Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt the Chocolate Mixture
In a medium saucepan, combine the semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Place the saucepan over low heat, stirring constantly for about 5 minutes until the mixture is completely smooth and glossy, ensuring no chocolate chips remain. This creamy chocolate base is the heart of your Marshmallow Swirl Fudge.
Step 2: Add Flavoring
Remove the saucepan from heat and stir in the vanilla extract and a pinch of salt. Mix until the ingredients are just combined, creating a rich flavor profile that balances the sweetness. This step is crucial to enhance the fudge’s overall taste and ensure your Marshmallow Swirl Fudge has that perfect flavor kick.
Step 3: Prepare the Baking Dish
Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal later. Pour the warm chocolate fudge mixture into the prepared dish, spreading it evenly across the bottom with a spatula. The fudge should look smooth and flat, ready to be transformed into a deliciously swirled masterpiece.
Step 4: Add the Marshmallow Swirl
Dollop generous spoonfuls of marshmallow fluff over the chocolate fudge layer. Using a butter knife or skewer, gently swirl the fluff into the fudge, creating beautiful ribbons without overmixing. The key is to create just enough swirls so that the marshmallow is visible, adding that gooey texture signature to your Marshmallow Swirl Fudge.
Step 5: Chill and Set
Refrigerate the fudge for at least 2 hours or until it is firmly set. This cooling period is essential for allowing the fudge to reach the right consistency. You’ll know it’s ready when it’s completely solid and slightly firm to the touch, making slicing it into squares a breeze.
Step 6: Cut and Serve
Once your Marshmallow Swirl Fudge has set, carefully lift it out of the baking dish using the parchment overhang. Use a sharp knife to cut the fudge into squares, revealing those delightful swirls. Serve chilled for the best texture, and watch as family and friends delight in every chocolatey, marshmallow-filled bite!

Marshmallow Swirl Fudge Recipe FAQs
How do I choose the right chocolate chips for my fudge?
Absolutely! Opt for high-quality semi-sweet chocolate chips for the best flavor. Look for brands that have a rich cocoa content, as this will significantly enhance the overall taste of your Marshmallow Swirl Fudge. If you’re feeling adventurous, try dark chocolate chips for a deeper flavor or even white chocolate for a lighter twist.
What’s the best way to store leftover fudge?
Very! Store your Marshmallow Swirl Fudge in an airtight container at room temperature for up to 3 days. If you want it to last longer, refrigerate it for up to 2 weeks. Just be sure to wrap it tightly to keep its soft and chewy texture intact. If the fudge dries out, it loses that delightful melt-in-your-mouth quality.
Can I freeze Marshmallow Swirl Fudge? How?
You bet! Freezing your fudge is a fantastic way to extend its shelf life. Cut the fudge into squares and layer them between sheets of parchment paper in an airtight freezer-safe container. It can be frozen for up to 3 months. When you’re ready to enjoy it again, simply let the fudge thaw in the refrigerator overnight for the best texture.
What if my fudge doesn’t set properly? Can I salvage it?
Oh no! If your fudge hasn’t set and is still too soft after chilling for a couple of hours, don’t worry; you might be able to salvage it. Try melting the fudge again over low heat, then add a bit more melted chocolate or powdered sugar to thicken it up. Pour it back into the pan and chill once more until firm. This little fix often gives it just the right consistency!
Is this fudge pet-friendly? What about allergies?
I always recommend keeping this Marshmallow Swirl Fudge away from pets! The ingredients, especially chocolate, can be harmful to dogs and cats. For dietary allergies, ensure that whoever you’re sharing this treat with is aware of its ingredients, particularly if they have sensitivities to dairy or gluten. You can opt for a dairy-free version using coconut condensed milk and vegan chocolate chips!
