      Yield: 42 servings 
  
      3 c  All-purpose flour 
    2/3 c  Unsweetened cocoa powder 
    1/2 ts Baking soda 
      1 c  White sugar 
      1 c  Light brown sugar (packed) 
      1 c  Salted butter (softened) 
      2 lg Eggs 
      2 ts Pure vanilla extract 
      2 c  Mini semisweet choco chips 
      8 oz Mini marshmallows* 
  
  *This recipe slightly modified from the original as noted. 
   
  Preheat oven to 325 (was: 400) degrees F. (was: Until you are ready to 
  assemble the cookies just prior to baking, keep the marshmallows in the 
  freezer--otherwise they will thaw too rapidly -- changed to: Use fresh 
  marshmallows ONLY). 
   
  In medium bown combine flour, cocoa and baking soda.  Set aside. 
   
  Combine sugars in a large bowl.  Using an electric mixer, blend in butter, 
  scraping down the sides of the bowl.  Add eggs and vanilla, and beat at 
  medium speed until light and fluffy. 
   
  Add the flour mixture and chocolate chips, and blend at low speed until 
  combined.  Batter will be very stiff. 
   
  Gather 4-5 (was: frozen) marshmallows in the palm of your hand and cover 
  them with a heaping tablespoonful of dough.  Wrap the dough around the 
  marshmallows, completely encasing them and forming a 2-inch-diameter dough 
  ball. 
   
  Place balls on ungreased baking sheets, 2 inches apart.  Bake 15 (was 
  20-22) minutes.  Cool on pan 2 minutes, then transfer to a cool, flat 
  surface.
