Boring Meeting Pumpkin Cookies

"These wonderful cookies were brought to our boring Faculty Senate meetings at school by Brianna, a 7th grade English teacher. All the teachers were instantly addicted! So moist and yummy. She also had a vanilla icing that went on top---with these ingredients---powdered sugar, butter, milk and vanilla extract. The only problem is that she never measured the ingredients for the icing--just whipped it up--as I do--so you'll have to kind of guess for yourself how much of each ingredient--all she told me was you need lots of powdered sugar and butter and just a little milk and vanilla extract. Good luck! (But even if you don't get the icing to turn out--the cookies themselves are out of this world!) The serving size may be off--I can't quite remember how much the recipe makes."
