Poppy-Seed Crunch

Recipe Instructions Cream the butter, gradually adding the sugar. Mix in the egg yolks and vanilla. Sift together the flour, salt and baking powder and add to the butter mixture. Pat into an 8-inch-square buttered pan. (The mixture won't hold together when you're handling it, but it will when baked.) Beat the egg whites until they begin to stiffen, then beat in the brown sugar. Fold in the poppy seeds. Spread over the dough. Bake in a 350 degree oven 25 minutes or until delicately browned and set. Cool and cut into squares.
