    I would definitely fight over the last piece of this cake! The peanut butter frosting is out of this world; especially if you're a peanut butter freak like I am. I baked it in a removable tube pan and I guess because of it, I needed to add about another 20 mins. baking time. I also decreased the amount of confectioners sugar in the frosting from four cups to less than three. It was plenty sweet and absolutely fabulous!  -  05 Mar 2001  (Review from Allrecipes USA and Canada)


    nice cake- not just the regular boring chocolate cake here. I halved the recipie to make a smaller layered cake with the frosting in between layers. but the frosting recipie did not turn out well for me at all. it was not smooth at all, so i had to add a little more milk and some melted chocolate chips to make a usable consistency. other than that, it was a very nice little cake!  -  22 Aug 2006  (Review from Allrecipes USA and Canada)


    I just made this cake for a dinner party and it is delicious! The next time I make this cake, I will only make half of the frosting as this recipe makes a TON of frosting that is far to rich to use all of!  -  03 Oct 2010  (Review from Allrecipes USA and Canada)
