    I used 1 cup butter, 2tsp vanilla, 4 cups confectioner's sugar for the filling and still had a lot of filling leftover. Don't use raw eggs in recipes as it can cause food poisoning.  -  23 Jun 2009  (Review from Allrecipes US | Canada)


    These were good, but I prefer making the Spicy Oatmeal cookie recipe (sans raisins) from this site and making the filling using 1/2 c shortening, 1 regular-sized jar of marshmellow fluff, 1/3 c powdered sugar and 3 tsp of hot water with 1/4 tsp salt dissolved in it. More like the Little Debbie Filling, and doesn't need to be refridgerated!  -  12 May 2010  (Review from Allrecipes US | Canada)


    Very Good! This is just my own little by accident tip. I made these on a hot day and the icing started to melt between the cookies so I put the cookies in the freezer. I wrapped each cookie in saran wrap and froze. So yummy, not too hard and the icing still soft. A yummy treat into a cool treat.  -  23 Oct 2007  (Review from Allrecipes US | Canada)
