Chocolate Chip Peanut Butter Bars

50 · Feb 4, 2018

Peanut butter and two kinds of chocolate chips make these moist and delicious bars irresistible. Made in one bowl and baked to perfection, this dessert will have you swooning!

A couple of days into February and already I’m jumping on the dessert train! January was fun with the skinny recipes I’ve shared (and I still have a few more coming!) but I needed a sweet treat BAD and decided to throw something amazing together late one night with what I had on hand.

You know what I love better than cookies? Cookie 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! I love cookies as much as the next person, but when I have cute little ticking time bombs asleep in their beds with a sweet tooth to fill and work to finish between the hours of 7 and 11pm, I have a tendency to rush these sorts of things.

MY LATEST VIDEOS

But besides them being really simple to make and filling my sweet tooth for the majority of this past week, they also taste amazing and are the perfect blend of chocolate and peanut butter. 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.

And if you think you wouldn’t want to try this recipe today, give my simple sugar cookie bars, my Cookies n’ Cream Brownie Bars or my Actually Perfect Chocolate Chip Cookies (which is the recipe I based this recipe off of).

Below are a few photos of the process, and of course the the printable version of the recipe for your printing pleasure.

Have a great weekend, friends! xo

    Ummm….why? Why must you post these things when I am watching calories? Especially when I have all ingredients on hand. And especially when it’s that time of month. These look amazing. I will let you know if I cave. 🙂

    I’m single and I don’t want to or need to eat a whole pan

    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

    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.
