Peanut Butter Frosted Brownie ~

Well, yesterday Nate ran the NYC marathon. It was his 7th marathon overall and his 4th time running New York. A lot was riding on this marathon after the 2012 Boston marathon heat wave, and the fact that Sandy caused last year’s NY marathon to be cancelled.

Nate's 2013 NYC marathon ~

Nate had a goal to finish under 3 hours since his last marathon he ran in 3:03. The temperatures were perfect this year but it was VERY windy. To give you an example, this year’s male winner, Geoffrey Mutai, finished in 2:08:24 which was well off his course record of 2:05:06 set in nearly perfect conditions two years ago. 3 minutes to an elite runner is huge. Nate ended up finishing in 3:24:21, which he wasn’t completely happy with, but it’s still an amazing time! I’m so proud of my hubby :)

On to the recipe…since the last recipe I gave you guys was a healthy one, I figured I’d include a very unhealthy one to go with it. I mean, you’re probably having sugar withdrawal since your halloween binge, so this should help with that.

Peanut Butter Frosted Brownie ~

These brownies were another Nate-inspired recipe. You see, we’ve been stopping by our new house a bunch since we closed on it back in August, and there’s a deli nearby that has the most amazing peanut butter-frosted brownies. The brownie itself is really moist and delicious, but what takes it over the top is this really thick layer of peanut butter frosting- the really sweet kind. That frosting must be like 1/2 inch to an inch thick!

So I set out to recreate the brownies for Nate since I know he loves them so much. Plus, it will probably save us money in the long run since I could see Nate stopping by the deli a little too often to grab a brownie once we finally live nearby ;)

And for those of you that have been wanting to know about how our house stuff is going, we officially got the permits on Thursday! The contractor bids were also due on Thursday and on Tuesday I will be going over everything with the architect so I can make a decision as to which contractor we will hire. 

I think that once I narrow it down to two people, I should probably meet with them to really get a feel for whether I could work with them. I’ll share our finalized house renovation plans with you guys soon! Hopefully demolition can start in the next 2 weeks!!

Thick Peanut Butter Frosted Brownies
Yields 18
Write a review
  1. 2 sticks unsalted butter, chopped into small pieces
  2. 6 oz. dark chocolate, chopped
  3. 1 cup granulated sugar
  4. 1 cup brown sugar, packed
  5. 4 large eggs
  6. 2 tsp vanilla extract
  7. 3/4 cup semisweet chocolate chips
  8. 1.5 cups flour
  9. 2 tsp baking powder
  10. 1/2 tsp salt
  1. 6 Tbsp shortening (i.e. Crisco)
  2. 2 Tbsp unsalted butter, room temp
  3. 3/4 cup creamy peanut butter (like Jif or Skippy, not "natural" pb)
  4. 2 cups confectioners sugar
  5. 1 tsp vanilla extract
  6. 2 Tbsp water
  1. Preheat the oven to 350. Line a 9x13 pan with foil, letting the excess hang over the edges. Lightly grease foil and set aside.
  2. In a medium, microwave-safe bowl, combine the chocolate and butter for the brownies. Microwave in 1 minute increments at 50% power, stirring in between, until the chocolate and butter are melted and smooth.
  3. Whisk in the granulated sugar and brown sugars. Whisk in the eggs and the vanilla. Add the flour, baking powder and salt. Fold the dry ingredients into the chocolate mixture with a spatula until combined. Stir in the chocolate chips.
  4. Pour the batter into the pan and bake for 30 minutes, until a thin knife or toothpick inserted in the center comes out clean or with a few moist crumbs. Remove brownies from the oven and allow them to cool completely.
  5. Once brownies are fully cooled, spread frosting (directions below) evenly over brownies. Remove from pan using foil "handles" and cut into pieces.
  6. Store brownies in airtight container or tightly wrapped at room temperature or in fridge for 3-5 days.
  1. Using an electric stand or hand mixer, combine butter and shortening. Add peanut butter and combine til fully incorporated. Slowly add confectioners sugar and vanilla. Add enough water (about 2 Tbsp) to get to a fluffy, moist consistency.
  1. These could probably last longer than 3-5 days in the fridge, but I personally love them room temp.

  1. Congrats to Nate! These brownies look amazing- chocolate and peanut butter is my all-time favorite combo!

  2. Congratulations to Nate!! He has everything to be proud for… That is so awesome. :-)

    Your brownies looks absolutely delish…You may have just planned my evening for me.. :-) That frosting makes me want to take my finger and just scoop some right off the top!! Yum.. <3

  3. So I tried to make a healthy version of banana bars yesterday and they were an epic fail. My sister so eloquently put it that while they taste good, the texture is as though someone already ate it and spat it back up….she’s always been incredibly kind with her words ;)

    Think I’ll stick to yours instead!

    Congrats Nate :)

    • Haha. My goal in life is to make a healthy yet delicious dessert…but it never quite tastes the same. Since being with Nate, I’ve started to make more fattening things since he needs so many calories to fuel his runs. While these aren’t healthy, they’re worth the calories to treat yourself! And honestly they’re so rich you only need a tiny tiny piece to feel satisfied.

  4. I love how there’s such a nice, thick, fluffy layer of frosting on these. Congrats to Nate! That’s a huge accomplishment.

  5. I love that you re-created this yourself! And brownies – they are always a treat! I find myself constantly craving peanut butter lately (chowing on PB stuffed pretzels) and this is making my craving worse. Congrats to your hubby for finishing the marathon – it’s really an amazing accomplishment and he has done 7?! And good luck with all the house-related things!!

    • Thanks, Monica! Gosh, I’m addicted to pb…i eat it straight out of the jar. Nate loves his TJ’s pb pretzels. Yum! Yep, Nate’s pretty amazing ;)

  6. a) Congrats to Nate for the marathon!

    b) These brownies look amazing–I LOVE chocolate & peanut butter.

    c) I can NOT wait to see what you do with your house! It’s already such a cute house, and I know you’re going to turn it into something awesome.

    • Thanks so much, Faygie, on all accounts!!! I’m so excited to share about the house :) You have no idea how badly I want these next 5ish months to fly by!

  7. Brownies + peanut butter are two of my favorite things. Yours look absolutely heavenly. That frosting is just calling my name!

  8. consuelohoneyandfigs

    Congrats to Nate, that’s an awesome time and a huge accomplishement!!! And these brownies look like the perfect reward. I’m sure he loved them!
    Good luck with the house stuff, Amy :D

  9. We didn’t have too much Halloween candy lying around, but oh my goodness did I ever overdose on Oreos over the weekend. I’m still feeling kind of weird. Oreo hangover!

    Like with certain hangovers, perhaps I need to brace up and down another cold one aka these brownies. We always knew I was a chocoholic.

  10. Congrats Nate! I’m sending you some virtual happy dinosaurs!

    Your new house must be super amazing with that lovely deli nearby!

    I’m pretty much in love with these brownies, I’m going to make them this week!

    • hehehe, i’ll let him know you went dinos :) Our new neighborhood is awesome…i can’t wait to move. I wish I didn’t have to wait so long. Let me know how you like these!

  11. Congrats, Nate! One marathon is impressive, but seven is amazing. Good work!

    These brownies pretty much look like heaven to me. I love chocolate and peanut butter, and that thick frosting layer is calling my name. I’m so glad you recreated them so I could add a few baby pounds to my stomach. :)

    • I know, I’m seriously impressed that he’s done 7 marathons while I’ve sat on the couch ;) If you love choco/pb, you HAVE to make these. The baby agrees!

  12. I have a co-workers whose birthday is Wed. I’ve decided these are going to be her present. And what a present they will be!

  13. I’m so proud of him too! I am so impressed by all marathon runners! And these brownies? Well, they’re also making me grin. I would love to have one now! Thank you for sharing them!

  14. wow, congratulations to nate, you must be so proud! and i bet these brownies were the perfect reward, they look absolutely delicious! seriously, drooling at the screen right now. can’t wait to give these a go!

  15. Yay Nate! You too have lots to be proud of ;) And I think celebrating with a giant pan of these brownies is the way to go.

  16. yayyy to Nate! I cant decide if like the frosting or brownies better – its so heavenly.

  17. Congrats Nate! These brownies are the kind of sugar rush you need after a huge race like that.

  18. I can’t believe that was Nate’s 7th marathon — incredible!! And what a time too — he must have be highly appreciative of these lovely brownies at the finish line! (or something like that ;-)). I have not tasted a creamy butter frosting like this in ages…. it’s making me melt just looking at it. “…since the last recipe I gave you guys was a healthy one, I figured I’d include a very unhealthy one to go with it” heheh, great line!

    Way to go Nate!!! (and you know…, unlike many other sports, marathon running is something you can keep doing for years and continue to get better at – how cool is that?).

    • I know! and it would have been his 9th if the boston weather from 2 yrs ago and the hurricane last year hadn’t stopped him! I absolutely hate typical buttercream- it’s too greasy and not sweet enough for me, so i was determined to make the super sweet, non-greasy, fluffy frosting of my dreams…and i think i did it!
      Yeah, Nate said that for men, their prime years are their 30s i think…so he has almost a decade to keep improving! Thanks, Kelly :)

  19. huntfortheverybest

    that frosting looks amazing!

  20. Yay for Nate! I’m so impressed with anyone who can run a marathon.
    These look like the most prefect brownies ever! Love the thick layer of frosting on top.

  21. Congratulations to Nate. Seven marathons! What a commitment to jogging. And I love the action shot! I think any time under four hours is an enormous achievement xx

    • Thanks, Charlie! Yep, he’s pretty motivated! He goes out even when it doesn’t feel like it…that’s certainly more than i can say since it’s been a couple years since I set foot in a gym ;)

  22. Congrats to Nate! Wow, 7 marathons? You must be proud Amy! These look fabulous! Love brownies. Love it more with that delicious PB frosting. YUM!

  23. Elizabeth @

    I’m a new visitor to your blog, but I can already tell we’re basically BFF. Anyone who puts that much peanut butter frosting on a brownie has got to a be a soul mate! Congrats to your hubby on his marathon finish, he deserves another brownie!

  24. Nate’s done so well…congrats! Love the look of the brownies..YUM

  25. I have a feeling, running a marathon would take me a solid 5 hours, so the fact that Nate finished his in just over 3 is INCREDIBLE!
    These brownies look so delicious. I want all the peanut butter frosting too.

    • Uh, it would EASILY take me 5 hours. I somehow got myself to run a half about 5 years ago and it took me almost the amount of time it takes Nate to run a marathon, haha. Thanks, Alyssa!!!

  26. I guess Nate can request a rich brownie like this with all the running he has been doing! I’ll just have to bike a few more miles to make up for the extra calories! I’ll never turn down a bite of dessert!!

  27. Way to go, Nate! I would probably run a marathon in….. idk, maybe like 3 days? The time it took me to run part of it, then pass out, then wake up and finish? Maybe I would be able to finish it if someone was running in front of me waving these brownies in front of my face. ;)

    I’m TOTALLY making these this weekend – Aaron’s been complaining that I haven’t been baking enough lately (whenever he doesn’t have treats to take to work, all of his coworkers ask him if I left yet… and if I’m available to bake for them instead, LOL!)

    • Hahahah, taking a nap mid-marathon is a great idea, Natalie! Let me know if you make these and Aaron likes them. Nate was saying there was no dessert in our apartment and I wasn’t in the mood to bake so I just bought funfetti cake mix with a tub of icing. SO GOOD ;)

  28. Love the brownie-frosting ratio! You are onto something good here. ;)

  29. Your Peanut Butter-Frosted Brownies look amazing. These would be wonderful for afternoon tea or any time snacking. :P

  30. so huge congratulations to nate! that’s incredible, and there’s nothing at ALL disappointing about his time. If he’s down on himself about it, let him know that i’d STILL be running the marathon, soooo. :)
    these look CRAZY, amy. I’m one who thinks that frosting on brownies – like normal chocolate frosting – is pretty decadent, but peanut butter?!? that’s definitely over the top. and i love the color of the frosting, too; back when i had big cake plans for my birthday (a long time ago, and obviously i never got around or got inspired to make a cake), i had thought of a layer one that i thought would be good with a peanut butter frosting: i just didn’t have a recipe for it. now? i do. so maybe that cake gets made after all. :)

    • Thanks, Shannon! I’ll pass along your congratulations. I keep telling him he should not be disappoint with his time because it’s freaking amazing. Plus, he has many more years to do better if he wants.
      I would never have thought to frost a brownie, because i mean brownies are already pretty decadent, if i hadn’t had this one at the deli near our house. I couldn’t get it out of my mind! Make this pb frosting! Omg, it would be so good on a cake. It’s not that gross greasy buttercream- it’s the crazy good sweet stuff :)

  31. Wow, congratulations on his 7th marathon! That’s quite a feet. I would be proud to make it through the finish line at all, none the less in his time! These brownies sound like the perfect way to celebrate. There are very few chocolate things I can think of that wouldn’t benefit from a heaping pile of peanut-butter frosting on top, so I know they must be good!

  32. Congrats to Nate! Love the thick frosting of these brownies, yum.

  33. Hooray for Nate! After the marathon, I think he deserves a pan of these scrumptious brownies!

  34. Well done, Nate! The NYC marathon looks awesome – and I’m amazed that it was his 7th, whoohoo! I can’t stand brownies on their own, but I love peanut butter and/or caramel with them. :)

  35. yay! congrats nate on completing your 7th race! a delicious treat to celebrate ;)

  36. So…I can blame the wind on my abominable marathon time? :P Most of it was due to the fact that I made us stop and stretch at every mile lol. and Nate still did AWESOMELY! It was definitely a tough day to race…everyone I know ran slower than they expected.

    Oh to have had these brownies at the finish line…they are pure beauty!!

    • Joanne, you can blame whatever you want on your time, because even a PR would have paled in comparison to what you had waiting at the end of that race! ;) Congrats again!!

  37. Mouthwatering pictures

  38. Oh my!! These look amazing!! I love the ratio of frosting to cake! So good! Also congrats to Nate!! That is so exciting and such an accomplishment!

  39. Congrats to Nate! These must have been such a treat! Yum!

  40. OMGGG this looks DIVINE:) your blog is now my addiction haha.

    LOVE Maria at inredningsvis – The Swedish home decor blog

    • Thank you so much, Maria! Sorry it took me so long to respond. Your comment went to spam :( I’m going to go check your blog out…i love home decor blogs!

  41. I am amazed at anyone who even goes NEAR a marathon. I mean, anyone who runs a 5K at 8 am on a Saturday morning is a hero in my book. Congrats to Nate. Congrats to these brownies too, for lookin’ so good.

  42. These brownies look FAB. For real! And congrats to nate! My boyfriends sisters husband (What a mouthful) ran in that marathon too! I’m not sure what time he finished at but it was pretty neat to see photos of him.

  43. Kudos to Nate for running the marathon! I’ve only ever done a 3K.
    Gosh you can never go wrong with a brownie frosted with PB sugary goodness! I want these asap! They look so so yummy. :)

  44. That is 26 miles right? 2 hours? 3 hours? Can’t even imagine. REspEcT! I’d have to be running some marathons though to have these around the house. That peanut butter frosting just looks so light and fluffy. good stuff.
