Ingredients You’ll Need
The beauty of this Marshmallow Swirl Fudge Recipe lies in its simplicity. Each ingredient is essential, thoughtfully chosen to build deep chocolate richness, creamy sweetness, and that signature marshmallow swirl that makes the fudge truly special.
- 2 cups semi-sweet chocolate chips: The base of your fudge providing that smooth, classic chocolate flavor.
- 1 can (14 oz) sweetened condensed milk: Adds luscious creaminess and sweetness to bind the fudge perfectly.
- 2 tbsp unsalted butter (melted): Gives the fudge a rich, silky texture and subtle richness.
- 1 tsp vanilla extract: Enhances the chocolate and marshmallow flavors with warm aromatic hints.
- ¼ tsp salt: Balances the sweetness and intensifies the chocolate’s depth.
- 1 cup marshmallow fluff (or marshmallow cream): The star ingredient for those enticing swirls that make the fudge look as delightful as it tastes.
How to Make Marshmallow Swirl Fudge Recipe
Step 1: Melt the Chocolate
Start by gently melting your semi-sweet chocolate chips alongside the sweetened condensed milk and melted butter in a saucepan over low heat. Keep stirring constantly to ensure the mixture becomes smooth and glossy without scorching. This careful melting is the foundation of your luscious fudge texture.
Step 2: Add the Vanilla and Salt
Once the chocolate mixture is perfectly melted, remove it from the heat. Stir in the vanilla extract and salt until everything is completely combined. These simple additions elevate the flavors, making the fudge taste rich and well-rounded rather than one-dimensional.
Step 3: Pour into the Pan
Prepare an 8×8-inch baking dish by lining it with parchment paper, making cleanup a breeze. Pour the silky chocolate fudge base evenly into the pan. Smooth the surface gently with a spatula to create the perfect canvas for your marshmallow swirl.
Step 4: Add the Marshmallow Swirl
Drop spoonfuls of marshmallow fluff over the fudge and then, using a knife, softly drag through the mixture to create thick, beautiful swirls. Be gentle! Don’t overmix, or you’ll lose those lovely ribbons that make this fudge so visually interesting and fun to eat.
Step 5: Chill and Set
Pop the pan into the refrigerator for at least 2 hours. This chilling step is crucial for the fudge to fully set, allowing you to slice through it cleanly and enjoy those perfect bite-sized squares with a delightful gooey swirl in every piece.
How to Serve Marshmallow Swirl Fudge Recipe

Garnishes
Sprinkling your fudge with crushed graham crackers just before chilling adds a delicious crunch and a nod to s’mores, making this Marshmallow Swirl Fudge Recipe feel even more irresistible. For a caramelized touch, lightly torch the top with a kitchen torch to toast the marshmallow swirls and add a beautifully warm flavor.
Side Dishes
This fudge pairs wonderfully with a cup of rich hot cocoa or a bold coffee to balance its sweetness. If you want to go all out, serve it alongside fresh berries or a tangy fruit compote to introduce a bright contrast to the creamy, sweet fudge.
Creative Ways to Present
For a festive touch, cut the fudge into small squares and arrange them on a decorative platter with edible glitter or mini marshmallows scattered around. You can even wrap individual pieces in parchment or wax paper tied with a ribbon — perfect for gifting or party favors that everyone will rave about.
Make Ahead and Storage
Storing Leftovers
Once your fudge is fully set, store the leftovers in an airtight container in the refrigerator. It will keep fresh and flavorful for up to two weeks, making it easy to satisfy those chocolate cravings anytime.
Freezing
If you want to enjoy the Marshmallow Swirl Fudge Recipe later, wrap individual pieces tightly in plastic wrap and place them in a freezer-safe container. When frozen, it stays delicious for up to three months. Just thaw in the fridge before indulging.
Reheating
Fudge is best enjoyed chilled or at room temperature, but if you prefer it softer, let it sit out of the fridge for about 10 minutes. Avoid microwaving, which can melt the marshmallow swirls and alter the texture.
FAQs
Can I use mini marshmallows instead of marshmallow fluff?
While mini marshmallows can be used in a pinch, marshmallow fluff is preferred for this recipe because it swirls smoothly without fully melting into the fudge, creating those gorgeous distinct ribbons in the Marshmallow Swirl Fudge Recipe.
Is it necessary to chill the fudge for 2 hours?
Yes, chilling the fudge allows it to set properly, ensuring you get clean cuts and the ideal firm-yet-creamy texture that makes this fudge so delicious.
Can I substitute dark chocolate for semi-sweet chocolate chips?
Absolutely! Using dark chocolate will give the fudge a more intense, slightly bitter chocolate flavor, which pairs beautifully with the sweetness of the marshmallow swirls.
How do I prevent the marshmallow fluff from blending completely into the fudge?
The key is to gently swirl with a knife instead of stirring vigorously. This technique keeps the marshmallow ribbons thick and visible instead of mixing them fully through the fudge.
Can this recipe be doubled for a larger batch?
Yes, you can easily double the ingredients and use a larger pan. Just make sure to adjust chilling time accordingly to allow the thicker fudge layer to set properly.
