We love these delicious peanut butter chocolate chip bars! This is one of our favorite cookie recipes and has been for almost 35-38 years. Next to our “Chunky Blond Brownies” recipe I have made these delicious bars more than any other recipe–probably hundreds of times. No kidding! It’s SO quick and easy to throw together. I can have a pan of this bar whipped up and ready to put in the oven in about 5-7 minutes.
We’ve made this recipe almost every year for 35 years for our Christmas cookie extravaganza where we bake anywhere from 2,500 to 5,000 cookies, brownies or bars for family, friends, co-workers, neighbors, and folks at our church. Everybody loves this recipe. It’s especially kid-friendly. And the taste–oh, so A-M-A-Z-I-N-G!!!
I first got this recipe off the back of a Nestle’s chocolate chip package around 1975–even before I got married. I remember trying it the first time when I was 18 or 19 and I didn’t understand what inserting a knife into the dough to marbleize meant! I just stuck the knife into the bottom of the pan in several spots. (Talk about culinarily-challenged!) It was a couple of years later when I finally figured out marbleizing meant to swirl the knife into the batter and mix the chocolate with the peanut butter batter. I’m so glad I didn’t throw the recipe out because it didn’t work for me the first time! Through the years I have pretty much followed the recipe as written without changes–one of the few recipes I have ever done that with!
This is a photo of these delicious peanut butter and chocolate swirl bars.
Don’t these look wonderful?
This is a little bit closer so you can see the texture.
Here’s a picture of an individual brownie. Yum, yum! We love these fantastic bars.
Here’s what I did.
Soften butter and put in a mixing bowl. I am making a double batch here so ingredients will be doubled.
Add crunchy peanut butter (not creamy — no exceptions!)
Add brown sugar.
Add white sugar.
Add baking powder and Kosher salt.
Add UNBLEACHED all-purpose flour. Bleached flour toughens cakes and cookies.
Stir all ingredients together. This is what the peanut butter batter dough looks like.
Spray 9×13″ baking pan or dish with cooking spray. I have had this pan since before I made this recipe for the first time! You can tell by looking at it that this pan has seen a lot of duty over the years!
Spread cookie dough into 9×13″ sprayed pan.
Spread a package of chocolate chips over top of batter and bake in preheated 350 oven for 5 minutes.
After baking the bars for 5 minutes remove from oven. You can see the chocolate chips have softened slightly.
Using a knife, swirl the knife through the batter in twirls and swirling pattern until the entire pan has been swirled.
This is what the batter looks like after I’ve swirled the knife through the batter in 3-4″ swirling patterns. I don’t use a heavy hand with this. I use large swirls rather than tiny ones. This way the swirls stand out more beautifully when baked. (You want to be able to see the peanut butter and not just the chocolate. If you over-swirl it you won’t be able to see any peanut butter!)
I baked the pan another 20 minutes before removing from oven.
Here’s another look at what the pans look like after coming out of the oven.
Here’s a close up of the swirling patterns I used on this delicious bar.
Here’s a mound of these tasty treats. Is this your plate or mine?
These are so quick and easy to bake. You can have a pan of these fabulous bars ready to put in your oven in about 5 minutes!
I think these pictures on the white plate make it a little easier to see the texture and detail of these decadent, marvelous peanut butter and chocolate bars.
Here’s the recipe.
