This is a great base recipe for adding any extras, like chocolate chips, nuts, dried fruit, etc - it's forgiving. I've made this a million times in a million different ways, and my scrap of a recipe is now covered in dried flecks of batter acquired over the years...so posting for safekeeping and sharing! I always use the mix of brown and white sugar, and my favorites to make are a walnut/golden raisin variety, and a chocolate chip/blueberry variety, just for a few hints. Of course, it's delicious plain as well! Enjoy!
