Other delicious recipes with buttermilk

I’ve shared some great buttermilk recipes that have been a hit with readers including my Buttermilk Texas Sheet Cake, Homemade Cinnamon Rolls with Buttermilk, and even one of my favorite chicken recipes, Baked Buttermilk Chicken Strips. You really haven’t had good chicken strips until you’ve tried those.

For this buttermilk chocolate cake recipe, both the cake and the frosting start out in a saucepan, which is pretty typical of sheet cakes.

Moist Chocolate Cake

This buttermilk cake recipe is super moist, and that has a lot to do with the ingredients.

What makes a cake moist? Well, there are quite a few ingredients that help keep the moisture in a cake. 

Have you ever eaten dry cake? You go to take a bite and it dries out your mouth and that’s not good. Not good at all. 

Ingredients like buttermilk, eggs, butter, sour cream, vegetable oil, and even applesauce help make a cake moist.

And let’s talk about the frosting. I love the way it cools and crackles on the top. There’s a tee-tiny touch of a crunch and that makes this cake pretty much perfect.

Cubes of butter in a saucepan

Start by adding the butter to the saucepan. Keep the heat on medium.

I cube the butter because it melts faster.

Don’t skimp here and use margarine. Be sure to use the real thing, because it will add so much more flavor to your cake. 

Butter and unsweetened cocoa in a saucepan

Once the butter starts to melt, add the unsweetened cocoa to the saucepan.

And finally, pour the water into the saucepan.

Let the butter melt and stir the ingredients together until they blend well. 

Once the ingredients are melted and mixed well together, take the saucepan off of the burner and set it aside. Let the mixture cool.

Thirdly, you’re going to add the baking soda to the bowl.

Now, add the vanilla extract. Mix everything together well. 

I used Adams Best Vanilla Extract for this recipe. It really added a fantastic flavor to the cake.

You can use this in any recipe that calls for vanilla extract, including pound cake, ice cream, cookies, and so much more.

Once you mix the ingredients, slowly pour the butter mixture into the buttermilk mixture, while mixing the ingredients together. This will help incorporate things together well.

Now, add the sugar, and flour to the mixture and mix until well blended.

I used the sugar that Dixie Crystals sent. It’s a great quality granulated sugar. 

Cake in a Wilton pan

Pour the cake mixture into the cake pan. Bake for about 30-35 minutes or until a cake tester comes out clean. Let the cake cool for at least a half of an hour before frosting it. 

For this recipe, I used the pan that Wilton sent. The backside is decorated with colorful circles and decor. This pan is great for cakes, brownies, cookie bars and more. A 9″ x 13″ pan is the perfect size to hold the cake.

You can use the pan for cookie bars, like the ones here, cakes, brownies, and so much more.

Grab the saucepan and add more butter. Set the heat on medium again.

Once the butter is melted, pour in the buttermilk. 

Yep, buttermilk frosting.

Next, add the unsweetened cocoa. 

Powdered sugar in a saucepan

Add the powdered sugar and vanilla extract and mix everything together. I used a whisk to make sure everything mixed well and made sure I got all of the lumps out. Doesn’t take too much mixing action. 

Chocolate frosting in a saucepan

Let the frosting cool a little bit to thicken. If you’re in a hurry, you can put it in the fridge. You want it to still be pourable consistency, but not so thin that it runs off the side of the cake.

After you allow the frosting to cool for a little bit, pour it on the cake. Let it cool a little longer before cutting.

Hi, I made this cake. The icing went straight to the sides and didn’t thicken up a lot. The center doesn’t have any icing now. What did I do wrong?

Hi Lauren,

Sorry to hear that! It could be a couple of things. Was the cake still hot when you poured the icing on? That could make the frosting run to the sides.

If the cake rises quite a lot in the middle, you can gently cut a little bit of the top off and it will be more level. You can see in the pictures that my cake rose a little bit in the middle. It wasn't too high, so I didn't cut the top off of this one. But, that can help.

Also, If the icing seems thin, you can always add more powdered sugar to help thicken it up and then it won't slide down the sides.

And on the flip side, if your icing gets too thick, you can add a little bit of buttermilk to help thin it out.

I hope that helps!
