Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt the Ingredients
In a medium saucepan, combine the semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Place the saucepan over low heat, stirring constantly for about 5-7 minutes until everything melts together into a smooth, glossy mixture. Pay attention to the texture; it should be silky without any lumps.
Step 2: Add Flavor Enhancers
Once the mixture is completely melted, remove the saucepan from the heat. Stir in the vanilla extract and a pinch of salt, mixing until well blended. This step is crucial as the vanilla adds depth to the Marshmallow Swirl Fudge, and you should notice a fragrant aroma filling the air.
Step 3: Prepare the Baking Dish
Next, line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal later. Pour the chocolate mixture into the lined dish, using a rubber spatula to spread it evenly into the corners. The fudge layer should be about an inch thick, creating a perfect canvas for the marshmallow swirls.
Step 4: Create the Marshmallow Swirls
Now it’s time to add the fun! Drop spoonfuls of marshmallow fluff over the chocolate mixture. Use a knife to gently swirl the fluff into the chocolate without overmixing. Aim for beautiful swirls that remain distinct, as the marshmallow will create those signature ribbons throughout the fudge.
Step 5: Chill Until Set
Refrigerate the fudge for at least 2 hours, allowing it to set firm. Check to ensure the fudge has a solid texture; it should feel slightly tacky but not sticky. This chilling process is essential for achieving the perfect bite, making it easy to cut into squares later.
Step 6: Cut and Serve
Once set, lift the fudge out of the dish using the parchment paper overhang. Place it on a cutting board and use a sharp knife to cut it into squares or rectangles, revealing the delightful marshmallow swirls. This Marshmallow Swirl Fudge is now ready to be enjoyed—share it with loved ones or savor it on your own!

Expert Tips for Marshmallow Swirl Fudge
-
Use Quality Ingredients: The flavor of your Marshmallow Swirl Fudge depends on high-quality chocolate chips and vanilla extract. This will enhance the overall taste.
-
Avoid Overmixing: When swirling in the marshmallow fluff, be gentle! Overmixing can result in a less visually appealing fudge with no distinct swirls.

Perfect Consistency: Make sure to let the fudge chill long enough in the fridge. If it’s not set properly, clean cuts will be impossible, leading to a messy presentation.
-
Add Texture: For an extra twist, consider adding crushed cookies or nuts on top before chilling for a delightful crunch in every bite.

Marshmallow Swirl Fudge Recipe FAQs
How do I choose the perfect chocolate chips for my fudge?
Absolutely! For the best flavor, opt for high-quality semi-sweet chocolate chips. If you’re looking for a vegan option, dairy-free chocolate chips work wonders as well. Just make sure to check the labels for any hidden dairy ingredients!
What’s the best way to store leftover Marshmallow Swirl Fudge?
I recommend storing your fudge in an airtight container in the refrigerator for up to 1 week. This keeps the fudge fresh and delectable! Place parchment paper between layers if you want to stack them, preventing sticking.
Can I freeze my Marshmallow Swirl Fudge?
Very! To freeze, cut the fudge into squares and place them in an airtight container, separating layers with parchment paper. It can last for up to 3 months in the freezer. When you’re ready to enjoy some, simply thaw the container in the fridge overnight.
Why is my fudge too soft or sticky after it sets?
Oh no! This can happen if the fudge mixture wasn’t heated long enough to melt the chocolate fully or if too much marshmallow fluff was added. Be sure to monitor your melting process between 5-7 minutes for a smooth texture. If it’s too soft after chilling, you can re-melt it gently and add a little more chocolate to thicken it up.
Is there a way to make this fudge nut-free?
Certainly! The Marshmallow Swirl Fudge is naturally nut-free as per the original recipe. However, if you’re using add-ins like nuts or crunchy toppings, just skip them to ensure it meets dietary needs. Always double-check all products to ensure they’re nut-free.
Can I use something other than marshmallow fluff for the swirls?
You can, but for the best results, I recommend sticking with marshmallow fluff for that silky smooth texture. If it’s unavailable, mini marshmallows can work, but be sure to chop them to incorporate them evenly in the fudge. Just keep in mind it won’t give the same swirl effect!
