Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Prepare the Baking Dish
Begin by lining an 8×8-inch baking dish with parchment paper, ensuring the edges overhang slightly. This will allow for easy removal later. Set the prepared dish aside and gather your ingredients for the fudge, including semi-sweet chocolate chips and sweetened condensed milk, to streamline the process.
Step 2: Make the Chocolate Mixture
In a microwave-safe bowl, combine 2 cups of semi-sweet chocolate chips, ½ can of sweetened condensed milk, and 1 tablespoon of butter. Microwave the mixture in 30-second intervals, stirring after each interval until it’s fully melted and smooth. This should take about 1 to 2 minutes. Once melted, stir in ½ teaspoon of vanilla extract until well combined.
Step 3: Prepare the Marshmallow Layer
Next, in another microwave-safe bowl, mix together the remaining 1 cup of white chocolate chips, the second ½ can of sweetened condensed milk, 1 tablespoon of butter, and 1½ cups of mini marshmallows. Microwave this mixture in similar 30-second intervals, stirring frequently until everything is melted and smooth, approximately 1 to 2 minutes. Stir in the remaining ½ teaspoon of vanilla extract for added flavor.
Step 4: Layer the Fudge Mixtures
Pour half of the prepared chocolate mixture into the lined baking dish, spreading it evenly with a spatula. Dollop spoonfuls of the marshmallow mixture on top of the chocolate layer. Follow by pouring the remaining chocolate mixture over the marshmallow layer, ensuring it is spread evenly once again. Top with additional spoonfuls of the marshmallow mixture for that delightful swirl effect.
Step 5: Create a Swirl Effect
Using a toothpick or the back of a knife, gently swirl through the layers to create a marbled pattern. Be careful not to mix too thoroughly; you want to keep the distinct layers visible. The contrasting colors will result in a gorgeous presentation for your Marshmallow Swirl Fudge.
Step 6: Chill Until Firm
Finally, chill the fudge in the refrigerator for at least 2 hours, or until firm. This cooling process is essential for achieving the perfect texture. Once set, carefully lift the fudge out of the pan using the overhanging parchment paper and place it on a cutting board. Cut into squares for serving.
Expert Tips for Marshmallow Swirl Fudge
-
Use Quality Chocolate: Choose high-quality semi-sweet chocolate for richer flavor. Cheaper brands can lead to a waxy texture.
-
Microwave Carefully: Avoid overheating the chocolate mixture; stop microwaving once melted. Overheating can cause the chocolate to seize, affecting your fudge.
-
Mix Gently: When swirling the layers, be gentle. Over-mixing will blend the chocolate and marshmallow instead of creating those lovely, distinct layers in your Marshmallow Swirl Fudge.
-
Chill Properly: Allow the fudge to chill for at least 2 hours for the best texture. Cutting too soon will result in a soft, crumbly mess instead of clean squares.
-
Storage Tips: Keep your fudge in an airtight container with parchment between layers to prevent sticking. Proper storage ensures freshness for up to 2 weeks!

Marshmallow Swirl Fudge Recipe FAQs
What type of chocolate chips should I use for the best flavor?
Absolutely! For the richest flavor, I recommend using high-quality semi-sweet chocolate chips. They melt smoothly and provide that deep chocolatey taste, enhancing your Marshmallow Swirl Fudge. Cheaper brands can sometimes result in a waxy texture that isn’t as enjoyable.
How should I store leftover Marshmallow Swirl Fudge?
You'll want to store your fudge in an airtight container with layers of parchment paper between them to prevent sticking. Properly stored, the fudge stays fresh for up to 2 weeks in the refrigerator. Just make sure to keep it in a cool place to maintain its delightful texture!
Can I freeze Marshmallow Swirl Fudge?
Very! To freeze the fudge, wrap it tightly in plastic wrap after slicing and place it in an airtight container. It will keep well for up to 2 months. When you're ready to indulge, thaw the fudge by putting it in the refrigerator overnight. This way, it will be perfectly ready to serve!
What should I do if my fudge is too soft?
If you find your fudge too soft to cut cleanly, there’s a simple fix! Let it chill in the refrigerator for an additional hour or two. If it’s still soft after that, try placing it in the freezer for about 30 minutes to firm it up. Just make sure to monitor it so it doesn’t freeze solid!
Are there any dietary considerations for this recipe?
It’s important to keep allergens in mind! This Marshmallow Swirl Fudge contains dairy products (butter and condensed milk), and the chocolate chips may contain traces of nuts. If you’re making this for someone with allergies, you might want to look for allergen-free chocolate options or use a dairy substitute, such as coconut cream, when making the fudge. Enjoying treats with loved ones should always be safe and delicious!
Can I use different types of chocolate for these layers?
The more the merrier! While I love the classic combination of semi-sweet and white chocolate, you can certainly get creative! Dark chocolate for a more intense flavor or even milk chocolate for a sweeter option can work beautifully. Just keep in mind that the texture and sweetness may vary slightly based on your choices. Enjoy experimenting!
