No bakes do me the same way. I think it has to do with humidity, air pressure, temps....I think no bakes are really sensitive to these things.I have a mystery. When I cook I almost never measure just "eyeball" it. The one exception to that is nobakes. I always meticulously measure each ingredient, even the time I cook by stopwatch. I use the same exact ingredients, the same exact pan and everything but sometimes they come out as soup, sometimes perfection, and sometimes like tonight it makes one big cookie lump before I can even get it out of the pan.
