Preheat the oven – Set your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

Add the cherry filling – Spread the cherry pie filling evenly across the bottom of the baking dish.

Sprinkle the cake mix – Evenly sprinkle the dry chocolate cake mix over the cherries—don’t stir.

Drizzle the butter – Pour the melted butter evenly over the cake mix, covering as much of the surface as possible.

Bake – Bake for 35–40 minutes, or until the top looks set and slightly crispy, and the cherry filling is bubbling at the edges.

Cool and serve – Let the cake rest for 10 minutes before serving warm. Top with whipped cream, ice cream, or extra cherries if you like.
