I have never traveled with a cake more than an hour and now need to travel 14hrs - Florida to Maryland - in late March with a 2-layer 11x15 sheet cake. We have planned an 80th Surprise Birthday Party for my husbands grandmother, a flower garden theme. My plan is to bake and freeze Tuesday night - stack, fill, and crumbcoat Wednesday night - ice on Thursday evening. We are leaving at 2:00am Friday morning and I was going to do the decorating once we get to Maryland. (I do want to put a stone path textured piece of fondant on before we leave.) The trunk will be full so I was going to put the cake on the floor behind the passenger seat in a box. Am I asking for a disaster with my plan? Shifting, cracking, settling? What problems might I be facing? Any suggestions?

It's just a one tier cake. And small. Just put a good board underneath and you'll be fine.

Agreed... make sure you have a sturdy board under it (more for lifting purposes than anything) and you will be more than fine. I've traveled 4 hours by car and 2.5 hours by ferry with a 4 tiered wedding cake... if that can make it in one piece I think you will be a-okay!

Thank You I feel much better.
