Waffle Cookies

A friend of mine made these before we moved and OH MY GOODNESS are they the best! She made them with a belgian waffle iron, but I guess you can make them with a regular waffle iron.
She says there is some improvising required (see where you add the flour in the directions).

Waffle Cookies

½ lb. butter
1 c. sugar
1 c. brown sugar
1 ½ tsp vanilla
3 eggs
5-ish c. flour

Cream butter and sugars. Add vanilla and eggs. Mix. Add enough flour to roll into balls. Use only enough that they won’t stick to waffle iron. Mix together powdered sugar, water and flavored extract to form thin glaze. Cook a couple at a time on hot waffle iron until very light brown, but cooked through (maybe 60 seconds). Dip in glaze while still hot (important). Drain on racks to cool
