Recipe for Peanut Butter Fudge

This fudge recipe has become my go to fudge recipe due to how quickly the fudge sets, I typically do still wait a couple hours before slicing it, but it seems to be nearly complete and set after about an hour. Fudge in an hour, that’s amazing!! Also, unlike many other fudge recipes, this one does not require a ton of stirring or attention to the exact temperature of the mixture. I enjoy making this recipe with creamy peanut butter, it produces a smooth and creamy texture that is perfect. But sometimes it is fun to mix it up and use a crunchy peanut butter, who doesn’t love a little crunchy in their fudge? No matter how you choose to make this fudge the results you will achieve a nothing less than fudge perfection!

How to make Peanut Butter Fudge

Prep

Prepare an 8X8 (or 9X9) square pan with buttered foil. To do this, cut a piece of foil that is slightly larger than the pan and then spread softened butter on the foil with a spatula or by placing your hand in a plastic bag like a glove and using your fingers to spread the butter on the foil. Press the foil into the pan, butter side up. The foil should come at least most of the way up the sides.

Making the Fudge

Next, in a medium saucepan, bring the sugar and milk to a boil over medium heat, stirring occasionally. Boil for 2 1/2 minutes.

After the 2 1/2 minutes, remove the mixture from heat and add the peanut butter and vanilla extract, stirring until smooth.

Set and serve

Proceed to pour the fudge mixture into prepared pan and let set for about 1-2 hours in the refrigerator before slicing and serving.

To slice, just remove the entire foil from the pan and fold the edges down flat. It is so much easier to slice and serve this way than trying to do it while it is still in the pan!

Serve and enjoy!

Easy Peanut Butter Fudge Recipe FAQ

What kind of peanut butter is used in Peanut Butter Fudge?

I always make this recipe with regular creamy peanut butter and it works perfectly for achieving that smooth, fudgy texture. If you like a bit of crunch and texture, I think that crunchy peanut butter would work really well in this recipe too. Use a regular peanut butter like Jif or Skippy for best results – I have found that more natural peanut butters (the ones where the oil is separated out) usually don’t work as well in baking, most likely because they tend to be a little bit runnier.

Why is my peanut butter fudge not setting?

If your fudge isn’t setting, double check that you added the full 2 cups of sugar to the pan. Make sure you brought the fudge to a full boil before starting your 2:30 timer.

Why is my peanut butter fudge dry and crumbly?

Make sure you didn’t overcook the fudge to avoid it getting dry. The best way to avoid this is by setting a timer when you’re cooking the milk and sugar.

What ingredient makes fudge hard?

Milk and sugar boil together to make a type of candy, which, when combined with the peanut butter, cool and harden to make the fudge.

What causes peanut butter fudge to be grainy?

You can stir the sugar and milk while they are cooking to make sure all the sugar granules dissolve and avoid grainy fudge.

Why is my peanut butter fudge oily?

Oily fudge happens most often as a result of the type of peanut butter used to make it. Natural peanut butters tend to be more separated, resulting in oily fudge. I recommend using basic Jif or Skippy to make this fudge recipe.

Storing Easy Peanut Butter Fudge

Does homemade peanut butter fudge need to be refrigerated?

Peanut Butter fudge should NOT be refrigerated as it tends to dry out the fudge.

Can you freeze fudge?

Yes! Freezing fudge is easy. Just double wrap it in plastic wrap or parchment paper, then store it in an airtight container. Will stay fresh for 3 months. Thaw and cut into squares to serve.

Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.

How do you make fudge thicker? ›

Should fudge be covered while setting? ›

depending on the batch size, speed of the mixer and temperature in your kitchen. Pour the fudge into the baking pan/mold. I let it set for just a minute or two and then cover it with another layer of plastic wrap to touch so it doesn't form a skin while setting.
