Marshmallow Swirl Fudge Ingredients
For the Fudge Base
• Semi-Sweet Chocolate Chips – Provides rich chocolate flavor; substitute with dairy-free chocolate for a vegan treat.
• Sweetened Condensed Milk – Adds sweetness and creaminess; can use coconut condensed milk for a dairy-free option.
• Unsalted Butter – Enhances the texture; can be omitted for a dairy-free version.
• Vanilla Extract – Infuses aromatic flavor into the fudge; use pure vanilla for the best taste.
• Salt – Balances sweetness and enhances overall flavor.
For the Swirls

Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt the Base
In a medium saucepan, combine the semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Heat over low, stirring constantly for about 5 minutes or until completely smooth, ensuring the chocolate doesn’t burn. You’ll know it’s ready when the mixture looks glossy and silky. Remove it from heat and give yourself a moment to enjoy that rich aroma.
Step 2: Add Flavor
Once the chocolate mixture is smooth, stir in the vanilla extract and a pinch of salt. Mix well for about 30 seconds, ensuring both flavors are evenly distributed throughout the fudge base. The salt will counterbalance the sweetness beautifully, enhancing the flavor of your Marshmallow Swirl Fudge.
Step 3: Prepare the Dish
Line an 8×8-inch baking dish with parchment paper, allowing some edges to hang over for easy removal later. Pour the melted chocolate mixture into the prepared dish, spreading it evenly with a spatula. You want a smooth and level surface, as this will be the foundation for the delightful swirls you’ll create.
Step 4: Add the Marshmallow Swirls
Dollop generous spoonfuls of marshmallow fluff over the chocolate layer, spacing them out so it’s easy to swirl. With a knife, gently swirl the marshmallow into the fudge. Aim for thick ribbons without overmixing; you want those beautiful swirls to remain visible, hinting at the gooey goodness of your Marshmallow Swirl Fudge.
Step 5: Chill Until Set
Refrigerate the fudge for at least 2 hours or until it is fully set. You’ll know it’s ready when the edges are firm and the surface has a slight sheen. The chilling time allows the flavors to meld and the fudge to achieve that perfect creamy texture we all love.
Step 6: Cut and Serve
Once set, lift the fudge out of the dish using the parchment paper edges. Place it on a cutting board and cut it into squares with a sharp knife. The Marshmallow Swirl Fudge should be smooth and creamy with lovely swirls. Serve at room temperature for the best texture and enjoy this sweet sensation with family and friends!

Make Ahead Options
These Marshmallow Swirl Fudge squares are perfect for meal prep, saving you time on busy days! You can prepare the fudge base up to 3 days in advance by melting the chocolate and combining it with sweetened condensed milk and butter. Once cooled, simply refrigerate it and keep the marshmallow fluff separate. When you’re ready to serve, just add the marshmallow swirls and chill for at least 2 hours until set. This can be done the day of serving for optimal freshness. To maintain quality, store the fudge in an airtight container in the refrigerator. This way, you can enjoy creamy, chocolatey goodness with minimal effort whenever cravings strike!

Marshmallow Swirl Fudge Recipe FAQs
What type of chocolate chips should I use for Marshmallow Swirl Fudge?
Using semi-sweet chocolate chips provides the richest flavor for this fudge. However, if you have dietary preferences or restrictions, substituting with dairy-free chocolate chips works beautifully as well. Look for high-quality chocolate for the best taste!
How should I store leftover Marshmallow Swirl Fudge?
Store your leftovers in an airtight container at room temperature for up to 3 days. If you want to keep them fresh longer, refrigerate the fudge for up to one week. This not only helps maintain flavor but can also enhance the creamy texture as it chills.
Can I freeze Marshmallow Swirl Fudge for later?
Absolutely! To freeze, first cut the fudge into squares, then wrap each piece tightly in plastic wrap. Place all the wrapped pieces into an airtight container or a freezer bag to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to enjoy it, simply thaw in the refrigerator overnight.
What should I do if my fudge doesn’t set properly?
If your fudge isn’t firm after chilling for the recommended 2 hours, it could be due to incomplete mixing or not enough chilling time. To fix this, simply return the fudge to the refrigerator for another hour or two. Alternatively, if you find it still too soft, you can try melting it down slightly and mixing in more chocolate chips or butter to thicken it up, then re-chill in a lined dish.
Is there any way to make this fudge allergy-friendly?
Certainly! To make a dairy-free version, substitute the sweetened condensed milk with coconut condensed milk. Use dairy-free butter or omit it entirely, and choose coconut cream or vegan marshmallow fluff to create marshmallow swirls. Always check labels for any potential allergens depending on your needs.
How can I enhance the flavor of my Marshmallow Swirl Fudge?
You can elevate the flavor by adding a pinch of espresso powder into the chocolate mix, which enhances the chocolate notes without tasting like coffee. Additionally, a sprinkle of sea salt on top just before serving did wonders for contrasting the fudge’s sweetness!
