I recently baked some butterballs (aka snowballs) and some thumbprints. Both batches of cookies "melted" and spread all over the cookie sheets, running off the sides onto the bottom of the oven. This happened after they had been in the oven about 5 minutes. I have made these recipes for years and never had a problem. I
have a new oven, but I checked the temperature with an oven thermometer and the temp was what it was supposed to be. Can anyone give me some ideas about what might be happening? I left the dough in the fridge for a few days before I baked them. Could this be the reason? Could it possibly be a problem with the butter? All the butter in both cookies came from the same package.
