Mix crushed pineapple (20 oz) with juice and dry pudding mix together in a bowl. Add 1 cup Cool whip and stir gently until incorporated. Refrigerate.
Bake an angel food cake. Let cool completely.
You can cut the cake into 3 layers and place filling on top of each layer and top of cake. Decorate with fresh berries. Or you can scoop filling onto store-bought shortcakes and top with fresh berries. Or do what I opted and cut a piece of angel food cake in pieces and layer in a parfait glass with filling and fresh berries. Very light and refreshing and simple to throw together.
