Creating a pastry/cake train- need advice Hi all, I have endeavored to create a train cake/dessert for a 3 year olds birthday party this weekend. My MIL purchased this cake mold and was hoping I could use it to create something great. I am hoping you could advise on the route I should take. Initially, I was planning to just bake cake in each of these, pop them out, and decorate with some buttercream piping. I would then hope to arrange the train on a larger piece of sheet cake and add appropriate decor - train tracks, Oreo-cookie gravel, etc. Upon further thought, I am not confident in cake holding the shape appropriately as I want the train to be very defined. I have been researching pastry techniques (watching Cedric Grolet videos) and thought that maybe I could do a Bavarian cream layered with cake/filling inside and freeze the mold, pop them out, and dip in chocolate- but I’m not sure they will hold their shape and then I also will need to keep them cold.…
