What is Fantasy Fudge?

Fantasy Fudge first originated as a fudge recipe on the back of the Kraft marshmallow creme jar. The original fantasy fudge recipe became a popular dessert staple during the holidays and for special occasions. It is traditionally a chocolate fudge made with condensed milk, granulated sugar, semi-sweet chocolate chips, butter, vanilla extract, marshmallow cream and walnuts.

How to make Fudge with Marshmallow Fluff

This is the perfect fudge recipe to make during the holiday season, for a Valentine’s Day treat, for a bake sale, or any time you just want to curb a chocolate craving! Follow these step-by-step instructions for delicious marshmallow creme fudge:

  1. Prep pan. Line a 8×8 or 9×9 inch square pan with aluminum foil. You can also use a 9×13 inch pan, but the fudge will be thinner. Set aside.
  1. Combine sugar, butter and milk. In a medium saucepan over medium heat, combine the sugar, butter and evaporated milk and stir constantly until fully boiling.
  1. Boil. Allow the mixture to boil, stirring constantly, for 4-5 minutes or until the candy thermometer reaches 234ºF. 
  1. Mix in remaining ingredients. Remove from the heat and add in the chocolate chips, marshmallow creme, salt and vanilla extract. Stir until fully combined.
  2. Stir in the walnuts, optional. 
  1. Add fudge to pan. Carefully pour the fudge into the prepared pan, top with more walnuts if desired. 
  2. Cool and cut. Allow the fudge to fully set and cool before cutting, 4-6 hours.

Marshmallow Fluff Fudge Recipe Tips

For best results, follow these tips:

  • Do not over cook! Over heating the fudge during the boiling process is a guaranteed way of creating dry, crumbly fudge that can’t be fixed. I recommend using a candy thermometer and cook just until the candy thermometer reaches 234ºF.
  • Cut clean slices: If you want perfectly square pieces of fudge, I recommend using a ruler and a sharp knife. Cleaning your knife between each cut will help create clean cut lines.

Store leftover fudge in an airtight container on the counter at room temperature for 2-3 weeks. You can also store it in the refrigerator for up to 4 weeks, or freeze it for up to 3 months.

Freeze fudge as a large slab or cut into pieces. For either method, place the fudge in the fridge for 1 hour to chill, then wrap the fudge tightly in plastic wrap and place inside a zip lock freezer bag. Fudge can be stored in the freezer for up to 3 months.

Fantasy Fudge Gifting Ideas

Fantasy fudge is always popular during Christmas season. I love to gift fudge to family, friends, teachers and neighbors. Here are a few ideas for using fantasy fudge for holiday gifts or other special occasions:

  • Fudge Jars: Layer fudge cubes in a glass jar and wrap with a festive ribbon. You could use just fantasy fudge, or layer it with another flavors like peanut butter fudge.
  • Fudge Tins: Use a Christmas tin or gift box and place fudge pieces inside festive cupcake holders inside the tin or box.
  • Individual Portions: If selling in a bake sale or adding to another gift, you can portion out 2 pieces of fudge stacked, wrap in clear plastic and tie it with a ribbon.

Marshmallow Fluff Fudge FAQs

What makes Fantasy Fudge grainy?

The forming of sugar crystals during the boiling process can make grainy fudge. Be sure to stir consistently, scraping the sides of the pan to prevent sugar from crystalizing, which leads to a grainy texture.

Why is my Fantasy Fudge oily?

If the butter gets too hot, it will separate and create an oily fudge. I recommend using a candy thermometer and cook just until the candy thermometer reaches 234ºF.

Why is my Fantasy Fudge too soft?

If your fudge is not cooked enough or it does not reach the target temperature, there will not be enough evaporation and water will remain, making your fudge too soft. I recommend using a candy thermometer and cook just until the candy thermometer reaches 234ºF.
