1 pkg. Devil's Food cake mix
1/2 C butter, softened
Preheat oven to 350.
Combine ingredients until thoroughly moistened and it forms a dough.
Drop in rounded teaspoonfuls (these really are small) two inches apart on an ungreased cookie sheets.
Bake for 8-11 minutes and then remove and let them cool on a wire rack.
1 box powdered sugar
2/3-1 cube of softened butter (or 1/2 butter, 1/2 cream cheese)
2-3 tsp vanilla
1/2 C warm milk
dash of salt
Put powdered sugar, butter, salt and vanilla in mixing bowl.
Mix with a hand mixer (it makes it smoother) while gradually adding milk until the consistency is as thick or thin as you want it (you probably won't use all the milk). For oreos it should be thicker.
When the cookies are completely cooled, frost and make sandwiches.
