Preheat the oven to 350 degrees. Grease a 9x13” dish; set aside.
Place the sliced apples in a large bowl.
In a medium bowl, combine the spices, cornstarch, and sugars. Add this mixture to the apples and toss. Combine the water and 1 teaspoon of vanilla in a small measuring cup; pour over the apples and toss again.
Evenly spread the apple mixture in the bottom of the grease dish.
Sprinkle ¾ of the cake mix evenly on the top of the apples.
Combine the melted butter and remaining teaspoon of vanilla; stir.
Pour the butter-vanilla mixture evenly over the cake mix.
Sprinkle the walnuts over the top.
Bake in the preheated oven for 1 hour or until browned on top and the edges are bubbling.
Remove the pan from the oven. The cake can be served very warm or slightly cool. (It’s better warm.) Vanilla ice cream is wonderful with this Apple Dump Cake (or any dump cake!)
Notes
My first attempt at this recipe used the whole (15.25-ounce) box of cake mix. Everyone agreed it was just too much. Half the package seemed too little, so ¾ of the box was definitely the “sweet spot.”Don’t throw away the remaining cake mix! Use it for individual Spice Mug Cakes.
