I will be doing my first cake with a wire topper next weekend. Would somebody mind telling me if there is a special wire used for cakes or do i use floral wire? Thanks!

This will pretty much answer most of your questions. As you will learn, there are many different methods and suggestions of wires to use. have fun caking!

Hi! Use floral wire but stick it into a straw or a stir stick and then into the cake so that it's food safe. If the wire moves around you can pipe a bit of melted chocolate or put some fondant, etc. into the straw. Good luck!
