    This was so moist and very good- I did add chopped walnuts to the frosting since thats what I know as Rocky Road with the marshmallows and nuts- The cake was and frosting however were fabulous I was skeptical of the vinegar but did use it. I intend to make it again.  -  10 Dec 2001  (Review from Allrecipes USA and Canada)


    MAKE THIS CAKE! It was VERY easy, and the glaze/frosting was simple and came out delicious as well, though sweet, which IMHO, is a good thing. Best cake of this type I've had in a long time. Okay, so I confess I didn't sift anything. I did use a whisk to try and blend the dry ingredients, but I'm no pastry chef, so maybe that is supposed to do something, but the cake was amazing anyway. I plan to use the glaze on other cakes. It set up pretty quickly, and would work on many other cakes. I also think I may double the cake recipe but not the glaze next time, and bake in a 9x13 pan. I think I may also try without the marshmallows. DISCLAIMER: I do not, as a general rule, like chocolate cake. That being said, this one was absolutely delicious! Thanks for the recipe LEESON71!  -  24 Oct 2010  (Review from Allrecipes USA and Canada)


    Fantastic cake!!! I love the idea and it was a big hit with everyone! I doubled the cake recipe and baked it in a 9" tin. I did not need to double the frosting. It melted well and spread easily over the cake. I sprinkled the cake with mini marshmallows, white and chocolate chocolate chips. The topping set nicely and held the topping in place. I will be making this again. It was very easy!!  -  01 Jan 2009  (Review from Allrecipes USA and Canada)
