Cream Filling

Directions

1. 1
   To make the cream, place butter and shortening in a mixing bowl, and at low speed, gradually beat in the sugar and vanilla.
2. 2
   Turn the mixer on high and beat for 2-3 minutes until filling is light and fluffy.
3. 3
   To assemble cookies, in a pastry bag with a 1/2 inch, round tip, pipe teaspoon-size blobs of cream into the center of one cookie.
4. 4
   Place another cookie, equal in size to the first, on top of the cream.
5. 5
   Lightly press, to work the filling evenly to the outsides of the cookie.
6. 6
   Continue this process until all the cookies have been sandwiched with cream.
7. 7
   Dunk generously in a large glass of milk.
