Another one of Nana's OLD Pa Dutch cookie recipes. These are my absolute favorite of all her cookie recipes. The egg washed tops make them awesome! Nana didn't use cutters for these; she simply ran a knife down columns, then across to make squares....no rerolling and no waste!!! Prep time includes chill time. The amount of pecan halves and cinnamon sugar is an approximation; you need just enough to sprinkle each and place a pecan half on each.
