I didn’t have high expectations for a cake laced with soda pop. But this Classic Coca Cola Cake with Marshmallows was moist, scrumptious and beloved by all who were lucky enough to get a slice.

Classic Coca Cola Cake with Marshmallows

I had a vague recollection of seeing this classic Coca Cola Cake Recipe once upon a time, but it sounded a bit odd. As a former Diet Coke addict, I can understand the appeal of an icy cold cola. But in a cake? When my hairstylist raved about this cake (he and I both have a huge fondness for Jacques Torres’ Chocolate Chip Cookies), I took notice.

We had Coke in the fridge (the high octane regular version, not diet) and mini-marshmallows on hand. I had no excuse not to give this Coke Cake a try. Note the color differentiation in that forkful—the top is where those marshmallows melted into the batter. This Coca Cola Cake with marshmallows one exceptionally moist, irresistible cake!

How to Make a Coca Cola Cake Recipe

I had a feeling that my chocoholic family would give it their approval, but this one exceeded my expectations.

  • I made the recipe pretty much as written except that I sprinkled the marshmallows over the batter and smoothed them into the top of the batter using an offset spatula. A couple of reviews (this same recipe can be found all over the Internet) mentioned the cake was ugly due to the lumpy marshmallows, so I did my best to make it a little more attractive. If your frosting ends up looking a little bumpy (mine did!), garnishing each slice will help refocus the attention off of any imperfections.
  • If you want a perfectly smooth glaze, just skip the mini marshmallows. This Coke Cake will still be super moist and delicious without them!
  • I omitted the sprinkling of pecans over the frosting so my family wouldn’t snub it. But if you are a fan of nuts in your desserts, add some chopped pecans to the frosting before it sets.

They went nuts for this easy coca-cola cake(despite the lack of said nuts), as did my girlfriends who were over for lunch the next day. Not heavy on chocolate, even the picky daughter ate her fair share. It’s super tender, moist and delicious!! I think your family will adore this classic Coca Cola Cake with marshmallows as much as mine did.

  5. Now you have got me wanting to go get a bottle of coke to try this out. It looks really moist and divine! 🙂

  6. I’ve tried a coca-cola cake before – 4 years ago- but my version was without the marshmallows. It was really good very moist and delish. Thanks for reminding me :)… your cake looks so perfect.

  7. That looks like a super sweet cake with the coke and all the sugar. I’ve never been a pop drinker so we only ever have ginger ale in the house for upset tummies. I’ve seen coca cola used in quite a few recipes but never in cake! Good for you for trying it and making it so lovely!

  8. Liz, I have always wanted to try a coca cola cake!!!! I need to make this! I’m so curious about the taste and this cake looks delicious!!!!

  9. How funny I posted coke cupcakes today!

  10. I’ve always wanted to give the coca cola chocolate recipe a try but have been skeptical about it. Good to know it’s worth trying, I’ll have to give it a go!

  11. You amaze me every time Liz ! I never understood from a Coke cake ! This one looks terrific and it’s a nice deal for the coca cola addicts !

  12. I absolutely adore coke cake! One of the things that I love about this cake is that it keeps getting better and better because it caramelizes over a day or two and is actually better two days after (if it lasts that long)!

  13. Lizzy ! Always I heard about a coca cola cake and always all the people say is amazing!

  16. I have seen this recipe but honestly didn’t pay much attention, but you have convinced me to try it Liz. We love a moist chocolate cake and that fantastic poured on frosting.

  17. The cake looks surprisingly moist and tempting that I even want to give it a try!

  18. That looks fantastic Liz, so moist. Looks like you had great restraint. I think I might have had a hard time taking pictures without helping myself.

  19. Looks lovely and moist! Hard to resist!

  20. Coco cola in both the frosting and the cake? Oh…this has got to be good! What a lovely cake and one that this coke lover would love!

  21. Sounds yummy. I do believe I have seen this recipe around the web too.

  22. Recipes made with soda always boggle my mind, but I always end up loving them! This looks so scrumptious!

  23. Coca-Cola Cake just sounds fun! I will give this a try, I’m sure the guys will love it. Thanks for the tips on the marshmallows.

  24. I remember this cake and it was a good one! Can’t wait to try!

  25. I have heard about this cake but have never tried it! It looks like it’s totally worth a try!

  26. Now I am intrigued…If the elegant gourmet at TSCCB (and fellow diet Coke fan) says thumbs up to Coca-Cola and marshmallows; well, I’m game to take the Coke Cake challenge!

  27. I’ve heard of a coco cola cake and have always wanted to try it. Yours looks perfect, Liz! So chocolaty and delicious! I can’t wait to try this!

  28. I think this is the first time I hear of a coca cola cake.
    I love drinking cola, and it does sound strange to add it into a cake, but very intriguing and your cake looks amazing!

  29. This is one of those cakes that I have seen around but never dared to give it a go. Yours certainly is attractive, I may just be tempted to head out and buy some coca cola!

  30. Lizzy,
    I’ve never made coca cola cake. It certainly looks delicious. I don’t usually have mini marshmallows on hand but maybe I could cut up the large ones.

  31. I too have heard of this before but never tried it. No doubt it would be big hit with my dessert lovers. Your perfectly cut serving is gorgeous!

  32. Wow! That’s the first I’ve heard of coca cola cake, Liz. Although I’ve made coca cola macarons I’d never thought of making a cake with it. Tell me, is the cocoa powder more for the colouring or does it help to highlight the coke flavour? I’m intrigued. Love how there are squelchy marshmallows in there too!

  33. I have been making this cake for a considerable length of time and its one of my top picks. I add slashed pecans to the icing. It’s yummy!

  34. Liz I haven’t had this cake since the 70s. I recall it being a huge hit then. How fun to recreate it. I love it and will have to make it for my kids. Thanks for bringing me back down memory lane. Wish my dad was here to sample it – he loved it!

  35. I’ve eaten this Coca Cola cake since 1967, and have loved it right from my very first bite. My mother-in-law baked it, and no matter how many times I begged for her recipe, she never shared. She knew her recipe was Chocolate Gold.  She passed away a few years ago, and I haven’t had her cake since – until yesterday, when I found your recipe. I baked it and shared it with my family, who also loved “Grandma’s Coca Cola Cake.   They all asked for a second slice, and said that it tasted just like hers. For those of you who are skeptical, just try it once. I guarantee you’ll be baking it the rest of your life, and whomever tastes it will be begging you to bake it again!  This cake’s like Spaghetti Sauce in that the longer it sits the better it tastes. I had a slice today (the 2nd day after baking) and it was even better than yesterday.  I’m so glad I finally found this recipe. The only thing I did differently was use one 12 oz can EACH for the cake and the frosting. And be sure you apply the frosting on a HOT cake. It makes a difference.
