Add the ingredients for the cookies to a mixing bowl, and blend on high until a thick dough has formed.
Wet your hands slightly, and form the dough into 16 even sized balls.
Flatten the balls of dough into the round shape of an Oreo, and place on a well greased baking sheet.
Bake for 8 minutes, or until cooked through.
Let the cookies cool to room temperature.
Add the ingredients for the icing to a mixing bowl, and blend on high until smooth and creamy.
Place a dollop of icing on the bottom of one of the cookies and spread out evenly. Top the cookie and icing with the bottom of another cookie to form a filled Oreo.
Repeat step 8 with the remaining cookies and icing until you have made a total of 8 Oreo cookies.
For a darker cookie, replace the regular unsweetened cocoa powder with Hershey's dark cocoa or an unsweetened black cocoa.The butter and cream cheese can be replaced with vegan alternatives to make the cookies dairy-free.
