Kat, that is almost verbatim the cake I just made today for S3's 4th birthday (coming up next weekend). It's what my mom calls a "Chocolate Sheath Cake". But I've tried other folks variants which they call a "Texas Sheath Cake."
Man, is it a small world or what? I started reading your list of ingredients, out of curiousity, and just about fell out of my chair!
S3 would like your recipe a little better -- he doesn't like the chopped pecans called for in the icing recipe for my Mom's recipe.
I tried to decorate the cake by putting colored frosting on top. I tried drawing an image of the Transformers character Bumblebee in icing -- not easy at all! I'll try to put some pics up on the alternate universe some time soon.
