Substitute
Substitute 2 pkg. (600 g each) frozen sliced strawberries, thawed, for the fresh strawberries.
Make Ahead
This dessert is best when assembled just before serving. But if you prep all the ingredients ahead of time, you can assemble it in just minutes! Bake the cake up to 24 hours ahead of time, then split the cake into layers after it is cooled and store in airtight container at room temperature. Toss the sliced berries with the sugar and refrigerate until ready to use. And refrigerate the Cool Whip overnight to thaw.
