This version takes the classic creamy fudge and packs it with M&M’s for a sweet pop of color and crunch in every bite. It’s the same white chocolate + M&M combo that makes Christmas Bark and Double Chocolate M&M Cookies so addictive, just in smooth, melt-on-your-tongue form.

Perfect for gifting, snacking, or sneaking straight from the fridge when no one’s looking.

  • Evaporated Milk

  • Butter

  • Granulated Sugar

  • Marshmallow Fluff

How To Make White Chocolate Fudge

  • Prep the pan — Butter or grease a square baking dish so the fudge releases easily once set.

  • Boil the base — Combine sugar, butter, and evaporated milk in a saucepan and bring to a rolling boil, cooking until it reaches the soft-ball stage.

  • Mix in the chocolate — Remove from heat and stir in white chocolate chips and marshmallow fluff until smooth and glossy.

  • Add flavor and candy — Mix in vanilla extract and fold in most of the M&M’s, saving a handful for the top.

  • Pour and set — Spread the fudge into the prepared pan, press the remaining M&M’s on top, and let it cool until firm.

Recipe Tips & Tricks

  • Use a candy thermometer. Make sure the sugar mixture reaches the soft-ball stage (about 234°F) for the perfect fudge texture.

  • Don’t rush the boil. Boiling for a full three minutes gives the fudge structure—cutting it short can make it too soft.

  • Work quickly after removing from heat. The mixture thickens fast, so have your white chocolate and marshmallow fluff ready to stir in immediately.

  • Try different mix-ins. Add crushed pretzels, nuts, or sprinkles for a little crunch and extra flavor.

  • Chill to set faster. Pop the pan in the fridge if you’re short on time—just let it come to room temp before cutting for cleaner squares.

How do I know when the fudge is ready to remove from heat?

Use a candy thermometer—when the mixture reaches 234°F (the soft-ball stage), it’s ready. Without a thermometer, drop a small amount into cold water; it should form a soft, pliable ball.

Can I make this ahead of time?

Yes! This fudge stores well in an airtight container at room temperature for up to a week or in the fridge for two weeks.

Why is my fudge grainy?

Grainy fudge happens if the sugar crystals form too early. Stir constantly during boiling and avoid scraping the sides of the pan once it starts to set.
