Cut the angel food cake into bite-sized cubes and slice the fresh strawberries into thin pieces.
Whisk the softened cream cheese with marshmallow fluff, sugar, and vanilla until the mixture is smooth.
Fold in the thawed whipped topping gently with a spatula to maintain the airy texture.
Stir in the cake cubes and strawberries very lightly to avoid breaking the cake pieces.
Refrigerate the salad for thirty minutes so the cake can absorb the sweet strawberry cream.
Notes
Use a serrated knife to cut the cake into cubes to avoid crushing the air out of it. Wait to combine cake and berries until serving for the best texture.
