Beat 3 eggs well add 1 cup sugar, 1 tsp vanilla beat until light and fluffy. Combine & mix to top 3 (this has me confused and I am thinking she meant to combine with the next three ingredients with the egg and sugar mixture), 1 cup flour, 1 tsp baking powder, 1/2 tsp salt.
(Then I think we are to add these ingredients): 3/4 cup Marischino cherries (you can reserve the leftover juice for Kenny Lysdahl brandy Manhattans :-)), 1 1/2 cup chopped dates, 3/4 cup nuts. Bake 350/30 to 35 minutes. Sprinkle with powdered sugar cut into squares.
(She says nothing about letting the bars cool before sprinkling with powdered sugar and before cutting into squares...and I think that would be advisable).
