I made it! My first topsy turvy cake! It didnt turn out as expected, but they never do. LOL It also was my first cream cheese pound cake, 10 inch, combined with an 8 inch yoghurt cake. My mom asked me to make it for her retiring colleague who has a cat and plans to start painting again. I wanted to use buttercream for the first time, but as it was quite hot here and we have no a/c I decided to resort to what I know. So the cake got a marzipan cover and plain conf. sugar icing. All accents also are modelled out of marzipan. A big thank you goes to v-rock605 who helped a lot. Thanks for all the tips. Ill definitely try it again (when it isnt so hot anymore).
