Soft and Chewy Peanut Butter Chocolate Bars
I have so many peanut butter dessert recipes on my blog, but you can never have too many. That’s what I tell myself anyway.
When I want an easy, fuss-free recipe that I know everyone will love, I call upon my trusty blondie base. With 35+ versions and counting, it never lets me down.
It’s an easy recipe to memorize because everything is ‘one’. In the 1 bowl used, melt 1 stick of butter, stir in 1 egg, 1 cup of brown sugar, 1 tablespoon vanilla, and 1 cup flour.
For these peanut butter chocolate chip bars, I added 1 cup chocolate chips and peanut butter. The only thing that’s not ‘one’ is the amount peanut butter (1/3 cup).
I made these peanut butter chocolate chip cookie bars in a hot, un-airconditioned kitchen which contributed to the melty look!
These peanut butter chocolate chip bars are super soft, slightly chewy, buttery, and peanut buttery. Between the butter and the peanut butter, they’re super moist and just melt in your mouth.
There’s an abundance of chocolate in every bite. There’s no other way to do chocolate other than in abundance. These peanut butter bars were definitely worth heating my house up for.

How to Make Peanut Butter Chocolate Bars
I love how quick and easy these chocolate chip peanut butter bars are to whip up! Here’s an overview of how the bars come together:
- In a mixing bowl, whisk together the melted butter, egg, vanilla, brown sugar, and peanut butter.
- Stir in the flour and chocolate chips and mix until just combined.
- Turn the batter into a greased 8×8-inch pan and sprinkle a few more chocolate chips on top for good measure.
- Bake the peanut butter chocolate chip bars until a toothpick inserted in the center comes out clean.
- You’ll need to let them cool in the pan for 30 minutes before slicing and serving (I took these photos in Aruba on a very hot day, so my bars were pretty melty).
Recipe Tips
Glass vs. metal pans: For this recipe, I used a metal 8×8-inch pan. If you bake with a glass pan, it may alter your bake time since metal conducts heat better than glass.
Flour: I’ve never made these peanut butter chocolate chip bars with anything other than all-purpose flour, so I can’t speak to whether gluten-free flour or whole wheat flour would work for this recipe. Same thing goes for egg replacers.
Vanilla: If desired, you can scale back on the amount of vanilla you add to these bars. I always add at least 2 teaspoons of vanilla to my baked goods because I love the flavor it lends to any bar or brownie I make, but feel free to adjust the amount to suit your personal tastes.
Recipe FAQs
Yes, you can easily double the ingredients in this recipe and bake these peanut butter chocolate bars in a 9×13-inch pan. Just note that the bake time will differ, so keep an eye on your bars near the end of their bake time.
This recipe calls for an 8×8-inch metal baking dish. If you only have a 9×9-inch pan on hand, that’s fine. Just note that the bars will be thinner and that you’ll need to reduce the bake time.
No, oil can’t be substituted for the melted butter in this recipe. Your bars won’t have the correct texture if you use oil!
Of course! You can use peanut butter chips as well in these peanut butter bars, or you can chop up a chocolate bar if you don’t have chips on hand. White chocolate chips are also tasty with peanut butter.
I’ve only made the peanut butter bars recipe as written. You might be able to use another nut butter if it’s a no-stir variety, but I can’t say for sure. Cookie butter and almond butter would by my two suggestions. Leave me a comment below if you try it out and the recipe works for you!
No, you don’t want to use natural peanut butter for these peanut butter chocolate chip cookie bars as it has a tendency to be too oily or to separate. You want to use a peanut butter brand like Jif, Skippy, or Peter Pan.

Readers love these peanut butter chocolate chip bars! Here are just a few of the 5-star reviews that have been left on this recipe.
“I’ve made these twice in the last 2 weeks and they are easy, absolute yumminess! I used 2 tsp. vanilla extract, and definitely be sure to cool (though it was hard for my sweetie to resis!) at least 30 minutes before serving to give the bottoms time to cool and set up a bit. Great recipe I will make and share again and again!” — Amy Miller
“10/10 recommend!!! Came together super fast and was delicious! Thank you!” — Jerica Debruzzi
“These are amazing! Rich and delicious. I doubled the recipe for a 9×13 pan. Based on a previous suggestion in the comments, I used a full cup of Jif vs 2/3 cup (for the doubled recipe). The edges baked up perfectly crispy and the middle was rich and kind of fudgy. Make it and enjoy!” — Jen
“Amazing!!! I’ve already made this 3 times and they are just so delicious. Thank you for the recipe.” — Eva
“I made this recipe for the first time today. I love it! I did use natural PB but it was a no stir version. I had to bake them for closer to 30 mins where I live. Definitely going to use this one again! Thanks for the recipe.” — Alicia

I have made countless batches of these! Seriously the best!
I was a rebel and used oil anyways (this recipe is more versatile than you give yourself credit for!) I doubled the recipe and used natural peanut butter. Instead of 1 cup butter, I used 3/4 cup oil (canola and sunflower blend) and reduced brown sugar to 1.5 cups packed. I also added 1/4 teaspoon salt. They are amazing. Blondies made with oil are where it’s at IMHO. They are more moist and with all that sugar and PB, you don’t even notice they aren’t made with butter! Anyways, thanks for the inspiration!

Glad to hear oil worked, as well as natural PB. Good call to not quite double the oil even though you made a double batch. Salt is always a nice touch with chocolate and PB. Glad this turned out amazing for you!
Awesome recipe!!! Just made these today with my 10 year old daughter and we love it!!!!!!!!!!

I’m glad they turned out awesome for you two!
Could I use self rising flour its all I have?
I would not or the texture will change quite a bit I am guessing.
I cooked it in an 8 x 8 glass pan and for 25 minutes it was still not done. Extra time until it’s done. But it smells amazing
So easy to make I made this with my mom and we loved it we even loved the raw batter
Thanks for the 5 star review and glad you loved the bars!
Can I use oil instead of butter?
no
These were delicious, thank you! However, to me and my family they tasted like super awesome blondes. We didn’t taste the peanut butter! Do you have any ideas – think I could add more next time or would it ruin the bars? Thanks!
Surprised that you couldn’t taste a half of a cup of peanut butter! That is a lot given the size of the pan. Increase it to a solid 1/2 cup and add 1 cup of peanut butter chips would be my suggestions.
Add some PB2 peanut butter powder.
I doubled these for a bigger pan tonight and they are delicious! Just what this pregnant lady was craving.
Thanks for the five star review and I’m glad it was perfect for your pregnancy cravings!
