Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Prep the Pan
Begin by lining an 8×8-inch square baking pan with parchment paper, leaving some overhang on the edges. This will make it easier to lift the fudge out later. Make sure the parchment fits snugly into the corners of the pan to hold the fudge shape perfectly.
Step 2: Melt the Mixture
In a medium saucepan, combine sweetened condensed milk, chocolate chips, and butter. Place over low heat, stirring constantly for about 5–7 minutes or until the chocolate chips are completely melted and the mixture is smooth and silky. Remove from heat once everything is well combined and glossy.
Step 3: Add the Marshmallows
Once the fudge base is melted, quickly stir in the mini marshmallows until just combined. You want the marshmallows to maintain some shape, providing that signature swirl effect in your Marshmallow Swirl Fudge. Be gentle in your mixing to avoid breaking them apart too much.
Step 4: Transfer to the Pan
Carefully pour the fudge mixture into the prepared baking pan. With a spatula, gently spread it out to reach all corners of the pan, ensuring an even layer. Take care not to overmix, allowing the mini marshmallows to peek through for that delicious swirl effect.
Step 5: Cool at Room Temperature
Allow the fudge to sit at room temperature for about 10 minutes. This will help it slightly set before chilling. After that, transfer the pan to the refrigerator for at least 2 hours or until the fudge is firm and completely set, making it easier to slice later.
Step 6: Slice the Fudge
Once your Marshmallow Swirl Fudge has set, use the parchment paper overhang to lift it out of the pan. Place it on a cutting board and, using a buttered knife, slice the fudge into 16 squares. The butter will help prevent sticking and ensure clean edges for a beautiful presentation.

How to Store and Freeze Marshmallow Swirl Fudge
Fridge: Store your Marshmallow Swirl Fudge in an airtight container for up to 7 days. This keeps it fresh and chewy, perfect for snacking!
Freezer: For longer storage, wrap the fudge tightly in plastic wrap and place it in an airtight container, freezing for up to 3 months. This way, you’ll have a delicious treat on hand whenever the craving hits!
Layering: If freezing in layers, be sure to separate them with parchment paper to prevent sticking. This will make it easier to grab a piece whenever you want some sweetness!
Reheating: There’s no need to reheat your fudge—enjoy it cold right from the fridge or freezer for the best texture and flavor experience!
Make Ahead Options
These Marshmallow Swirl Fudge squares are perfect for meal prep enthusiasts! You can make the fudge base up to 24 hours in advance, allowing it to set overnight in the refrigerator for optimal texture. Simply prepare the chocolate mixture and cool it as instructed, then refrigerate before completing the recipe. When you’re ready to serve, stir in the mini marshmallows and pour the mixture into the pan—this step can be done right before your gathering for a freshly swirled effect. Just remember to keep the fudge stored in an airtight container to maintain its freshness, and you’ll have a delightful treat that is just as delicious as when it was first made!

Marshmallow Swirl Fudge Recipe FAQs
How do I choose the best chocolate chips for my fudge?
Opt for high-quality chocolate chips as they are the foundation of your fudge. I often use semi-sweet or dark chocolate chips for a richer taste. Check the packaging for pure chocolate options with minimal additives for the best flavor and smooth texture.
How can I store leftover fudge?
Store your Marshmallow Swirl Fudge in an airtight container in the fridge for up to 7 days. This keeps it soft and fresh for when those snack cravings hit! Be sure to keep it tightly sealed to maintain its creamy texture.
Can I freeze my fudge?
Absolutely! Wrap the fudge tightly in plastic wrap and then place it in an airtight container, freezing for up to 3 months. If you’re freezing in layers, separate them with parchment paper to avoid sticking. When ready to enjoy, simply take out a piece and let it thaw in the fridge for the best flavor.
What should I do if my fudge seems too soft after chilling?
If your fudge ends up softer than desired, it may need a bit more time in the fridge to set properly. You can also place it in the freezer for about 30 minutes for a firmer texture. Just be careful not to freeze it for too long as that might affect its creamy consistency.
Can I make any substitutions due to dietary restrictions?
Since this recipe contains dairy, it’s not suitable for vegan or dairy-free diets. However, you can use dairy-free chocolate chips and full-fat coconut milk as a substitute for sweetened condensed milk, though the texture may vary a bit. Always ensure that other ingredients like marshmallows are also dairy-free if needed.
What are the signs that my fudge has gone bad?
Keep an eye out for any dark spots or a hard texture, which can indicate spoilage. If it has an off smell or taste—toss it out! Properly stored fudge should remain fresh and delicious, just like how it should be enjoyed!
