Ingredients in Peanut Butter Fudge
Have you heard of fantasy fudge? It’s a type of fudge made with marshmallow cream that’s been around forever. The original recipe was printed on the back of the marshmallow cream jar but now there are thousands of variations.
- Granulated Sugar
- Milk: use whole milk, no substitutions
- Marshmallow Cream: also called marshmallow fluff
- Peanut Butter: use a regular processed peanut butter like Skippy or Jif. Do not use a natural peanut butter.
Marshmallow cream is what gives this fudge it’s amazing creamy texture. If you’ve ever tried marshmallow cream you already know it’s light and fluffy and when you combine that with peanut butter you end up with a rich and creamy fudge!
How to make EASY Fudge
- Prepare: Line an 9-in. square pan with foil and spray with nonstick cooking spray. Assemble all your ingredients because this recipe goes fast.
- Boil: Combine sugar and milk in a 3-quart saucepan. Bring it to a boil over medium heat, stirring constantly. Make sure it is at a ROLLING boil. Once it starts to boil, boil for 3 minutes, stirring constantly. Remove from heat.
- Stir: Immediately stir in peanut butter and marshmallow creme until blended. Immediately spread into prepared pan; cool slightly.
- Refrigerate: Refrigerate until firm. Using foil, lift fudge out of pan. Remove foil; cut into squares.
- Store: Store between layers of waxed paper in an airtight container. It will keep for a few weeks in the refrigerator.
Why this recipe works:
- I’m so excited about this easy fudge recipe because it’s foolproof! It’s so easy to make and it works every time.
- Unlike other recipes, you don’t need a candy thermometer to make this fudge. No special equipment needed! You only need a saucepan and a baking dish.
- You only need four ingredients and about 10 minutes to make it! It’s a great recipe for the holidays when you need a batch of something sweet on short notice.
- This fudge starts to set immediately and is ready to slice after an hour in the fridge.
Grainy fudge usually happens because the sugar has not completely dissolved into the milk. Be sure to stir well and continuously while the milk and sugar boil to ensure it fully dissolves.
You need to boil this fudge for three minutes. Make sure it is at a rolling boil then set your timer.
It depends on the recipe but this easy peanut butter fudge sets very quickly and is ready to slice after it’s chilled for an hour. In fact, as soon as you pour the mixture into the dish you will notice it will start to firm up almost immediately.
For this recipe, after the fudge has set, you don’t need to keep it in the refrigerator. I recommend slicing it and storing the slices in an airtight container. Separate them with wax paper and the fudge will keep well for up to a week.
This fudge can be frozen in an airtight container for up to one month.
Chances are it didn’t set because it wasn’t cooked hot enough. It needs to stay at a continuous rolling boil for 3 minutes.
You can add some powdered sugar and mix and it should help it set up. How much powdered sugar depends on how thin it is. To offset the extra sweetness, add some extra salt.
This fudge is not vegan but it is gluten-free if the marshmallow cream is gluten free – be sure to check the ingredients list.

My daughter wants peanut butter fudge for Christmas. I’m going to make her your peanut butter fudge. Thanks
I followed the directions carefully but the end product was crumbly. Tasted good but not presentable for gifts. Would not make again.
You overcooked it, that’s why it’s crumbly. No fault of the recipe.
Thank you for your peanut butter recipe easy and tastes great
Made this recipe today. Used 2% milk since that is what I had. Poured onto parchment paper on counter top and let set. Turned out great. Recipe is easy and quick. Will be keeping this and using again.
So glad you liked it!
My peanut butter recipe used in past years is now just too sweet. So I spent a large part of an afternoon online looking through recipes which I felt would better meet current tastes, including quick and easy preparation! After looking at many recipes and reviews–from old fashioned to newer recipes–this “Foolproof” one got my attention. And I scored! I made it per the recipe (except I didn’t have whole milk so used half evaporated and half water) and it is perfect! Was so easy and quick, perfect sweetness, and the overall texture and taste are absolutely the best!! My husband was very impressed, and I can’t wait to share it with others. Thank you so much, Dorothy Kern, for what is now my one and only peanut butter fudge recipe!
What size jar of marshmallow creme are you using? Thanks!
The small jar, I believe it’s 7 oz
I thoroughly enjoy peanut butter fudge, and this recipe looks so easy and the fudge looks so yummy . . . I can’t wait to make some!! However, I am (like a few others have commented) seeing vanilla in the picture of ingredients but do not see it listed in the recipe. The comment was made the recipe would be amended to show that. I guess my question is . . . is the vanilla necessary? If so, please amend the recipe to show how much. Thank you!!
I see where reviewers have asked about the vanilla and you said you would correct the recipe I don’t see the corrected recipe so how much vanilla and when do you add it? Thanks for your recipes, Karen
Hi, Dorothy—I can’t wait to try this recipe, but I was wondering…since I love PNButter-Chocolate fudge the most, do you think I could add melted chocolate chips to your recipe? Or, would this totally mess it up? Thank you for your help—or from any of the Commenters, as well!🙏🏻
Umm…I noticed you said to reduce the powdered sugar in several of the comments, yet the recipe calls for granulated, excepting when trying to thicken fudge which didn’t set. So – which is the correct sugar?
I also saw an earlier comment asking when to add the vanilla, to which you replied at the very end. The problem is – there’s no vanilla listed or shown anywhere in this recipe.
Would you please be so kind as to clarify both of these, as I’d like to make a batch for our Thanksgiving dessert tray.
Thanks so much, from Terry the Confused 😂 in Alberta, Canada 🇨🇦
In the photos of the ingredients, it shows vanilla flavoring but it is not mentioned in the recipe. Also some of the reviewers say they used powdered sugar, but the ingredients list granulated sugar. Can you clarify? Thank you!
Sorry about that – the vanilla goes in at the end, I’ll edit the recipe. It’s granulated sugar – I have never used powdered.
Can I use marshmallows, if so how much?
I’m afraid that would be a different recipe – I haven’t tried it. Fudge is so finicky I don’t suggest substitutions.
