This is what you do with the wafer sheets.

Firstly, make Condensed Milk Caramel.

Pour the caramel into a bowl. To this add 1 pound of butter, yes it is a lot, but it has to be the whole pound, the butter should melt.

After the butter is incorporated add crushed nuts - I use walnuts.

Spread onto layers of wafer and when done wrap well and put something very heavy on top of the wafers so that the caramel mixture will mix with the wafer...- this is great I make it often.
