ADoes anyone have an updated extender recipe for the 15 oz cake mixes?
get you a scale or you could measure it too --buy two cake mix and use the 18.5 ounces (or whatever it was) add enough to make up the difference -- just seal up the extra and use it for the next time --

I've used this one before, and it works nicely. (From Food.com)
Cake Mix Extender:
3/4 cup flour
1/4 cup sugar
1 teaspoon baking soda
1/2 cup water
1/4 cup oil
Mix all together and add to your already mixed cake mix batter. Bake as usual.
For chocolate cake, I add a heaping tablespoon of cocoa powder. For lemon cake, I replace 1/4 cup of the water with fresh lemon juice.
