I have found two different recipes for Neiman Marcus chocolate chip cookies online. There are but slight variations in each, the wild cards are that one recipe calls for instant espresso powder(http://www.neimanmarcus.com/store/se..._recipe.jhtml), and the other calls for ground oatmeal (http://www.recipezaar.com/13325). i just have a few questions: first of all, has anyone made either or both of these cookies and which recipe makes the better cookie? secondly, even if you haven't made either recipe, which would you theorize would be better? and finally, if a recipe calls for 1 cup of butter, i commonly use 1/2 cup of butter flavored shortening and a 1/2 cup of margerine. both neiman marcus recipes online call for butter. so do you think i should stick with real butter, or do you think my usual combination will work just as well?
