In my experience, cakes with strawberrys tend to take longer to thaw. I did a cake last summer for a client that I froze ahead of time, because she was going to be driving it in the car for 3 hours without a cooler (was a 3 tier cake). She said that they still didn't eat the cake for a few hours, so it had been 6+ hours before they atarted to cut. The tier with the strawberries was STILL partially frozen. If I remember sorrectly iit was a 10 or 12 inch round. Hope that helps
