Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Prepare Baking Pan
Begin by lining an 8×8-inch square baking pan with parchment paper, ensuring to leave a bit of overhang on the sides. This will make it easier to lift the fudge out later. Set your prepared pan aside while you gather the remaining ingredients for the Marshmallow Swirl Fudge.
Step 2: Melt Ingredients
In a medium saucepan, combine the sweetened condensed milk, chocolate chips, and butter. Place the saucepan over low heat, stirring constantly for about 5-7 minutes until the mixture is fully melted and smooth. Look for a glossy texture without any lumps to ensure a delightful fudge base.
Step 3: Mix in Vanilla
Once the fudge mixture has melted completely, remove the saucepan from the heat. Stir in the vanilla extract, mixing until well incorporated. The sweet aroma of vanilla will enhance the overall flavor of your Marshmallow Swirl Fudge, making it even more tempting as you prepare for the next steps.
Step 4: Add Marshmallows
Quickly fold in the mini marshmallows into the warm chocolate mixture. Gently swirl the marshmallows without allowing them to melt entirely; they should still maintain their fluffy shape. This creates beautiful pockets of marshmallow throughout the fudge, adding to its charm in both texture and appearance.
Step 5: Pour Mixture
Transfer the fudge mixture to your prepared baking pan, spreading it evenly using a spatula. As you pour, create gentle swirls on the surface to give it a delightful finish. This step enhances the visual appeal of your Marshmallow Swirl Fudge, making it as delectable to look at as it is to eat.
Step 6: Cooling
Allow your fudge to cool at room temperature for about 10 minutes. After that, transfer it to the refrigerator and chill it for at least 2 hours, or until it’s fully set. This cooling time is crucial as it firms up the fudge, ensuring the perfect consistency for slicing.
Step 7: Slice and Serve
Once the fudge has completely cooled and set, take it out of the refrigerator. Lift it from the pan using the parchment overhang and place it on a cutting board. With a buttered knife, slice the fudge into 16 squares, enjoying the delightful contrasts of the creamy chocolate and chewy marshmallow in every piece.

Make Ahead Options
These Marshmallow Swirl Fudge treats are perfect for meal prep, allowing you to enjoy delicious sweets with minimal last-minute effort! You can prepare the fudge up to 5 days in advance, making it an excellent choice for busy weeks or special occasions. To do this, follow the complete instructions, then let the fudge cool and set in the refrigerator. Once set, slice it into squares, and store them in an airtight container with layers separated by parchment paper to prevent sticking. When you’re ready to serve, simply take it out of the fridge and enjoy — it will taste just as delightful as the day you made it!

Marshmallow Swirl Fudge Recipe FAQs
How do I select the best chocolate chips for my fudge?
Absolutely! For the best flavor, I recommend opting for high-quality chocolate chips. A semi-sweet variety is perfect for a balanced sweetness, while dark chocolate chips can offer a more intense chocolate experience. When choosing, look for chips with a cocoa percentage above 60% for depth of flavor, or go for milk chocolate if you prefer a sweeter treat.
How should I store my leftover fudge?
For optimal sweetness preservation, store the Marshmallow Swirl Fudge in an airtight container lined with parchment paper. This prevents sticking and keeps the fudge fresh for up to 7 days in the fridge. Remember, the fridge is your friend here, but if you can’t finish it in a week, don’t worry! You can freeze the fudge for up to 3 months.
Can I freeze Marshmallow Swirl Fudge?
Yes, absolutely! To freeze your fudge, wrap it securely in plastic wrap, and then place it in an airtight container to avoid freezer burn. Simply thaw it overnight in the fridge before serving, and you’ll welcome back that creamy texture you loved! When ready to enjoy, just slice it up and indulge.
What should I do if my fudge didn’t set properly?
If your fudge hasn’t set as it should, don’t fret! Simply remelt the fudge mixture over low heat until it becomes smooth again. Then, pour it back into the pan, let it cool for a bit at room temperature, and refrigerate again for a solid 2-3 hours. This usually resolves any issues, ensuring you enjoy your fudge as intended.
Is this recipe safe for people with allergies?
Great question! This Marshmallow Swirl Fudge contains dairy (butter and sweetened condensed milk) and may not be suitable for those with lactose intolerance or dairy allergies. If you need a dairy-free version, try substituting with coconut cream and dairy-free chocolate chips. Always check labels for cross-contamination if allergies are a concern.
What if I want to add extra flavors to the fudge?
Very! Adding extra flavors is an excellent way to customize your Marshmallow Swirl Fudge. Consider mixing in a teaspoon of peppermint extract for a refreshing twist, or some espresso powder for a coffee-flavored kick. Nuts like walnuts or pecans also add delightful texture! Just remember to fold them in gently to maintain that beautiful swirl effect.
