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.
