I love brownies. I love peanut butter cookies. I LOVE Peanut Butter Cookie Brownies!!! AKA Polka Dot Brownies :0)
We’ve got an easy homemade brownie batter studded with globs of peanut butter cookie dough for a chocolate peanut butter lovers dream come true.
These little squares did NOT last long my friends. My husband barely even got to taste them because the boys and I scarfed them up so fast. He’s learning that he has to be quick if he wants to get in on the good stuff. Otherwise it’s like, “Um, didn’t I see a pan of brownies on the counter a few days ago?” Sure did buddy, you snooze you loose around here!
You should probably make these too, it being the start of the weekend and all! Happy Friday!

Look at those luscious peanut butter blobs! YUM to the max!
Thanks so much!
I got lazy & just mixed both brownie & cookie together… Very Yummy!
Love it, Doris! I’ll have to try that.
Peanut butter plus brownies, what a great combo!
OMG, “you snooze, you lose” would have been my Dad’s reply to such a question. He will be all over this, as will Hubby as soon as they know about them. Which might be just after the taste testing is done.
Made them for a gathering today and they were a hit. I just used cashew butter instead of peanut butter (thought I had PB but was out!)
Oh YUM, I might have to try that next time!
Making these now so can’t comment on how yummy they are and how long they didn’t last yet… Just wanted to note in the directions for brownies it says to mix in baking soda not powder. :). Looking forward to sharing these with my hubby. Kids can have some tomorrow….if there’s any left !
Thanks for pointing that out. I have fixed it. Hope you guys enjoy!
They’re so good! My husband had 4 so I’m thinking its a good thing I doubled the recipe!
Yay!
How long did you time the double batch?
Kate, I haven’t had a chance to try a double batch. I’m guessing 10 more minutes in a 9X13 pan.
Can you use the box brownie mix and the store cookie dough roll? Just trying to think of something quick.
Hi! I’m not sure if that will be the same amounts of dough for each as this recipes makes, but you could definitely try them and see.
I loved this idea – for a quicker version I used a box of Ghiradelli brownie mix and a bag of Betty Crocker peanut butter cookie mix. I assembled both according to package directions. I spread the brownie batter in a 9×13 pan and plopped about half the cookie dough as you did in the pictures. These baked at 325 in a metal pan for 28 minutes. I made cookies with the remaining dough. These were good – next time I’ll make sure to have vanilla ice cream on hand to add to the goodness! Thanks for the great idea!
Thanks Melanie, great shortcuts!
Sure can! I did!
Sure can, I did!
How do you prevent the eggs from cooking and becoming globs of boiled egg pieces when you add it to the hot sugar that you recently removed from the heat?
Jackie, you can either just let it cool slightly, or you can temper the eggs by adding a little bit of the brownie batter to them before adding the whole mixture in. Hope this helps!
Delicious and an easy from scratch recipe! But after 30 minutes in the oven the brownies were not baked at all. Like, totally still batter, jiggling when I pulled them from the oven not baked. I had to almost double the baking time in order for the brownies to be baked through, but that obviously affected the peanut butter cookies. Any suggestions or thoughts? I followed the recipe and instructions meticulously, and I’ve never had this happen to me before when baking. Thanks!
Hi Jessica – I’m glad you still enjoyed them, but I’m a little stumped as to why it took so long to bake. I’m wondering if it had anything to do with the position of your oven rack, or the type of pan you used? Glass versus metal?
This happened to me, too! Plus, my peanut butter batter didn’t really turn into much of a dough, but rather clumps. I ended up just spreading the whole thing over the top, but 30 minutes in and still completely batter brownie mix. I’m hoping the additional baking time doesn’t burn the peanut butter dough!
This happened to me too. The peanut butter cookie part was so dry it was almost inedible. Especially since the blobs were so small. The pb cookies were like crispy while the brownie batter was fudgy.
A little dry, but tasty. Would be better with ice cream or a glass of cold milk!
Hi, I’m still a teenager (no kids or husband!) and I don’t cook or bake that often, and I’ve found I’m not really the greatest at it either. However, I used this recipe and it was amazing! My parents, siblings, and boyfriend were all super impressed! If only everything could be so easy to follow. Thank you so much!
Hey that’s awesome! So glad you all liked them, and you just keep on baking, mkay?!? :0)
I want to make these for my coworkers for a potluck, but have a couple that are allergic to peanuts…. do you think substituting sugar cookies or chocolate chip would still taste as delicious?
don’t worry, made the peanut butter recipe for my hubs and he literally ate the entire pan!
I think chocolate chip is a great idea! Glad it was a hit!
This is the second time I’ve made these and my hubby and kids love them as much the second time as the first!
Awesome! I need to make these again soon myself!
Very moist and cake-like. The peanut butter really came through. Next time I’ll add more cocoa.
Would coconut oil work to sub for the butter?
I have tried subbing coconut oil in a lot of baked goods, and it is usually just fine! Sometimes I like to do a half butter/half coconut oil combination for the first time, and if that works I’ll back down even more. Let me know how it goes if you give it a try!
OMG I have been looking for this for over a year. have you ever made it with oatmeal?
No, but that’s a great idea. I’ll have to try it soon!
These are in the oven right now! I’m hoping they satisfy my 38 week pregnant cravings 🙂 But, they’ve been baking for about 40 minutes and still super doughy on the brownie. I was very careful with all measurements. Baking in a glass pan. Is that the problem?
Hi Raschelle, I hope these brownies do the trick for you. And yay, you are so very close to meeting baby! I would keep cooking until the brownie seems a little more set. I never think much about the difference between glass and metal pans for baking, but this post is helpful in knowing how they baking differently. Hope you enjoy!

Made today 3/28/16. Did not like one bit. The peanut butter cookie batter was very bland. Would not make again nor recommend to anyone. I think it’s the lack of brown sugar in the recipe.
I made these yesterday, and they turned out awesome! The only things I changed- I subbed 1/2 butter for coconut oil, turned out very well. Also, I only had crunchy peanut butter on hand, so I used that but added an extra ~1 tbs for the cookie portion. I baked it in a metal 9 x 9 pan, and they were done perfectly after 30 minutes. Thanks for this fantastic dessert recipe!
Becky, thanks for letting me know how they turned out – so glad you liked them!
My brownie batter was much thicker than yours looks. Did I mix to much??? My cookies ended up just sitting on top, in the oven now hope it still works.
Hope you enjoyed them Aimee! Not sure why your batter was thicker.
I made these yesterday. The brownie is good, fudgy and chewy. I liked the concept of the peanut butter cookies, however I don’t think it works that well. It could use more peanut butter flavor and the cookies just sit in the brownie as thick blobs.
