Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Chocolate Mixture
In a medium saucepan, combine 2 cups of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and ¼ cup of melted unsalted butter. Heat this mixture over low heat for about 5-7 minutes, stirring continuously until everything is melted and the mixture is smooth and glossy. Be attentive to avoid burning the chocolate, which should become a rich, creamy texture.
Step 2: Combine Flavoring
Once your chocolate mixture is smooth, remove it from the heat. Stir in 1 teaspoon of vanilla extract and a pinch of salt, mixing well to ensure full incorporation. This adds a delightful depth of flavor to your Marshmallow Swirl Fudge. Allow the mixture to cool slightly, just enough to touch comfortably without it being hot.
Step 3: Prepare Baking Dish
Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal. Pour your chocolate mixture evenly into the lined dish, smoothing the top with a spatula. This forms the base for your fudge and creates a sturdy foundation for the delicious marshmallow swirls that will follow.
Step 4: Add Marshmallow Fluff
With the fudge mixture still warm, drop spoonfuls of marshmallow fluff across the top. Using a knife or a skewer, gently swirl through the chocolate mixture, creating beautiful ribbons of marshmallow. Be careful not to overmix; you want swirls to remain distinct for a visually appealing finish on your Marshmallow Swirl Fudge.
Step 5: Chill
Once you’re satisfied with the swirling, transfer the baking dish to the refrigerator. Chill the fudge for at least 2 hours, or until it is firm and set. You’ll know it’s ready when it holds its shape and is solid to the touch.
Step 6: Cut and Serve
After the fudge has chilled and set, lift it out of the baking dish using the parchment paper. Place it on a cutting board and cut it into squares of your desired size. The Marshmallow Swirl Fudge will be rich and creamy, perfect for sharing with friends and family or simply indulging yourself!

Make Ahead Options
These Marshmallow Swirl Fudge treats are perfect for meal prep enthusiasts! You can prepare the chocolate mixture up to 3 days in advance; simply melt together the chocolate chips, sweetened condensed milk, and butter, then refrigerate it in an airtight container until you’re ready to swirl in the marshmallow fluff. The marshmallow can also be added just before serving to keep it fresh and gooey. When you’re ready to enjoy your fudge, pour the cooled mixture into the baking dish, swirl in the fluff, and chill for at least 2 hours. This way, you can impress your guests with delicious, homemade fudge that tastes just as delightful as if made fresh that day!
Storage Tips for Marshmallow Swirl Fudge

Cutting: For cleaner cuts, let the fudge chill fully before slicing into squares, and consider warming your knife for a smoother glide through the rich fudge.
Serving: Bring the fudge to room temperature for about 10-15 minutes before enjoying, as this enhances the creamy texture and flavors.
