So... I want to make a variation of these cookies
http://www.seriouseats.com/recipes/20... that would add both a cocoa/chocolate flavor and a coffee flavor. However, baking isn't a category of cooking I do much, so I don't have much experience. And I don't eat a lot of sweets and thus don't want to have to do a lot of trial/error experimentation. Can anyone give me a suggested start for adding the ingredients to add these flavors to the recipe?
