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 my fudge-filled peanut butter cookie bars from my eCookbook. 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 trick 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 to make theses pb & j bars

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 for peanut butter and jelly bars

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 – Gape 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 2/3 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.

Bake the bars in a 350°F oven for 30-35 minutes.

  • 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.

Instructions

  1. Preheat the oven to 350ºF degrees. Line an 8x8-inch baking pan with foil, leaving a 1-inch overhang. Spray the foil lightly with cooking spray. Set aside.

  2. In a large mixing bowl beat together the peanut butter, sugar, and butter until smooth. Add the egg, beat until well blended. Beat in the vanilla.

  3. In a separate bowl, combine the flour, salt, and baking powder. Stir with a whisk. Add the flour mixture to the peanut butter mixture, stir just until blended.

  4. Press 2/3 of the batter into the bottom of the prepared pan. Spread the jelly evenly over the batter. Crumble the remaining batter evenly over the jam and sprinkle with peanuts.

  5. Bake for 30-35 minutes until bars are golden brown on top. Allow the bars to cool completely in the pan on a wire rack. Lift the bars out of the pan by the foil overhang. Cut into squares.

Make ahead tip

  1. Bars can be made 3 days in advance. Store in an airtight container at room temperature.
