Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Ingredients
In a medium saucepan over low heat, combine 2 cups of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and ¼ cup of unsalted butter. Stir constantly for about 5 minutes until the mixture is smooth and glossy, and no lumps remain. This is the base for your decadent Marshmallow Swirl Fudge, so keep an eye on it to prevent burning.
Step 2: Add Flavors
Remove the saucepan from heat and stir in 1 teaspoon of vanilla extract and a pinch of salt until fully combined. The vanilla not only enhances the fudge’s flavor but also adds a delightful aroma. Make sure everything is incorporated well before moving to the next step; the mixture should be creamy and fragrant.
Step 3: Prepare Baking Dish
Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal later. Pour the melted chocolate fudge mixture into the prepared dish, spreading it evenly with a spatula. This will create a beautiful, smooth base where you’ll add that irresistible marshmallow swirl later.
Step 4: Swirl Marshmallow
Using a spoon, drop generous dollops of 1 cup of marshmallow fluff over the chocolate fudge in the baking dish. With a knife or a skewer, gently swirl the marshmallow into the fudge, creating a pretty marbled effect. Be careful not to overmix; you want the swirls to be visible for that delicious contrast in the final Marshmallow Swirl Fudge.
Step 5: Chill
Refrigerate the prepared fudge for at least 2 hours, or until firm to the touch. As it chills, the fudge will set perfectly, creating a delightful texture that holds its shape. You’ll know it’s ready when it feels solid and no longer jiggly in the center.
Step 6: Slice and Serve
Once set, lift the fudge out of the baking dish using the parchment paper overhang. Place it on a cutting board and slice it into squares or rectangles with a sharp knife. Enjoy this luscious Marshmallow Swirl Fudge fresh from the fridge, sharing it with friends or savoring it all for yourself!

Tips for the Best Marshmallow Swirl Fudge
Use Fluff: Ensure you use marshmallow fluff for smoother swirls instead of mini marshmallows, which can create a chunky texture.
Chill Thoroughly: Don’t rush the chilling process! Allow the fudge to set for at least 2 hours in the fridge for clean slicing.
Avoid Overmixing: When swirling in the marshmallow, be gentle. Overmixing will blend the flavors too much, losing that beautiful marbled look.
Ingredient Quality: Choose high-quality chocolate chips and sweetened condensed milk; these ingredients significantly impact the fudge’s final flavor.
Experimenting Safely: If trying variations like Peanut Butter Chocolate Swirl Fudge, keep proportions similar to ensure successful results with the same creamy fudge texture.
Make Ahead Options
These Marshmallow Swirl Fudge treats are perfect for meal prep enthusiasts! You can prepare the fudge base a full up to 1 week in advance; simply follow the initial steps to melt the ingredients, add flavors, and pour into the baking dish. After chilling the fudge, cut it into squares but hold off on adding the marshmallow swirl until just before serving. To maintain its deliciously creamy texture, store the cut fudge in an airtight container in the refrigerator. When ready to enjoy, let it come to room temperature and swirl in the marshmallow fluff for those dreamy, gooey ribbons—making it just as indulgent as if it were freshly made!
Storage Tips for Marshmallow Swirl Fudge
Room Temperature: Store in an airtight container at room temperature for up to 3 days if you prefer a slightly softer texture.
Fridge: Keep the fudge in an airtight container in the refrigerator for up to one week. This helps maintain its freshness and creaminess.
Freezer: For longer storage, freeze the fudge in an airtight container or wrapped tightly in plastic wrap for up to 2 months. Let it thaw in the fridge before serving.
Reheating: If the fudge becomes too firm after freezing, let it sit at room temperature for about 15 minutes or microwave for a few seconds to soften slightly. Enjoy every gooey bite of your Marshmallow Swirl Fudge!

Marshmallow Swirl Fudge Recipe FAQs
How should I select semi-sweet chocolate chips for this recipe?
Absolutely! Look for chocolate chips that are labeled as “semi-sweet” for that perfect balance of sweetness and rich chocolate flavor. Avoid any products labeled as “baking chocolate,” as they often have a more bitter taste. A good quality chocolate chip will elevate the fudge’s overall flavor.
How long can I store Marshmallow Swirl Fudge?
You can store your Marshmallow Swirl Fudge in an airtight container in the refrigerator for up to one week. Ensure it’s completely cooled and set before storing to maintain its creamy texture. If you prefer a softer texture, you can leave it at room temperature for up to 3 days.
Can I freeze Marshmallow Swirl Fudge?
Yes, you can freeze it for up to 2 months! To do this, wrap the fudge tightly in plastic wrap and then place it in an airtight container. When you’re ready to enjoy, let it thaw in the fridge overnight. If it’s too firm after freezing, allow it to sit at room temperature for about 15 minutes or microwave for a few seconds to soften slightly.
What should I do if my fudge doesn’t set properly?
If your fudge is too soft and doesn’t set, it could be due to not enough chilling time or improper mixing. Make sure to chill it for at least 2 hours until firm to the touch. If it’s already been chilled and still feels too soft, consider mixing in a bit more melted chocolate into the fudge base, pressing it back into the dish, and chilling again until it sets.
Is this recipe suitable for my dietary restrictions?
Very! You can make this fudge dairy-free by substituting sweetened condensed milk with coconut condensed milk and using dairy-free chocolate chips. Always check the labels for allergens if you are serving it to others, especially those with nut allergies, as different chocolate brands may vary in ingredients.
Can I use mini marshmallows instead of marshmallow fluff?
While you can technically use mini marshmallows, they won’t create the same smooth, gooey texture as marshmallow fluff. The chunks can make it difficult to swirl properly, resulting in uneven distribution throughout the fudge. I recommend using marshmallow fluff for those beautiful, creamy swirls!
