How to Make It
Preheat oven to 375°F. Coat a 13- x 9-inch baking dish with cooking spray.
Toss together peaches, salt, and 1/8 teaspoon of the cinnamon in a bowl. Transfer mixture to prepared baking dish. Spread cake mix evenly over peaches; sprinkle with remaining 1/8 teaspoon cinnamon. Arrange butter evenly over cake mix; sprinkle with almonds.
Bake in preheated oven until golden brown and set, 35 to 40 minutes. Serve warm or at room temperature.
