Preheat oven to 350 degrees.
2 cans (21-oz each)
1 box (2-layer size) devil's food cake mix
Whipped cream for garnish, if desired
Pour the pie filling and spread evenly in an ungreased 9 x 13-inch baking pan. Place in the oven and bake at 350 degrees for 5 minutes.
Make the cake mix according to the package directions. Remove the cherry pie filling from the oven and pour the cake mix batter evenly over the cherries.
Bake at 350 degrees for 40 to 45 minutes or until a wooden toothpick inserted near the center comes out clean. While still warm, cut into squares and turn upside down to serve. Garnish with a dollop of whipped cream, if desired.
NOTE: You can easily make this a diabetic dessert by using a sugar-free cake mix, pie filling with Splenda, and sugar-free whipped cream.
