   1. Preheat oven to 350'F. Position oven rack in bottom

   and salt onto clean sheet of waxed paper.

   cream of tartar, vanilla. Beat in remaining sugar, 1
   tablespoon at a time, until soft peaks form.

   rubber spatula just until incorporated. Repeat with
   remaining flour mixture.

   cake springs back when gently pressed with fingertip and
   sides of cake just begin to pull away from pan. Invert pans
   onto wire racks. Elevate cakes by placing corners of racks
   over filled 1 pound cans. Let cakes cool, upside down in
   pans, on elevated racks, for 1 hour. then run small metal
   spatula or knife between edge of cake and pan. Turn cake
   out onto rack to cool.

   filled cake, cut heart from center of one layer, leaving 1
   1/2" border all around. Spread other layer with some of
   Cherry-Yogurt Filling; top with cutout layer. Fill hollow
   with remaining cherries. Refrigerate.
