Step‑by‑Step Instructions for Creamy Marshmallow Swirl Fudge to Satisfy Your Sweet Tooth
Step 1: Melt the Base
In a medium saucepan set over low heat, combine semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Stir continuously for about 5-7 minutes until the mixture becomes smooth and glossy, ensuring no chocolate is scorched. This will be the rich foundation of your Creamy Marshmallow Swirl Fudge.
Step 2: Add Flavor Enhancements
Once the fudge base is melted, remove the saucepan from heat and stir in the vanilla extract and a pinch of salt. Mix thoroughly until these flavor enhancers are well incorporated. The warm mixture should maintain its silky consistency, allowing the flavors to meld beautifully, contributing to the delightful taste of your Creamy Marshmallow Swirl Fudge.
Step 3: Prepare the Baking Dish
Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal later. Carefully pour the melted fudge mixture into the prepared dish, then use a spatula to spread and smooth it evenly. The fudge should fill the dish uniformly, creating a flat surface that will support the gorgeous marshmallow swirls.
Step 4: Swirl in the Marshmallow Fluff
Spoon dollops of marshmallow fluff over the fudge layer. With a knife or skewer, gently swirl through the mixture to create a marbled effect. Be cautious not to overmix, as you want distinct ribbons of marshmallow fluff visible throughout your Creamy Marshmallow Swirl Fudge, adding an inviting visual appeal.
Step 5: Chill to Set
Cover the baking dish with plastic wrap or aluminum foil and refrigerate for at least 2 hours, allowing the fudge to firm up. The chilling process is crucial, as it transforms the luscious mixture into a sliceable treat. Check for a slightly set texture before proceeding to the next step.
Step 6: Cut and Serve
Once the fudge has chilled completely, lift it out of the dish using the parchment paper overhang. Transfer to a cutting board and slice it into 1-inch squares for serving. The final result should present a beautiful contrast of rich chocolate and fluffy marshmallow swirls in each piece of your Creamy Marshmallow Swirl Fudge.

Make Ahead Options
These Creamy Marshmallow Swirl Fudge squares are perfect for meal prep, allowing you to indulge in a sweet treat whenever cravings strike! You can prepare the fudge mixture up to 24 hours in advance before chilling it. Simply follow the initial steps to melt the chocolate base and swirl in the marshmallow fluff as usual, then cover the dish tightly with plastic wrap and refrigerate. To maintain quality, ensure the fudge is well-wrapped to prevent it from absorbing odors in the fridge. When ready to serve, simply remove it from the fridge, cut into squares, and enjoy your delightful homemade dessert with minimal last-minute effort!
