How to Make Marshmallow Fluff Fudge

Get ready to make the creamiest marshmallow fluff fudge with our easy step-by-step instructions and helpful pictures. Follow along for pro tips and tricks that guarantee smooth, chocolatey fudge every time. Let’s get started!

FIRST STEP: Line an 8×8 square pan with parchment paper, be sure the paper goes up along the sides of the baking dish with a bit of overhang.

The parchment paper makes cleaning up a snap and makes it much easier to remove from your pan when it’s time to slice into squares.

SECOND STEP: Add the butter to a 4 to 5-quart heavy-bottomed saucepan over medium heat.

Attach a candy thermometer to the side of the saucepan to keep a more accurate temperature reading.

Allow the butter to melt, then add the evaporated milk and granulated sugar. Stir constantly, even after the sugar melts, until the thermometer reaches 235°F (the softball stage).

Pro Tip

PRO TIP: To test the boiling mixture for doneness without a thermometer, drop a bit of it into a bowl of cold water. If it forms a ball that is soft enough to flatten between your fingers, the mixture is ready for cooling – this is called the softball stage.

Remove the saucepan from the heat.

THIRD STEP: Quickly stir in the chocolate chips. Add the vanilla and marshmallow fluff once the chocolate chips have melted.

Keep stirring until the marshmallow fluff is completely incorporated. Stir in the chopped walnuts.

FOURTH STEP: Carefully pour the fudge mixture into the prepared pan. Tap the sides of the baking dish to release any bubbles.

Allow the fudge to rest for 30 minutes. Chill the fudge in the refrigerator for at least three hours before slicing six rows by six rows.

Keep refrigerated until ready to serve.
