A moist and delicious chocolate cake made with buttermilk and cocoa powder and topped with a homemade chocolate frosting that’s plenty sweet. The frosting has a little crunch here and there from some toasted pecans. They taste so good with chocolate.
Buttermilk
With buttermilk in the batter and in the frosting, this cake makes good use of Buttermilk. Do you find that you frequently have a carton of Buttermilk at the back of the fridge that’s about to go bad? I almost always seem to.
If you make this cake and still have extra buttermilk try making Old-Fashioned Buttermilk Pie, Buttermilk Pancakes or Buttermilk Parmesan Pork Chops.
This is a simple, old-fashioned cake that is always a winner. It’s basically a Texas Sheet Cake except instead of baking it in the typical jelly roll pan (half sheet pan), I’ve made it in a 9X13-inch pan so that it is a little thicker. Chocolate Buttermilk Cake is both light and insanely rich at the same time. It’s very difficult not to go back for another bite. And another. And another. It will keep calling out your name until every last bit is gone.
One minute, you’ll be swooning over it, professing your love. The next minute you’ll be telling it how much hate it for making you eat too much.
That’s why this cake should only be baked for a potluck or a party where there are boatloads of people and there is no chance there will be any left over.
Fudgy Frosting
The frosting is easily assembled in a saucepan and takes only a few minutes. Still warm when poured on top of the cake, it forms an absolutely irresistible fudgy layer. It’s the frosting that really makes the cake. What’s really nice about it is it just naturally spreads itself out over the cake. You only need a spatula to help even it out a little bit.
That’s my kind of cake frosting. I know there are many people who enjoy the labor intensiveness of frosting a 3-layer cake. But I’m not one of them. By that point all I’m thinking is, I want a piece of this cake. Let’s hurry this up.
Buttermilk Substitute
If you don’t have any buttermilk you can make a buttermilk substitute by placing a tablespoon of lemon juice or white vinegar in a glass measuring glass and filling to the 1 cup line with milk. Stir.
Recipe Tips
That being said, you do need to wait a little while for the frosting to cool and set up before you slice it and take a piece out, or all the frosting will run into that empty spot. Unless you stuff the empty spot with a wad of aluminum foil and tilt the pan ever so slightly to make it harder for the frosting to move in that direction. I’m not saving I’ve done that before.
Use full-fat buttermilk.
The pecans can be left out if you need a nut-free dessert.
Storage
Cake can be kept at room temperature for 4 to 5 days if wrapped well.

This chocolate cake is my new favorite! It has the perfect amount of sweetness and a great texture. My only problem with this cake is that I can’t stop eating it!

Oh my! This is the same cake my great grandmother made. I have her recipe, make it on occasion, our whole family calls it The Mommy Gilla Chocolate Turtle Creek cake. Haha. Her name was Gilla Blanton and she was from Langley, Kentucky. Best cake ever.
This cake is amazing! I cut the sugar in the cake down by a third as it seemed like a lot (we don’t eat sweets much), which was perfect for us – but left the icing as is. My husband declared this his new favourite cake!
This is the best chocolate cake I’ve ever had or made. Thank you!
Going to make real soon
Awesome Chocolate Cake and so easy to make. Thanks for sharing. Cheers Erin
Would this cake rise enough to make in a bunt pan?
I think you could make it in a bundt pan Sherry. Let us know how it turns out if you try it.
Thank you so much! I work in a small school (SW Cornwall, UK) and took this in today as a staff room suprise. It was just to put a tea break smile on faces in the christmas run up mayhem, and I called it ‘Chocolate Tuesday Treat’. Oh, happy staff – they loved it! Next week I’m going to surprise them with your Apple Crisp Coffee Cake!
I use this icing when I make brownies and Crazy cake (they are so delicious) That’s what I’m making today for my Father-in-law 82nd birthday
Hope your Father-in-Law had a wonderful birthday!
Don’t know what I did wrong, but this did not turn out like a “cake” at all……was just dense and thick. No lightness to it at all…….
Old fashioned cakes are dense and immensely more flavorful than any you can buy or make with modern recipes. You did nothing wrong, it’s just different. I grew up on those flavors and when I saw the cake slabs, I thought I was in heaven. Gotta make it soon.
I poured the frosting on the cake about 5 minutes after removing it from the oven. It looks like most of the frosting has disappeared down the sides of the cake. How long do you recommend waiting to pour the frosting after the cake comes out of the oven?
Next time, try pouring the frosting on slowly and pouring it mostly in the center. That way by the time it makes it’s way to the edges, it has cooled down and thickened some.
Although I read this review and did as suggested, pour down slowly in the center, this happened to me too. I don’t know what went wrong. But the cake is so yummy!
have been making this cake fir years, Cut it from a mag–called buttermilk brownies also make it in a 9×13 pan. My children(and now my grands )like the thicker version. If I don’t need the whole cake I freeze the rest take a few pieces when ever you get a craving! !!
Oh wow! I have just made this cake this morning and I have had eaten two pieces already. It is so moist and yummy.
I live alone so as with a lot of recipes I make I half the ingredients for a half size cake as I have with this one. The fact it has turned out so well I will make a full size one next time and give my friend half for her family as I do with a lot of cakes I make , ( stops me eating to much cake) she will love this one.
Like you say , the buttermilk sitting in my fridge was nearly forgotten AGAIN ,so I quickly looked up a recipe with buttermilk in and so glad I found this one.
Thank you for this, definitely a regular favourite in my baking.
Got to stop myself eating anymore until tomorrow now!
It really is a delicious cake isn’t it Janis. I have to give away most of it or I keep going back for another piece. Good idea to make a full cake and take half to your friend next time. I am sure she will appreciate it! 🙂
