Peanut Butter Chocolate Chip Bars

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.

Main Ingredients Needed

For these Peanut Butter Chocolate Chip Bars, 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 + Granulated Sugar – creamed with the butter, these are both used for sweetening and flavor.
  • Egg + 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.
  • Milk Chocolate Chips + Semi Sweet Chocolate Chips – I used both for flavor and to evenly distribute the chocolate!

How to Make Peanut Butter Chocolate Chip Bars

For full details on how to make Peanut Butter Chocolate Chip Bars, see the recipe card down below 🙂

Step 1: Preheat + Prep

Preheat oven to 350 degrees. Line glass 9×13 dish with parchment paper and set aside.

Step 2: Make the Dough

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. Add in egg, egg yolk, and vanilla. Mix until lighter in color. 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 dough.

Step 3: Add Chocolate Chips + Press Dough Into Pan

Hand-stir the chocolate chips into the batter and press into the prepared pan.

Step 4: Bake + Cool

Bake 15-18 minutes or until the center is mostly cooked. 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 bars cut and hold their shape much better after cooling completely.

Peanut Butter Chocolate Chip Bars FAQs

How would I double this recipe?

You can easily double this recipe by using another 9×13 pan! More bars mean more for sharing.

Do I have to use semi-sweet chocolate chips?

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

Can I sub out the butter for oil?

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

How can I add even more peanut butter into these bars?

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.

    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.

    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.

  8. 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.

  9. 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! 🙂

    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

    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.

    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! ♥️

  14. Jill Boyce

    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.

  15. 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.

  16. Natalie Woll

    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! 😁
