Easy Making Method
- Get Your Pan Ready
- Put parchment paper in your 9x9-inch pan with extra hanging over the sides so you can lift it out later.
- Mix Your Base
- Throw butter, sugar, and half-and-half into a big saucepan over medium heat. Let it bubble gently for 4-5 minutes while you keep stirring.
- Mix in the White Chocolate
- Take it off the heat. Stir in your white chocolate chips, marshmallow crème, and vanilla right away until it's all smooth.
- Make Your Red Mix
- Melt the semi-sweet chocolate in the microwave, going 20 seconds at a time. Mix in the red food coloring until it's all bright and even.
- Make Those Pretty Swirls
- Pour the white mixture into your pan. Drop spoonfuls of the red mixture on top. Use a knife to make those fancy marble patterns.
- Let It Firm Up
- Leave it out for about 30 minutes, then stick it in the fridge for 2 hours until it's firm enough to cut.
Tricks for Perfect Fudge
Don't skimp on cheap white chocolate—it won't melt right. Get everything measured and ready to go before you start cooking. You'll need to move fast when adding chocolate and making those swirls since the mix hardens quickly. Try using gel food coloring for the brightest red. Wipe your knife clean between swirls if you want those patterns to look sharp.

Ways to Enjoy It
Slice them into small 1-inch squares so they're easy to eat. They look amazing on fancy plates for parties. Want to give them as gifts? Pack them in cute boxes with some wax paper. You can also try adding a white chocolate drizzle on top before you serve them. They'll fit right in on any dessert table or cookie platter.
Keeping It Fresh
Pop them in an airtight container and they'll stay good on your counter for a week. Put wax paper between layers so they don't stick together. Need to make them way ahead? Wrap tightly in plastic and foil, then freeze for up to 3 months. Let them thaw in the fridge overnight when you're ready to eat them. They taste best when you bring them to room temp before serving.
Frequently Asked Questions
- → What does marshmallow creme do?
It keeps the fudge soft and silky, stopping it from getting gritty or sugary over time.
- → How do I store the fudge?
Keep it sealed in a box or jar at room temperature for about 2 weeks. For extra storage time, refrigerate it and use wax paper between layers.
- → Can I swap semi-sweet chocolate for milk chocolate?
You can, but semi-sweet gives a stronger chocolate kick that pairs better with the sweetness of the white chocolate.
- → Why is the parchment paper important?
It lets you pull out the whole fudge slab easily for slicing and stops it from sticking to the pan.
- → How can I make the swirls look awesome?
Move fast while the fudge is still warm. Use a knife to swirl, but don’t overdo it or you’ll blur the colors.
