Peanut Butter Cookie Dough Brownie Layer Cake

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. 😉

Description

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!


Ingredients

BROWNIES

  • 1 1/2 cup vegetable oil
  • 3 cups sugar
  • 3 tsp vanilla extract
  • 6 eggs
  • 1 1/2 cup flour
  • 1 cup cocoa (I use Hershey’s Special Dark)
  • 3/4 tsp baking powder
  • 1/4 tsp salt

COOKIE DOUGH

  • 1 1/4 cup butter, room temperature
  • 1 1/4 cup dark brown sugar
  • 1/2 cup sugar
  • 3/4 cup peanut butter
  • 3 tsp vanilla extract
  • 2 1/2 cups all purpose flour, heat treated
  • 34 tbsp milk
  • 1 cup semi-sweet chocolate chips

CHOCOLATE GANACHE

  • 12 oz semi-sweet chocolate chips, divided
  • 1 cup heavy whipping cream, divided

PEANUT BUTTER FROSTING

  • 1/4 cup butter
  • 1/4 cup shortening
  • 1/2 cup peanut butter
  • 2 cups powdered sugar
  • 1 tbsp water or milk
  • Mini chocolate chips, for topping, if desired

Instructions

TO MAKE THE BROWNIES:
1. Line the bottoms of three 8 inch cake pans with parchment paper and grease the sides. Preheat oven to 350 degrees.
2. Mix together the oil, sugar and vanilla extract.
3. Add eggs and mix until well combined.
4. Combine flour, cocoa, baking powder and salt.
5. Slowly add to the egg mixture until well combined.
6. Pour the batter evenly into the three pans and spread evenly.
7. Bake for 25-30 minutes, or until a toothpick comes out with a few crumbs.
8. Remove brownies from oven and allow to cool for about 10 minutes in the pan, then remove to cool on wire rack.
9. While brownies cool, make cookie dough.
TO MAKE THE COOKIE DOUGH:
1. Cream butter and sugars together until light and fluffy, about 3-4 minutes.
7. Mix in peanut butter and vanilla extract.
8. With the mixer on low speed, add flour.
9. Add milk to preferred thickness.
10. Stir in chocolate chips. Dough will be thick. Set aside.
TO ASSEMBLE CAKE:
Once the brownies are cool, it’s time to put the layers together. You can pile the cookie dough onto the brownies, stack the layers and leave messy layers, or use the method I used for having clean edges/sides of the cake.
1. Place half of chocolate chips in a metal bowl.
2. Microwave half of the heavy cream until it starts to boil. Remove from microwave and pour over chocolate chips.
3. Cover bowl with saran wrap for 5-7 minutes.
4. Whisk chocolate and cream until smooth.
5. Using one of the same 8 inch cake pans that you baked the brownies in, put parchment paper or saran wrap in the bottom and up the sides of the pan. You will use it to lift the layers out of the pan.
6. Place the first brownie into the bottom of the pan.
7. Add about 3 tbsp of chocolate ganache on top of the brownie and spread into a thin layer. This will help the cookie dough stick to the brownie.
8. Put half of the cookie into the pan and spread evenly on top of the brownie.
9. Remove the first two layers from the cake pan and place on it’s serving dish.
10. Repeat steps 5-8 with the second brownie and remaining cookie dough. Then remove from pan.
11. Put another 3 tbsp of chocolate ganache on top of the cookie dough layer from the first section of cake and spread thinly.
12. Place the second section of cake onto the first.
13. Put another 3 tbsp of chocolate ganache on top of the cookie dough layer on top (the fourth layer) and spread thinly.
14. Top with remaining brownie.
TO FINISH OFF CAKE:
1. Place remaining chocolate chips in a metal bowl.
2. Microwave remaining heavy cream until it starts to boil. Remove from microwave and pour over chocolate chips.
3. Cover bowl with saran wrap for 5-7 minutes.
4. Whisk chocolate and cream until smooth.
5. Allow to sit for a few minutes until it just starts to thicken, then pour over the top of the cake.
6. Place cake in refrigerator and make the peanut butter icing.
7. To make the icing, beat the shortening and butter together until smooth.
8. Add the peanut butter and mix until smooth.
9. Slowly add the powdered sugar and mix until smooth.
10. Add water or milk.
11. Remove cake from fridge, and pipe icing onto the top edge of the cake and sprinkle with mini chocolate chips, if desired.

    I made this yesterday for my cousins Birthday. Everyone will be talking about this cake forever! It was epic and really not that hard for a novice like me. Thanks so much!!!

  2. Marji

    This recipe looks amazing! I want to make it for my son’s birthday party this weekend. Do you think I can make it ahead of time, or is it a “same day” kind of cake? Thanks!

  3. Kay

    what the prep time for this cake?
    what is the Cook time for this cake?
    what is the ready in time for this cake?

    thank you : )

    1. lifeloveandsugar@gmail.com

      I didn’t keep track of times when making it, so I can’t say for sure. The cookie dough isn’t baked, so the cook time is the time for the brownies. All time included is a fair amount – at leave a few hours – given the baking of the brownies, allowing them to cool, making the cookie dough and stacking it all. If you serve it immediately, that reduces some time, but I do refrigerate it first usually.

    We, unfortunately, have a peanut allergy issue in our family. Would the elimination of peanut butter in the cookie dough still leave a good flavor? Can I eliminate the peanut butter from the icing or need to make a different type icing for the cake?

    1. lifeloveandsugar@gmail.com

      Yes, it will still be great without the peanut butter. Just replace the peanut butter with butter in the cookie dough. For the icing, add 1/2 tsp vanilla extract to have a vanilla icing, or about 1/4 cup of cocoa for a chocolate icing.

  5. Anna

    This is a great idea, but way too sweet! Maybe we are just used to darker brownies and less sweet cookies, but unfortunately, it was almost inedible. I felt really bad because I asked for it for my birthday, and my mom spent a lot of time making it, and now we have all this cake that no one wants. I think doing similar, but with your own favorite brownie and chocolate chip cookie dough recipes might be a good hint. Or just use less sugar and more chocolate maybe?

  6. Zara

    Hi! Firstly, this cake is absolutely GORGEOUS! All my favorite things in one dessert; just fab 😉 I had a quick question; I made this cake last night for a dinner I am having tonight, and I did a quick taste test of the cookie dough. Is it supposed to have a rather gritty texture? My brown sugar was soft and moist, and my white sugar didnt have any lumps. Let me know if this is normal; hopefully the whole dessert together tastes just fine! I know cookie dough does tend to be a little gritty, but this just seemed too much. Thanks for the great recipe!

    1. lifeloveandsugar@gmail.com

      Hi Zara! I hope it ended up tasting great! It shouldn’t really be gritty. It’s basically the same cookie dough I use for cookies, minus the eggs and leaveners. It could be that it need to sit a bit and all kind of come together. Did it work out all right?

  7. Josephine Cassar

    Thank you for this ultimately deliscious invention. I did this cake fur my husbands birthday and I cannot stop eating it!!!! (I’m 7 months prego by the way!!!) And you got me addicted to cookie dough!!! I followed your recipe to the letter and it turned out really deliscious. The recipe is very detailed but easy to follow well done!! Will definately try it again for my birthday!!!

  8. Carmen

    Just my two cents:
    I really wanted to make this for my husband’s birthday because it looks sooo delicious! However, the brownies turned out terrible. It obviously may have been something I did but I’m pretty sure I made them right–according to the directions. They didn’t bake well, didn’t hold up at all either, and tasted really weird. My suggestion for those who want to make this is to use a favorite brownie recipe or just chocolate cake.
    Thanks for the recipe–hopefully it will turn out better for me next time!

    1. lifeloveandsugar@gmail.com

      I’m sorry you had a bad experience with the brownies. I’ve made them a number of times and never had trouble. Definitely a box mix would work as well, but you’ll probably need two boxes to get the 3 layers.

      1. Elodie

        I too wanted to bake this cake for my SO’s birthday because it looks amazing! But unfortunately, just as Carmen, the brownies turned out terrible: they didn’t bake properly, didn’t taste good (they tasted mainly like egg with sugar) and were falling apart. I had to throw it away and start again with a brownie recipe I know… I wasn’t sure if I would continue with this recipe or go for something else entirely but finaly chose to stick with it. I hope the end result will be ok!

    2. Melanie

      OMG, I don’t know what happened, but something went terribly wrong????.  I followed the recipe exactly, but the brownies cooked and overflowed in the oven.  Now our house is smoked out:-(. I am so sad because the brownie batter tasted great.  I can only assume the pans were too shallow, so I may have to cut the recipe a bit to account for my pan size.  So sad because the cake looks amazing????????

    1. lifeloveandsugar@gmail.com

      You should be able to see it now. I’m sorry about that, not sure what happened, but it’s fixed.

  9. Courtney

    Where did the recipe go? I thought it was listed in the blog post, but I cannot see it on my computer or my phone?

    1. lifeloveandsugar@gmail.com

      You should be able to see it now. I’m sorry about that, not sure what happened, but it’s fixed.

  10. Amy @ Europe's Calling

    This looks SO delicious! You couldn’t have three better combos than brownies, peanut butter, and cookie dough. I can’t wait to try it:)

    1. lifeloveandsugar@gmail.com

      I’m sorry it’s taken so long for me to respond Elizabeth! We’ve been out of town. I definitely think you could do push pops quite easily. Just bake the brownies and make the cookie dough and then break the brownie into pieces to make the brownie layers and do the same with the cookie dough for those layers. It’d be delicious!

  11. Jenna @ A Savory Feast

    This cake looks too good to be true! My favorite desserts always combine peanut butter and chocolate. This looks amazing!
