Chocolate Coca-Cola Cake

This was very good. The icing kind of melts into the cake, so I think next time I'll make the recipe as indicated, then make another batch of icing and spread it over the cake when cool. Usually homemade cakes are dry, but this was incredibly moist. I used a can of regular Coke.

I made this cake for an informal buffet at our home. It was a rave hit with lots of recipe requests. I normally make my carrot cake which is also well received, but decided to try this after eating it in a Charleston restaurant. And yes, the marshmallows do rise to the top.

If I used regular-sized marshmallows instead of mini, how many should I substitute for? Thank you.
