Old Fashioned Peanut Butter Cake

Old Fashioned Peanut Butter Cake is a good old Southern potluck staple that’s reached cult status.  The hot peanutty frosting gets poured right onto the warm cake, and the whole thing gets showered with roasted peanuts.   Just divine.

This old fashioned sheet cake is a winner!

In case you’ve ever wondered, the ratio of attempted recipes to those that actually make it onto the blog is about 1 to 1.  That’s to say that for every winner there’s a loser.  Today’s lucky winner is an amazing peanut butter cake that has been taunting me from a magazine clipping on my refrigerator door for months.  I finally tackled it and now I’m a happy girl.

I can’t imagine there are too many of you out there who wouldn’t enjoy this peanut butter cake.  I loved everything about it.  Starting with the cake itself, peanut butter does something wonderful to the texture.   It’s not too sweet, just the way I like it, and very pillowy and moist.

But can we talk about that frosting?

The peanut butter frosting is like peanutty caramel, so good!

If you’ve tried my Brown Sugar Peach Cake or my Pumpkin Praline Cake, you might have an inkling about this one.  The frosting is cooked in a saucepan, and then literally poured right over the cake.  It sets up immediately, almost like fudge or caramel.   You have to work quickly, but your reward is that saucepan with a thin layer of peanut frosting clinging to the sides…Let’s just say I stood there scraping it with a spoon for an embarrassingly looooong time.

The batter for this easy cake gets whisked together right in a saucepan.

The batter is thin enough that you can whisk it up in a saucepan, no mixer needed.  That makes this amazing cake dangerously easy to throw together.

The older this blog gets, the longer my favorites list gets, but I’m looking you straight in the eye when I say this cake is a goodie.  You’ll love it, and it will serve you well if you need an easy dessert to bring anywhere this season.  The 9×13 cake can serve up to 24 people, right out of the pan.  Try it.


Reader Rave ~

“I never bake but I made this for my son’s birthday and my whole family thinks it may be the best cake they ever ate. We are die-hard peanut butter fans so perhaps we are biased-but regardless the cake was divine! The frosting is so good, like a peanut butter caramel.
Thanks for a great recipe!!”  ~Gerry

Old Fashioned Peanut Butter Cake

A good old fashioned peanut butter sheet cake with a crazy good warm frosting!
Course Dessert, Snack
Cuisine American, Southern
Prep Time 25 minutes
Cook Time 40 minutes
Yield 24 servings

Ingredients

  • 2 cups all purpose flour
  • 2 cups granulated sugar
  • 1 tsp baking soda
  • 1 tsp salt
  • 1 stick, or 1/2 cup unsalted butter
  • 1 cup water
  • 1/2 cup peanut butter, not natural
  • 1/2 cup vegetable oil
  • 2 large eggs room temperature
  • 1/2 cup buttermilk room temperature
  • 1 tsp vanilla extract

frosting

  • 1 stick, or 1/2 cup unsalted butter
  • 1/2 cup creamy peanut butter
  • 6 Tbsp buttermilk, you might need a touch more if your frosting is too stiff
  • 1 tsp vanilla extract
  • 3 cups confectioner's sugar sifted

garnish

  • roasted peanuts, about 1/2 cup

Instructions

  • Preheat oven to 350F
  • Spray a 9x13 pan.
  • Whisk together the flour, sugar, baking soda, and salt and set aside.
  • Heat the butter and water in a medium/large saucepan until it comes to a boil. Take off the heat and whisk in the peanut butter and oil until smooth. Let cool for a few minutes, then whisk in the eggs, buttermilk, and vanilla until well blended.
  • Add the dry ingredients to the wet ingredients, and whisk until just combined.
  • Pour the batter into the prepared pan and bake for 40-45 minutes, until the top is golden and a toothpick inserted in the center comes out clean. Set the cake on a cooling rack while you make the frosting.
  • To make the frosting, put the butter, peanut butter, and buttermilk in a saucepan and bring to a full boil. Take off the heat and beat in the vanilla and powdered sugar, adding a cup at a time, until the frosting is smooth. I like to put it back on a gentle heat just to rewarm it, stirring constantly, before pouring over the cake. Note: if your frosting is very stiff and not pourable, add a little bit more buttermilk to thin it out.
  • Pour the hot frosting over the warm cake, working quickly because the frosting sets up immediately. Spread evenly over cake.
  • Garnish with peanuts.

Notes

  • Make it chunky!  Yes, of course, go ahead and use chunky PB for this cake.  I would still use smooth for the frosting, but that's your call.

    Hello Sue,
    Might this yummy recipe be made gluten free without substituting all of the flour with 1:1 GF flour as Lynn did in August? Maybe you have an oat flour, almond flour or some combo recommendation up your sleeve? A thousand thanks!

    I was hesitant to even try a new PB cake/bread recipe. Let me tell you though, I was beyond surprised at how amazing this cake turned out. I doubled the recipe and made one exactly as directed. The second cake, I changed the PB frosting to a chocolate ganache type frosting, topped with nuts :-)

    Best PB cakes ever! I am already receiving requests and it hasn’t even been 24 hours since I baked them! Thanks for the recipes! I look forward to others!

        The frosting was a bit tricky. First attempt and I guess I left on heat too long cause it broke and looked a mess. Threw it out. Second attempt I took it off once it was good and hot, but had not reached a boil. Tastes great, but worried it won’t “set” as it should. I looked at the video, hoping for a visual of how frosting should look when pulled from heat, but the video was truly useless.

    I love this recipe. I had never tried peanut butter cake but my husband has talked about it for years. He could never find one that seemed like the one his late mother use to make. I seen this one and made it and have made it a lot since then. He says it reminds him of the one his mother made and for someone that never had one oh my gosh I’m 45 and where has this been all my life YUMMY and so easy to make. Thanks for the memories for my husband and a new treat for me!!!

    This cake is down right DELICIOUS! I had everything in my pantry to make this today, so no special trips to the grocery store. It was so simple to make… creaming butter and sugar for scratch made cakes can be the pits at times, I was so happy for a change. This reminds me of the peanut butter cake that was served at my childhood school, but this one is so much better. If anyone reading reviews is on the fence about making this cake… Get in the kitchen now and make this cake. You will not be disappointed!
    Thank you for sharing this recipe, it is for sure a keeper in my rotation.

    My father-in-law always referenced “The old fashion” peanut butter cake with peanut butter frosting and how nobody ever made it anymore. I ended up needing to make a cake for a funeral at our small church and this is the cake I made. I made sure he had a piece of it and he gave his approval (as did many other people attending the funeral). So easy to make and the taste is wonderful! I will be making it again, as will many others who now have the recipe!

    It has been a year since I made this cake for the first time for my dads birthday. His birthday was again this week and it is the cake he wanted again! It is called “that famous peanut butter cake” around here….and we ALL know what which cake that is! This cake! Other peanut butter cakes call for half the amount of oil/butter and that may still make a good cake. BUT this cake…this cake is so moist ….gaga goo goo! So good! Insane! So good. I make a peanut butter butter cream with it. I have tried natural peanut butter but the cake requires store bought peanut butter…less oily.

    I just made this cake and it is scary how good it is, not exaggerating. I did not have peanuts so i added salt to the icing and it did the trick. I can not wait to rule the bake sale with this one. It actually makes a smooth, pretty glazed cake with a peanut butter color. The smell in the kitchen is also heavenly.

    Hi, I need to make a 6”, 3 layer “smash cake” and they want a peanut butter cake. This cake looks great, but like other I’ve seen says use a sheet pan. Is there a reason not to use layer cake pans?
    Thank you

          I’m not sure, it depends on how you want to arrange it, maybe you’d put a thin layer between the layers, and then drizzle the rest over the top. You can never go wrong making extra frosting, though, then you won’t get caught short. Remember this sets up really fast.

      June 11, 2019 at 1:57 pm

      I mean that natural peanut butters, the ones that separate and you have to stir them together before using, don’t work as well as a classic homogenized pb like Jiff or Skippy. This is just because of the texture difference.

      Hi Paula …
      I lived in the UK for a few years… this is the substitute chart I used for measuring cups to grams:
      Flour. 1 cup = 140 grms or 5 oz.
      Sugar: 1 cup = 225 grms or 8 oz.
      2 Tablespoons = 25 grms or 1 oz.
      brown sugar: 1 cup = 170 grms or 6 oz.
      Butter: 1 cup = 225 grms or 8 oz.
      2 Tablespoons = 25 grms or 1 oz.

    Excellent cake. Used a half sheet jelly roll pan for potluck lunch. Cake came out thin and held its shape (don’t want a crumbly cake at a potluck) with a nice thin, crackly frosting. Browned the butter for the cake, dry roasted the garnish peanuts a little more and mixed with 1 TB butter to up the decadence factor (although probably overkill), and sprinkled the frosting before it set with Maldon salt. Definite keeper.

    I have to thank you so much for this recipe! The cake is so moist and tasty, it was an easy new favorite for everyone. My friend usually really only eats cake for the icing, but I made her some mini-peanut-butter-cakes for her birthday, and she LOVED them. She told me for the first time in her life, she actually likes a cake more than the icing. She ate a whole mini cake (which, for a mini cake, was honestly pretty big) in one day and wouldn’t even let her husband taste it. Now everytime I see her, she always looks around and gets disappointed when I don’t bring her cake, lol. And my mom ONLY does chocolate, so she got “mad” at me when I made this (I evened the cakes for my friend and shared the cake tops with my family) and she liked it so much. She said to definitely save the recipe.

    I’m a little afraid to make these again in case I do something and they’re not as good as the first time, but this recipe is definitely a winner!

      I halved the recipe to make some mini cakes for my friend’s birthday. I made them in mini circular cake pans and cut them in half for more frosting (as that’s typically the part of a cake my friend likes best) and it worked fine, but I’m sure the cakes being smaller made the cutting and stacking a little bit easier.

Couldn’t even wait for the cake to cool to try some. It’s great warm. Can’t wait to see what it taste like at room temp. tomorrow. I did use half brown sugar and half white sugar and I also used milk instead of the water. Love it!

I tried turning some of the left over pieces (can’t believe we still have leftovers) into a “Reese’s Cake” by adding chocolate ganache on top of the peanut butter frosting and then chopped Reese’s cups on top. Woah! Delicious! Both the original and the souped up version are winners!

    I made this cake today. It might be the best thing I have ever baked. To those who asked about making cupcakes, something came up, so I made the frosting while the cake baked. The cake and frosting cooled for 45 minutes. I rebeat the cooled frosting a bit to loosen it up. It was a good consistency for cupcakes at that point. This cake is special. Thank you so much for sharing it with us.

    I made the peanut butter cake last night. It is very moist even this morning! I used crunchy peanut cake for batter. The icing tastes just like peanut butter fudge my grandmother made from a cookbook complied by N Y herald Tribune in 1930’s. Also I chopped the peanuts that I put over the icing.

    I made this cake yesterday (recipe as is) and it was too sweet that no one in my family could handle it. So I tried it again today and changed some things… I cut the sugar by half, and also used brown sugar and white sugar mixed…so 1/2 cup brown sugar and 1/2 cup white sugar. Instead of 1 cup water, I used 1 cup regular milk which seems like a no brainer to me, but I don’t know all the rules of baking, as I’m just learning by kinda teaching myself) but the idea of putting water in a cake mix does sound as good as milk does so I gave it a try. And by the way, I looked up many peanut butter cake recipes and it seems that most of them use water, I don’t understand why… I just don’t get it, but anyway, I used milk and it turned out great! Also, just for fun I threw in 2 packages of instant oatmeal, and last I skipped the icing altogether because that was ridiculously sweet it just made me feel sick. Instead I used a cinnamon brown sugar crumb topping and that was the perfect touch…not too sweet and a little crunch on top. Thank you for your recipe, it was a great base for me to fine tune to my family’s liking.

      This particular cake has a thin batter, and the water helps balance out the thick peanut butter. The balance is just right, so I’d stick with the water and not substitute oil or buttermilk.

    I am writing this review because this cake is very good as is! If you change nothing, you Wil be happy! However, after a few test runs (3), I realize a few minor changes make the cake *subjectively* better.
    I made this cake for my dad’s 66th birthday. I made 3 “very very mini” test batches in the days before. The moistest cake was achieved with all brown sugar, heaping measurements of peanut butter and flipping the amounts of water and buttermilk. The flour was measured with the “spoon and sweep method”.
    The cake was removed from the oven when a fork inserted in the center was moist (not dough, but moisture). I then put the whole cake in the freezer immediately to cool it down completely, about an hour. Anyway, the cake is moist and while the peanut butter flavor is mild, the cake wa’ll is perfect paired with peanut butter buttercream. Yum!

    This is the second best cake that I have ever eaten. The best is a 5 ingredient chocolate flourless cake. I left off the peanuts but thought that peanuts would be good in the frosting. I was thinking that adding chopped peanuts in the frosting would be good, but then ,I thought that the saltiness of the peanuts on the top when sprinkled on top would be a great surprise for the palate. This cake recipe is definately a keeper.

I did take a cue from others who suggested cutting back on the sugar. I used 1 and 1/2 cups and it is still very sweet.

The result was a moist, soft and utterly delicious cake even though I’m not really a big PB fan. Reduced the sugar by half and omitted the frosting, and am very pleased with the result. In fact, the sweetness was just perfect for me and my family after reducing the sugar.

    Thank you!

    Why no natural PB? Does it effect the finished cake? Is it OK to use for the icing? Thanks!!

      I only avoid the natural pb because it tends to be more oily than the regular, and is a bit more unreliable in baking, but you can use it if you like.

    I just tried this recipe! So yummy! Very moist and fluffy. It’s very hard to find buttermilk in Brazil, specially where I live. So I used regular whole milk yogurt instead to make the batter. I did not make the frosting because I like naked cakes better. Thank you for sharing this amazing recipe. It’s now part of my family’s recipe book. Abraços!

    Hands down, this is the BEST bake that I have ever made! Perfect balance of salty sweet crunchy buttery… Recipe is also very forgiving. I am British and got confused about cups/sticks as I prefer metric, and I have even made it quite successfully using almost twice as much butter as I am supposed to. I bake for a small cafe and this bake is always one of the fastest to sell out. Thank you so much Sue!

        You can make the cake in round pans, but the frosting would be tricky because it’s pourable, and then hardens as it sits on the cake, so I’m not sure how that would work on a layer cake. You might look up a different peanut butter frosting for your cake, Leigh.

    Very yummy cake and smells terrific cooking. I’ve made this twice. Both times the batter was very runny and I had to bake longer to get it done and still seemed somewhat undercooked .There is a very high liquid to solid ratio for a cake. Next time I am going to reduce the water and see if that helps without affecting the moistness. The cooked icing is 5 star!

    There’s a note with the buttermilk in the cake ingredients advising that you may need a touch more if your “frosting” is too stiff. Should this note be with the frosting, and not the cake ingredients?

    I made this cake today for a 4th of July party and it had great reviews! I made it in a cookie sheet with sides like a sheet cake. I think I’ll adjust the measurements a little to make more batter for both the cake and the frosting. Any suggestions if you’ve already done that? What would you say is the cook time. I did 35 min and it was too long.
