Ooooo! It is November 1st, which means I am in FULL ON HOLIDAY mode. I love making recipes for you this time of year because holiday food is the best for sharing with people you love and creating so much merriment and joy.

I must be on a peanut butter kick since I gave you Peanut Butter No Bake Cookies on Monday (perfect for gifting!) and today we have this great Peanut Butter Fudge.

Fudge is so easy to make, but there are a few tips that make it turn out perfect. So let’s get started!

Reader Review

Your peanut butter fudge recipe is delicious! We added Fall colored peanut butter M & M’s along with with halved mini Reese’s cups on the top! Thank you for sharing…this recipe is a “keeper”!

Ingredients for Easy Fudge

I have so many easy fudge recipes. They are my bread and butter at the holidays. You don’t need a thermometer to make them, and they come together so fast!

All you need is sweetened condensed milk, baking chips, and then whatever you are flavoring it with. The amounts of each vary, but that is the basic recipe.

This Jack Daniels Whiskey Fudge is my most popular easy fudge recipe.

How to Make Peanut Butter Fudge

In the Microwave

This fudge can absolutely be made just using the microwave. This is what you want to do for microwave peanut butter fudge:

  1. In a large microwave safe bowl, combine the sweetened condensed milk and peanut butter chips.
  2. Microwave for one minute at half power. Stir the mixture a lot. More than you think you need to.
  3. Continue microwaving for 15 second intervals stirring very well after each one. It will probably only need to go back in the microwave once or twice after the first interval. Do not over cook.
  4. Stir in the peanut butter and vanilla and pour into the prepared pan.

On the Stove Top

I made this easy peanut butter fudge recipe on the stove top:

  1. In a medium sauce pan over medium low heat, combine the sweetened condensed milk and peanut butter chips.
  2. Stir consistently until the mixture is smooth.
  3. Remove from the heat and stir in the peanut butter and vanilla.
  4. Pour into the prepared pan.

Either method is fine but you want to make sure that you remove it from the heat source before adding the peanut butter. It is too easy to overheat the peanut butter and then your fudge will be oily and unappealing.

Sweetened Condensed Milk vs. Evaporated Milk

I use sweetened condensed milk in a lot of really fun recipes. Everything from my Bailey’s Fudge to my Easter Egg Cookie Dough Truffles.

Inevitably I will always get at least one person who tells me the recipe never set and was way too liquidy. At the same time I have lots and lots of other people raving about it.

I have come up with the hypothesis that people are inadvertently buying evaporated milk for some of my recipes that call for sweetened condensed milk.

It is an easy mistake to make. The cans are next to each other in the grocery store and look almost identical. Please be sure to buy sweetened condensed milk. Evaporated milk will cause this recipe to fail.

Lining Your Baking Dish for Easy Peanut Butter FudgeI

It is very important to line your baking dish with something, otherwise you won’t be able to get your fudge out.

Cut two pieces of parchment paper, each three six inches wide. I love buying parchment paper that has the lines on it for easy measurement. Lay the parchment paper one on top of the other, going in opposite directions. After your fudge is set you can easily lift it out and pull off the paper.

I find parchment paper easier to pull off than aluminum foil and it makes less wrinkles in your fudge than aluminum foil. But both work!

Cutting your Peanut Butter Fudge

I was able to get 36 pieces of fudge out of this recipe. It is a rich fudge, so while the pieces you see here are on the smaller side, they are perfect.

Here’s how to get 36 pieces:

  • When ready to cut, remove the fudge from the parchment paper.
  • Trim off just enough of the edges to make straight smooth edges.
  • Cut the remaining block in half one way and then the other way so you have four large squares.
  • Each square can be cut in thirds one way and then thirds the other way so that each of the squares yields 9 pieces.

Easy Peanut Butter Fudge

Serves: 36 pieces
(tap # to scale)
Prep: 5 minutes
Cook: 5 minutes
Total: 10 minutes
This Easy Peanut Butter Fudge is only four ingredients and comes together in about ten minutes! You need this peanut butter fudge recipe in your life.

Ingredients

  • 10 ounces peanut butter chips (see note 1)
  • 14 ounces sweetneed condensed milk (see note 2)
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla extract

Instructions

  • Line an 8 by 8 inch baking dish with parchment paper or aluminum foil. (I do find that parchment paper works a little better – see notes in the pos for more details.) Set aside.
  • In a medium saucepan over medium low heat, melt the peanut butter chips with the sweetened condensed milk, stirring consistenly. Make sure the heat is not too high and you continue to scrape the bottom of the pan to prevent burning.
  • Remove the pan from the heat and stir in the peanut butter and the vanilla extract.
  • Pour into the prepared baking dish. Cover with aluminum foil and let set for four hours. This can be done in the refrigerator for easy cutting later or on the coutnertop.
  • When ready to cut, remove the fudge from the parchment paper. Trim off just enough of the edges to make straight smooth edges. (Or don't! This is only for looks.) Cut the remaining block in half one way and then the other way so you have four large squares. Each square can be cut in thirds one way and then thirds the other way so that each of the squares yields 9 pieces.
  • Store the fudge in an airtight container for up to two weeks. Or eat immediately.

Notes

  1. The type of peanut butter chip you use will affect the color, but should not greatly impact the taste. Bags range in size from 10 to 12 ounces. Because of the simplicity of this recipe, you should be fine using any of the sizes in that range.
  2. You want to double check that you bought sweetened condensed milk. It is sold right next to evaporated milk and the packaging often looks identical. If you use evaporated milk, this recipe will absolutely not work.

    SOUNDS GREAT…THANKS FOR SHARING, AND HAPPY THANKSGIVING!

    • Lisa Longley says

      Happy Thanksgiving Shirley!

  2. Ruth Zirtzman says

    Can you use this recipe without the peanut butter chips?
    Can you use only the condensed milk, peanut butter and vanilla?

    • Lisa Longley says

      Nope, it wouldn’t get solid with those ingredients.

  3. Sherri says

    Use the milk chocolate & peanut butter mixed bag of chips for a yummy peanut butter cup tasting fudge.

  4. Jennifer says

    Could u add marshmallow creme to it?

    • Lisa Longley says

      I haven’t tried that Jennifer, it is possible you need to make some adjustments if you do.

  5. Melissa says

    Can you use just peanut butter to make me a butter fudge with a sweetened condensed milk and vanilla

    • Lisa Longley says

      I’m sorry Melissa, that wouldn’t work in this recipe. You need the chips to help the whole recipe harden. I will have to work on one for you that is made with peanut butter.

  6. Amanda says

    5 stars
    I will definitely be trying this recipe! I was wondering if you had any thoughts on how to go about using the screwball Peanut Butter whiskey to make a boozy peanut butter fudge?

    • Lisa Longley says

      That sounds amazing! As you play around with it, be careful with the liquid to chip ratio or the fudge won’t set.

  7. Vicki says

    How do you make chocolate peanut butter fudge for lactose intolerant guests?

    • Lisa Longley says

      I’m so sorry, Vicki! At this point, I only have this recipe with the sweetened condensed milk.

  8. May Thompson Lehto says

    The different brands of sweetened condensed milk are not exactly the same and dont react the same. America’s Test Kitchen did a testing and I believe it was Bordens that came out on top and was most consistent.

    • Lisa Longley says

      I think you are right, May! I always use Eagle’s Brand but have noticed with some other brands that the thickness pools at the bottom of the can, which can be a real problem.

  9. Michele Vyas says

    Lisa I forgot to add the peanut butter will it still set? I did use condensed milk are you spraying the paper with vegetable spray or pouring it directly onto paper ?

    • Lisa Longley says

      I am not sure what will happen without the peanut butter, as this recipe was only tested with peanut butter. I don’t spray the parchment paper first.
