What a darling recipe. I wish we COULD buy Butterfingers for 10¢!!! This is from my Mom's recipe box. I'm not sure I'd do the uncooked eggs though. Here's some info on using eggs safely.
1 angel food cake
4-10¢ butterfingers bars
Cream:
4 egg yolks
2 cups powder sugar
2 t. vanilla
Whip 1 pt. cream & fold in above mixture.
