Winter is the perfect time of year to be making a lot of fudge.

It’s delicious, it’s easy to make, and it pretty much makes everyone happy. Just say the word, and people come-a-runnin’.

For years, I have taken fudge to the kids’ school, and the ladies up front looooooved it. Trust me, if you take someone fudge, you’ve got a friend for life. I kid you not.

And homemade gifts are truly loved by people.

You can also add the fudge to a cookie tray or take it to an office party.

You don’t need a lot of ingredients (it’s a five-ingredient peanut butter fudge – yay for simple) or time to have it ready and prepped to take for gifts or eat yourself.

My biggest issue is trying not to eat it all.

Step-By-Step Instructions

Start by adding the sugar to a saucepan.

Add the milk to the saucepan and mix it together.

Most fudge calls for evaporated milk, but this recipe uses 2% milk.

Boil the fudge until it reaches 232 degrees.

Don’t get sidetracked at this stage of the recipe (speaking from experience).

The milk can easily boil over, and you’ve got a sticky mess. If it seems like the mixture is going to boil over, turn the burner down a tad.

You can time the fudge as it boils, but using a thermometer is going to work better with this recipe.

Typically, fudge is cooked until the soft ball stage, which is 234 degrees.

The first time I made this fudge I brought it a little above the soft ball stage, and it became super crumbly. So, only cook it until it gets just below soft ball stage, which is 232 degrees.

Once the sugar and milk reach 232 degrees, remove it from the heat. Next, add the mini marshmallows to the fudge mixture and stir until they are completely melted.

Add the vanilla and mix well (forgot to take a picture of that).

Pour the fudge into a greased 8-inch x 8-inch square pan. Let the fudge set up for two to three hours.

If you’re in a hurry, you can put it in the fridge to set up faster. This fudge will still be soft. It doesn’t harden up like a typical fudge. Let me tell you, it’s sooooo good. It melts in your mouth.

How To Store Crunchy Peanut Butter Fudge

Store the fudge in an airtight container or cover with plastic wrap. You can keep it at room temperature or in the refrigerator.

Fudge will last longer in the refrigerator.

Crunchy Peanut Butter Fudge is a traditional fudge recipe. It's easy to make and pretty addictive. This is one of the best fudge recipes you will find. The peanut butter crunch is surrounded by creamy soft fudge and is sure to be a hit around the holidays or any time of year. 


  • 2 cups sugar
  • 2/3 cup milk
  • 1 cup mini marshmallows
  • 1 cup crunchy peanut butter
  • 1 teaspoon vanilla extract


  1. Add the sugar and milk to a saucepan. Bring it to a boil on medium-high heat (turn it down a little if it looks like it's going to boil over).
  2. Boil until it reaches 232 degrees on the candy thermometer.
  3. Remove from heat and add the mini marshmallows. Stir until melted.
  4. Add the vanilla and crunchy peanut butter. Stir until melted.
  5. Pour into a greased 8" x 8" casserole dish and allow two to three hours to set up.


Be sure you don't allow the candy thermometer to touch the bottom of the pan, or you will get an incorrect reading.

If you want to lift the fudge out easily, you can line the bottom and sides of the pan with parchment paper.

Do not walk away from the pan while cooking because the milk can boil over fast.
