For bars: Drain cherries well. Chop and set aside.
Cream butter and sugar in a mixing bowl. Beat in the eggs, vanilla, and almond extract. Add flour, salt, and baking powder. Stir till combined. Fold in the cherries.
Press dough into a well greased 9x13" pan. (I like to line mine with foil first.) Bake at 350° for about 20 minutes or till very lightly brown on the edges.
Cool bars completely, then frost with cream cheese frosting.
Frosting: Beat cream cheese and butter till smooth and creamy. Beat in vanilla, almond extract, salt, and enough powdered sugar to make a spreadable frosting. Spread on bars.
