Pour the cherry pie filling into a 9 by 13 inch baking dish and spread evenly in the pan. Sprinkle the chocolate cake mix evenly over the top of the cherries. Cut the butter into slices and distribute evenly over the top of the cake mix. Sprinkle on the sliced almonds and bake for 1 hour or until the crust is set and the cherry mixture is hot and bubbly. Serve warm.
