I made this cake for my husband's birthday. Whoa Nellie!! Nothing but fabulous. Intense chocolate flavor. Served warm is the only way to eat it too. We both threw our heads back and let out a gasp. Worth 10 billion stars as far as we are concerned. Thanks Nurse Di.

OMGoodness. Yum. The only thing that I would change is there is no way you need all of that frosting. Next time I am halving the frosting recipe. And even then, there will prob be some leftover. But yeah, very most, very chocolatey, very delicious. The family loved it! And it tastes so much better when warm and very easy to reheat. Just cut a slice, put it in some foil, and pop it in the oven at 350 for a few minutes.

delicious beyond words. More like a chocolate spice cake than a buttercream chocolate cake. And better! Agreed - must be eaten warm. Not too rich but chocolately enough for the chocoholics. For the grease and flour step I used cooking spray then dusted the pan with more cocoa. The icing alone is a great recipe, could be used to glaze donuts, candied pecans, etc...This reminds me of church potluck cake, or a Texas sheet cake.
