Preheat oven to 350°F (175°C). Lightly grease a 9x13-inch (23x33 cm) baking dish with butter or nonstick spray.
02 -
In a large bowl, mix cherries, sugar, cornstarch, lemon juice, vanilla, and almond extract (if using) until cherries are evenly coated with no dry starch visible.
03 -
Pour the cherry mixture into the prepared baking dish, spreading evenly to cover all corners.
04 -
Evenly sprinkle the dry vanilla cake mix over the cherries, breaking up large clumps without pressing down.
05 -
Slowly drizzle the melted butter evenly over the cake mix to moisten as much surface area as possible; optionally, mist any dry patches with cooking spray.

Bake for 35 to 45 minutes until the topping is golden brown and cherry juices bubble at the edges. Let rest for at least 15 minutes to allow juices to thicken before serving.
