  8. Hello i cannot find cake mix in our place can i use cake flour, all purpose flour? If so how many cups in one batch…thank you

    1. A cake mix has the flour, sugar and a levening like baking soda already mixed together. So just using all purpose flour wouldn’t give you the same results unfortunately. Here is a link to some cake mixes on Amazon if you want to order one.
