk can work surprisingly well.

Step-by-Step: How I Make Marshmallow Swirl Fudge Recipe

Step 1: Prep Your Pan for Easy Removal

Start by lining your 8×8-inch baking pan with parchment paper, leaving a little overhang on two sides—this makes lifting the fudge out easier later on. Trust me, trying to dig fudge out without parchment is one of those frustrating learning moments I’ve had more than once!

Step 2: Gently Melt Chocolate Mixture

In a medium saucepan over low heat, combine the chocolate chips, sweetened condensed milk, butter, and salt. Stir constantly with a silicone spatula to avoid burning. The trick here is patience: melting slowly keeps the chocolate silky smooth and stops it from seizing. You’ll know it’s ready when the mixture is glossy and lump-free.

Step 3: Stir in Vanilla

Remove the saucepan from heat and stir in the vanilla extract. This little addition makes the chocolate pop with warm, inviting flavor—don’t skip it!

Step 4: Fold in the Marshmallows

Quickly add in the mini marshmallows and fold them gently to create swirls. You want these soft pockets of marshmallow flavor dotting your fudge, not disappearing entirely—so stir just enough to combine without melting them fully. This part always feels so rewarding when you start seeing those pretty swirls form.

Step 5: Pour, Swirl, and Chill

Pour your fudge mixture into the prepared pan and use your spatula to gently swirl the top, letting some marshmallows peek through. After letting it cool a bit on the counter, pop it into the fridge for at least 2 hours or until fully set. I usually make this part ahead of time because patience definitely pays off here.

Step 6: Slice and Enjoy

Carefully lift the fudge from the pan using the parchment paper overhang. Use a buttered knife to cut it into 16 neat squares—the butter helps keep the knife from sticking for clean cuts. Then grab your favorite mug and dig in!

How to Serve Marshmallow Swirl Fudge Recipe

Garnishes

I usually keep it simple with a light dusting of crushed peppermint on top for a festive look and a hint of freshness, especially around the holidays. A few sea salt flakes sprinkled on top can take it to the next level if you love that sweet-salty combo.

Side Dishes

This fudge pairs perfectly with a hot cup of coffee or tea—I find the bitterness balances the sugar wonderfully. For a classic indulgence, serve it alongside a glass of cold milk or even some whipped cream for extra decadence.

Creative Ways to Present

For parties, I’ve arranged fudge squares on a tiered platter decorated with fresh mint leaves or edible flowers, making it eye-catching and inviting. You can also place individual pieces in festive mini cupcake liners for easy grab-and-go treats. These subtle touches make this simple fudge feel super special!

Make Ahead and Storage

Storing Leftovers

I store leftover fudge in an airtight container, layering pieces between parchment paper to keep them from sticking together. It stays fresh and chewy in the fridge for up to a week, which means you can savor it slowly without worrying about it going bad.

Freezing

Freezing works like a charm for this fudge! I cut it into squares, layer parchment paper between them, and freeze in an airtight container for up to three months. When you want a treat, just move it back to the fridge the night before to thaw gently.

Reheating

If your fudge gets a bit firm from refrigeration, I find leaving it at room temperature for about 15 minutes softens it nicely before serving. I generally avoid microwaving so it doesn’t become oily or lose its texture.
