Peanut Butter Chocolate Chip Cookie Bars

August 9, 2011 | 50 Comments | Email | Print

I am dumbfounded as to how these cookie bars do not yet have their own little cozy corner of this site. After the chunky pecan pie bars, these cookie bars were the second baked good that I made over and over and over again in high school and beyond. I came across a recipe for chocolate chip cookie bars at one point, and then decided that they needed peanut butter and some peanut butter chips for good measure. Like most things in the kitchen, peanut butter turns regular chocolate chip cookie bars into an amazing concoction that are completely addicting.

I made these a lot in high school, and once college rolled around I went to a school in the same city that I lived, while two of my best friends went off to a school a couple of hours away. While I lived on campus at school, I was only 25 minutes or so away from home, so I made it home more often than my friends did. I took the opportunity to bake these up every time I was home, and then I would package them up and send them off to my friends. I still remember standing in the kitchen and packing them up in shoe boxes to mail off.

They always made my friends smile – they got a taste of home, and I got the satisfaction of baking and showing my friends I cared. I highly recommend baking these and sharing them with someone you love!

Peanut Butter Chocolate Chip Cookie Bars

Yield: 32 bars

Prep Time: 10 minutes | Bake Time: 16 to 20 minutes

1½ cups all-purpose flour
½ teaspoon baking soda
¼ teaspoon salt
¾ cup light brown sugar
¾ cup creamy peanut butter
½ cup unsalted butter, at room temperature
½ cup granulated sugar
1 egg
1 teaspoon vanilla extract
1 cup semisweet chocolate chips
1 cup peanut butter chips

1. Preheat oven to 350 degrees F. Grease a 9×13-inch baking pan; set aside.

2. In a small bowl whisk together the flour, baking soda and salt; set aside.

3. In the bowl of an electric mixer, cream together the brown sugar, peanut butter, butter and granulated sugar on medium speed until creamy and light. Add the egg and vanilla extract and mix until combined. Reduce speed to low and add the dry ingredients, mixing only until the flour is just incorporated. Using a rubber spatula, mix in the chocolate chips and peanut butter chips.

4. Turn out the mixture into the prepared pan and press into an even layer. Bake for 16 to 20 minutes, or until the center is set. Cool completely in the pan on a wire rack. Cut into bars and store at room temperature in an airtight container.

Wow these look amazing. I wish I could eat peanut butter, but I’m allergic to peanuts.

You were very good to your friends. =) And popular with them, too, I’m sure. Come to think of it, my popularity in every new office has always increased exponentially when I started baking people happy. That, or a candy jar on the desk, is a great way to break the ice!

Can you ever go wrong when you add peanut butter? Great recipe! It would bring a smile to my face too :)

I’m not much of a fan of peanut butter, but these look amazing!

Your blog is amazing. I am a huge oat fan and love the combo of oats, peanut butter and chocolate chips. Do you think I could change the recipe around so that the addition of oats would be complementary? If I reduced the flour and added some oats do you think this would turn out? Any suggestions would help. Thanks!

Michelle August 10, 2011 at 2:37 pm

Hi Gretta, Yes I don’t see any reason why that wouldn’t work.

After looking at these scrumptious bars I’m wishing that I was one of your very fortunate friends back in your schools days. How I would have jumped for joy at receiving a shoe box full of these in the mail from you.

Oh my these look so delicious. Knocked another one out of the park. Love them. and your friends are so lucky.

These look incredible, much like everything else you make. I can’t wait until my kitchen is done and my mixer is back in business! I’m a PB and chocolate addict as well and LOVE your use of the two together. I want to try your cream cheese/brownie recipe BUT use PB cream cheese. I figure chocolate+pb+cream cheese can’t be bad…

MIchelle, these were amazing. I am also a notorious peanut butter + chocolate fanatic, and made these tonight (added an egg, an extra huge glob of peanut butter, and butterscotch chips to the mix). I ate half the pan. (My bf, who doesn’t eat baked goods, was incredulous.) Keep ‘em coming!

I agree – peanut butter and chocolate go hand in hand, so I have no doubt that these cookie bars are downright excellent =)

These bars are so delicious! I made them today for lunch & our guests couldn’t stop eating them. They are rich & totally scrumptious. Thanks so much for this wonderful recipe. Just wonderful.

Okay, come on – just made this recipe…. “Cool completely in the pan on a wire rack.” – Yeah right, you think we could wait that long!!!! ;) Sure it comes out of the pan better once it’s cool, but it tastes so yummy hot! No willpower in this house! ;)

Really yummy. I received very strict instructions to never make these again! The sandy texture, slight salt hit, and sweetness of the chocolate were wonderful together. Going into the Christmas plates this year.

Reply

MsK September 29, 2011 at 4:02 pm

These are great!! I made them last night. I did tweak the recipe a bit. I cut down the actual amount of peanut butter and substituted white chocolate chips for the peanut butter chips. Still great. They were a hit with my nieces and nephews. None of them are big peanut butter fans. So this is why I tweaked the recipe. Either way, it was a success. Thanks!!

Just made these and they are perfect. So chewy and packed with peanut butter flavor! I skipped the peanut butter chips and just used chocolate chips but it was still fantastic. Thanks!

How do I adjust the time/heat if baked in a glass 13×9 dish? My friend borrowed my pan and I want to make these tonight!

Reply

Michelle January 31, 2012 at 11:11 am

Hi Michelle, You don’t need to adjust anything – this recipes calls for a 9×13-inch baking dish.

Michelle S. January 31, 2012 at 2:23 pm

Thanks! I just made these with whole wheat flour, Splenda, reduced fat PB, and crushed dry-roasted peanuts (instead of the PB chips). They came out absolutely perfect and are sooo delicious!!

This recipe is amazing! I made them 2 nights ago and they are already gone. I’m going to need to make 2 batches for the Superbowl!
