Prepare the cake mix according to package instructions.
Pour half the cake batter into the prepared baking pan. Top with the cherry mixture. Pour the remaining cake batter over top and smooth lightly. Bake the cake according to package instructions, about 35 minutes, adding a few minutes. The cake is ready when a toothpick inserted in the center comes out clear of batter. Let the cake cool a few minutes before slicing.
For the garnish: In a small saucepan, heat the heavy cream and butter over medium-low heat. When the cream is just up to a simmer, remove from the heat and stir in the chocolate. Stir until the chocolate is melted and smooth.
Slice the cake and drizzle the melted chocolate over each slice. Garnish with a few whole cherries and some chopped chocolate.
