Ingredients List
Here’s what you’ll need to create this dreamy Marshmallow Swirl Fudge:

How to Prepare Marshmallow Swirl Fudge
Get ready to dive into the delicious process of making Marshmallow Swirl Fudge! It’s so simple, and I promise you’ll be amazed at how quickly it comes together. Just follow these steps, and you’ll be savoring this sweet treat in no time!
Step-by-Step Instructions
- First things first, grab a saucepan and combine the 2 cups of semi-sweet chocolate chips and 1 cup of sweetened condensed milk over low heat. You want to melt this slowly, so be patient – it should take about 5-7 minutes. Stir it gently to avoid burning.
- Once the chocolate is fully melted and smooth, remove the saucepan from the heat. This is the moment to add in your 1 teaspoon of pure vanilla extract. Stir it well to infuse that lovely flavor throughout the fudge.
- Now, here comes the fun part! Fold in the 1 cup of mini marshmallows and the optional 1/2 cup of finely chopped nuts, if you’re using them. Be gentle while mixing; you want those marshmallows to stay fluffy and not completely melt away.
- Next, line an 8×8 inch baking dish with parchment paper for easy removal later. Pour your chocolate mixture into the dish and spread it evenly. This is where you can get creative and swirl the marshmallows a bit if you want!
- Now, it’s time to pop that fudge into the refrigerator. Let it chill for at least 2 hours until it’s fully set. I know it’s hard to wait, but trust me, it’s worth it!
- Once it’s set, take it out and cut it into squares. You’re going to love how pretty and delicious they look!

Tips for Success
To ensure your Marshmallow Swirl Fudge turns out perfectly every time, here are some handy tips that I’ve picked up along the way:
- Keep the heat low: Melting chocolate can be tricky, so always use low heat and stir gently. This prevents any burning and keeps your fudge smooth and creamy.
- Use fresh ingredients: Fresh chocolate chips and marshmallows make a big difference in flavor and texture. If you have old chocolate lying around, it might not melt as well.
- Let it chill completely: I know waiting is hard, but giving the fudge at least 2 hours in the fridge is key for it to set properly. You want those squares to hold their shape!
- Storage is simple: Store your fudge in an airtight container at room temperature for up to a week. If you want to keep it longer, pop it in the fridge – it will last up to two weeks!
- Experiment with flavors: Feeling adventurous? Try swapping half the chocolate chips for white chocolate or add a pinch of sea salt on top for a sweet and salty combo. You can even throw in some crushed peppermint candies for a festive twist!
- Cut with care: When it’s time to slice your fudge, use a sharp knife and clean it between cuts for nice, clean squares. This way, your fudge will look as good as it tastes!

FAQ Section
Got questions about making the perfect Marshmallow Swirl Fudge? Don’t worry, I’ve got you covered! Here are some common queries I often hear, along with my answers to help you out:
- Can I store leftover fudge? Absolutely! Just keep it in an airtight container at room temperature for up to a week. If you want it to last longer, pop it in the fridge, and it’ll stay good for up to two weeks. Just be sure to let it come to room temperature for the best texture when you’re ready to enjoy it again!
- What if I don’t have sweetened condensed milk? No problem! You can substitute it with a homemade version by mixing 1 cup of milk with 1/3 cup of sugar and heating it until the sugar dissolves. Just keep stirring until it thickens slightly, and you’ll get a similar result!
- Can I use different types of chocolate? Yes, feel free to experiment! Dark chocolate, milk chocolate, or even white chocolate can be used. Just remember, each type will give a different flavor profile, so choose based on your preference!
- What if I want to add flavors or extras? Go for it! You can mix in some crushed nuts, dried fruits, or even a dash of espresso powder for a mocha twist. Just keep in mind that adding ingredients might affect the texture a bit, so don’t overdo it!
- How do I know when the fudge is set? After chilling for at least 2 hours, the fudge should be firm enough to hold its shape when you cut it. If it’s still too soft, pop it back in the fridge for a little longer. Patience is key!
- Can I freeze this fudge? Yes! You can freeze it for up to three months. Just wrap it tightly in plastic wrap and then in foil, or store it in a freezer-safe container. Defrost it in the fridge overnight before enjoying.
