    The marshmallows are not suppose to melt just get soft. After adding marshmallows to top and returning to oven watch carefully, may not need a total of 10 minutes. Don't let the marshmallows brown or the top will be crusty and hard to slice cleanly.  -  02 Feb 2010  (Review from Allrecipes USA and Canada)


    This cake was a total disaster. Marshmallows didn't melt, but formed a crust on top of cake, that made it tough to cut and chew. No one could eat more than one bite.  -  23 Sep 2002  (Review from Allrecipes USA and Canada)
