I have two sheet cakes to make 12x18. I have never done one!
Do I need to use a flower nail in center? Any suggestions or tips would be appreciated! I saw one recipe that used 2 mixes and baked for 20 mins at 350, does this sound close?? I guess I just do one layer with no filling. and how much do you charge? I usually do shaped and tiered or round cakes. Please help if you can.

Must be a fantastic oven as I couldn't bake that large a cake in 20 mins. using a convection oven..

I am so thankful for your help. no mentioned anything about the nails, do I need to use them for this three mix Wilton 12x18 with baking strips??
