These Peanut Butter and Jelly Bars turn a classic lunchtime snack into a delicious, gooey cookie bar! Easy gooey bars start with a cake mix and are full of peanut butter and jam flavor – you’re going to love them.
Peanut Butter and Jelly Cookie Bars
These cookie bars use a cake mix as base, and the outer layers are primarily peanut butter, while the middle layer brings in the sweet jelly. You can use jam or jelly all depending on whatever you prefer!
I Love gooey bars so much because they are so versatile and can be done in so many different ways. Just like this fun recipe. When my daughter was little she loved them, therefore they are perfect for anyone!
Ingredients Needed
- Yellow cake mix: You really can use any flavor or brand, but I love using yellow cake mix.
- Vegetable oil: Helps moisten the dough and keep it soft.
- Peanut butter: Make sure to use a no-stir (not natural) peanut butter
- Jam or Jelly: Use your favorite flavor.
How to make PB&J Bars
- Preheat oven to 350°F. Line a 9×9” pan with foil and spray with cooking spray.
- With a hand mixer or electric mixer, beat eggs, cake mix, oil, and peanut butter until mixture is crumbly. Press about 1/2 of the mixture into prepared pan.
- Spread jam over the crust. Scoop bits of remaining batter and flatten between your hands and place on top the jam. It won’t fully coat.
- Bake for 25-28 minutes, until top just starts to get golden brown. Cool completely before slicing into bars.
Expert Tips
- I would recommend using seedless jam or jelly to avoid an extra texture that is not wanted in these bars.
- You can add peanut butter chips or white chocolate chips into this recipe if you would like too!
- You know they’re done when they become golden brown around the edges and are no longer glossy.

In Minnesota it’s a law that school can’t start before Labor Day…so I find it so weird reading about everyone going back to school already! These bars look amazing. I love PB&J and I can not believe you were in your 20’s before you tried jelly!!
