Spray 2 8" or 9" pans with non-stick cooking spray. Prepare cake mix with water, eggs and vegetable oil called for on cake mix directions. Split batter evenly between both pans and bake, following directions on back of cake mix box. Let cakes cool completely and remove from pans.
In a large bowl, mix together cream cheese, powdered sugar, and vanilla until smooth. Fold in Cool Whip. Divide evenly and spread half of whipped cream mixture over each cake.
Top each cake with cherry pie filling. Refrigerate cakes until ready to serve.
Notes
I buy the biggest can of cherry pie filling that I can find and it will usually cover both cakes. Any kind of fruit filling would be excellent on here. When we use strawberries, we usually just buy fresh strawberries at the store and then by a box of "Danish Dessert" glaze and mix the strawberries in that . . . it's delicious.
