Peppermint Cookies n’ Cream Brownies

Peppermint Cookies n’ Cream Brownies

Fudgy. Rich. Intense. Chocolaty. Pepperminty. Amazing.

All of these words are ones that I would use to describe these Peppermint Cookies n’ Cream Brownies, which just might be my favorite brownies to date. The response to them in general (as soon as my unofficial tasters no longer had their mouths stuffed full of brownie) was “oh my god.” They had a fantastic balance between being fudgy and chewy. Not overly wet or undercooked, the brownies held their shape very well and were still very moist with a nice chew that meant you could savor each piece slowly as you ate.

The brownies were inspired by a box of seasonal Peppermint Jo-Jo’s – the Trader Joe’s version of Oreo cookies – that I bought last week. The cookies are great on their own, with just the right amount of mint filling to balance the chocolaty wafer. They taste kind of like a high-quality thin mint cookie (but better, in my opinion). That flavor came through very well into the finished brownie, giving the treat a refreshing hit of mint that prevented the chocolate flavor from getting too intense.

I added the cookies into the brownies as though they were chocolate chips, roughly chopping them first with a large kitchen knife to get them down into a manageable size. Some pieces were a bit larger than others, but just about every part of the cookie melted slightly into the brownies. I also garnished the top with a sprinkle of crumbs, so that it was easy to see what kind of brownies these were from a glance, but this is entirely optional. The peppermint flavor will b a surprise whether your cookies are garnished or not since it is so unexpected. If you don’t have access to peppermint Oreo-type cookies, use plain Oreos and add a teaspoon of peppermint extract to your batter. Alternatively, you should be able to use other chocolate/peppermint cookies, such as Thin Mints, as a substitution.

Cut these into small pieces, as they are big and rich. Take them to a holiday party or other gathering where there will be lots of people to share them with, too, or risk being tempted to eat them all yourself.

 Peppermint Cookies n’ Cream Brownies
1 cup butter
6 oz. unsweetened chocolate, chopped
3 cups sugar
1/2 tsp salt
2 tsp vanilla extract
4 large eggs, room temperature
1 2/3 cups all purpose flour
1/3 cup unsweetened cocoa powder
3 cups roughly chopped peppermint oreo-type cookies (approx 18)

Preheat oven to 350F. Line a 9×13-inch baking pan with aluminum foil, and grease lightly.
In a medium-large saucepan over low heat, melt together butter and chocolate, stirring occasionally. Whisk in sugar, salt and vanilla, then turn off heat. Whisk in eggs one at a time, waiting until each is fully incorporated before adding the next. Stir in flour and cocoa powder until mixture is uniform. Stir in peppermint oreo cookies and pour batter into prepared pan. Crush 3-4 additional cookies finely and sprinkle on top of batter, if desired.
Bake for about 35 minutes, until a toothpick inserted into the center comes out with moist crumbs, but not coated with batter.
Cool brownies in pan for about 20 minutes, then lift brownies in the foil out of the pan and place on a wire rack to cool completely before slicing.

Makes 36 brownies (or 48 bite-sized brownies).


  1. OMGawsh! That looks so so so good! I am writing this down right now…I have GOT to try these!!!

  2. Wow, a cookie within a brownie….yum…please send peppermint oreo-like cookies in my direction!!

  3. Wonderful — and one that requires no mixer, too, for those whose kitchens are without or whose mixer is ‘busy’ with other holiday goodies! Love this one, Nic!

  4. I cannot show this recipe to my son. He will insist we make them. Those cookies are like crack. Have you tried the Trader Joe’s Peppermint Marshmallows in hot chocolate? So good.

  5. If they taste as good as your photos—yum! No TJ’s here, so will go with your sub recommendations.

  6. A brownie and a cookie in one. Couldn’t get better, I think? I really like the variety of food you bake.

  7. I am so impressed with the variety of yummy things on your blog..lucky that I discovered it.
    The brownie and cookie combo is excellent…Rich, fudgy, delicious!!

  8. These look amazing! I’ll have to try them really soon. The ingredients are similar to the ones that I use in my best brownie recipe, except that I only use cocoa powder and I don’t use oreos. Yum!

  9. Those look ridiculously good! I’m not an ice cream person, but cookies and cream is one that I really love. The peppermint in there is great too–especially for the holidays. I can’t believe I’ve never seen a recipe like this before–it should be a no brainer–awesome job!

  10. I actually went out in a snow storm to TJ’s to get those cookies. It was totally worth it. These definitely are up there as some of the best things I’ve made from this site (S’mores bars also come to mind). For everyone who is wondering if these are as good as the picture looks, the answer is YES! :)

  11. Shannon – Now *that* is dedication! I’m so glad you liked them as much as I did!

  12. oh. my. god. the most delicious thing to ever come out of my kitchen.

  13. I cannot wait to make these! I bought a huge stash of Candy Cane Joe-Joes this year, because last year I bought two boxes, and when I went back, they were completely sold out! They are one of my most favorite cookies, and I wish they were available all year long.

    Shannon, I’d crawl across the frozen tundra in my PJ’s for these cookies. I’m SO with you!

  14. Oreos aren’t an international brand, FYI. Any ideas on substitutions if you can’t get Oreos (let alone some sort of special peppermint kind!!) in your country? will any sort of hard cookie do? But what about the peppermint? Extract? Hard candies?

  15. These look delicious. If only they fit into the diet…

  16. oh man… i think you might have found the most perfect food to ever exist.

  17. Brought new meaning to delicious….. THANK YOU!

  18. I’ll have you know, it’s all your fault. :=) So there I am at Trader Joe’s, for nuts and frozen vegetables only, and I find myself spying the shelves for a peppermint oreo. Have I ever bought oreos before? No. But suddenly thanks to your talking about them I must. Must. So there’s a box, it’s only $2.49!!! I add four boxes to my cart, then put back three. At the check-out, the woman asks if I’ve had them before. I hope she’ll tell me they’re awful so I’ll say, Uh, no thanks. Instead she says, You’re lucky to get them. We’ve been out all day and people have been asking. The truck just came in and this is the first thing we put on the shelf. Thanks a lot, Nic, introducing an obsession that’s not available. Hmm. Or maybe that’s a good thing. :-)))))))

  19. Oh my gosh, I’m totally making these for a Holiday Bake-Off competition at work…I’ll let you know if I win :) Hmmm, might just have to make a batch before hand to test them out :) They look too delicious to wait until the competition next week!!

  20. I am making this for the treats day on Friday! Even since I bought the packet of Candy Joe Joe yesterday I can’t stop munching them from time to time. This will be a good way to relieve my overeating problem :D

  21. I am making these right now and my kitchen smells amazingly minty. I am taking them to work tomorrow – I’m sure I’ll be very popular!

    Thanks for the recipe – I love your site and am so happy I found it.

  22. I just made these last night. SOOOOO GOOOOOOOOD. I had to give the rest away today so that I wouldn’t eat the entire pan. (Believe me – I am capable…)

  23. hi Nicole, just a note to let you know that I have made and blogged about your brownies! They are delicious, thanks for saving me from finishing the whole pack of cookies on my own. :D

  24. These brownies are devastatingly delicious. I made them earlier this week for Christmas gifts. I have FINALLY found my “go to” brownie recipe. No more boxed mixes for me! THANK YOU SO MUCH!

  25. Wow these look good. I just sent the link to my friend to check out and she put it perfectly – “those look deadly”. I must make them!

  26. Hello!I love your recipes!Anyway,is it possible to bake this in a 8 x 8 inch pan?Heh=D

  27. Would you reduce the time slightly if baking these in a Bakers Edge pan?

  28. Lauren – Yes, I would check it a bit early just to be sure, but the brownies are very fudgy, so I wouldn’t expect the baking time to need too much reduction.

  29. I made this for Christmas Gifts – oh my god they were so delicious. We don’t have peppermint oreo’s in Australia so I used Mint Slice Biscuits. Heaven!

  30. These brownies are amazing! I made them for Sunday dinner yesterday. My mother in-law thinks I am fabulous!

  31. Wow, these are pretty much brownie perfection, as far as I’m concerned. I added about a teaspoon of peppermint extract to the batter, which may have been a mistake, but the texture of these brownies is amazing. “Devastatingly delicious” indeed.

  32. I couldn’t find any peppermint Oreo’s so I just used regular ones and they’re in the oven right now. I can’t wait to try these after reading all the comments.

    P.S. – I wish we had Trader Joe’s in Canada, and Candy Cane Joe Joe’s were in season.

  33. I’m so glad I discovered your site as everything you do is delicious…we belong to 3 flour clubs 2 Bible studies and go to alot of pot lucks…was I lucky to come upon this goodie…it is fantasia in a bar cookie…I don’t think I’ll be breezing so much any longer as where can I find such perfection in cooking…also Maidas peanut bars are an eye opener when served…d

  35. Thanks for the inspiration!!! I made my own batch (just a different brownie base recipe) And they were deeeeeeelish. :) Can’t go wrong with mint oreos OR brownies.. put together!!

  36. We love these…thank you so much! We are making our fourth batch today for a family get-together. My kids love to help by smashing the cookies with a rolling pin. So very yummy and great for a crowd!

  37. I’ve been waiting all year for these cookies to come out again at Trader Joe’s to try this recipe. Can’t wait. I may have to buy a dozen boxes before it is over to make sure I have them after the season is past.

  38. I made these awhile ago with regular Oreo’s and found the brownie itself to bee too dense and it got hard likr rock candy after a couple days (I must have done something wrong).

    I had some ccjj’s sent to me in Canada, found another recipe for ‘chewie’ brownies and used your idea. I’m definitely doing this again!

  39. wow these look amazing! i’m making these today :)

  40. I’ve been dreaming about these all year. Made them last year and they were delicious. Just got a new box of Candy Cane Jo-Jo’s and headed straight to the kitchen to make them again. Thank you for this delicious addition to my holiday baking list!

  41. These may be the best dessert I have ever made. I made them twice in two weeks for two different holiday parties and everyone loved them!

  42. If you can’t get the Trader Joe’s Peppermint cookies, you can use the mint Oreos. I am a big fan of Trader Joe’s, but I actually prefer the mint Oreos. Another advantage (well, not to my waistline!) is that they are available year-round.

  43. These brownies are devastatingly delicious.ouldn’t get better, I think? I really like the variety of food you bake.

  44. I bought the cookies back in January, knowing my sister would be here in March. We baked these together today and they’re yummy good; not as pepperminty as I expected, but fudgy delicious.

  45. This blog makes me realize the energy of words and pictures. As always your things are just gorgeous and I am grateful that you let us look in! Keep coming up with ideas.

  46. Peppermint cookies are my best among all cookies. i have tried using the ways you told. the taste was awesome..

  47. These brownies were hands down the most delicious that I have tasted. My wide baked these for our family today and all I can say is WOW!… oh and Thank You for the recipe!

  48. i made these and everyone ABSOLUTELY loved them… they were gone in no time, and people have been requesting i make some more ASAP!!! great recipe!
