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.

I made this cake ,I never had any trouble with baking a cake ever but this one !I followed it completely step by step ,measured exactly ,I thought it was very easy but when I added the dry ingredients to the wet it was really wet ! I thought mmm this is not going to cook in the allotted time stated! It wasn’t,so kept it cooking for quite a while longer ,until it was .in the end it was cooked in just over an hour and five minutes.looks good ,smells wonderful and chocolatey but timing is definitely wrong! My oven is very good too!! Never had any problems cooking and baking .Will taste good I hope !
The cake is delicious but I had a little trouble with the frosting. It says a 16 oz bag of powdered sugar. Mine was bigger so I just measured out 2 cups (16 oz). I noticed that the powdered sugar didn’t dissolve very well (instructions say put it in after you take it off the heat). It was also very thin. When I poured it on the cake it was still very thin even after cooling completely. Any suggestions?
A 16 oz (this is weight) box of powdered sugar is 3-3/4 cups. 2cups of powdered sugar measured in a measuring cup is not equivalent. Please try this recipe again using either the 16 oz box or measure out 3-3/4 cups. Just finished making this cake and it came out just fine!
Would there need to be any adjustments (like baking time or heat) in order to use this recipe for cupcakes?:)
Thanks!
This is my favorite cake.
I made this today and (admittedly) it’s just for me and my husband so it’ll be around for a few days. How should I store it? In the fridge or is on the counter okay?
It’s a small recipe to my husband guy and I live in a little camper travel train ing and I don’t have a big oven Thailand toaster oven so could I make this in an 8×8 pan
What is challenge butter?
Challenge is a brand name.
