2 Ingredient Peanut Butter Fudge Recipe

This delicious peanut butter fudge recipe is easy to fall in love with. It's made with only 2 ingredients and results in the smoothest and creamiest peanut butter fudge ever! Plus, it only takes 5 minutes to prepare, then it just has to set in the fridge after that. 

Ingredients You'll Need

This is the easiest peanut butter fudge recipe you'll find, and the ingredient list just goes to show it.

As you already know, just two easily accessible ingredients are all that's required to make it. And, honestly, you probably already have them in your pantry already!

Anyway, here's what you'll need to make it:

• 8 oz. Creamy Peanut Butter 
• 8 oz. Vanilla Frosting

Yup, that's it! 

I will tell you occasionally I top this peanut butter fudge with powdered sugar, but that's totally optional.

Now, when it comes to peanut butter, I prefer using a smooth peanut butter like Jif, but natural peanut butter will work well too. As for the vanilla frosting, any store-bought vanilla frosting works great. I've used a bunch of different ones to make this recipe with and never had any issues.

By the way, if you like the idea of this recipe and love chocolate fudge, you have to try this chocolate peanut butter fudge next. It's another creamy fudge made with peanut butter and chocolate frosting instead of vanilla. 

Ways To Change Up This Peanut Butter Fudge

This fudge recipe is easy to switch up and change the flavor profile of.

Here are some of my favorite ways to make this peanut butter fudge recipe a little differently each time:

• Peanut butter explosion: Add Reese's cups, Reese's pieces, and peanut butter chips on top of the fudge before refrigerating.
• Peanut butter chocolate chip fudge: Top the fudge with chocolate chips before refrigerating.
• Marshmallow cream fudge: Once your peanut butter fudge mixture has been poured into your prepared pan, add spoonfuls of marshmallow cream or fluff on top and swirl it into the fudge with a toothpick.
• Peanut butter cheesecake fudge: Swap half of the vanilla frosting with cream cheese.
• Oreo peanut butter fudge: Add crushed Oreos to the fudge mixture and mix them in.

How To Make Peanut Butter Fudge

As I've mentioned a few times, this is a super easy peanut butter fudge recipe. I mean, how can you beat needing only a couple of ingredients and having to follow less than a handful of steps to make it?

Not to mention, you don't even need to use a stovetop to make it, and it literally comes together in under 5 minutes - it does need a little time to set though.

Anyway, let's not waste any more time and get to it!

Step 1: Combine The Ingredients

First, you're going to add the jar of creamy peanut butter and vanilla frosting to a microwave-safe bowl.

Then microwave the peanut butter and frosting in two, 1-minute intervals. Stir constantly between each interval until the peanut butter and frosting are thoroughly combined.

Step 2: Pour The Mixture into a Pan

Next, line a loaf pan or square pan with parchment paper. Any size actually works really great, it will just change the thickness of the fudge. But if you don't know what to use, a 9x9 or 8x8 works really well.

Now transfer the peanut butter fudge mixture to the prepared pan and smooth out the top of it with a rubber spatula or the back of a spoon. 

Step 3: Chill The Fudge

Once the fudge is in the pan, transfer it to the fridge and let it chill for about an hour or until the fudge sets. 

Step 4: Slice & Serve

When an hour is up, or the peanut butter fudge has fully set, you can let it thaw for a few minutes at room temperature.

Then, slice it into about 8 squares, serve, and enjoy!

How To Store The Fudge

As I just mentioned, this peanut butter fudge recipe will make only about 8 squares of fudge. So if you make the recipe as is there's a good chance you won't end up with much leftover fudge. That's why I always double or triple the recipe when I make it - I like to have a bunch of it on hand for the days/weeks after I make it.

Anyway, if you end up with some leftovers you'll want to transfer them to an airtight container and keep them at room temperature for up to a week or in your refrigerator for 2-3 weeks.

Alternatively, if you want to store your fudge for even longer, you can freeze it. Again, just store it in an airtight container with sheets of parchment paper between the fudge layers and it will stay good for up to 6 months.

Wrapping Things Up

Well, that's how to make peanut butter fudge with 2 ingredients! This is hands down one of the best fudge recipes you'll ever try - and that's especially true if you love peanut butter.

Whether it be for the holiday season, or when you just want to satisfy that sweet tooth craving, this is the recipe for you. And it's just the perfect no-bake dessert that is sure to please adults and kids alike!
