Preheat the oven to 350°F and grease a 9x13-inch baking dish.
Beat the softened cream cheese with granulated sugar and vanilla extract until smooth.
Spread the cherry pie filling evenly across the bottom of the baking dish.
Dollop the cream cheese mixture over the cherry filling and spread gently.
Sprinkle the dry yellow cake mix evenly over the top without pressing it down.
Drizzle the melted butter evenly over the cake mix, covering as much surface area as possible.
Top with chopped pecans and cinnamon if using.
Bake for 40 to 45 minutes until the top is golden brown and the edges are bubbling.
Allow the cake to cool for at least 15 minutes before serving.
