Cranberry Crumb Cake 2 Recipe

Mix flour, baking powder, salt, and sugar together. Cut margarine into this mixture. Add egg (beaten with a fork) and mix with the crumbs. Lightly press half of this mixture into the bottom of a greased 9 x 13 x 1" pan. Spoon on all of the filling. Sprinkle remaining crumbs on top. Bake at 350° for 30 minutes or until lightly browned. Serve with Cool Whip or Ice Cream.
