A cake mix has sugar, baking powder, salt and flavoring already in it. That would make it very hard to use in replace of just the flour in another recipe. If you have a cake mix, make that cake, following the instructions on the package.
Although, you can modify most cake mixes by adding nuts, flavorings, fruit, etc. to it.
There seems to be some misunderstanding. Pillsbury - and other companies - produce chocolate cake mixes, along with chocolate brownie mixes, cookie mixes, and so forth. These mixes include ordinary all purpose or cake flour combined with sugar, cocoa and other ingredients. You use the mix by adding other things, usually eggs, oil or butter, water or milk according to the directions on the package. > But there is not a commercial product that is "chocolate cake flour." Flour is simply flour; cake flour has less gluten (a protein) than all-purpose or bread flour. You need to add cocoa or baking chocolate to the cake flour in order to make chocolate cake.
Yes. Cake mixes have flour and old flour can get "weavells" not sure if spelling correct. These are microscopic tiny black/brown bugs and can be seen in white flour as greyish specs. Ugh!
cake and cookie mixes
Yes, cake mixes are made with wheat flour, and all wheat flour contains gluten. Cake mixes contain less gluten than bread mixes or all-purpose flour, but still enough to cause problems for those who are gluten-sensitive. Betty Crocker has a few gluten-free cake mixes on the market, but in general, you'll need to use scratch recipes that use rice flour, or almond meal. If you do a search for "flourless cake recipes," you'll find a few good ones, though they'll be much more dense than what you get with a boxed mix.
That depends on what kind of cake your baking. . .
No, cake flour is much finer, giving cakes light texture. You would be better of substituting regular all purpose flour
There are cake flours, otherwise all-purpose and unbleached flour is great to use.
Flour
Whole meal can be used in cake baking. But it produces a heaver, less tender cake than white cake flour.
Generally, all-purpose flour is good. You can also use whole wheat -or multigrain flour if you wish.
About 2 boxed cake mixes.
it depends on what company flour, your better off sticking withe the cake flour, your cake might go flat if u us e the wrong type
