Just curious here.....How many cake recipies are you guys mixing to bake a 9 X 13 layer. Even my recipies that produce a good amount of batter (5 cups or so), the layer is still only about and inch and a half or so thick after I level it. I know the Wilton guide says it takes 7 cups. I just had the thought of mixing two recipies only to use part of the second; not to mention that I don't charge much for sheet cakes. Maybe I'm just being picky here....?

I use an extender recipe when I do 13x9, the one where you add a egg, 1 cup flour, 1 cup sugar, 1 cup yogurt or sour cream...

I do the same thing TexasSugar does. Heres is the extender recipe I use. Just another option, especially if you don't have yogurt or sc on hand.

3/4 cup flour
1/4 cup sugar
1 teaspoon baking soda
1/2 cup water
1/4 cup oil
1 egg

Edited: Probably goes without saying, but just remember it will take a little longer to cook through

Are these recipes to extend a boxed cake mix?

Great question. I sometimes used a boxed mix and sometimes scratch recipies.

you can extend any recipe with it.........generally people extend a box mix...but I've used them to extend scratch batters with success too!

I've also just pinched the bag of cake mix and only poured half into my mixing bowl in addition to another whole mix when baking a 9x13. I used to agonize over this all the time.......then I just bought a 8"x12" cake pan that takes exactly 1 batch of batter and solved my own issues LOL

I usually mix 3 mixes together and bake two pans at the same time. So 1 1/2 mix for a 9 x 13.
