This Peanut Butter Cookie Dough Brownie Layer Cake is one decadent, rich dessert! Brownie and peanut butter cookie dough are layered together and topped with chocolate ganache & a touch of peanut butter icing!
If you are a regular reader of my blog, then you know by now that while I love super simple treats, I also have a major love of an over the top dessert! In fact, this dichotomy is indicative of my own personality as well.
Most of the time, I’m a pretty laid back kinda gal. Jeans and a top, hopefully cute, but not trying too hard. I mean really, I just don’t have time for that. I used to. But not these days. And ultimately, I want to be comfy. Not comfy = me in a bad mood.
However, when I’m feeling particularly fabulous or I’m going somewhere that maybe I can get dressed up, I really do love to dress up. Sometimes I wish was like Kate Middleton or something (you know, a princess) and always got to be super cute and have places to dress up for.
But of course, I’m not a princess…
So this cake is basically my dressy side. Monday’s recipe – the Chocolate Chip Cookie Dough Pizza – was my laid back side. It seems fitting that with two posts for cookie dough week, I’d do one for each side. Just so neither side feels left out. 🙂
This cake really isn’t hard to make, despite being dressy. Yes, you have to bake the brownies, but after that it’s smooth sailing.
I used my new favorite brownie recipe, Easy Homemade Brownies From Scratch, rather than using a box mix. Not only do I totally love this brownie, but a single box mix wouldn’t be quite enough for 3 layers. So if you decide you’d rather go the box mix route, you might want to do 2 mixes.
Once the brownies are made, it’s all about the cookie dough. It’s eggless, so totally safe to eat without baking. No worries there.
To hold the layers together, I used a little bit of chocolate ganache. So little, you really can’t tell in the photos that it’s there, but it is. It’s just a little glue to hold all the fun together. 🙂
The method of layering everything together and getting nice, even edges is very similar to the method I use in my Snickers Peanut Butter Brownie Ice Cream Cake. Basically, you layer everything in a cake pan and then lift it out using parchment paper or saran wrap. It might sound confusing, but it’s explained in the directions and is easy peasy and works like a charm.
Of course I thought about just letting this cake go all natural on me. I still think it’d be super cute with rough cookie dough edges. Maybe just use a cookie scoop to add the cookie dough and then stack with the brownies? It’d be beautiful and elegant in it’s own way.
But since this was my “dressy” day, I went with the well kept edges. 😉
I sure hope you have an occasion coming up, because this cake would be perfect!

Hello!
This looks so good and I want to make it this weekend for Father’s Day I just wanted to know, how far in advance can I make the brownie layer? if I put it in Saran Wrap in the fridge would 3-4 days be ok?
We love all things cookie dough and peanut butter so I can’t wait! Thanks 🙂
The brownies can be made a day or two in advance, but I wouldn’t refrigerate them until you actually put the whole cake together. Just keep them in an airtight container. Once you refrigerate brownies (or cake) they start to dry out. Room temperature is better.
I love this recipe and can’t wait to make it! One question though, can you double the butter instead of using shortening in the icing? Or another substitute? Thanks!
i love this recipe! I can’t wait to have a reason to make it. I have one question though, can you substitute Something for the shortening in the icing (maybe double the butter?) ?
Yes, you can replace the shortening with butter. Enjoy it!
Hey there,
Can the brownies be made a couple of days prior?? or are the best baked on the day?
Thanks,
Sheridan.
ps. I just love your blog. 🙂
Yes, they can be made a couple days ahead, just store them in an airtight container. I’m so glad you enjoy the blog! Thank you! 🙂
Hello! So I made this over the weekend to see if I could do it and have it look as good as yours for a baby shower next weekend. My husband apparently isn’t aware that an 8 in pie pan and an 8 in cake pan are different 🙂 So the trial cake isn’t quite as pretty as yours above. But it certainly is tasty. My only regret here is that I didn’t put half of the dough on the first layer (see what happens when you get excited and don’t read all the instructions?) So it isn’t quite even looking. But it is delicious! I will be trying this again with the proper pans and the proper amount of dough on both layers!! Thank you for this! And for those who say the brownie is too sweet – It is kinda sweet but its a brownie! Who wants an unsweet brownie? Anyways thanks again!
P.S. The cookie dough makes a yummy snack for cheat day!
I’m so glad you enjoyed it Renee! Thanks! 🙂
How much is the serving size
It kind of depends on the size of the slices. It’s a pretty rich, tall cake. I’d say it’d make at least 12-16 good sized slices.
I just made this but am worried it will be too sweet, is it really 3 cups sugar for brownie
Yes, the sugar amount is correct. It’s basically a double batch of brownies though. As for if it’s too sweet or not, that’s probably not for me to say. I love things sweet and I know a lot of people have enjoyed this cake. It’d probably be a preference thing. I will say that the cake is rich though. 🙂
I was thinking about making this for a cake auction fundraiser for my daughter’s elementary school. The thing is, we have to drop the cakes off in the morning and they sit out all day until the evening auction (probably 14 hours). Do you think it would hold up? Worried about the cookie dough getting soft and the whole thing sliding apart.
Hmm, the whole thing is pretty dense. I’d like to say that it’d be fine, but I don’t know for sure.
Hi this looks absolutely amazing! Would it be possible to make both, or at least one, of the layers ahead of time and chill for about a day until assembly? Or maybe make the brownies ahead of time but just keep covered until assembly? Also, should cake be served cold/cool/thawed? (I’m in a bit of a time crunch for this one; I apologize for all of the questions!)
You could make the brownies ahead of time and have the cookie dough ready in the fridge. You’ll need to let the dough thaw before you’d be able to press it into the cake. I’d let the whole cake sit out for about 20 minutes to soften a bit before cutting.
def want to try this recipe!
You’ve combined the two things that I ADORE!!!!
Definitely making this later today. I’ve been craving something sweet and I’m not the BIGGEST fan of just regular cake so this is so so so perfect.
Thanks love!
Awesome! I’d love to know how you liked it! 🙂
can i caver this cake with sugarpaste? it seems great!
Gosh, I’m not sure. It’s not a very smooth cake, so it might be kind of lumpy.
You are seriously talented, ma’am! It took me all afternoon to make this wonder myself and now I can’t wait to dig in. Thank you so much for passing it along! 🙂
Thank you so much! I’m so glad you enjoyed it!
This cake is SO delicious! I’ve made it a few times over the last couple months and everyone loves it! I made 2 yesterday. One for a Bday party and one for a Christmas party. I topped them with Reese’s Peanut butter cups since I didn’t have the ingredients for the icing. Big hit!
Thanks so much for posting!
That’s awesome! I’m so glad it’s been a hit! 🙂
Is the brownie batter supposed to be grainy from the sugar?
If I remember correctly, it might’ve been a little grainy at first, but smoothed out as it sat.
Hi! I want to make this for my christmas party and I was wondering how to you put the cookie dough on top of the brownies like you did? I didn’t exactly catch that n the directions? I’m just afraid if I do it my way the brownie will fall apart? Thanks!
You can scoop it onto the brownie and then press it down or smooth it with a spatula. It’s pretty thick.
