I was making the Pioneer Woman's "best chocolate sheet cake ever," and I wasn't paying attention. I just mixed all the dry ingredients together. I promptly realized and started over, but I saved the oopsie dry stuff in a ziplock. What can I do with it? Do you think I can just add wet ingredients and see how it goes? The reason I questioned trying initially and just started over was because of the whole melted butter + cocoa step. So to sum it up, I have a bag with:

2 cups Flour
2 cups Sugar
¼ teaspoons Salt
4 Tablespoons (heaping) Cocoa

Here's her recipe:

p.s. it really is the best chocolate sheet cake EVER.
