Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Prepare Your Pan
Begin by lining an 8×8-inch baking dish with parchment paper, allowing some overhang on the sides to make lifting the fudge out easier later. This step ensures that you’ll have a clean, hassle-free removal after the fudge has set. Set the lined dish aside as we begin creating the delicious layers for the Marshmallow Swirl Fudge.
Step 2: Melt the Semi-Sweet 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 each time, until it's fully melted and smooth—this will take about 1.5 to 2 minutes total. Once melted, add ½ teaspoon of vanilla extract and mix well for a rich flavor.
Step 3: Prepare the Marshmallow Mixture
In another microwave-safe bowl, mix together 1 cup of white chocolate chips, the remaining ½ can of sweetened condensed milk, 1 tablespoon butter, and 1 ½ cups of mini marshmallows. Heat this mixture in short intervals, stirring frequently, until everything is melted and combined, which should take about 2–3 minutes. Stir in ½ teaspoon of vanilla extract once smooth, creating a delightful, creamy base.
Step 4: Layer the Fudge Mixtures
Pour half of the melted semi-sweet chocolate mixture into the prepared pan, spreading it evenly across the bottom. Take spoonfuls of the marshmallow mixture and dollop them over the chocolate layer. Next, pour the remaining semi-sweet chocolate on top, ensuring you cover the marshmallow dollops. Finally, add more spoonfuls of the marshmallow mixture on top for that irresistible swirl.
Step 5: Swirl for a Marbled Effect
Using a toothpick or a butter knife, gently swirl the layers together in a marbled pattern. Be sure not to overmix; you want to maintain distinct chocolate and marshmallow swirls to make the fudge visually appealing. This step is where your Marshmallow Swirl Fudge gets its gorgeous look!
Step 6: Chill to Set
Place the pan in the refrigerator and chill for at least 2 hours or until the fudge is firm. This cooling time allows the flavors to meld together beautifully and creates the perfect texture. Keep an eye on it, and don’t touch it until it’s set, as this will lead to the best results.
Step 7: Cut and Serve
Once chilled and firm, lift the fudge out of the pan using the parchment overhang. Place it on a cutting board and slice it into small squares. Each piece will reveal the lovely swirls of chocolate and marshmallow, making your Marshmallow Swirl Fudge as delightful to look at as it is to eat.
How to Store and Freeze Marshmallow Swirl Fudge
Room Temperature: Keep your fudge in an airtight container at room temperature for up to 3 days. This will maintain its rich, creamy texture.
Fridge: For longer freshness, store in the refrigerator in an airtight container for up to 1 week. Allow it to come to room temperature before serving for the best flavor.
Freezer: You can freeze your Marshmallow Swirl Fudge for up to 3 months. Wrap the fudge tightly in plastic wrap and place it in a freezer-safe bag.
Reheating: There’s no need to reheat fudge; simply let it thaw in the fridge overnight for a delightful treat that tastes freshly made!

Marshmallow Swirl Fudge Recipe FAQs
What kind of chocolate chips should I use for the best flavor?
Absolutely! For the richest taste and texture, I recommend using high-quality semi-sweet chocolate chips. Look for brands that have a good cocoa content. This will enhance the overall flavor of your Marshmallow Swirl Fudge tremendously.
How should I store leftover fudge?
Very simple! Keep your fudge in an airtight container at room temperature for up to 3 days to maintain that delicious, creamy texture. If you want it to last longer, store it in the refrigerator for up to a week. Just remember to allow it to reach room temperature before enjoying for that freshly-made flavor!
Can I freeze Marshmallow Swirl Fudge? How do I do that?
Absolutely, you can freeze it! To do so, wrap the fudge tightly in plastic wrap to prevent freezer burn, then place it in a freezer-safe bag to ensure freshness. It can last up to 3 months in the freezer. When you're ready to enjoy it, simply let it thaw in the refrigerator overnight—easy peasy!
What should I do if my fudge isn’t setting properly?
If your fudge isn’t firming up, there are a couple of things you can try. First, ensure that you’ve allowed enough chilling time—at least 2 hours in the fridge is key! If it’s still soft, you might consider placing it in the freezer for about 30 minutes to help it firm up. If you have overmixed your fudge, that can also affect the texture, so gentle swirling is recommended.
Can I use alternative ingredients for dietary restrictions?
Certainly! If you have dietary preferences or restrictions, feel free to swap out the chocolate with dairy-free chocolate chips or use coconut cream instead of sweetened condensed milk for a dairy-free version. Lastly, always check for allergies regarding marshmallows, as some may contain gelatin; vegan marshmallows are a great substitute for those avoiding animal products!
How can I customize my fudge with add-ins?
The more the merrier! You can easily personalize your fudge by adding crushed nuts, toffee bits, or even a sprinkle of sea salt on top. Mix in about ½ cup of your favorite add-ins before layering the fudge, and you’ll have a delicious twist each time!
