Oreo and Peanut Butter Brownie Cakes

Well these naughty little treats are well….naughty but oh so necessary. There are a bit like my Brownie Covered Oreo’s from last Christmas but enhanced with layers of peanut butter and a double decker stack of Oreos in each little brownie cake. They are simply prepared in cupcake liners.

Hope you enjoy this ultra sweet little cake 🙂

Ok, I have to brag about this brownie mix from Trader Joes for a second. I know not everyone has a Trader Joes near by, however if you do, get a load of their ready to pour baking mix. I am in love! Other than a brownie mix, you just need some of your favorite peanut butter and some Oreos. You can even use the Trader Joe’s Jo Jo’s 🙂

Break out 24 Oreo Cookies.

Some of your favorite peanut butter.


Spread a teaspoon of peanut butter over Oreo #1.


Press a second Oreo right on top 🙂

One more teaspoon right on top.

Place the little stack right into a cupcake lined muffin cup.

Like so 🙂

Take your brownie mix….

…and spoon a couple tablespoons right over top, letting it run around the edges of the cookies.

Mmmm! Time to bake! 350 degrees F. for 18-20 minutes.

Ahhhh, wait until you cut them in half. Too fun!


Oreo and Peanut Butter Brownie Cakes

1 box brownie mix, 8×8 inch size

24 Oreo Cookies

1/2 cup creamy peanut butter

1. Preheat oven to 350 degrees F. and line a 12 muffin cup baker with paper liners.

2. Prepare brownie mix according to package directions. For each cupcake cup spread 1 teaspoon of peanut butter over 2 Oreo cookies and stack them on top of each other. Spoon 2 Tablespoons of brownie batter over each stacked oreos and let it run down the sides of the cookies. If you have left over brownie batter, bake separately in a separate baker or muffin tin. Bake cookies and brownies for 18 to 20 minutes, until brownies are cooked through. Let cool completely then serve.

Makes 12 servings


Enjoy! Come back soon 🙂

    Every single one of my batch stuck to the bottom of the cupcake papers. You should mention that, or has anyone else had this problem?

    Yummy omg so good just made them … One suggestion add a bit of brownie batter to the bottom of the baking cups before you put the Oreos in

    I made the oreo peanut butter brownie cakes for Superbowl 49 and they were a bit hit. I did not have enough oreos to make the last six using two oreos in each brownie, so the last six only had one oreo and they were just as delicious as the brownies with the two oreos. The recipe was a success and the Patriots are the Superbowl Champs what could be better than that……Enjoy

  6. Tracy

    I have made these a handful of times since finding this recipe a few weeks ago and they are always well received! Very easy to make and they taste absolutely amazing! Thank you for sharing!

  7. Terry

    Made these and they came out perfect. Not hard and the paper did not stick. Just followed the recipe but used a brownie box mix. Baked for about 18 min. or until the tooth pick came out clean.

  8. Rene

    I made these last night for my co-workers. I kept checking them to see if they were ready in the oven, and they didn’t look done. So I cooked them longer than the 18 minutes. DO NOT DO THAT!!! They were as hard as a stone! If you make these, take my advise, and follow the directions for the oven time. Don’t make the mistake I did, thinking that a few more minutes won’t hurt!!!

  9. Heidi

    I make these for my husband’s work every time they have a pot-luck. They call them “crack in a cupcake”. Every potluck I ask him if I should make something different. Nope, they all want their crack in a cupcake. From the guys of the sunrise shift at the Ontario UPS hub, thanks for the recipe.

  10. James

    Just made these for my friends and one has just said it’s probably the best brownie he has ever eaten!!! Thank you… MOST definitely going to bake these again!!!!!

  11. Kelly

    I made this a bit differently today. I used one oreo, opened it, put peanut butter on one side of the cookie then put the cookie back together. Did everything else the same. This way I can make more. I made 30 of them! Yummy.

  12. Carol Homer

    My family really like these but my liners stick to the bottom of the cookie and won’t completely peel off. Any thoughts?

  13. andy

    This is disgusting. I cant believe what crap people will eat. why dont you just save yourself the time and effort of making these treats and just poor the sugar down your throat and give a heads up to your doctor to have your diabetese medication ready.

  14. Suz

    Saw this and had to try immediately! I didn’t use double stuffed just traditional Oreos, reduced fat kind also reduced fat creamy peanut butter to lower cal and fat content. To ensure they didn’t stick I sprayed Pam into each cupcake liner and it made it much easier to peel away. Also as someone had mentioned I melted butter and dipped both sides of all the Oreos in and it worked perfectly to soften them up! I’m sure they’ll be a hit for Christmas!

  15. Uh, yum! I’m finally moving to an area with a Trader Joe’s, so here’s to hoping they still sell that brownie batter. I’m going to be all over that!

  16. barbara lenger

    Tried these Oreo and peanut butter brownies – twice and both time the brownie part was fine but the orea tasted burned. Had it on the top rack and second time we lowered the oven temp to 325 degrees and they still burned..What did we do wrong? Any suggestions?

  17. Yuuummmmm!!! They look delicious, simply have to have a go at making these…and then probably spend the following week in the gym!

  18. Really?!

    That is nasty. Everyone seems to be excited about these, but I don’t see how you could feed your kids (or yourself for that matter) something like this. And we wonder why America has an obesity problem. Jenny looks good though, I’ll give her that, so she must not be eating too many of her own sweets.

  19. Holly

    These are in the oven as I type! Easy to make and the house smells incredible! ๐Ÿ™‚ ๐Ÿ™‚ Can’t wait to eat them this weekend ๐Ÿ™‚

  20. Nina R.

    These were a hit today! Everyone at work loved them, I’m not a sweets person but I had one with ice cream and it was Delicious! Thanks for the recipe!

  21. Stephanie

    I made these with the organic ingredients I had on hand, the 365 brand of “Oreos”, Dr. Oetker’s brownie mix, and Earth’s Balance peanut butter. I added a little boiling water to the brownie mix to get the right consistency. My 8 and 5 year old girls who helped were so impressed with how these baked up and were licking their lips as they ate them. Each brownie weighed a ton, man. These were decadent!! I would be curious to see how a single Oreo and less brownie mix would bake up in a mini muffin pan. I will need to experiment! Also, wondered if anyone has substituted Nutella (or equivalent!) and if it worked as well as the peanut butter. Thanks for the fun recipe!!

  22. I can’t believe I haven’t thought of doing this. These are things we consume all the time. Why not put them together. This is a must try. Thanks for the post.

  23. Erin

    Made them tonight for hubby and guests- very yummy!! I made these with just one double stuff Oreo and PB spread on top covered in the brownie batter. I think everyone loved them before they even tried them after I told them the main ingredients ๐Ÿ™‚

  24. iceladypnsfl

    Can I say yummy!! These have been the favorite so far this Christmas baking round. Had to bake a round 2 of these, since when I make them there are 14. We love Oreos!!

  25. Tammy

    OMG! I am making these tonight! I have a bag of oreo’s and a box of brownies that need to eatten. These look amazing. I am bring them to a pot luck lunch at work tomorrow. Everyone is going to die!!!

  26. These look SO AMAZING. I’m baking for AustinBakes – a bake sale to raise funds for the recent Central Texas wildfires – and I’m making these! I blogged about it here: http://www.foodgoodlaundrybad.com/2011/09/austin-bakes-for-bastrop.html

    I linked back to your recipe and your blog – so amazing! I borrowed an image, too, since I haven’t cooked these yet, but I gave plenty of credit and left your watermark. If you need me to take it down, I understand – email me and let me know!

    Thanks for sharing such a great recipe!

  27. Louanne

    You are a genius! I just pulled these out of the oven and took my first bite. Now I am in chocolate, peanut butter heaven! Thanks for posting the recipe.

  28. Catriona

    Just this minute made these really for no reason other than curiosity! They are SCRUMMY!!! I just had one, fresh from the oven. However, in an effort to help my self-control, I only made 6 and am freezing the rest uncooked, with a view to defrosting them before baking at a later date. I really don’t need too many of these hanging around in the kitchen…!

  29. just put a batch in the oven. i accidentally got the TJ’s brownie mix that’s pour-and-bake, but hey, it makes the clean-up that much easier. i LOVE the idea of using pumpkin instead of peanut butter. i think i’ll try that next time. yum!

  30. Sarah Reaves

    Made these last night for GNO/Bunco party. What a hit! Delish and EASY! I used the Reynolds baking cups and they peeled very nicely from the Brownie. I used the Pilsbury Chocolate Fudge box. DELISH!

  31. Emma

    I just put my second batch in the oven and taste-tested the first. It’s simple, cheap, and great for a college budget. One thing I would say is that they are VERY rich, so don’t let you eyes be too much bigger than your stomach. I put too much peanut butter in the first batch, so the sweet-salty ratio wasn’t right, but that was easily fixed and hopefully the next batch will taste even better. I used the cheapest brownie mix (fudge variety) and “Oreo”-type cookies I could find and had no problems with taste, texture, or thickness. I used 2 and 1/2 packs of cookies and a full box of brownie mix, which made 2 dozen.

    Thanks for a great, guilty-pleasure treat!

  32. Bianca

    I don’t live in a state that has Trader Joe’s…how can I still make these?! I desperately want to try…will I just have to mix together all the brownie ingredients of another brand on my own? Or is there something similar I can try?

  33. I want to make these for my sons’ double birthday party tomorrow (as those are all of their favorite things!) but no idea what icing to use. I know someone said above it would be too sweet but it’s not a cupcake without a little icing.
    Any suggestions on one that wouldn’t make these over the top sweet? Maybe peanut butter icing?

  34. Holly

    Made these yesterday. Delish! Easy! Amazing! The oreos remained crunchy. I was hoping for a softer oreo after being bake but I also think that I may have slightly overbaked them. Either way, will make again!

  35. Stacy

    Does anybody have any good tips for thinning out a brownie batter? I have a great brownie recipe I make but it’s a bit on the thicker side. I’d rather use that than buy a mix if I can.

  36. Jenna Leigh

    I wonder if this would work with some pumpkin in place of the peanut butter. Pumpkin chocolate chip cookies are my favorite and this could be an awesome riff on those. PS, love everything you do on here, and so do my co workers when I bring your recipes to work to test out on them.

  37. Scott

    I just made these and I do have to say….GENIUS. They are so good. I put my own twist on the second batch I made after the first. Instead of peanut butter, I made homemade strawberry puree and replaced that with the peanut butter. AMAZING. This is such a great recipe.

  38. Kim

    I tried these over the weekend and they were quite a hit with everyone. While pulling out the brownie mixings, I thought to myself… hmmm… I wonder how this would taste with Nutella instead of peanut butter. I have to say that everyone who tried one really enjoyed it.

  39. Lauren B

    I made these tonight with my sorority sisters at school – everyone was in awe of how AMAZING they were!!!
    we’ll definitely be baking our fair share of your recipes in the year to come ๐Ÿ™‚

  40. Just made these. They were very good. I found if using the Trader Joe’s brownie mix I could get 21 brownies made and that way I didn’t have to bake off the rest of the brownie mix (or maybe I didn’t put in enough batter? I think I did though as it was very full). Personally I think I’d like a little more brownie in it so I may try it with just one oreo and some peanut butter on top and bottom. I love the addition of the peanut butter! The only other problem I had was that my muffin wrappers stuck to the brownies a bit. I waited as long as I could to dig in so maybe it was because they were still a bit warm. Anyway, I love your creations. They are creative and bring something new to old ingredients.

  41. This smart Oreo inclusion reminds me of a smoothie served at Paul’s bakery in London with… a French macaron inside! Bravo Jenny for the creativity and the simplicity!

  42. Annette

    Ooohhhh going to try these beauties! I’m a little freaked out b/c aside from the tidy looking kitchen and beautiful nails I’d have thought you raided my pantry – staples. I’m going to try a different brownie mix, though — we weren’t fans for the TJ’s brownies in a bag (but clever idea)…. AND this recipe can work for my dairy allergic daughter!!! Thanks

  43. Sara

    Made these with what I had on hand…double stuff Oreos, creamy Jif, and a 9 x 13 brownie mix. I made the brownie mix with the “fudgy” version, but I’m thinking the cake-like version might have been better (more runny). One mistake I made was not using enough peanut butter. I used less because I was afraid my stack would be too tall with the double stuff Oreos, but I really couldn’t taste the peanut butter. I made a total of 18 of these, and it seemed perfect with the 9 x 13 mix. I put the mix on the Oreo stack, let it sit for a few minutes, then added more. Turned out perfect. They baked for about 25 minutes.

    I just put a triple batch in the oven. This is what I’ve discovered: You need to really make sure to match the brownie batter consistency with what Jenny pictured above. On my first try the batter was thicker and would not run down the sides so easily. When that batch started to cook in the oven, I had no control which way or direction the batter would slide, so some went off the side. I used the Ghiradelli brand for the brownie mix, added vanilla extract and a TB of cocoa, replaced the water with milk and replaced the oil with butter. I used the Halloween Oreos that are in the store now because I am making these for my daughter’s Fall Festival at school. I had cupcake papers that are black w/ a candy corn design and then I am going put these in a clear plastic bag and tie it off with an orange ribbon.

      1. La-a

        GuRl, puuulease. You be trippin out!! *z-snap* JeNnY knowz hur sH**t! If it ain’t broke, don fix IT! REALLY?, halloweenoreos? that sh**t cray!

  45. I saw this on FoodGawker and had to come comment! I have made cupcakes with whole oreos in them, but that is nothing compared to this! This is such a creative idea and they look amazing! ๐Ÿ™‚

  46. AJ

    These remind me of my freshman year of college when I started dipping everything in peanut butter: oreos, red vines, graham crackers. And I gained the weight to prove it. Ha ha. But these sound to-die-for-yummy. LOVe it!

  47. So I was tempted enough to go ahead and make these with my 7 yo daughter this afternoon….we just taste tested one….definitely a yummy combination. ๐Ÿ™‚ My crew is going to like ’em! I went ahead and used a pkg of Oreos along with a 9×13 pan size brownie mix. I didn’t measure the peanut butter(creamy Jif-not natural variety) I just used my Pampered Chef small spreader and spread a layer on each Oreo. Prep time was about 10 minutes and bake time was closer to 30 minutes. Total made 21 cakes.

  48. love this idea!…
    but I think I’d love to mix in confectioner’s sugar with the peanut butter.. I love doing that when I mix peanut butter in truffles or any baked goods

  49. Kati

    I’m thinking a cream cheese, sugar, egg mix in place of the peanut butter and I might die of gooey goodness. thanks for the amazing ideas!

  50. Jenny, I think you’re trying to kill me. These look SO fun. I’d love to pass them off as brownie cakes and then see people’s faces of surprise (pleasant surprise, I’m sure!) when they bite into them. ๐Ÿ™‚

  51. Having tried your Oreo stuffed cookies and making them a regular bake in the kitchen, these I must try! I don’t like Peanut Butter but I’m sure it’ll be equally as nice with something like Nutella instead. Thank you for another wonderful recipe

  52. Jenny these look amazing! I have that exact kind of peanut butter & oreos on hand. And I’ve had that TJs brownie mix IN MY HANDS about 7 times and have never bought it b/c I have always thought…well, how good could it be. Ok, now I know.

    And wow, you are sooooo creative! I am impressed with the cross section slices in the 1st pic…so professional!
