HI- I am making it right now for a show tonight. My question is I doubled the recipe from 9 oz cake mix to 18 oz. Is it supposed to be pasty like a brownie batter or runny like a cake? Mine turned out pasty like a brownie. It's baking as I speak. did I do something wrong? As I doubled the mix I also doubled the rest of the ingredients. I'm arfraid of how it will turn out- taste and texture wise?? HELP!
