Preparation
Preheat oven to 350°. In a large bowl, combine the cake mix, water, eggs and oil; beat on low speed for 30 seconds. Beat on medium speed for 2 minutes.
Pour into 2 greased and floured 9-in. round baking pans. Bake until a toothpick inserted in the center comes out clean, 25-35 minutes. Cool for 10 minutes; remove from pans to wire racks to cool completely.
Using a serrated knife, level tops of cakes if necessary. Return layers, top side up, to 2 clean 9-in. round baking pans. Pierce cakes with a meat fork or wooden skewer at 1/2-in. intervals.
Drain juice from strawberries into a 2-cup measuring cup; refrigerate berries. Add water to juice to measure 2 cups; pour into a small saucepan. Bring to a boil; stir in gelatin until dissolved. Chill for 30 minutes. Gently spoon over each cake layer. Chill for 2-3 hours.
Dip bottom of 1 pan into warm water for 10 seconds. Invert cake onto a serving platter. Top with chilled strawberries and 1 cup whipped topping. Place second cake layer over topping.
Frost cake with remaining whipped topping. Chill for at least 1 hour. Serve with fresh berries if desired. Refrigerate leftovers.
