Why This Fudge is Best

Why do we suddenly stop eating peanut butter and jelly sandwiches when we grow up? They’re delicious, easy and perfect for a lunch box. I love mine heavy on the peanut butter with just enough jelly or jam to add a sweet, fruity flavor.

  • This PB&J Fudge has an irresistible blend of sweet and salty flavors.
  • Crunchy peanuts add satisfying texture to the soft, smooth fudge.
  • NO candy thermometer needed.
  • It’s an easy no-bake recipe for any occasion.
  • Adults love this peanut butter and jelly treat as much as the kids!

Ingredient Notes

  • Peanut butter – We used a combination of creamy AND crunchy peanut butter for this fudge. If you prefer a fudge without chunks of peanuts, use all creamy instead.
  • Marshmallow cream – This spreadable marshmallow product is the secret to soft fudge without needing a candy thermometer. Our homemade marshmallow fluff can work great here too.
  • White chocolate morsels – Or use a white chocolate bar broken into small pieces!
  • Strawberry preserves – Feel free to substitute this for other fruit preserves you like in your PB&Js. Raspberry and grape are both popular choices that would taste wonderful in peanut butter fudge. Our homemade strawberry jam would be perfect!

Tips and Tricks

Making impressive fudge isn’t difficult. But to get great results every time, here are a few key details to pay close attention to.

First, make sure to let your mixture of butter, heavy cream and sugar come to a rolling boil on the stove. Once it’s boiling, stir it constantly as it boils for a full 4 minutes. This step ensures your fudge will set up to the right consistency.

After the boiling step, pour the mixture over the white chocolate chips and marshmallow cream immediately. The heat helps melt the chocolate as you combine all the ingredients together.

To add preserves to the peanut butter fudge, pour half of the fudge mixture into your baking pan. Spread preserves on top with the flat side of knife before adding the remaining fudge on top.

You’ll also want to swirl the top layer so you can see the color of the strawberry jam peeking through.

Once the fudge has set, store it in the refrigerator in an airtight container. It keeps well for up to 2 weeks. That is, if you can resist diving head first into the whole batch right away!

Recipe FAQs

What kind of peanut butter is best?

You can use any kind of peanut butter in today’s recipe. I tested the recipe with shelf stable peanut butter which contains added sugars and stabilizers.
If you use natural peanut butter, your fudge will be less sweet and may be more crumbly. That’s why we general opt not to use it in recipes like this one.

If I love crunchy peanut butter can I make this fudge with all crunchy peanut butter instead of cream?

I don’t recommend using only crunchy peanut butter for fudge. All the peanut chunks (while delicious) will make the fudge crumbly. That’s why we use mostly creamy peanut butter with just enough crunchy peanut butter to give the fudge some texture variety.

Can I freeze this fudge?

Yes, you can. Store it well wrapped and sealed in a freezer safe container. Thaw frozen fudge in the refrigerator overnight before eating.

Comments & Reviews

  1. Tell your hubby there’s another who likes the peanut butter and no jelly. I’ve been here almost six decades and have never eaten a peanut butter and jelly sandwich. It’s either a peanut butter sandwich or a jelly sandwich. I’m not crazy about mixing my foods.

  2. Thin peanut butter, thick jelly!!! That’s the winner! Listen to me, I know these things. 😉 

    I am soooo in love with this fudge. I mean, it’s PB & J in FUDGE-form. Freakin’ amazing! 

  3. I think this idea for fudge is genius!!! Love it 🙂
    ps. I´m thick peanut butter, medium jelly 🙂

  4. I am all about option number 3 as well but i can’t just can’t do crunchy! Looks amazing!

  5. I think I’m usually in the thin/thin (and crunchy!) camp, but I like to mix it up 😉 I’m also firmly in this fudge’s camp..because YUM!

  6. My PBJ sandwiches are few and far between these days but when I do have one, I LOVE them!

  7. Sometimes you can’t beat a classic like PB&J! Love that you turned this into fudge!

  8. I love my peanut butter…sometimes I don’t even bother with the jelly, that’s how much I enjoy it.  These fudge bites sound like such a treat….I love  this idea! They wouldn’t last long in my house! xo, Catherine

  9. I’m thick on the PB, thin on the jelly. But you bring up such an important point, Aimee. Every person should make his or her own PB & J. It’s a very personal thing! 🙂
    But you can make all my PB & J fudge for me. I think you will make everyone happy with this one!
