Help! Can I bake 2 boxed mixes at same time in 10x15 pan?

post #1 of 17
Thread Starter 
I'm making a 10x15 cake with Pillsbury Moist Supreme Classic White cake mix--b-day person wants ALL EGG WHITES icon_rolleyes.gif in his cake!

Wilton's 11x15 pan instructions say it needs 11 cups batter (box mix is 4-6 cups) & bakes at 325 for 35-40 min. (I don't have this pan, just read instructions @ Walmart.)

Sooo my question, is can I mix the 2 boxed mixes at once in my KitchenAid & bake in the 10x15 pan? icon_confused.gif Should I lower oven temp to 325 degrees? (Box says 350 degrees & to bake 9x13 for 32-36 min.)

I'll be baking cake tonight or tomorrow. Thanks for any help. icon_smile.gif

I think you can do it. I would personally fill the pan to within 2 inches of the top, and if there was remaining batter, make cupcakes with it. I have baked what amounted to about a mix and a half in a regular old 9x13 pan.

I'd use just a little less than that... I do 2 cake mixes in my 11 x 15 pan but I don't think the 10 x 15 would hold it without it spilling over.. use the extra to make a few cupcakes icon_smile.gif

I make two box mixes together all the time. I bake my cakes at 325 and for my 9"x13" it usually takes about 45 minutes or so. I usually bake it for a while and then check on it.
Good luck and post a pic when your done,

Definitely lower your temp to 325*. when you fill the pan, just make sure it is no ore than 2/3's full...not sure if it will use all of your batter, but you could always use the batter for another little cake!

Not sure what size KA you have, but I have mixed double batches in a 4qt mixer and triple batches in my 6qt!

I do one regular mix and then add a Jiffy cake mix (the kind that makes one layer) for my 11x15 pan. Fills it nicely without extra. I'l check on it's progress after about 45 min. or so.

Wow, such quick responses! Thanks to you all! icon_smile.gif My KA is a 4-1/2 qt.--I think, at least the bowl is a K45--but it is a 300 watt.

I also mix 2 cake mixes together, but I was told at my cake class to never to use Pillsbury only Dncan Hines or Betty crocker. Never tried Pillsbury, an satisfied w/ duncan hines oh the box inside has a chart on how much batter goes into a cake pan.

Good Luck icon_smile.gif

SUCCESS!!! Thanks again, everyone!!! icon_smile.gif

( I had already baked the cake before I saw I shouldn't use Pillsbury.)

In this case, I used 2 boxes of Pillsbury Moist Supreme Classic White cake mix & 8 egg whites (each box said to use 4 egg whites for pure white cake); mixed according to instructions with the doubled amounts of oil & water & baked in a 10x15x3 pan at 325 degrees for at least 1 hr. (started checking after 40 min.). The batter didn't fill pan 2/3 full, but cake ended up about 2 in. high. I didn't have the insulated wraps to put around the pan, so I wet 2 oversized dishtowels--not terry cloth, but 100% cotton--and pinned them on with safety pins. The cake ended up almost completely level--I barely shaved any off!!! All in all, I would not hesitate to use this method again. This was my first attempt at doubling cake mix.

My brother (his b-day cake) said I should always double the cake mixes & bake it in the bigger pan!!! icon_lol.gif

I'm posting this in case anyone else is wondering how the Pillsbury mix would turn out! thumbs_up.gif

The only mix I use is the Pillsbury, all egg white, mix. I've never had any problem. It's always turned out perfectly. I usually just mix one mix at a time, though. I've got a Pampered Chef 8 cup measuring bowl with a handle and spout and I pour my batter into there to measure how much I've got - I don't trust myself to measure the 2/3 in the pan. If I have to use more than one mix, I'll pour my batter all together in one large bowl and then stir it together, and then pour the batter into my pan.

icon_biggrin.gif Great! I am glad everything came out fine. As for the cake mix even where I get my supplies they sell cakes and also told me that for some reason they don't come out well. Hey I don't know or even tried it so if it works for you more power to you. thumbs_up.gif
Do you have the picture that we may see?

Cakefanatic, I wouldn't have even tried the Pillsbury cake mix if I had seen your post before I baked the cake. I more than likely just got lucky & it was a total fluke. Of course, this cake was only for my brother's b-day, so I would have been forgiven for anything--even a "pancake"! icon_lol.gif It ended up about 2 in. high, and I don't know if that is the height they're supposed to be or not. I don't have the nerve to bake & decorate cakes professionally. I'd be a nervous wreck!!! Still, thanks for the info & I probably wouldn't try Pills. cake mix in any other flavor. I actually prefer Duncan Hines anyway--especially the butter recipe yellow--I just happened to have these mixes & needed 2 mixes for the pan. Oh, yeah, my brother decided he wanted to celebrate his b-day E-A-R-L-Y! so, I didn't have much time to do what I'd decided to put on his cake. icon_rolleyes.gif

As for the pics, sorry, but I didn't have a camera & my brother didn't have any film for his. icon_sad.gif
