It’s a creamy combo that has thick chocolate layers with peanut butter flavors.
On top of that, it has marshmallow fluff, which gives it a white and creamy texture.
Which takes the fudge recipe to the next level.
In this post, I will give you a super simple recipe that doesn’t require fancy tools or a candy thermometer.
Plus, I will also share some customization ideas like how you can make it nut-free, fluff substitutes, etc.
And how you will store it, and some pro tips to make sure that your fudge never turns grainy or dry.
What Makes This Fudge So Irresistible?
There are actually quite a few things that make this chocolate peanut butter fudge with marshmallow fluff recipe totally different as compared to other topical fudge recipes that you see on the internet.
The first thing is that marshmallow fluff gives the fudge a smooth melt-in-mouth texture that is lighter than the heavy blocky fudge that we usually get.
If you have ever made a traditional fudge using sugar and butter only, you know how easy it is to mess it up.
But when you add marshmallow creme to that, it stabilizes everything.
Secondly, the peanut butter adds a creamy, nutty contrast to rich dark chocolate, which literally balances all these whole flavors.
Lastly, it’s no fuss. Microwave or stove-top-friendly recipe.
You won’t need any thermometer stress, and also you don’t have to spend a lot of time, like spending 2 hours in the kitchen.
You can just melt, mix, swirl, and chill.
Even better, you can make it ahead for gifting parties and for late-night cravings.

Ingredients You’ll Need for Chocolate Peanut Butter Marshmallow Fudge
So here are all the simple ingredients that you need to make a chocolate peanut butter fudge with marshmallow fluff recipe.
Plus, I am also giving you some substitute options so you can try them too if they are already available in the home or just in case you want to customize them in your own way.
For the Chocolate Fudge Base:
- 2½ cups semi-sweet chocolate chips: You can also use dark chocolate chips or a chopped chocolate bar. I recommend Ghirardelli Semi-Sweet or Nestlé Toll House. If you’re a dark chocolate lover, you can go with 60–70% cocoa Lindt bars. Or any other brand, but it must be high-quality chocolate.
- 1 can (14 oz) sweetened condensed milk: This is what will give the thick, smooth texture without adding extra sugar. Eagle Brand is the classic one.
- 3 tablespoons of unsalted butter: It will make the chocolate rich and glossy.
- 1½ teaspoons vanilla extract: though it’s optional, I recommend it for a deep, warm aroma.
For the Peanut Butter Swirl:
- ½ cup creamy peanut butter: Smooth, not chunky. You can use brands like Jif or Skippy, they work great. You can also use natural peanut butter, but make sure it’s stirred well and not oily.
- 2 tablespoons butter: It will help in melting and making it spreadable.
- 2 tablespoons powdered sugar: Use it to give a little sweetness and make it more fudge-like.
For the Marshmallow Fluff Layer:
- 1 jar (7 oz) marshmallow fluff or marshmallow creme: Jet-Puffed or Kraft Marshmallow Creme both work fine. This adds a gooey, soft bite to every piece.
Optional: A pinch of salt – Just a little bit; it will enhance chocolate and peanut butter flavor. Don’t skip if your peanut butter is unsalted.

Ingredient Substitutes & Customization Tips
If you don’t have a few ingredients available, or you want to tweak this recipe a bit.
Here are some ways you can customize or swap ingredients without ruining the texture or taste.
- Nut-Free Version: You can replace peanut butter with sunflower seed butter or cookie butter. However, Cookie butter makes it rich and kind of spiced-sweet, too.
- Dairy-Free Option: You can use dairy-free chocolate chips like Enjoy Life, swap condensed milk with coconut condensed milk, and use vegan butter like Earth Balance.
- No Marshmallow Fluff?: You can melt mini marshmallows (around 2 cups) with a tablespoon of corn syrup to create a similar texture. Or you can also skip it entirely and focus on the peanut butter fudge swirl.
- Want a crunchy version?: You should add chopped roasted peanuts, or you can swirl in some crunchy peanut butter into the top layer.
How to Make Chocolate Peanut Butter Fudge with Marshmallow Fluff (Step-by-Step)
Here is how I made this Chocolate Peanut Butter Fudge with Marshmallow Fluff recipe.
You just want to follow my method, step by step, and then you can get smooth, creamy, sliceable fudge.
Step 1: Line Your Pan
You want to take a square pan and line it with parchment paper or foil.
Leave some extra overhang so that you can easily lift the fudge later.
Most importantly, grease lightly with cooking spray or a swipe of butter. Otherwise, they might stick.
But you don’t want that headache, so consider greasing.
Step 2: Make the Chocolate Fudge Base
You want to take a saucepan (or you can use a microwave-safe bowl), then combine these ingredients:
- 2½ cups chocolate chips
- 1 can sweetened condensed milk
- 3 tbsp of unsalted butter
Melt everything together over medium-low heat, but make sure to stir continuously.
Once the mixture is completely melted and smooth, you can remove it from the heat and stir in the vanilla extract.
Set aside for a few minutes while you prep the rest.
Step 3: Prepare the Peanut Butter Swirl
Now, take another small bowl and combine the following ingredients:
- ½ cup creamy peanut butter
- 2 tbsp butter
- 2 tbsp powdered sugar
Microwave it for about 20–30 seconds, or you can melt it over low heat on the stove until it’s smooth and spreadable.
Step 4: Add Marshmallow Fluff
Take your lined pan and spread the marshmallow fluff (straight from the jar) as the first layer.
It’ll be sticky….
so you have to use a spatula sprayed with a little oil, or you can simply rub some butter on it.
Then, try to spread it as evenly as you can.
Step 5: Pour the Chocolate Mixture
Now, pour the warm melted chocolate fudge mixture over the marshmallow layer.
Spread it using an offset spatula or the back of a spoon.
You can tap the pan a little on the counter to remove air bubbles and even out the top.
Step 6: Swirl the Peanut Butter
Now, you can drizzle the melted peanut butter mixture in lines or dollops over the top of the fudge.
After that, take a toothpick or knife and slowly swirl it through the top to create a marbled effect.
Note: Don’t overmix; otherwise, it’ll lose the pattern.
Step 7: Chill and Set
Finally, it’s almost ready, but now you’ve to refrigerate the whole thing for at least 3 to 4 hours, or until it’s completely firm.
However, I personally prefer keeping it in the fridge overnight.
Once it’s set, lift the fudge out using a parchment overhang and slice it into small squares.
Pro Tip: Wipe the knife clean after every slice to get clean, sharp edges.

Pro Tips to Make It Even Better
If you want your fudge to taste like it comes from the bakery or a dessert shop (which sure you want)
So, here are some of my pro tips that you need to follow.
- Use room-temperature marshmallow fluff: It can be spread more easily and won’t pull away from chocolate when slicing.
- Don’t rush the chill time: Letting your fudge set properly in the fridge gives it the perfect firm-yet-melt-in-mouth texture.
- Add flaky sea salt on top: This will give your fudge a little sweet-salty contrast that works amazing with both chocolate and peanut butter.
- Double batch it for gifting: This fudge lasts a week in the fridge and up to 2 months in the freezer.

If you’re making this fudge for guests or as a sweet snack platter, here are some delicious ways to pair it:
- With hot drinks: This fudge will taste amazing with black coffee, iced latte, or hot chocolate. You will like the contrast between bitter and sweet. I do.
- On dessert boards, You can serve it with cookies, pretzels, strawberries, and mini donuts.
- With ice cream: Chop a few pieces and toss over vanilla or chocolate ice cream for an epic sundae-style dessert.
- Crushed inside milkshake: Yup, this works too. You just have to blend it in your milkshake, and it will add chunks of peanut-buttery goodness.
Storage & Shelf Life
Here’s how you can keep this fudge fresh:
- In the fridge: You want to use an airtight container to keep it safe for about 1 week. Also, stack layers with parchment between them.
- In the freezer: You can freeze your homemade fudge for up to 2 months. However, you have to wrap pieces individually in wax paper or plastic wrap before placing them in a zip-top bag or box.
- Room temperature: You can leave it out for a few hours at a party or event. But otherwise, keep it chilled to maintain texture.
