My mom and grandma always worked feverishly in their kitchens around the holidays. They’d whip up batches of their famous peanut brittle that required precise temperatures and even spatulas or it would flop. 

Fortunately, Peanut Butter Fudge is foolproof! It has the creamiest texture and can’t-keep-my-hands-off-it quality that keeps you coming back for more!

I love all fudge at the holidays, including this classic chocolate fudge and vanilla fudge, but none can stack up to the sweet and salty creaminess of this fudge!

Two ingredients make this fudge recipe stand above the rest – milk and powdered sugar. It gives it the creamiest, dreamiest crowd-pleasing texture!

This Peanut Butter Fudge recipe is incredibly quick and easy to make. It takes just 10 minutes, six staple ingredients and a little patience to solidify before you enjoy. That’s the most difficult part for me, waiting!

It’s so good that I recommend you have a share plan in mind. It’s seriously addictive.

Even better, this fudge doesn’t require any special tools or candy thermometers. It is made in a baking dish like the same square pan you use to make brownies. Honestly, it’s so SIMPLE! It’s a great no bake dessert!

Ingredients and Substitutions

It’s made with staple ingredients you likely already have in your pantry!

  • Butter – salted or unsalted, your preference.
  • Brown Sugar – this ingredient offers beautiful color and a hint of molasses flavor.
  • Whole Milk – or half and half, one reader even mentioned using skim, though I haven’t tested it.
  • Peanut Butter – use creamy, but avoid using natural. It has an entirely different consistency that doesn’t play well with fudge and allow it to solidify.
  • Vanilla – I like to use Homemade Vanilla Extract, but any vanilla will do!
  • Powdered Sugar – also known as confectioner’s sugar, this maintains that smooth, creamy consistency that’s synonymous with peanut butter fudge.

Variations

  • Add nuts
  • Swirl it into chocolate fudge
  • Add marshmallows
  • Add chocolate chips
  • Cover in melted chocolate to make Buckeye Fudge – seriously, it tastes exactly like Buckeyes!
  • Substitute coconut milk for the Whole Milk for a different flavor profile and less dairy.

Microwave Directions

If you really want to, you can even make Peanut Butter Fudge in the microwave! It’s a great way for kids to help in the kitchen.

  1. Simply combine butter and peanut butter in a microwavable bowl covered with a paper towel to prevent spatter.
  2. Microwave on high for 2 minutes.
  3. Stir and continue to microwave for 2 more minutes.
  4. Add the milk, vanilla and powdered sugar to the peanut butter mixture and stir until batter is smooth.
  5. Pour into greased pan and smooth with parchment paper.

Tips

  • Resist the temptation to stir the ingredients in your pan.
  • A reviewer notes that she was able to substitute the butter with coconut oil, but has had best results with butter.
  • Use a cookie cutter to create fun shapes!
  • You can use any pan you have – 9″, multiple loaf pans, etc. Just keep in mind it will change the thickness of the fudge.
  • Did you know that you can also make fudge in a slow cooker? Get the easy vanilla fudge recipe here.

Frequently Asked Questions

Why won’t my peanut butter fudge harden?

Often this means that your ingredients need to be cooked down a little longer, or to a higher temperature. If this happens, try reheating your peanut butter fudge by adding a little more milk and bringing it back to a slow boil.

Why is my peanut butter fudge oily on top?

If your fudge shows oil on the top, it could actually be that you are overcooking or simply over-stirring. Use a gentle hand with very minimal stirring and allow the ingredients to come to a slow boil.

How to Store

  • Room Temperature – As always, fudge is best enjoyed fresh, but you can store it at room temperature in an airtight container to keep this fudge fresh for up to two weeks.
  • Refrigerater – It can also be refrigerated in an airtight container. Bring to room temperature to enjoy.
  • Freezer – You can freeze Peanut Butter Fudge wrapped in wax paper and sealed in a ziplock bag inside an airtight container for up to 6 months. This will eliminate any risk of absorbing odor from your freezer.

To thaw, simply remove the fudge from your freezer and bring it to room temperature before opening.

  1. This! This PB fudge was ah-mazing! I made four batches of it for a work function…actually National PB Fudge Day – it’s a real thing! Nov 20, 2017. They love it! I finally printed the recipe and set it next to the trays of fudge. Thank you for posting some good sweet, love!

    1. Oh my gosh, this brings me so much joy! How did I miss the best day of the year? I’ll be whipping up several batches over the holidays. I may even share a little, too! Hope you enjoy the holiday season!

  2. The first time I made it, it was perfect. 2nd and 3rd time it has a layer of melted butter on it when I spread it out. What am I doing wrong?

    1. Oh no! Are you rushing it? Try beating it longer next time. Also, don’t forget that you can’t touch it the first couple minutes, it’s important in fudge making.

  3. Okay. This recipe did not turn out well for me at all. I went to mix the powdered sugar in with the rest of the mixture and it all turned very dry and crumbly. Not smooth at all. Some feedback would be appreciated.

    1. I’ll note that in my recipe – you just didn’t take it quite far enough. As the peanut butter warms, it becomes creamy. I hope you had a beautiful weekend!
