One of the most favorite cookies of all time was invented (accidentally) by Ruth Wakefield, an innkeeper.  She was baking Butter Drop Do cookies one day, using a recipe that dated back to colonial times. Wanting chocolate cookies, she cut up a Nestlé chocolate bar and put the chunks in the batter. When she took them out of the oven, she expected to find chocolate-flavored cookies. Instead, what she got were butter cookies with gooey chocolate chips. Aren’t we glad that happened?
