If you’re looking for an absolutely foolproof fudge recipe that tastes like it came straight from a fancy candy shop, this marshmallow fluff fudge is going to become your new go-to dessert. I absolutely love how simple this recipe is, and honestly, it’s one of those magical recipes where just a few basic ingredients transform into something that tastes incredibly indulgent and special.
The beauty of marshmallow fluff fudge is that it requires no candy thermometer, no complicated techniques, and no stress. Just a handful of pantry staples and about fifteen minutes of your time. The marshmallow fluff creates this incredibly creamy, light texture that makes this fudge completely different from traditional chocolate fudge. It’s airier, more delicate, and has this wonderful melt-in-your-mouth quality that everyone absolutely adores.
I first made this recipe years ago when I was looking for an easy dessert to bring to a potluck, and it has been a staple in my kitchen ever since. My friends and family literally beg me to make it for every gathering. The combination of rich chocolate, sweet marshmallow, and creamy butter creates this perfect balance of flavors that appeals to everyone, even the pickiest eaters.
What makes this recipe so special is how versatile it is. While the classic chocolate version is absolutely divine, you can easily customize it with different mix-ins like nuts, sprinkles, or even a drizzle of peanut butter. I’ve included some wonderful variations below that will inspire you to get creative in the kitchen.
The best part? This fudge keeps beautifully in an airtight container for up to two weeks, though I have to be honest—it rarely lasts that long in my house. It’s the perfect grab-and-go dessert, and it also makes an absolutely wonderful homemade gift. Package it up in a pretty box with some tissue paper, tie it with a ribbon, and you’ve got a gift that looks far more expensive than it actually is.
If you’re new to fudge-making, this is absolutely the recipe to start with. It builds confidence and proves that homemade candy doesn’t have to be complicated or intimidating. Once you master this basic version, you’ll feel empowered to try other fudge recipes and candy-making techniques.
For best results, make sure all your ingredients are at room temperature before you start. This ensures everything combines smoothly without any lumps or graininess. Also, don’t skip the parchment paper step—it makes removing and cutting the fudge so much easier, and cleanup is a breeze.

Ingredients
- 1 cup (2 sticks) unsalted butter
- 2/3 cup unsweetened cocoa powder
- 1/3 cup whole milk
- 1 (7-ounce) jar marshmallow fluff
- 4 cups powdered sugar
- 2 teaspoons vanilla extract
- 1/2 teaspoon sea salt
- Pinch of fleur de sel for topping (optional)
Instructions
- Line an 8×8 inch baking pan with parchment paper, allowing the edges to hang over slightly for easy removal. Set aside and make sure your workspace is clean and organized.
- Add the butter to a large saucepan and melt it over medium heat, stirring occasionally. Once melted, remove from heat and let cool for about 2 minutes.
- Whisk the cocoa powder and milk together in a small bowl until you have a smooth paste with no lumps. This step is crucial for preventing graininess in your final fudge.
- Add the cocoa powder mixture to the melted butter and stir until completely combined. The mixture should be smooth and chocolatey.
- Gently fold in the marshmallow fluff using a spatula or wooden spoon, stirring until the marshmallow is evenly distributed throughout. Don’t overmix, as you want to maintain some of the fluff’s airy texture.
- Sift the powdered sugar into the mixture in two additions, folding gently after each addition to avoid creating a cloud of sugar. This ensures even distribution and a smooth final texture.
- Add the vanilla extract and sea salt, folding until everything is perfectly combined. The mixture should be thick, smooth, and creamy.
- Pour the fudge mixture into your prepared pan and smooth the top with an offset spatula or the back of a spoon. Try to get the surface as even as possible for uniform pieces.
- If desired, sprinkle fleur de sel or sea salt flakes on top for a sophisticated finishing touch that balances the sweetness.
- Cover the pan loosely with plastic wrap or parchment paper and refrigerate for at least 4 hours, or preferably overnight, until the fudge is completely firm.
- Once set, lift the fudge out of the pan using the parchment paper overhang. Place it on a clean cutting board.
- Using a sharp knife dipped in hot water and wiped dry between cuts, slice the fudge into 16-20 pieces. Clean your knife frequently for clean edges.
- Store the finished fudge in an airtight container between layers of parchment paper at room temperature for up to 2 weeks, though it can also be refrigerated or frozen for longer storage.
