Pour the cherry pie filling into the casserole dish.
Sprinkle the cake mix evenly over the cherry pie filling.
Pour the melted butter over the cake mix, covering it as well as possible.
Cover the casserole dish with tinfoil and bake for 15 minutes, then remove the tinfoil and continue to bake until cake mix appears cooked and no pools of melted butter remain, about 15 additional minutes.
Scoop and serve with whipped cream or ice cream.
Notes
Don't overmix—just stir until combined to keep the cake tender.
Line your pan with parchment paper for easier removal.
A bundt pan adds elegance, but a 9x13-inch works perfectly too.
Add ½ cup mini chocolate chips to the batter for bonus richness.
Want to get fancy? Dust with powdered sugar or drizzle with chocolate ganache once cooled.
