Mix favorite chocolate cake according to package directions, except subsitute cola for water. Bake as usual. I did a 9 9 x 13 pan. Cool completely.

Mix remaining cola with 1 can cherry pie filling , cook in saucepan till it thickens, stirring now and then. Cool and spread on cake.

I made a cooked frosting to pipe around my edges but this is not necessary, you can serve this cake with cool whip if you like.
