    The cake portion of this was very good, moist and with a light chocolate flavor. I would not call it fudgy - the flavor reminds me more of red velvet cake than of a traditional chocolate cake. I used Dr. Pepper, and cut the amount of butter by half; otherwise made as written. (Don't use diet soda - the artificial sweetener is not heat stable!) I did not care for the topping though (which is more of a glaze, not a frosting) - it was WAY too sweet. I made a 9x9 cake and 12 cupcakes; the cake got the topping and the cupcakes were frosted with a "flour icing" recipe, which was much less sweet and complemented the cake better. All in all, pretty good recipe.  -  19 Apr 2008  (Review from Allrecipes US | Canada)


    Unbelievable!! I have had this cake before and wanted to find the recipe. I'm sooooo glad I did. The cake is yummy moist and the marshmellows add such a great consistency. This one's a keeper!!  -  07 Dec 2007  (Review from Allrecipes US | Canada)


    This cake reminds me a lot of Texas Sheet Cake...I think the only true difference is that this one adds coca-cola & marshmallows. I used Saco powdered buttermilk as I only rarely use buttermilk. I just added a couple of tbp. in w/ the dry ingredients & added a 1/2 cup of water when I added the eggs. I didn't much care for the frosting until I had it on the cake & then it was superb. Other than using the Saco buttermilk blend, I made no changes to this recipe. It's a keeper as is!  -  24 May 2006  (Review from Allrecipes US | Canada)
