Creamy Peanut Butter Fudge

  • Boil until thermometer reaches 234-degrees.
  • Remove from heat and stir in marshmallow creme, vanilla extract, and peanut butter.

This is an easy recipe. It’s almost identical to my other peanut butter fudge recipe, with chips.

They are bit amazing in their own right, but this recipe is a little more peanut buttery because you’re using the real thing.

The other recipe uses peanut butter chips and is a little sweeter. 

If you’re wanting to make fudge that really doesn’t take long, you can try the 5-minute fudge recipe.

The great thing about fudge recipes is that you can change them easily. You can add Oreos, or Reeses Pieces, or butterscotch chips. They are all really interchangeable, and of course, to die for. 

You can also double most of these recipes with ease. And, who doesn’t want to double a fudge recipe? Seriously, I’ll take it any time I can get it. 

How To Make Peanut Butter Fudge

Butter melting in a saucepan.

Add the butter to a medium-sized saucepan and let it melt on medium-high heat.

Pour the evaporated milk into the pan and stir it around together.

Add the sugar and stir it together.

Once you get the sugar stirred into the mixture, you can add the thermometer.

I do recommend a thermometer. You’re going to have a better chance of the fudge setting up correctly. That has just been my experience. 

I’ve had people ask why their fudge didn’t set up. There can be several reasons.

Altitude can have a lot to do with the fudge setting up properly, or not boiling the mixture long enough can be a problem and that’s why a thermometer comes in handy.

Fudge is one of those things that can be a little fickle. But, whatever you do, don’t let anything stop you from making the fudge.

If it doesn’t set up, just keep it at home and eat it. It will still taste really good!

Boiling fudge ingredients.

Bring the mixture to a full rolling boil and boil for 4 minutes or until the thermometer reaches 234-degrees. 

If you’re in a high altitude area, Kraft suggests subtracting 2-degrees off for every 1,000-feet above sea level.

I’m in Florida, and we are literally two feet above sea level, so I am going to keep stirring and cooking until the thermometer gets to 234-degrees.

If you choose to time the fudge instead, just make sure it’s at a full rolling boil before you start the timer. 

To know if you have a full rolling boil, the mixture should still be boiling when stirring. The big bubbles (like the photo above) helps create that rolling effect.

Here’s a pic of my thermometer. I bought it on Amazon and you’ll find the link below in the recipe card. It was only a few dollars.

You will want to get your fudge to the softball stage.

This is a great thermometer for making candy, as well. 

Note: Be sure not to let the candy thermometer touch the bottom of the pan, or you’ll get an incorrect reading.

Once you reach the desired temperature or four minutes, remove the pan from the burner and stir in the marshmallow creme. 

I always add the marshmallow creme before the peanut butter. You need all the heat you can get for the marshmallow to melt. Stir until you don’t see any more lumps.

How to Make Fudge - Peanut butter fudge is an easy and delicious treat.

Pour the fudge into a greased casserole dish.

I usually use a 9″ x 9″ pan, because I like my fudge super thick. But, you can use up to a 13″ x 9″ pan, as well. 

Old fashioned peanut butter fudge recipe is a great dish for potlucks, parties, and gifts.

Let the fudge cool for several hours. 

That’s it! Fudge is a delicious dessert any time of year.

How long will Peanut Butter Fudge last?

Peanut butter fudge will last about a week out on the counter and about two weeks in the refrigerator. 

Should I put fudge in the fridge?

Fudge is fine on the counter and doesn’t have to be refrigerated. Some people like it cold, but we like it room temperature around here. 

Why is my fudge gritty?

Most of the time when fudge is gritty the sugar hasn’t dissolved all of the way. The next time you make the fudge, be sure to cook it long enough. 

How long does it take for fudge to set?

It usually takes about three to four hours for fudge to set up all the way. Depending on the weather, it can take a little longer. If you’re in a hurry you can refrigerate the fudge and it will set up faster. 

How do you know when the old fashioned fudge recipe is ready?

There are a few different ways to test the doneness of fudge. First, when the temperature reaches 234-degrees, the fudge is done cooking.

If you don’t have a thermometer, you can start timing the fudge for four minutes when it reaches a full-rolling boil.

Another way to test the fudge is to drop some in ice cold water. If the fudge turns into a soft ball, it’s done.
