I love recipes that use cake mixs. We can often find these cake mixs at the grocery store for $1 or less.
1 box yellow cake mix
6 medium tart apples, peeled and sliced
2 tablespoons granulated sugar
1 teaspoon cinnamon
1/4 cup butter, melted
Preheat oven to 350 degrees. Combine the apple slices with the sugar and cinnamon in a large bowl. Sprinkle 1/4 of the cake mix over the top of the apples. Toss lightly until apples are completely coated. Pour into a greased 8-inch square baking dish. Bake for 30 minutes.
Place remaining cake mix in a medium bowl. Drizzle melted butter over the top. Toss until mixture forms large crumbs. Sprinkle over partially cooked apple mixture. Bake for 20 more minutes or until the top is puffed and yellow. Serve warm.
