London Cake

I made this cake for a woman turning 90 years old.....90!!!! How amazing is that!?  Anyway, one of her sons was planning the whole party and he told me that she was born and raised in London, and he thought it would be great to have a London themed cake.  So I made a two tiered marble cake and my homemade cream cheese frosting for the filling and the outside, and homemade butter cream frosting for the pictures.  I really love how the cake turned out!  I printed out images and put wax paper on top, then with a very small tip, i traced the pictures with the frosting, then put them in the freezer to harden.  Then I simply put the image on the cake and CAREFULLY pull the wax paper off.  I had to fix some of the pictures, but all in all, it turned out awesome!
