The Key to Perfect Fudge: Your Ingredients
The magic of this White Chocolate Marshmallow Fudge lies in its simplicity. With so few components, using high-quality ingredients makes a significant difference in the final taste and texture.
Choosing Your White Chocolate
The star of the show is the white chocolate, so choose wisely! For the best results, use a high-quality white chocolate bar or baking wafers (like Ghirardelli or Callebaut) that you chop yourself. These melt more smoothly than standard white chocolate chips, which often contain stabilizers that can prevent them from melting into a perfectly fluid consistency. A good white chocolate will have cocoa butter listed as one of the primary ingredients.
Mini Marshmallows vs. Marshmallow Fluff
This recipe calls for mini marshmallows, which are folded in at the end to create delightful pockets of soft, chewy texture throughout the fudge. If you prefer a completely smooth, uniform fudge, you could substitute an equal amount of marshmallow fluff, stirring it in with the white chocolate until fully melted and combined.
Step-by-Step: How to Make White Chocolate Marshmallow Fudge
Follow these simple instructions for flawless fudge every time. Make sure you have all your ingredients measured and your pan prepared before you begin, as the process moves quickly once you start melting the chocolate.
- Prepare Your Pan: Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on two sides. This will create “handles” that make it easy to lift the fudge out later.
- Melt the Base: In a medium saucepan over low heat, combine the sweetened condensed milk, butter, and salt. Stir constantly until the butter is fully melted and the mixture is smooth and heated through. Do not let it boil.
- Add the White Chocolate: Remove the pan from the heat. Immediately add the chopped white chocolate and vanilla extract. Stir continuously until the white chocolate is completely melted and the mixture is thick and glossy.
- Fold in the Marshmallows: Gently fold in the mini marshmallows. Work quickly, as you want them to soften slightly but not melt completely into the fudge.
- Chill to Set: Pour the fudge mixture into your prepared pan and use a spatula to spread it into an even layer. Let it cool at room temperature for 30 minutes before transferring it to the refrigerator. Chill for at least 3-4 hours, or until firm.
- Slice and Serve: Once firm, use the parchment paper handles to lift the fudge from the pan. Place it on a cutting board and slice it into small squares.
This fudge is delightful on its own, but it’s even better when shared. For a truly decadent dessert experience, try pairing it with one of our other popular recipes, like these amazing Fudgy Cherry Brownies.

Pro Tips for No-Fail, Creamy Fudge
Even the simplest recipes have little secrets to success. Here are a few expert tips to ensure your White Chocolate Marshmallow Fudge turns out perfectly every time.
- Work Quickly: Once the white chocolate is melted, the fudge will begin to set up fast. Have your pan ready and work efficiently to get it spread evenly before it becomes too firm.
- Low and Slow Heat: The key to melting white chocolate without it seizing or becoming grainy is to use low, gentle heat. Never let the condensed milk mixture boil.
- Don’t Overmix the Marshmallows: Fold the marshmallows in just until they are distributed. Overmixing will cause them to melt completely, and you’ll lose that lovely textural contrast.
- For Clean Slices: Use a large, sharp knife to cut the fudge. For extra clean cuts, run the knife under hot water and wipe it dry between each slice.

Fun Variations to Try
While this classic recipe is fantastic as is, it also serves as a wonderful blank canvas for your creativity. Here are a few ideas to customize your fudge:
- Cranberry Pistachio: Add 1/2 cup of dried cranberries and 1/2 cup of shelled pistachios for a festive look and a delightful sweet-tart crunch. It’s a perfect holiday combination, much like our White Chocolate Chip Cranberry Cookies.
- Peppermint Fudge: Add 1/2 teaspoon of peppermint extract along with the vanilla and top with crushed candy canes for a festive Christmas treat.
- Funfetti Fudge: Fold in 1/3 cup of colorful rainbow sprinkles with the marshmallows to create a fun, birthday-themed version.
- Toasted Coconut: Stir in 1/2 cup of toasted shredded coconut for a tropical twist and nutty flavor.
Storage and Gifting
This fudge makes a wonderful homemade gift for friends, family, and neighbors. To store, place the cut squares in an airtight container, separating layers with parchment or wax paper to prevent them from sticking. The fudge will keep at room temperature for up to one week or in the refrigerator for up to three weeks. We do not recommend freezing fudge, as it can alter the creamy texture upon thawing.
Frequently Asked Questions About White Chocolate Fudge

Yes, you can substitute marshmallow fluff for an equal amount (by volume) if you prefer a perfectly smooth fudge without the distinct marshmallow pieces. Stir the fluff in with the white chocolate until it is completely melted and combined.
Store your fudge in an airtight container to keep it fresh. It can be kept at room temperature for up to one week or in the refrigerator for up to three weeks. Separate layers with parchment paper to prevent sticking.
For the creamiest, smoothest fudge, use high-quality white chocolate bars or wafers (like Ghirardelli or Callebaut) instead of chips. Chips often contain stabilizers that can prevent them from melting perfectly, which can lead to a grainy texture.
The most common reason for fudge not setting is an incorrect ratio of liquid to solids. Ensure you are using exactly one 14oz can of sweetened condensed milk (not evaporated milk) and precisely measured white chocolate. Chilling for at least 3-4 hours is also crucial for it to become fully firm.
