Our Coca Cola Cake has been a Southern tradition for generations. A sweet, fudgy, crazy moist cake with thick fudgy icing. Quick and easy to put together!
This is one of those easy, always made from scratch cakes my family grew up eating.
Easy Coca Cola Cake Recipe
This old-fashioned cake recipe is a tried and true classic. My Grandma used to make it for Sunday suppers at her house all the time. Now, I serve it just as often.
It’s great for family dinners, potlucks, church suppers, and neighborhood get-togethers. Everyone loves the incredible, unique texture and the deep chocolate fudge flavor.

What is Coca Cola Cake?
Coca Cola cake is, according to historians, Southern in origin. Whether or not it stems from home kitchens, or simply a Coca-Cola marketing team, there’s no doubt that it’s a staple favorite at many, many family and social gatherings.
Other versions of this cake can be found all over the internet, from the easy Coca Cola cake with cake mix recipes to the Coca Cola cake recipe Southern Living recommends. This is the recipe that has been passed down to me from my Grandma and has been made more times than any of us dare count! Now that leads me to my next point, marshmallows!
Ingredients
Cake:
- Sugar
- All-purpose Flour
- Baking Soda
- Salt
- Coca Cola
- Cocoa
- Unsalted Butter
- Eggs
- Buttermilk
- Vanilla
Glaze:
- Coca Cola
- Unsalted
- Cocoa
- Vanilla
- Confectioners’ Sugar
Tips
- Diet Coca Cola: No. Just a Big No. Don’t do it. This, and all other, cake recipes call for regular Coca-Cola only!
- Buttermilk: Oh, buttermilk. One of those ingredients that you either always have in your fridge, or you never have in your fridge. There is no in-between. If you’re not an avid baker, chances are you definitely do not have buttermilk on hand frequently, if ever. Buttermilk is fantastic for baking, as it adds a very subtle tang along with tenderness to the batters it’s added to.
- In my opinion, there should never be a Coca Cola cake without buttermilk! I highly recommend making sure you grab some for this recipe, but in a pinch, you can use the following substitute:
- Buttermilk Substitute:
- 1 tbsp of white vinegar or lemon juice
- 1 cup milk
- Stir, let stand for 5 minutes
- This recipe will be equal to one cup of buttermilk
- Powdered Sugar: Nobody wants a lumpy glaze on a cake. Sift your powdered sugar. You want it to blend in smoothly to the glaze and avoid white lumps!
- Glaze: This cake is delicious on its own, but when the glaze is added while the cake is still warm, it adds a fudge-tastic topping that completes it.
- Three things are very important in our Coca Cola cake icing instructions:
- Making the glaze while the cake is in the oven.
- Pouring while the cake is still hot.
- Ensuring that the Coca Cola has boiled down to half a cup. If the Coke does not reduce and thicken up, you’ll be left with a glaze that’s too runny and seriously lacking in fudge.
- Three things are very important in our Coca Cola cake icing instructions:
Storing + Freezing + Make-Ahead
- How Long Can You Keep This In The Fridge? This cake can be kept in the fridge for a week.
- Can You Freeze This? This cake can definitely be frozen for 4-6 months. When freezing, be sure that you’ve already frosted the cake while hot. Let it cool, then cover and freeze!
- A side benefit as to why this cake is so amazing is how well the leftovers freeze. The fudgy and oh, so delicious taste remains! Oh darn, I made too much …not!
- Tip: Cut the cake into pieces before you pop it in the freezer. This way, you already have individual slices to let thaw or warm for a few seconds in the microwave.
What Does Southern Coca Cola Cake Taste Like?
Heaven. Next question. Just kidding! Most people assume that Coca-Cola cake would just taste like Coca-Cola. Spoiler alert! It really doesn’t.
The carbonated beverage we’ve all come to know and love has been invited to this party to make the cake moist, airy, and fudgy all at the same time. Honestly, it’s the uniquely moist texture that sets this cake apart from other chocolate sheet cakes.
Texas Sheet Cake would be a good example of a similar chocolate sheet cake. Both have the perfect cake-to-icing ratio in my opinion! Texas sheet cake is a denser, deeper chocolate flavor, while Coco Cola Cake has a medium chocolate intensity, is less dense and cakier, and even more moist.
Recipe Variations
- Soda Switch: Try using root beer or Dr. Pepper in place of the Coca-Cola.
- Cinnamon and Marshmallows: If you’ve perused recipes for a while, you’ll find that many people add cinnamon and mini marshmallows (previously discussed) to their Coca Cola cake. I love both of these ingredients but for me, it’s just not how we grew up enjoying this cake. It’s not how we traditionally made Coca Cola cake.
- Double Up on Chocolate: As I said above, this cake has a lovely, medium chocolate intensity. If you want to make it with a deeper chocolate intensity, here’s how to create a double chocolate Coca Cola cake :
- For the cake:
- Add 1/2 cup cocoa to the cake instead of the 1/4 cup called for.
- For the frosting:
- Boil your Coke down to ¼ a cup instead of a ½.
- Add ¼ a cup of chocolate syrup to make up for the lost pop.
- Reduce your powdered sugar to 3 cups (still sift it well!)
- Add ½ cup cocoa powder instead of 1/4 cup
- For the cake:
- Interested in mega chocolate? Use dark chocolate cocoa powder. Holy. Moly.

My girlfriend always makes this when we have potlucks and picnics to attend and it’s always devoured. My husband wants me to make the topping a coffee flavor. Have you ever made the frosting without the cola, perhaps substituting with coffee instead?
Hi, Laura! I haven’t tried that, but it’s a great idea to use coffee instead, I’m just not sure about the measurements. You can use my icing recipe in my Texas Sheet Cake.
Let us know how it turns out! 🙂
I asked the same question twice lol what I meant to says is the confections sugar 3 3/4 ‘s cups or 3 cups and 3/4th’s cup??
Hi, Gidget! It’s 3 and 3/4th cups. Enjoy baking! 🙂
Thank you I went with the less so my topping was runnier?? But it was so good !!!
Yay! I’m happy you liked it! 🙂
Does the Confectioners sugar mean 3 and 3/4ths cups or 3 and 3/4 cups ??
This recipe didn’t turn out like the photos at all. I followed the recipe to a T, but the cake is very “cakes” and not rich and fudgy like the photo. It domed in the middle too, which makes the frosting all uneven. :(( I am an experienced baker (worked in bakeries for years) so not sure why this recipe looks so different for you versus me!
Hi BPS. Honestly, I can’t imagine what happened to your cake! This is a seriously tried and true recipe that has never come out any way other than pictured. I wish I had an answer for you!! 🙁 Please read some of the other reviews. Folks have been making this recipe for decades.
Kind of late to the party, but this is the exact recipe my husband has been asking for. He’s an ole country boy and remembers his grandmother making this. I’ve tried other versions but something is always “off” with them. I found this version and he tasted it, smiled and said “now that’s my mamaw’s cola cake. 🙂
Woot! Way to go Amy! ? So happy to hear your hubby loved it!
I’m 75 and I’ve been making this cake for decades. It’s one of my favorites. Once I was making it, and I was distracted by something and I forgot to add the cocoa to the icing. I didn’t notice until I poured it on the cake (distracted, remember?). It was still yummy and, occasionally, someone in my family will ask for it that way!
Thanks for all your recipes — yummy!

Hi, Paulla! Thank you! Been there too! I’m so happy it turned out great!
This recipe lacks information.. what stove setting do you use on the liquid part of the cake and the icing? My cake is coming out of the oven and my Coke is just starting to boil. Hope it turns out.
Hi Penny. Thank you for pointing that out. I’ve amended the recipe and add the stove top heat setting. I hope you enjoy the cake <3
I don’t buy soda from the store, would a SodaStream coke work just as well?
He Jo. I don’t use SodaStream so honestly, I’m not sure. I’m sorry! 🙁
This cake was such a great dessert! It had such an amazing texture and it wasn’t too sweet. Will make again, great recipe!
One of my favorite cakes!
Mine too Joanne <3 And it's so darn easy to put together!
Hi made this cake today, is it best served hot or cold, thank you ?
Hey Julie! I love this cake best when it’s served cold <3
