Carefully pour the melted butter and milk over the cake mix and pudding.
Use a whisk or spoon to mix until well combined.

Bake uncovered in the preheated oven for 35 minutes or until cooked through.
Remove from the oven and serve warm or room temperature.
Spray the 9x13-inch dish before baking and don't forget the corners!
