Have you ever baked something and thought... Wow... I nailed this recipe? That was me today. But I don't think I realized that till I ate about half of the cookies. Darn. I wish I could take an iota of credit for the recipe but I followed it step by step from Joy of Baking.
Yep, these are the only ingredients you need. Easy peasy.
3 large egg whites
1/4 tsp cream of tartar
3/4 cup superfine sugar
1/4 tsp vanilla
Follow the Joy of Baking link above... it gives the easiest, but most through directions ever. I did alter it slightly and put four-ish chocolate chips into each bit of batter, because, really, what isn't made a little better by chocolate? Maybe chicken. Or tacos. But that's about it. :)
