This Peppermint Swirl Fudge is a festive, melt-in-your-mouth holiday treat with a rich, creamy base and a beautiful red swirl of peppermint flavor. It’s smooth, sweet, and just the right amount of refreshing. I love making this around the holidays because it’s easy, eye-catching, and perfect for gifting or sharing.

Why I Love This Recipe

I love how this fudge is both simple and stunning. It only takes a few ingredients, doesn’t require a candy thermometer, and always gets rave reviews. The peppermint swirl gives it a cool, minty flavor that cuts through the sweetness, and the marbled design makes it feel extra special—even though it comes together in minutes.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

White chocolate chips
Sweetened condensed milk
Peppermint extract
Red food coloring (gel works best)
Pinch of salt
Optional: crushed peppermint candies for topping

Directions

I line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal.
In a saucepan over low heat (or using a microwave-safe bowl), I melt the white chocolate chips with sweetened condensed milk and a pinch of salt, stirring until smooth.
I remove it from the heat and stir in the peppermint extract.
I pour most of the fudge into the pan, leaving a few spoonfuls in the bowl.
I tint the reserved fudge with a few drops of red food coloring and stir to combine.
I drop spoonfuls of the red fudge over the white base and use a toothpick or knife to gently swirl the colors together.
I optionally sprinkle crushed peppermint on top for extra crunch and holiday flair.
I refrigerate for at least 2 hours, or until firm, then slice into squares.

Servings and timing

This recipe makes about 25 small squares and takes 10 minutes to prep, plus 2 hours to chill. It’s a great make-ahead dessert for parties or edible gifts.

Variations

I’ve used dark chocolate instead of white for a richer twist.
For extra texture, I stir in mini marshmallows or crushed cookies before swirling.
If I want a more intense peppermint flavor, I add a second dash of extract—but it’s strong, so I taste as I go.

Storage/Reheating

I store this fudge in an airtight container in the fridge for up to 2 weeks. It also freezes well—just wrap pieces in parchment and store in a sealed freezer bag for up to 3 months. No reheating needed—just let it come to room temp before serving.

FAQs

Can I use peppermint oil instead of extract?

Yes, but I use much less—peppermint oil is much more concentrated than extract. Start with just a drop or two and taste.

Do I need a candy thermometer?

Nope! This is a no-fail fudge recipe that melts and sets without any precise temperature tracking.

Can I make this dairy-free?

You can try with dairy-free white chocolate and coconut condensed milk, but texture may vary slightly. I’ve done it, and it still turns out creamy.

What’s the best way to swirl the fudge?

I use a skewer or toothpick and lightly drag it through the colored parts in a figure-eight motion for pretty marbling.

How do I cut clean squares?

I use a sharp knife and run it under hot water between slices to get neat edges without cracking the fudge.

Conclusion

Peppermint Swirl Fudge is a creamy, festive treat that’s as beautiful as it is delicious. With just a handful of ingredients and minimal effort, I can whip up a holiday-ready dessert that never fails to impress. Whether I’m gifting it or keeping it all to myself, this fudge always finds a way onto my holiday dessert tray.
