Sour Cream Fudge Cake with Creamy Peanut Butter Frosting

Yeah it is.  It’s better than money, that’s how good it is.

And remember back yonder when I whipped up Better Than Robert Redford Cake?  Yeah well this is even better than that! 

No, seriously, you will toss away your Ben Franklin’s, your Euro’s or whatever currency you use for this cake.  Yeah, you will.

I just offered the hooligans $5 for each of their pieces.  And you know what, they wouldn’t take it!  Why?  BECAUSE IT’S BETTER THAN MONEY!

This recipe comes from one of my favorite books, The Cake Book, by Tish Boyle.  If you don’t own this book, think seriously about adding it to your collection.  The recipes are to die for. 

This Sour Cream Fudge Cake with Creamy Peanut Butter Frosting and topped with sugared peanuts is…well there are no words other than, it’s better than money.

This is one of those fudge-like cakes that you make in a regular 9 x 13 pan and either serve it right from there or use a biscuit cutter to cut out cute little circles from the cake pan and pile the frosting high.

And by the way the frosting…Oh Mama…you’ve just never tasted anything so utterly satisfying.  A little of this with black coffee…I don’t even think I’d be able to talk.

Unfortunately there will be no rest in this house until this cakes disappears. 

Let’s make another one together!

Here’s what you will need for the cake: Cake flour, salt, baking soda, unsweetened chocolate, unsalted butter, granulated sugar, eggs vanilla extract, sour cream and hot water.

In a medium bowl sift 2-1/4 cups cake flour, 1-1/2 teaspoons baking soda and 1/2 teaspoon salt.  Set aside.

Also, this is a good time to melt the chocolate.  You want it to be only lukewarm when you add it to the batter so do this early.  You can either melt the 3 ounces of unsweetened chocolate in a double boiler or in the microwave (which is what I did).  If using the microwave stir every 15 seconds until done.  About two minutes.

In the bowl of your electric mixer add 1-1/2 sticks unsalted butter.  Beat for about 1 minute, until creamy.  Slowly add 2-1/4 cups granulated sugar.  Beat for 3 minutes more.  Scrape down the sides of the bowl.  Add 2 teaspoons vanilla extract and beat until incorporated.  Add three eggs, one at a time, mixing well before each addition.

Add half the melted chocolate and beat for one minute.  Add second half of chocolate and beat for another minute or until fully incorporated.  Scrape down the bowl.

On low speed add 1/3 of the flour mixture and beat just until blended.  Don’t over-mix.  Add 1/2 the sour cream until blended.  Continue with another 1/3 of flour and once it’s blended add the other half of the sour cream.  Finish with the last 1/3 of the flour mixture.  Make sure to blend each step just until incorporated.  Do not over blend.

Add 3/4 cup hot water to the mixture but add in three additions.  Blend each addition until fully incorporated.

Pour batter, which will seem more runny than a cake mix batter, into a greased and floured 9 x 13 pan.  Place in a 325 degree oven for 45 to 55 minutes, until a toothpick comes out clean.  Mine took 50 minutes.

When done let cake completely cool.

Let’s make the frosting.  You will need:  Peanut butter, whole milk, unsalted butter, confectioner’s sugar and pure vanilla extract.

In a mixing bowl add 4 Tablespoons unsalted butter and 3/4 cup peanut butter until well blended.  Add 1-1/2 teaspoons vanilla and blend.  Slowly add 3 cups confectioner’s sugar in three additions alternating with 1/3 cup whole milk in two additions.

What you get is an incredible creamy-peanut butter frosting.  If you taste it here you will not be able to stop eating it and there will not be any left for the cake.

Make this frosting after the cake is completely cool or you will have to refrigerate it and bring it back to room temperature to be able to frost the cake.

Go ahead and frost the cake.  Make sure you spread the frosting carefully as the top layer is very delicate due to the fudgey nature of this cake.  I’m telling you it is so good.

Top the cake with some type of sugared peanuts, walnuts or pecans.  Use whatever you like, buy them or make them yourself.  This is what I used.  It adds a great textural change.

I want to make sure you see every fudgey-pothole.

And every glob of frosting.

You just have to try this cake.  You have to.  Don’t you hear its siren song calling you?

Sour Cream Fudge Cake
adapted from The Cake Book by Tish Boyle

2-1/4 cups cake flour
1-1/2 teaspoons baking soda
1/2 teaspoon salt
3 ounces unsweetened chocolate, chopped
1-1/2 sticks unsalted butter, softened
2-1/4 cups granulated sugar
3 large eggs
2 teaspoons vanilla extract
3/4 cup sour cream
3/4 cup hot water

Rack should be placed in the center of the oven and the oven preheated to 325 degrees.  Grease and flour a 9 x 13 baking dish and set aside.

Sift cake flour, baking soda and salt into a medium bowl and set aside.

Melt chopped chocolate in a double boiler or the microwave.  I used the microwave.  It took about 2 minutes, stirring every 15 seconds  Set the chocolate aside until it is lukewarm.

In the bowl of the electric mixer add butter.  Mix for about 1 minute and slowly add granulated sugar.  Beat for about 3 more minutes.  Scrape down the sides of the bowl.  Add vanilla and beat just until incorporated.  Add eggs one at a time.  Beat each egg until fully incorporated into the batter.  Scrape down the bowl.

Add lukewarm, melted chocolate to the mixture in two additions.  Blend until each addition is incorporated.  Add flour-mixture in thirds and alternate with two additions of sour cream.  Blend only until fully incorporated.  Then add hot water in three separate additions as well.  Blend each addition only until it’s  fully incorporated.  Add batter to the prepared pan.

Bake cake for 45 to 55 minutes or until a toothpick comes out clean.  Mine took 50 minuted.

Cool the cake completely before frosting it and adding sugared nuts.

Creamy Peanut Butter Frosting

3/4 cup creamy peanut butter (do not use a natural brand or sugar-free)
4 Tablespoons unsalted butter, softened

1/3 cup whole milk

Mix peanut butter and butter together until fully incorporated.  Add the vanilla extract.  Beat one more minute. 

Alternately add confectioner’s sugar and milk until completely mixed.  Beat at low speed.

Use the frosting right away.

Cake should be stored in the refrigerator after making it.

Enjoy this, I know you will love it.

  39. Deborah 39

  40. Ugh. You hate me. I haven’t had a carb in 7 days.

  41. melly~ 41

    I’m going to have to start putting plastic wrap on the keyboard before clicking your URL.

  59. giz 59

  61. Catt 61

    60 comments later (and 4 Blue Lagoons!!!!) what can i drunkly add?!?! i will make this for my church treats as i usually do from your “dessert” area…
    i read EVERY day!!!!

  62. Laura 62

    I’ve wanted this book (the Tish Boyle cake cookbook) ever since I made a peanut butter pie she contributed to a Lisa Yockelson cookbook I won. It was unbelievable. This looks to be so as well.

    I just found her cookie cookbook used and did a happy dance. :)

  63. Kate 63

    Good God, woman. What are you trying to do to me? I can’t take much more of this!

  64. Oh My, I am just drooling over the pix! It looks yummy! I have filed this recipe under 1st thing to make when I lose 40lbs! Thanks for sharing!

  65. Louise 65

    Oh, this is simply divine! My teen daughter is always looking for a new chocolate recipe, so I’ll toss this her way. Talkin’ money … I just keep the basics in the pantry, and she bakes up a storm. (Although only one of us has to jog 4 miles each morning to keep our girlish figure, hahaha).

  66. Better than money? Definitely. Better than sex? Almost ;)

    You amaze me again dear Noble Pig. That Wild Boar and those hooligans are very lucky!

  67. I hear the “siren song”. Gotta go do some baking!

  68. Melissa 68

    oh my word. I’m going to dream about this. I think I’ll make it to take on vacation so I don’t eat it all myself. WOW.
    (and thanks for the comment on my blog!! Woot woot!!) :)))

  69. Daphne 69

    OMG this looks so good!

  70. Rayrena 70

    Yikes, that sounds so freakin’ good. My stomach is rumbling. Do you have to make the cake? Couldn’t I just frost my fingers?

  71. Oh stop it. How do you keep this pace up girl? And how much does the Wild Boar weigh? You are “money” machine.

  72. Rita 72

    this is better than anything! WOWWWW

  73. You are so bad. Better than money, maybe even better than sex. I didn’t write my wine description; be sure you taste that! It was killer. Girlfriend you might not be able to download a link but will you please tell your fan club to go vote for you! A post like this is why you got nominated in the first place. If it wasn’t 2 am,….

  74. Ok. I think I need the wild boar’s help, here. I just smashed my face into the computer screen trying to get a taste of this. I think I need stitches.

  75. Dee 75

    Must. Have. Now.

  76. dlyn 76

    I have a nervous twitch now that will surely not go away until I try this recipe!

  77. Wendy 77

    Oh. How did you know the Baby Shower was coming up. I was going to go to Costcos and buy a couple of monster pies – but I think I’ll give these a go instead. Also have a Craft Party to go to if I can’t wait. :P Got anything else up your sleeve? Need something awesome for the shower/BBQ. :P Like the mini potatoes (which I am SO making again)… fingery food for people to nibble on.

  78. Indigo 78

    I can’t imagine saying no to $5, but this reflects on me as an extremely cheap person rather than on this cake. Which I think I need to live. Oh, those fudgey potholes…

  79. Wow! That first photo pulled me in. And, they’re better than money too?! I’m sold.

  80. Liz C. 80

    You are seriously going to make me FAT! These look amazing.

  81. Egghead 81

    OK this has me wanting to go make this right now. That fudgy delight will turn my son-in-law into a blithering baby. He loves chocolate cake, especially fudgy and moist. Yummmmm.

  82. I seriously just drooled on myself.

  83. Neen 83

    Oh God. Do you realize how hard it is to read posts like this when I cook only for TWO??????? :)

  84. leslie 84

    Sinful! Drool drool drool!

  85. Kevin 85

    That chcolate cake looks so moist and fudgy and good! And a peanut butter frosting…mmm…

  88. I think I just gained 5 pounds looking at the picture. Can I lick the beaters?

  89. tipper 89

    Now I’m starving.

    Currently have a very popular sour cream chocolate cake that I do, but have never done it with PB!!!

  91. Oh my. I think I love you.

    I have no other words.

  92. Howdy 92

    OMG… would you come live with me… PLEASE!

    As soon as I’m done unpacking and putting away things – which of course will come after we are done doing all the work that needs to be done on this house… I’m going to make me some of this… YUM!

  93. ok ok – so i’m 27 posts behind
    gawd you are PROLIFIC
    but as i was reading my way down, this stopped me dead in my tracks…

    holy moley

    i want this nooooooooooooow

  94. Sarah 94

    Have you ever tried to do cupcakes with this cake recipe? Just wondering if it would work. I might try this weekend…

  95. Aggie 95

    Oh my…my mouth is watering. I love peanut butter anything, and this seems to have it all. Wow. I am going to try this soon!!

    Just found your blog via Picky Palate! I can’t wait to “explore” …

  96. Jill 96

    Oh for crying out loud! I’m getting gastrointestinal pangs just looking at those little bites of heaven–I’d eat a whole freakin’ pan!

  97. Paula 97

    This is a follow up to the comment I left earlier (see #2 above!). I had this post up on the computer because I thought the frosting would be great for my kids to make. Anyway, hubbyman came home unexpectedly at lunch time and saw this on the screen. He got all excited and asked if we were making this today. My daughter said just the frosting part, and hubbyman told her to “get busy” with it! I knew he’d love this! (We have to use gluten free products, so alas we won’t be making the cake portion of your recipe, but we’ll have a go at the frosting!)

  98. Elle 98

    I’m speechless. And drooling.

  99. Looks amazing. I’m almost tempted to venture out in my pj’s in search of some sour cream….

  100. Just put this in my Noble Pig recipe file. it’s true. I’m gonna publish your cookbook – don’t you know ?

    just kidding… but I could…. :)

  101. Peter 101

    I just came.

  102. Emily H 102

    Just made the frosting to put on our favorite boxed brownies…HOLYCOWALMIGHTY!! It is lucious and smooth and peanut-buttery and perfect for anything chocolate. I’m taking it over for Jennyonthespot to try tonite as she is considered the Chocolate/PB Queen of the county!

  103. This cake looks heavenly! It looks incredibly moist and chocolaty. I’ve seen that mix but have never picked it up. I’m going to have to get some!

  104. Laura L. 104

    Okay, I just commented on the Lemon Squares that I tried but on Friday I went out and got the cake flour, sour cream, and baking chocolate to make this. It was a lot more work than I’m used to when baking but it came out awesome. I still have almost a whole cake (it’s just two of us at home and I’m TRYING to be good). My boyfriend asked what the occasion was for baking a cake and I said there was none, I just wanted it. Couldn’t find those peanuts so we did without, but man. So rich and chocolately and delicious. You’re BRILLIANT!!! : )

  105. I am willing to say that a reliable custom writing service supposes to be a light on the way of essay papers writing. Hence, people should utilize it every time they need buy custom essays.

  106. mj 106

    Um, I hardly dare ask, but what happens if I am too lazy to go out and get cake flour, and just attempt this with all-purpise flour?

  107. Noble Pig 107

    Cake flour makes cakes “less dense” as it has the least amount protein.  It’s up to you how you like your cake.

  108. Katherine 108

    can I make this cake into cupcakes??

  109. Noble Pig 109

    You can always try.
