Cheerleader's Filling

Our oldest son Steve went to Shawnee Mission North High School, Susan went one year there and then she and Sally went to Shawnee Mission West. Cindy helped open up Shawnee Mission Northwest. The had a principal with definite ideas about school. He had three semesters instead of two and he had 12 cheerleaders instead of the usual eight. He said that eight thought they were the BEST but 12 would be part of a crowd. Cindy was one of the 12. Before events the cheerleaders would have meals at each other's houses. One cheerleader had a wonderful dessert and when we asked for the recipe she said that she could not share it as it was a family secret. After Cindy graduated from KU Journalism School she went to work as a reporter on the Parson's Sun. One of her projects was editing the annual recipe section. What would turn up but the Cheerleader's filling.
This is it. It is great on Boston Creme Pie or Cake Roll.
