This foolproof peanut butter fudge with marshmallow cream is quick and easy with just 5 ingredients – it’s creamy and soft with so much peanut butter flavor! Fudge can be finicky – so use my tested recipe to make it perfectly!
This is the old fashioned peanut butter fudge you’ll remember from your childhood – that creamy soft texture and peanut buttery flavor from scratch – like the kind you get on vacation. This is the BEST peanut butter fudge recipe – it’s easy with only 5 ingredients. It’s fantastic fudge, made with marshmallow cream. You don’t need any butter or confectioners’ sugar for this recipe and it has so much amazing peanut butter flavor. Plus – it’s freezer friendly!
Why this recipe works:
- 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.
- I’ve tested this numerous times and it always works as long as I follow the directions.
Ingredients Needed
- Granulated Sugar instead of powdered sugar
- Milk: use whole milk, no substitutions
- Marshmallow Cream: also called marshmallow fluff – no substitutions
- Peanut Butter: use a regular processed (shelf-stable) peanut butter like Skippy or Jif. Do not use a natural peanut butter.
How to make Peanut Butter Fudge
- Combine sugar and milk in a 3-quart saucepan on a stove-top.
- 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.
- Immediately stir in peanut butter and marshmallow creme until blended.
- Immediately spread into a prepared 9×9-inch pan lined with aluminum foil or parchment; cool to room temperature. Then chill until firm.
Variations
- You can stir in chocolate chips or chopped nuts after stirring in the vanilla.
- We also love making chocolate fudge and easy fudge with sweetened condensed milk or 2 ingredient fudge with frosting.
- Instead of peanut butter try making my Oreo Fudge (or stir in some Oreos after the vanilla).
Expert Tips
- Be sure to have all your ingredients ready to go when you start – making fudge goes fast!
- 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.
- I do not recommend making this in the microwave.
- You can rescue soft fudge by mixing some powdered sugar. But if this fudge is cooked properly you will not need to do this.
Storage
The best way to store fudge to keep it fresh is 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.
FAQs
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.
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.

Recipe Notes
- Use a regular store peanut butter, not a natural one where you have to stir it. You can use Skippy or Jif Naturals, but not a fully natural peanut butter.
- This fudge needs to be at a rolling boil for a full 3 minutes. It will reach approximately 234°F (soft ball stage) on a candy thermometer in this time. As long as the fudge is at a full boil before you start your timer you don’t have to use a candy thermometer.
- 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 cannot be made in the microwave.
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
