Do you know what I love better than peanut butter cookies? Peanut Butter Chocolate Chip Bars. You don’t have to spend your evening scooping dough and all you have to do is press them into a pan and bake! But besides them being really simple to make they also taste amazing and are the perfect blend of chocolate and peanut butter.

Peanut Butter Chocolate Chip Bars

For this cookie bar recipe, you’re going to want to gather up all of the regular ingredients you’d use for normal cookies. Plus a couple of special mix-ins. Here’s what you’ll need:

  • Butter – delicious fat to start these cookies off right.
  • Smooth Peanut Butter – if you like that extra crunch, use crunchy peanut butter.
  • Brown Sugar and Granulated Sugar – creamed with the butter, these are both used for sweetening and flavor.
  • Egg and Egg Yolks – these are both used for the structure and texture of the cookie bars.
  • Vanilla – for flavor.
  • All-Purpose Flour – to fill out the bars.
  • Baking Soda – the leavening agent.
  • Salt – to balance out all the sweetness.
  • Walnuts – chopped. You could also sub these out for a nut that you like.
  • Mini Chocolate Chips – I used semi-sweet mini chocolate chips.
  • Chocolate Chips – I used milk chocolate chips.

How to Make Peanut Butter Chocolate Chip Bars

  1. Preheat oven to 350 degrees. Line glass 9×13 dish with parchment paper and set aside.
  2. Place butter and peanut butter into a large bowl and melt together in the microwave. Stir in brown sugar and granulated sugar until well combined.
  3. Add in egg, egg yolk and vanilla. Mix until lighter in color.
  4. Add in the flour, baking soda, and salt. Scrape the sides of the bowl and the bottom really well to ensure a smooth, well-stirred batter.
  5. Hand-stir the chocolate chips into the batter and press into prepared pan.
  6. Bake 15-18 minutes or until the center is mostly cooked.
  7. Cool 15 minutes before cutting into bars and serving. (Of course, you’re going to want to dig right in once they get pulled from the oven, but let this be your friendly reminder that these chocolate chip peanut butter bars cut and hold their shape much better after cooling completely.)

Tips and Tricks

Double. You can easily double this recipe by using another 9×13 pan! More Peanut Butter Chocolate Chip Bars means more for sharing.

Chocolate Chips. Consider using different kinds of chocolate chips for this recipe. Dark chocolate, or even peanut butter chips!

Oil. I wouldn’t recommend using oil instead of butter for these cookie bars, because it throws off the texture.

Peanut Butter. A fun way to elevate these bars, especially if you love peanut butter, is to swirl some throughout the dough. The results are spots of warm peanut butter mingling around melted chocolate chips.

    These sound heavenly! Nothing much better than chocolate and peanut butter! And bars are WAY better to make than cookies…cookies take way too much time! 😁

  4. Leighann

    I really want to make these and eat them all! Peanut butter and chocolate is my favorite combination . I am saving this recipe for our family beach trip this year.

    You always have mouth watering deserts that make it hard on a girl trying to be good. Oh well there’s always next week to give up sugar.

    Help! These are the best bars ever! I made Them last week and wanted to post a photo for you. They were gone soooo fast! No chance of taking a photo 🤳🏻. My husband said don’t ever make these again. I thinh He ate half of the pan himself. We all had noooo self control – will make them again and again. Preferably when we have guests to share with! ♥️

    Cannot wait to try these. This is a plan for this weekend. We LOVE peanut butter-can’t always have it because of school rules, so these are a nice treat for home.

  9. Gail Kienle

    We have a group that gets together most Sat. nights. We all bring something to contribute to the meal. I am the only one who likes to bake so I frequently get dessert. This sounds amazing and the guys always want something that goes with ice cream. Thanks Lauren. Love that little guy, Eddy. He may be frustrating but he sure is a cutie. Gail

  10. Bethany Croney

    These look so yummy and divine! Plus I have everything on hand to make them…hmm, maybe a good Valentine’s potluck dish? I’m thinking tonight I’ll be making chocolate chip peanut butter bars while watching you dip strawberries into chocolate! 🙂

  11. Amanda

    These look so good! I frequently bake for my coworkers and bars are one of my favorite things to bring them. I’m going to add this to my arsenal of recipes to bake and share.

    Yummy! I have made these twice. Second time I did a 1 and 1/2 size recipe batch. I have three (8″?) heart shaped pans and it worked perfect. Put them on a large pretty red plate, drizzled white frosting and sprinkled with red sugar and they were to die for! Took one to son at college, one to best friend and one to neighbor for helping us with the horrible 14″ of snow!!
    thank you for sharing.

  13. De Oda

    Love peanut butter and chocolate…and who doesn’t love bar cookies. Once my daughter is back home from college, I’ll make these. She and I love baking and eating it all by ourselves…lol.

  14. Stephanie K.

  15. Karen

    OMG Lauren! You kill me… I cannot wait to try these!! I would have made the the day you posted them but… diet. Ugh. They totally look worth breaking a diet for!! The temptation is killing me.

  16. Laura

    These have been on my list to try! Added the recipe slip to my jar… hoping to draw that one soon (maybe I’ll rig the drawing 😉 !

    Saw the prep time of ten minutes and knew it was a winner. With one year old twins and a three year old time is important!! Thanks for a quick and delicious recipe!!

  18. Kelster

    These look so easy to pull together and I already have all these ingredients on hand. I need a baking project tomorrow and this might be it.
