Creamy peanut butter fudge needs only four ingredients and about five minutes on the stove, and it sets into smooth, rich squares with a deep roasted peanut flavor that feels like an old time candy shop favorite.
There is no candy thermometer and no long boiling here. You melt butter and peanut butter together, stir in vanilla, fold in powdered sugar, press the mixture into a pan, and let the refrigerator do the rest.

Why This Creamy Peanut Butter Fudge Recipe Works
Powdered sugar dissolves instantly into the warm peanut butter mixture, so the fudge never turns grainy, and you skip the tricky boiling steps of traditional fudge.
Butter gives the squares a clean, sliceable set, while peanut butter supplies the flavor and the creamy body. Unsalted butter keeps you in control of how salty the finished candy tastes.
One pot and one pan are all you need, which makes cleanup quick and makes the recipe a friendly choice for beginners and for kids who want to help stir.
Ingredients for Creamy Peanut Butter Fudge
- For the base: creamy or chunky peanut butter and unsalted butter melted slowly together in a sturdy saucepan over low heat until smooth and glossy.
- For the finish: pure vanilla extract and powdered sugar, folded in until the mixture turns thick, smooth, and shiny like soft play dough.
Peanut butter. A classic creamy jar gives the smoothest fudge, and chunky peanut butter adds small crunchy bits if you like texture.
Unsalted butter. It melts into the peanut butter and sets the fudge firm once chilled, while leaving the salt level in your hands.
Vanilla extract. A teaspoon rounds out the roasted flavor, and real vanilla tastes smoother than imitation in a recipe this short.
Powdered sugar. Measure it by spooning into the cup and leveling, and sift it if the sugar looks lumpy so the fudge stays silky.
Parchment. Line the pan with parchment with a little overhang, so you can lift the whole slab out for tidy cutting.
How to Make Creamy Peanut Butter Fudge
1. Line the pan. Line an eight inch square pan with parchment, leaving extra paper on two sides to use as handles later.
2. Melt the butter. Melt the butter in a sturdy saucepan over low heat, keeping the heat gentle so the butter does not brown or burn.
3. Add the peanut butter. Stir in the peanut butter until the mixture looks smooth and glossy, then take the pan off the heat.
4. Stir in the vanilla. Add the vanilla extract and stir quickly so the flavor spreads evenly through the warm mixture.
5. Fold in the sugar. Add the powdered sugar a little at a time, folding until the mixture is thick like play dough and no dry streaks remain.
6. Press and chill. Press the fudge into the pan, level the top, and chill it in the refrigerator for about one hour before slicing.
How to Serve Creamy Peanut Butter Fudge
Lift the slab out with the parchment, warm the knife under hot water, and cut small squares, since this fudge is very rich. Serve it with coffee, or pair it with a peanut butter coffee frappe, fudgy chocolate chunk brownies, white chocolate walnut blondies, and dark chocolate mousse on a dessert board.
How to Store and Reheat Creamy Peanut Butter Fudge
Keep the fudge in an airtight container at room temperature for up to one week, or refrigerate it for up to two weeks for a firmer bite. Freeze the squares in layers separated by parchment for up to two months, and thaw them in the refrigerator before serving.
Tips and Variations for Creamy Peanut Butter Fudge
Go low and slow. Keep the heat low while melting, because scorched butter leaves a bitter note that spoils the fudge.
Choose the right jar. Use a regular creamy peanut butter rather than a natural one that separates, since oily jars can leave the fudge greasy.
Press firmly. Use the back of a spoon or a flat measuring cup to press the fudge flat, so the squares cut neatly.
Cut cleanly. Wipe the knife between cuts for smooth edges, and cut while the fudge is cold.
Flag the allergens. This candy contains peanuts and milk, so label it clearly, and keep it away from guests with a peanut allergy.
Add toppings. Sprinkle chopped peanuts, mini chocolate chips, or a pinch of flaky salt over the top before chilling.
Mind the heat. Let the pan cool slightly before adding the sugar, since a very hot mixture can turn the fudge oily.
Check trusted guidance. Read the University of Minnesota Extension guide to storing leftovers for storage advice.
Frequently Asked Questions About Creamy Peanut Butter Fudge
How do you make creamy peanut butter fudge without boiling?
Melt butter and peanut butter together, stir in vanilla, then fold in powdered sugar until thick. The sugar dissolves without any boiling.
Can I use natural peanut butter in creamy peanut butter fudge?
It works poorly because the oil separates and the fudge can turn greasy, so a regular stabilized peanut butter gives a smoother set.
Why is my creamy peanut butter fudge crumbly?
The mixture may have too much sugar or it was not pressed firmly. Press it into the pan and chill it for a full hour.
Can I double the recipe?
Yes. Use a nine by thirteen inch pan and a larger saucepan, and keep the same low heat and gradual sugar additions.
Can I freeze fudge?
