Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Prepare the Baking Pan
Start by taking an 8×8-inch baking pan and lining it with parchment paper, leaving some excess paper hanging over the edges for easy removal later. This will ensure your Marshmallow Swirl Fudge comes out cleanly and retains its beautiful shape.
Step 2: Melt the Chocolate Mixture
In a medium saucepan, combine the sweetened condensed milk and semi-sweet chocolate chips over low heat. Stir constantly for about 5-10 minutes until the mixture is smooth and fully melted, with no lumps remaining. You’ll know it’s ready when you can see a glossy sheen develop on the chocolate mixture.
Step 3: Add the Vanilla Extract
Remove the saucepan from the heat and stir in the vanilla extract immediately, mixing until it’s fully incorporated and aromatic. This step adds a delightful depth to your Marshmallow Swirl Fudge, elevating its flavor profile.
Step 4: Fold in the Marshmallows
Quickly fold in the mini marshmallows using a spatula, being careful not to completely melt them. You want the marshmallows to maintain their shape while creating those lovely swirls throughout your fudge mixture; this should take just a minute to gently blend.
Step 5: Pour into the Pan
Pour the fudge mixture into your prepared baking pan, using a spatula to spread it evenly into the corners. For a lovely visual effect, you can gently swirl the top with a spoon or knife without overmixing, showcasing the chunks of marshmallows peeking through.
Step 6: Cool and Set
Let the fudge cool at room temperature for about 10 minutes before transferring it to the refrigerator. Allow it to chill for at least 2 hours, or until it is firmed up completely. This step is crucial for achieving that perfect, sliceable texture for your Marshmallow Swirl Fudge.
Step 7: Cut and Serve
Once set, use the parchment paper to lift the fudge out of the pan. Place it on a cutting board and, with a buttered knife, cut it into 16 squares. This will help ensure clean edges for your delicious Marshmallow Swirl Fudge, making it ready to be enjoyed by all!

Marshmallow Swirl Fudge Recipe FAQs
What type of chocolate should I use for the fudge?
For the best flavor and texture, I recommend using semi-sweet chocolate chips as they melt beautifully and create a rich chocolate base. However, if you prefer a deeper chocolate flavor, dark chocolate chips are a great alternative!
How can I tell if my marshmallows are fresh enough?
Fresh marshmallows should be soft and pillowy without any dark spots or hardening. If you find them stale or tough, it’s best to replace them, as fresh marshmallows provide the delightful gooeyness that’s so appealing in Marshmallow Swirl Fudge.
How do I store leftover fudge?
Simply place your Marshmallow Swirl Fudge in an airtight container at room temperature for up to 7 days. For optimal freshness, separate layers with parchment paper to prevent them from sticking together.
Can I freeze Marshmallow Swirl Fudge?
Absolutely! To freeze, tightly wrap the fudge in plastic wrap and then place it in an airtight container. This way, it can last up to 3 months in the freezer. When you’re ready to indulge, just transfer it to the fridge overnight to defrost—no need for any reheating!
What can I do if my fudge isn’t setting properly?
If your fudge is soft or too gooey after chilling, it could be due to insufficient cooling time or not stirring the chocolate mixture enough while melting. To fix this, return the pan to low heat, add a bit more chocolate, and stir until fully melted and combined. Chill again until firm.
Is there a way to make this fudge dairy-free?
Indeed! To transform this recipe into a dairy-free version, simply use coconut milk and dairy-free chocolate chips in place of sweetened condensed milk and semi-sweet chocolate chips. This way, everyone can enjoy the same delightful Marshmallow Swirl Fudge!
