Put half of the angel food cake mix in a bowl with the vanilla, water and shortening. Mix with a pastry blender until it becomes like pie crust. If it gets too moist, add some powdered sugar, a small amount at a time. Sprinkle the counter with powdered sugar and roll out the dough. Use a cookie cutter to cut the dough into shapes. Place dough shapes on a cookie sheet. Bake at 350 degrees F for 12 minutes or until lightly browned.
While the shapes are cooking, take the other half of the angel food mix and follow the directions on the box dividing the ingredients by half. Either cook this mix in small angel food pans or in a larger cake pan, filling the pans 3/4 of the way to the top. Bake at 350 degrees F for 10 minutes. Cut into shapes that match the dough shapes above.
Cut up strawberries and mix with whipped topping.
To assemble, place a dough shape on the bottom, stack cake, whipped topping mix, then another dough shape on top. Put a small dollop of marshmallow fluff and then a strawberry to finish.
