I bought a 12x16x2 magic line pan last night which I guess is considered a half sheet. Of course there was no instruction with it. I asked the girl how much batter and she estimated 4-5 boxes of cake mix saying she likes to fill her about 3/4 way full and they'll overflow allowing her to level. This sounds like a lot of cake mix? Does this sound right? Also should I try to cook at 325 or 350 and approximately how long? Finally will this cook ok without a heating core in the middle? Please help!

Fill pan 1/2 to 2/3, and cook till done.

I use 3 cake mixes for my 12x18x2. Reduce the temp. I recommend baking strips and some folks use the flower nail to help with even baking.

Thanks. Put the flower nail in the batter initially or do you have to let it cook a little? Didn't know if it would fall over in the batter. I do have some baking strips but not sure if mine are long enough, I'll have to look.

tmelrose-put the flower nail in with the pointy end up. I use 2 for a half sheet

I use about 15 cups of batter in my half sheet pan and bake at 325 for 45-55 minutes. I usually have to attach two cake strips end-to-end to gat all the way around the pan.

I calculated 2.5 single cake mixes for a pan that is 16x12x2 inches.

Thank you all. I thought 5 sounded a bit much.
