julia child butter cake

for my brother's birthday i decided to try something challenging (and fun) and make a cake from my new julia childs cookbook. i decided on her basic vanilla cake, with buttercream frosting. however, i had some bananas laying around to i decided to throw those in there, and add some rum to the buttercream - voila, banana fosters cake!

the buttercream though, being a traditional french buttercream, was 90% butter. so putting the cake in the fridge did not work. eating the cake was pretty much like eating a stick of butter. but after letting it sit out and come to room temp, it was pretty darn good.
