Hey neighbors to the South--have you tried the chocolate chunk cookies at Baby Boomers Cafe in Des Moines? The ones the Obamas love so much? I'm obsessed with these cookies. http://chowhound.chow.com/topics/5883... What do you think of them, and how do they compare to other chocolate chunk cookies you've tried? Are they really really good? Any idea of what the "secret" ingredient (used in only one other of their menu items), is? Guesses so far are espresso powder, brewed coffee, sour cream, extra eggs, oatmeal, and unsual flours.
