Peanut Butter and Jelly Bars are a fun spin on the classic PB&J sandwich. You will be amazed at how easy these bars are to make and how delicious they taste.

Peanut butter and jelly bars

Peanut butter desserts are loved by everyone. Soft peanut butter cookies, peanut butter pie, and chocolate peanut butter cheesecake are often my go-to recipes when I’m craving peanut butter. That is until I made these bars!

These peanut butter and jelly bars are similar to fudge-filled peanut butter cookie bars. There’s a chewy peanut butter crust layer, jelly layer, and crunchy topping. This recipe is for those of you who prefer fruity desserts over chocolate.

The filling is nothing more than jelly or jam from a jar. Choose any flavor you want. It doesn’t have to be grape. Maybe you’re a strawberry lover. Or apricot lover. If you make your own jellies and jams, you can use that too!

You need just a few ingredients to make these bars and I’m fairly certain you already have them on hand. Or most of them at least.

There are no special tricks or long periods of wait time with these bars. Mix the ingredients, layer them in an 8×8 pan, and bake. Too simple.

Use Room Temperature Ingredients

Make sure your ingredients are at room temperature so everything mixes together easily. This rule applies to all baking unless the directions specifically call for cold ingredients.

Main Ingredients

Crunchy peanut butter – I used crunchy peanut butter because I like the texture but feel free to use creamy peanut butter if you’d like.

Jelly – Grape jelly is classic for a pb & j but other flavors work well. Give strawberry or apricot a try!

How to make peanut butter and jelly bars

Step 1: Combine the wet ingredients

Cream the peanut butter, butter, and brown sugar together then mix in the egg and vanilla.

Step 2: Add the dry ingredients

Combine flour, salt, and baking powder then fold it into the wet ingredients just until combined. Take care not to overmix or the bars will come out tough.

Step 3: Layer the batter with jelly and bake

Press ⅔ of the batter into the bottom of an 8-inch square baking pan. Spread jelly evenly over the batter. Crumble the remaining batter over the jelly and top with chopped peanuts.

Tips for Success

Use room temperature ingredients. This will make mixing everything together so much easier.
Use your favorite jelly!
Crunchy peanut butter adds a lovely texture contrast to the base of the bars but you don’t have to use it. Creamy peanut butter works just as well in this recipe.

As a pastry chef of more years that I can count its rare that I bake outside of my recipe file, but this one is a keeper. Strawberry preserves made them perfect.

Why is there unsalted butter used, then salt added later in the recipe, and then adding salted peanuts on top. Doesnt figure to me, only to much salt is not good. And probably salt in the peanut butter.

1. You can’t control how much salt is in salted butter. This is why you use unsalted butter. You can control how much salt to add to the recipe without making it too salty.

2. Normal to use unsalted butter when baking. Salted butter is a big no, assembled stated you can’t control the salt content if used.
