Sweet Potato Chocolate Chip Cookies

Every few months a Penzey's Spices catalog appears in the mail.  I love flipping through them to see what regular folk are cooking and baking in their homes - Penzey's features family recipes with family stories to go along with them.  It's interesting to see how people all over the country cook.  I'll rip out recipes that look good and save them in a haphazard pile in a closet for later.
