Peanut Butter Cup Brownie Cake



Peanut butter cup brownie cake, a.k.a. the richest thing I have ever made. 

There's no doubt in my mind, this cake will feed a crowd! Just a small slice will satisfy the biggest chocolate-peanut butter craving. Those of you who have made the homemade version of Reece's peanut butter eggs (popular at Easter-time) may find the recipe for the peanut butter layers very familiar.  

Oh yes, I did.


The brownie layers are very moist and dense, and just a small amount of lightly sweet chocolate frosting holds it all together.



One recommendation? Serve with a tall glass of milk.  Or many.


Peanut Butter Cup Brownie Cake
Yield: One 9-inch cake; serves approximately 25-30

Make this cake for family reunions and large gatherings- it serves many!  It's richness can be cut with a dollop of whipped cream or vanilla ice cream.  You can also half the recipe for the peanut butter layers.
My husband loves a slice of this heated in the microwave with a scoop of ice cream on top. 

Brownie layers:
1 1/2 cups butter
6 ounces unsweetened baker’s chocolate, chopped
3 cups granulated sugar
5 large eggs
1 1/2 teaspoons vanilla extract
1 1/2 cups all-purpose flour
3/4 teaspoon salt
1/2 tsp. baking soda
  1. In a medium saucepan over medium-low heat, melt butter and chocolate; stir until smooth. Transfer to a large bowl and whisk in sugar. Add eggs, one at a time, whisking well after each addition.  Whisk in vanilla, flour, salt and baking soda.
  2. Pour into three greased and floured 9-inch round baking pans. Bake at 350° for 23-25 minutes. Cool for 10 minutes; remove from pan to a wire rack to cool completely.  Wrap in plastic wrap or store in air-tight containers until needed.

 Peanut butter layers:
6 cups powdered sugar
2 cups creamy peanut butter
1/2 cup butter, melted
1/4 cup (maybe more) heavy cream
  1. Mix together the powdered sugar, peanut butter and melted butter in a standing mixer fitted with the paddle attachment.  Mixture will be crumbly.  Add cream 1 tablespoon at a time until the mixture becomes a consistent workable dough.  It should not be crumbly or stick to your fingers.  The mixture should hold together easily when a small amount is squeezed tight in the palm of your hand.
  2. Divide the dough into two even portions.  Spray one (or two if you have them) 9-inch spring-form pans with cooking spray or line two 9-inch pans with parchment rounds.  Press peanut butter dough into the bottom of the pans evenly, forming the peanut butter layers.  Turn the layers out onto two cookie sheets and place in freezer until frozen solid.

Chocolate frosting:
1 1/2 cups butter, softened
1 1/4 cups powdered sugar
1/2 cup unsweetened cocoa powder
2 tsp. vanilla extract
1 tsp. espresso powder
  1. Beat softened butter and powdered sugar together in the bowl of a standing mixer fitted with the whisk attachment.  Scrape down the sides of the bowl and beat again until creamy.  Add cocoa powder and vanilla extract; beat well.  Add espresso powder and beat for 1-2 minutes longer until thoroughly incorporated.
(Note: I use King Arthur espresso powder, but you could substitute finely ground instant coffee)


Assembly:
8 peanut butter cups, each cut in half
3 tsp. chocolate shavings
  1. Remove peanut butter layers from the freezer.  Thinly frost a brownie layer and top with a peanut butter layer; frost peanut butter layer and top with a brownie layer.  Repeat steps until all layers are frosted and stacked.  Thinly frost the entire cake.  Pipe 11 frosting rosettes around the top edge of the cake with a large French piping tip; pipe one rosette in the middle of the cake.  Top each rosette on the outer edge of the cake with a peanut butter cup half.  Place four peanut butter cup halves, fanned, on the middle rosette.  Sprinkle top of cake with chocolate shavings. 
  2. If using the gold sugar, place the cake (on the cake stand or serving platter) in a clean kitchen sink and toss sprinkles onto the sides of the cake.   Sprinkle a little on top of the cake, too. Keep cake covered tightly in plastic wrap to prevent loss of moisture.

    Can I be in love with a cake? Is that possible?

  20. Oh YUMMY! There goes my diet right out the window. I'm going have to walk a few extra miles after eating a slice of this.
    I don't even want to think how many calories there are in just 1 slice.
    Heck with it; enjoy it today and worry about it tomorrow :}

  21. I saw this all over Pinterest today. It looks amazing! Chocolate and peanut butter is a classic combination for a reason :)

  22. Not that I don't love your recipes and photos, but I would've bookmarked this even if I hadn't read beyond the title. The recipe and photos just made it that much more certain that everyone in my household will be undergoing a massive sugar rush for the next, oh, 22 hours or so (assuming the cake lasts that long). Thanks for sharing!

    ReplyDelete
  23. This sounds delicious and looks amazing! I was wondering if the espresso powder in the icing gives it a coffee flavor?

    ReplyDelete
  24. This has to be the most perfect cake I could imagine! Pinning it immediately and making asap. Yum!

    ReplyDelete
  25. Oh my, oh my! This is Heaven on a cake platter! And so beautiful, too. Love it.

  26. Wow, this looks spectacular, and incredibly decadent. It might even give my favorite Doboschtorte recipe a run for most-rich. Though I did send a Doboschtorte in to work once with my husband. An uninitiated coworker cut a regular sized slice, took a bite, and exclaimed "Oh my god, this is good! Really good! (bite) Mmm, it's really rich, though. (bite) Uh, REALLY rich. (bite) I might be sick. (bite) I should probably stop eating this."

    ReplyDelete
  27. I still think your Peanut Butter Cup Caramel Chocolate Cake Cheesecake "takes the cake" if you you don't mind my pun. I made a half-sized version of that using a brownie as the chocolate cake layer and it was TO DIE FOR!!! I didn't make the ganache frosting, I just poured it over the top of the cake once the chocolate mixture had cooled and thickened a bit. I did make the peanut butter frosting and garnished the top with piped swirls of the frosting and topped each with a peanut butter cup. I think I need to make another one now. It was beyond delicious!

    ReplyDelete
  28. Oh my god, I think I just gained about 5 lbs. just looking at this cake. It looks so rich and decadent! It's amazing! :)

  49. Oh my Heather this cake looks amazing! How do you cut such clean slices? I always end up with cake smeared in the frosting no matter how careful I am.

    ReplyDelete
  50. Oh, this sounds wonderful! My Dad loves peanut butter & chocolate, so I'll probably use this for his birthday on August 31st. Thanks for the recipe! :)

    ReplyDelete
  51. I would love to serve this and see people's eyes widen and mouths drop open! An amazing showstopper!

    ReplyDelete
  52. I would like to make this for my anniversary. Would it be possible to make this over the course of two days? I have two little ones and a cake this time consuming just wouldn't be possible lol

    ReplyDelete
  53. Geez, your killing me. I just used your peanut butter frosting recently but this seems like it would even top that...what am I going to do? I need both right now....

    ReplyDelete
  54. Now that is a PERFECT slice of cake! Seriously - how did you get everything so straight and even?!

    ReplyDelete
  55. Oh. My. God. This is killing me right now. I am so upset that I dont have a slice in front of me. Looks DELICIOUS!

    ReplyDelete
  56. Is the cake left to come to room temperature prior to serving? I'm not sure since the layers of peanut butter are frozen. It's just beautiful and looks delicious.....as do all of your recipes.Thanks!

    ReplyDelete
  57. Definitely let it come to room temperature. The peanut butter layers would be way to hard to cut frozen.

    Thanks!

    ReplyDelete
  58. Thanks Heather.....I appreciate your quick reply!

  61. I'm not usually one for chocolate and PB in a dessert other than Reese's, but this looks insane!

    ReplyDelete
  62. wow. like the comment above, this does look insane. it does look maddingly rich. well done.

    ReplyDelete
  63. This is a lovely cake! I made it last weekend for a birthday party with a slight modification. Instead of the chocolate frosting, I made a whipped ganache using semi-sweet chocolate and heavy cream. It was a nice balance with a little less butter :) We had 10 people at the party and I sent everyone home with an additional wedge and we still had a large amount left over! It definitely serves a crowd! The brownie layer was delicious and this will definitely be a go-to recipe for future brownie ventures. I made the layers the day before and frosted it the day of the party and it was perfect! I also used gold fondant powder as decoration since I could not find the gold sugar in time. I dusted it around the cake and the plate and it turned out very pretty! Thanks for this great recipe Heather!

    ReplyDelete
  64. Oh man, this looks good! I bet this would pair great with a port or cabernet. Gotta try it!

    ReplyDelete
  65. JuSt made the cake for my sons 22 birthday. It was amazing!

    ReplyDelete
  66. That would take care of some serious cravings right there! Oh boy, it's going to be hard to get that out of my mind tonight! xo ~Lili

    ReplyDelete
  67. I am currently making this cake, I'm scared as to how we will get through it but then i look at the pictures...i'm sure we'll finish it

    ReplyDelete
  68. After reading that Food Network interview of you, now I just want to make the peanut butter layer and eat it with a spoon.

    ReplyDelete
  69. Only 1 1/4 cups of powdered sugar for the chocolate frosting? Even with the thinnest of layers, I can't get it to cover this cake, let alone have leftovers for the rosettes. I'm making a second batch now, but I'm wondering if the ratios are off.

    ReplyDelete
  70. Oops! Never mind. I was using the paddle attachment instead of the whisk. Important safety tip: never trust your reading and comprehension skills on a Saturday morning. But it turned out delicious both ways!

    ReplyDelete
  71. Thank you for the cake inspiration! I used my own dark chocolate brownie recipe and chocolate frosting, but followed your recipe for the peanut butter layer and added in some crushed peanut butter cups! Mmmm. http://www.secretmarmalade.com/chocolate-peanut-butter-brownie-cake/

    ReplyDelete
  72. Love this idea for a cake! Thank you for the inspiration! I actually followed your recipe for the peanut butter layer and combined it with my son's favorite brownies for my son's birthday cake. I shared both your recipe and my creation on my blog too.

    ReplyDelete
  78. I just love all your recipes!
    I am really looking forward to making this cake for my boyfriends birthday since he just loves chocolate and peanut butter. My only concern is that there is only going to be 6 of us. Is there any way to make a smaller version of this cake? If so, how would you recommend doing it?
    Thank you!

    ReplyDelete
  79. Hi! I just started to make this for Easter weekend...it looks amazing! I'm in the process of making the brownie layers and noticed in the ingredients list, you mention 1 1/2 cups of flour but you don't say when to add it? At what point during the mixing of everything for the brownies does the flour get added in? Do you add it all at once? Thank you!

    ReplyDelete
  80. Nevermind about the flour comment! I swear I read it like 10 times and never noticed the word "flour"! I guess that's what happens when you attempt this first thing in the morning!

    ReplyDelete
  81. Can you make the cake a day in advanced and freeze the whole cake?

    ReplyDelete
  82. Do you think it would work to half the brownie recipe and peanut butter recipe and make it three 8 inch layers?

    ReplyDelete
  83. If you could get two good 8-inch layers if you half the recipe. If you did three the layers may be a little thin but it would still work. You'd just need to reduce the bake time for 3 8-inch layers.

    ReplyDelete
  84. how long do you freeze the peanut butter layers?

    ReplyDelete
  85. Freeze them about two hours or until they are solid.

    ReplyDelete
  86. Thanks Heather. This turned out beautifully, both in looks and taste. I made it for a co-worker's birthday and was able to swipe enough of the ingredients to make a small one for my family. It was a great hit all the way around. Thanks so much for sharing this wonderful recipe. I will be making this on a regular basis.:)

    ReplyDelete
  87. Hi, I read the directions to wrap the cake with plastic wrap (I think you said tightly?) how can I do this and not ruin the look of this beautiful cake?

    Thanks so much,
    Shell

    ReplyDelete
  88. Hi Shell!
    If you let the cake stand at room temperature for a few hours, uncovered, the frosting will crust. The plastic wrap shouldn't stick to the frosting at all. An alternative would be, if you have one of those plastic air-tight cake carries, you could store it in there without fear of marring the appearance.

    Hope this helps!

  89. I made this cake as a Groom's Cake for my son's wedding. I made it as a 13X15 rectangular cake, still 5 layers, to serve 99 in 1/4 by 3 inch pieces. I made a couple trial ones first, to the delight of my coworkers, to learn how to make it work that large. It weighed over 20 lbs! People were just crazy about it. Since the wedding was in Florida (that was an adventure in itself!) and we live in Illinois, we had a large reception here after their honeymoon and arrival at their new home. I made it again, same size, for that reception. I have YOU to thank for all the amazing comments I got about the cake!

  90. Aaahhhh…yeah I’m try this one!!! Looks delicious!!!

  91. Thank you for the recipe for this Bakes Recipe I visit here First time and now book Mark and cannot wait to try this recipe...

  92. A student made me this cake a while back and I haven't been able to forget about it! And now my son (who hates chocolate, oh no!) wanted a peanut butter cup cake for his birthday this week, so I'm using part of this recipe for that. I have the peanut butter layers freezing right now, and I'll use yellow cake with little peanut butter cups mixed in instead, as much as it hurts. What we do for those we love...but you can be sure I'll make it your way when my birthday rolls around! Thanks for sharing!

    ReplyDelete
  93. I made this cake last night for a friend for the weekend..change of plans, we wont see him until next weekend.. is there anyway this cake would last a week in the fridge or freezer? any tips or suggestions?
