When using 2 mixes for should I combine both mixes or prepare them separately? This may be a stupid question but I swear I remember reading somewhere that they shouldn't be combined.

I always mix two mixed together when I need more than 1. Never have any problems.

If it's cake box mixes such as Duncan Hines-I combine 2 boxes sometimes. Seems to have no problems.

Although, I also read here on some posts not to do that. I think that was for scratch cakes. That might be personel preferences. I don't know for sure though.

Good luck!

I've mixed two mixes together before also and have never had a problem.

I mix two mixes together also. Depending on what mixes you are using you may find they tell you how to do it. Duncan Hines puts it inside their box. Sometimes you don't use as much oil or whatever when using two mixes.

However, I have done it without following the inside directions and have not had any problems. I just double what it says on the box.

Did any of that make sense or did I just totally sound like an idiot?

I mix my cake mixes double almost all the time, and it's never seemed to make any difference. I double exactly what it says on the box.

Yes, I meant for box mixed and I have Pillsbury. Yay! I'm going to combine them! Thank you!
