Peanut Butter and Jelly Bars

There is something so comforting about peanut butter and jelly. The classic peanut butter and jelly sandwich is a combination of three foods that have been around for a long time: sliced bread, peanut butter, and jelly. These peanut butter and jelly bars give you the same flavors as the classic sandwich in a bar form.

PB & J Bars Ingredients

Peanut Butter: I used both creamy and crunchy peanut butter in this recipe. You could definitely stick to using all of one or the other per your preference.

Preserves: Strawberry preserves are spread in between the layers of peanut butter bar batter. You could use jelly or jam. And, of course, use your favorite flavor!

Peanuts: Chopped peanuts top the bars for a little extra crunch in every bite. You could leave those off if there is enough nuttiness in the bars for you already.

Process Steps for Making Peanut Butter and Jelly Bars

How to Store Peanut Butter and Jelly Bars

Store the bars in an airtight container at room temperature for up to 3 days. They will last a couple of days longer if stored in the refrigerator.

  1. If I understand the recipe correctly, once you assemble the bars, the pan is covered with foil and baked until done. Have I got it?

  2. These are amazing! I’ve made them for two different tailgates and they were a huge hit each time. Thank you!

  3. I need help Amanda!! I followed your recipe to the letter, but it seems after I cooled them they don’t seem completely done when I cut them…..what am I doing wrong? Thank you!!

  4. Sorry, forgot to add…….I used raspberry jam instead of the strawberry you have listed, but do not think that should make a difference. Would it be the jam that makes it appear not done in the middle? Thanks again!

  5. These were amazing! I do a lot of baking, and try lots of new recipes. Very few impress me. This one is a keeper! Delicious! Thank you for sharing.
