Mix together cake, eggs, vanilla, and pie filling with a spoon and bake in 9x13 greased pan for 35-40 minutes at 350 degrees.
When cake is semi-cool poke holes across the top of the cake and make your box of banana pudding according to instructions.
Pour pudding evenly over cake, add sliced bananas, and refrigerate.
Make Homemade Whipped Cream recipe (link above--can also use Cool Whip if preferred) and smooth over top of the cake and pudding. Top with fresh cut strawberries, sprinkles, nuts and chocolate, as desired.
