I am making the Oatmeal- Spice Cookies from the Sept 97 issue. I followed the recipe except for the brown sugar. Since I was out I looked up the substitute and it told me to replace it with regular sugar and 3 tablespoons Molasses. I did that and baked the first batch and they came out horrible. They are suppoed to be thick and chewy and mine are thin and rock hard. Can I safe my batter or should I just toss it?

Thanks
Martina
