Is there such a thing as too much peanut butter? If you’re thinking “yup, there is!” then you should probably leave now because you’re really not going to like these brownies. They involve peanut butter in three forms. But you know what? They’re not overly omg sticking to the top of your mouth peanut buttery. I think all of that chocolate really helps balance things out. If you don’t love peanut butter, you must at least love peanut butter and chocolate together, right??

I first made these chocolate peanut butter brownies wayyy back in 2009, after seeing the recipe on Grumpy’s Honeybunch. Sometimes I laugh to myself when I re-read my old posts because I say things like, “next time I’d add peanut butter into the batter.” Okayyy, Sues, then why the heck didn’t you add peanut butter into the batter before posting about them?? It’s like, “here, I’m giving you a recipe, but there are like 10 things I’d do differently next time I make it, so…” Anyway, I suppose blogging times were different back then. So, now that we’re in a new era,I went back and made some adjustments to the original recipe until I got to my ideal chocolate peanut butter brownie and I’m updating the recipe here for you now.

Still super easy to make and still in a 13×9 pan, which means you’ll end up with 24 chocolate peanut buttery brownies. Which means you can probably share a couple of them and still have enough for yourself.

Oh wait, before we move on, we need to talk about the fact that Reese’s Pieces do not actually have chocolate in them. Does that blow your mind? I realize I brought that up the last time I posted a Reese’s Pieces recipe, but I feel like I need to make this public service announcement again. If you were already aware then carry on, nothing to see here, I’ve just clearly been living under a rock.

Either way, I think there’s enough chocolate in these brownies to excuse the lack of chocolate in Reese’s Pieces.

And now that I’ve adjusted the original recipe, there’s also enough peanut buttery goodness to my liking. Because check out that chocolate. I mean, just look at it. It’s so fudgy and intense that you need a little bit of peanut butter to cut through it.

And obviously the Reese’s Pieces scattered about on top add a little bit of crunch. And more peanut butter brownie balance.

These are totally the kind of brownies you want to bring to a party. Or sell at a bake sale. Or just have in your kitchen at all times so whenever a guest pops in, you can say, “oh, would you like a brownie?” Something tells me you’d start to have guests wayyy more often then you’d like.

But the best part is that these peanut buttery brownies are classic brownies that were delicious in 2009 and are still delicious almost nine years later. And if they’re not still delicious twenty years from now, well then, let’s just say 2038 is not a time I’m looking forward to very much.

Are you always in the mood for chocolate and peanut butter? If not, what do you prefer?

    Tastes pretty good upon first contact, although it needs a lot more bakin time than 30 minutes. At least 45 minutes. We had very very fudgy and drippy brownies after 30 minutes.

    Just made these for my evening master’s class – the guys in there requested something with Reese’s Pieces. These looked fabulous, so I tried them. Will let you know what the verdict was. I think they will love them!

I might suggest that you check out my daughter-in-law-to-be’s (I love saying that) blog, it’s minibaker.com! Happy Baking!

  19. Ellen says:

    whoa! these are amazing. i made two batches in 3 days because my family devoured the first one. they are delicious..so rich and sweet, like eating fudge! if you have an oven like mine, that typically cooks really fast, you may want to put them in for about 30 minutes. the first batch i did for 35. they were still really good but the edges came out a little dark. 30 minutes was perfect for my taste.

  20. Christina says:

    Truly delicious. <3

  21. Kimberly says:

    These are so yummy! My fiancee asks me to make them all the time. The only problem I had was getting the middle to cook evenly with the edges. Sometimes they are just too gooey for my liking. But hey… some people like gooey.

  22. Tyler says:

    These look soo good, I’m gonna have to try them. And if you’re having trouble getting the middle to cook evenly with the edges, you don’t have the right pan. This is what you need: http://www.thinkgeek.com/homeoffice/kitchen/a1aa/

    Mini Reese’s are just what they’re called. Miniature peanut butter cups. They come in small plastic bags. And they don’t have wrappers on them. Really yummy.
