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.

THERE WEREN’T ANY MEASUREMENTS FOR THE INGREDIENTS!! I don’t know how I’m supposed to make anything without knowing how much of an ingredient I’m supposed to put in something. Maybe they’re on there and I just can’t see them for some reason? But I’m pretty pretty sure that’s not the case. Just kinda wondering how you could’ve gotten 5⭐ without measurements? Anyway, I I just thought you might want to know that you don’t have the measurements on here! I would really love to try to make this fudge cuz it sounds delicious! I hope you have a very blessed safe Christmas and your best year yet! THANKS FOR SHARING YOUR RECIPE, even if I couldn’t make it 😢
