6" chocolate cake on 10" white cake. Iced in buttercream w/royal icing decorations. Cake was for an Ariel theme party - so I tried to make the cake look like an undersea castle - complete with seaweed and anemone (one day I'll learn to say it too! LOL). I had the Wilton Castle kit - but there's no way to secure the towers, so I used ice cream cones for the towers, and used the door/windows from the kit since I was running out of time.
