Chocolate Peanut Butter Brownies (gluten-free, 100% whole grain)
These healthier chocolate peanut butter brownies use ground up oats in place of flour, making them gluten-free and 100% whole grain!

I love how intensely chocolaty these are. The chocolate chips certainly adds to that! But the peanut butter topping is also pretty awesome. Too often, you mix cocoa-based goodies with peanut butter in a batter and the peanut butter is totally overshadowed. In these chocolate peanut butter brownies, you have a nice, gooey layer of peanut butter right up top.

One thing to note is that I used an awkward-sized pan that was slightly smaller than 8″x8″, meaning the brownies in the pictures are slightly thicker than yours will be.

Oh my goodness – those look ridiculous. I'm amazed they're healthy. Need to make these for sure. Your pics look too good not to try them!
Thank you! I hope you'll like them. :)
I am so excited; I can make these, and not have to buy special flours!! I am definitely under baking them, just in case you were curious.
Oh! I didn't even realize that. I should have pointed that out myself. So thanks for doing that. :)
Erin, these look AMAZING!!!!!!! Wow. Wow. Wow.
Thank you! :)
You will never hear me complain about the addition of chocolate chips. Oh my, I'm drooling over these. Rationing them out was probably a wise decision.
Perhaps wise, but a difficult decision! So much more fun to just shove them all in my face at once. :)
I like a fudgy brownie and I think this would fit the bill quite nicely;-)
Yup! It's pretty much just goo. :)
Look at those brownies, so gooey and amazing.
You are killing me with this recipe! The brownie looks absolutely incredible….sooo gooey and rich! Yummy!
Oh yeah. These are very rich. And very dark. I forgot to mention that!
This one looks as though you are left licking your fingers. Peanut butter, yum!
Haha, you can even see my fingerprints in one!
Oh, these brownies look beyond fudgy! I would love to have several with my morning coffee.
p.s. Thanks for under-baking them (and testing!). :D
Oh, you're welcome. It is my duty, isn't it? ;)
I have been exercising all week. I avoided sweets all week. And now this?!? How can I resist?!?! :D
Eduarda Castro
Haha, hey Eduarda. Sorry again! Make 1/2 the batch! It'll be enough. :)
Gluten free?! I'm always looking for a good GF recipe for friends and to make my Father-in-law! I can't wait to try this one and the pictures are PHENOM!
Thank you! :) And I'm happy to help you out with your GF needs! Luckily you just need some non-contaminated oats and you'll be set. :)
I am alllll over this!! Yum!
My neighbor's daughter just found out that she has to avoid gluten products and I've been searching for something gluten free. This is the first recipe that I've seen worth trying. I love Sally's Baking Addiction too so that seals the deal that these are a "must make"!
Oh, you've come to the right place! Have you tried the chickpea cookies? Or rather the grain-free chocolate chip peanut butter cookie dough bites? They're GF and quite healthy. :) I hope you'll like them! (the chickpea cookies or brownies :))
OMG…. Want!! I am just thinking that the yogurt in these makes them healthy, right? So no guilt :)
Well, OBVIOUSLY! :D They're basically health food. Yup.
Looks like a dream of chocolate and PB! If these make it into my dreams tonight a good start to the weekend is basically guaranteed!
Hehe. I hope they made it! Sorry you don't have an oven to try these out. I would go crazy if I were you, looking at all these food blogs. I have no idea how you do it!
Girl, you had me at brownie. Then you threw in peanut butter, gluten free, AND THOSE PICTURES!? Gimme, now.
Haha. Why, thank you. Love your enthusiasm. :)
Kind of gushing over these! My weakness is undercooked brownies. I always leave mine a dad fudgy/raw.
Yeah, you know how it's done! Isn't raw stuff supposed to be healthy, anyway? ;)
Addition of chocolate chips sounds great. I'm trying to reduce amount of sugar in my baked goods as well, so it's interesting. And what did you mean by awkward sized pan? BBTW, your brownies look amazing!
Thank you! And the pan was a weird sized pan I got here in Germany. It was smaller than an 8×8. I hope you're enjoying SF! :)
These are the best thing I've seen all day! Love that you added the chocolate chips, I just wish I had one of these beauties in front of me :).
Wow, thanks! I wish I had you here to share them with you. The husband hated them (he hates everything with natural peanut butter ;)) so I was eating these for a looong time!
Oh my! Erin this looks fabulous!
Thanks, Katrina!
