Marshmallow Swirl Fudge Ingredients
For the Fudge
• Semi-Sweet Chocolate Chips – The main flavor base for a rich chocolate experience; opt for dairy-free chocolate for a dairy-free version.
• Sweetened Condensed Milk – This key ingredient contributes creaminess and sweetness; substitute with coconut condensed milk for a dairy-free alternative.
• Unsalted Butter – Adds richness and smoothness; make sure to melt it prior to blending with chocolate.
• Vanilla Extract – A splash enhances the overall flavor profile, making it even more delicious.
• Salt – Just a pinch balances out the sweetness and elevates all the flavors in the fudge.
For the Swirl
• Marshmallow Fluff – Infuses the fudge with gooeyness and texture; marshmallow cream can also create a similar effect.
Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Ingredients
In a medium saucepan over low heat, combine the semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Stir continuously with a spatula until the mixture is completely smooth and glossy, which should take about 5 to 7 minutes. Be attentive to avoid burning the chocolate; once melted, remove the saucepan from heat.
Step 2: Combine Flavors
Carefully add the vanilla extract and a pinch of salt to the melted chocolate mixture. Stir well until the flavors are fully blended and the enticing aroma of vanilla fills the air. This step is crucial for enhancing the overall taste of your Marshmallow Swirl Fudge, so ensure everything is thoroughly mixed.
Step 3: Prepare Pan
Line an 8×8-inch baking dish with parchment paper, allowing some overhang to easily lift the fudge later. Pour the smooth chocolate mixture into the prepared pan, using a spatula to spread it evenly. Ensure the surface is level for uniform cooling and presentation, which will make cutting into squares much easier later on.
Step 4: Swirl Marshmallow
Spoon dollops of marshmallow fluff on top of the chocolate layer, evenly spaced across the surface. Using a knife or a skewer, gently swirl the fluff into the chocolate without over-mixing, creating beautiful ribbons throughout. This step adds visual appeal and delightful gooeyness to your Marshmallow Swirl Fudge.
Step 5: Chill
Cover the baking dish with plastic wrap and place it in the refrigerator. Chill the fudge for at least 2 hours or until it is fully firm to the touch. This allows the flavors to meld beautifully while giving the fudge a perfect, set texture. Be patient—great treats take time!
Step 6: Cut & Serve
Once the fudge is set, use the overhanging parchment paper to lift it out of the baking dish. Place it on a cutting board and slice it into squares using a sharp knife. Aim for even pieces to showcase the lovely swirls of marshmallow. Your delicious Marshmallow Swirl Fudge is now ready to be enjoyed!

Make Ahead Options
These Marshmallow Swirl Fudge treats are perfect for busy home cooks who want to save time without sacrificing flavor! You can prepare the fudge mixture up to 24 hours in advance; simply follow the first four steps—melt, combine, prepare the pan, and swirl the marshmallow fluff—then cover the baking dish tightly with plastic wrap and refrigerate. This keeps the fudge fresh and maintains its creamy texture. When you’re ready to enjoy, just chill it for a couple of hours until set, then slice into squares for an effortless sweet treat. Trust me, these delicious bites are just as delightful when made ahead!
