I am helping a friend make her daughters bday cake for next thusday...we will not be baking til this monday.

I have baked 8 inch rounds (there will be two of those), but I have never baked a 10" round (there will be two of those as well). I only have 1 10" pan....we will be using box cake mix

Soooo....on baking a 10" round, what is your advice on the following:

how full should the pan be
what temp
how long to bake (I have several flower nails and a heating core)

TIA

Wow! a 10 foot round that's huge! just joking, (sorry couldn't help it, the typos struck me as funny).

Fill pans with 6 cups of batter.
Bake at 325.
Start checking after 30 minutes (time depends on the cake recipe used).

lol....i notice the 10' typo too!!! that would be quite ambitious LOL....I fixed it....its a 10 INCH round

I don't use a flower nail on my 10" cakes but i guess you could use one.

I use the flower nail in mine. I even use it in smaller cakes. One cake mix will usually be enough for a 2" deep round 10" pan.

In 40 years of baking I've never used a flower nail for baking. Never.

Fill about half full - I use a 10" round that is 3" deep so that took about 1.5 mixes - the rest is in the freezer. I used a flower nail as a core and my homemade baking strips (just cut from remnant fleece). Following others recommendation - I baked this at 325 degrees. Since this is a deep pan and I used the strips, it took about 75 min to bake, but was flat, level and perfect.

I, too, never use a flower nail/heating core. I bake my cakes at 325 for a longer time. a 10" pan would probably be in a for a total of 75-80 minutes. But I would check it at 65 and decide from there how long it needs.

No flower nail here either. 325 till it is done, I fill a tad more than 2/3 full, I like for it to make sure it fills the pan when it is done.

- I've never used flower nails or heating cores no matter how big the cake is.
- In a home kitchen, I bake at 325.
- I never use a timer, so the best I can say is "bake it until it's done".
- One mix for a 10" round pan.
- I grease only, no flour. Cakes rise higher for me.

Shouldn't really need a heat core unless it is a 3in cake. I don't use a timer....bake until it springs back and smells done. When I baked at home...I would say....bake it untill you smell it in my living room!! lol
If you are really worried about it...bake a test cake and it you love the results, throw it in the freezer.
Happy Baking!
