I've never baked anything larger than a 9x13 so I'm a little nervous about mucking this up! A few very dumb, newbie questions:

-how many cups of batter do I need for an 11x15x2 pan?
-do I have to buy a heating core or can I use two flower nails in the centre?
-is 350* okay, or should I bake at 325*?
-should I use bake even strips along with the two flower nails?

Thanks!!

I'm still a newbie so im not sure what the correct method would be, however, when i made the 11x15 I used two flower nails, no bake even strips, and I baked at 350. I think the degrees has more to do with your specific oven though, because from what i understand they vary. Also, i used a recipe that was a cake mix extender,i doubled the recipe and i did have more batter than i needed so i made a couple cupcakes. I hope that's helpful, good luck!

it takes about 11 cups of batter to make the 11x15 more or less depending on how much yours typically rises. i personally always use 2 nails in this pan and also the bake even strips with my oven on 300 degrees. usually takes about an hour and 15 min in my fat daddios pan. hth!

I use Edna De la Cruz's WASC recipe (she has it posted on her website: designmeacake.com). It's the perfect amount for an 11x15. I use two flower nails, no baking strips, and bake at 325 degrees for 1 hour. Has worked flawlessly for me every time, but I offer no guarantees to anyone else!

I just baked one this morning myself- for the second time because the first one broke! bah... so i recommend adding a layer of way paper to the bottom to save yourself any grief. Two flower nails sounds like a good idea- i go without but better safe than sorry!!

Best of luck

oh yes, i second and third the advice to use wax or parchment paper

If only I'd read the advice about parchment paper before baking the cake! I'm just about to go turn it out onto the cooling rack now... wish me luck!!

Success!

Now to tort the dern thing!
