Preheat oven to 350 and line a 15"x10"x1" baking sheet with parchment paper. Grease parchment paper with nonstick cooking spray.
Add eggs to a mixing bowl and beat for 5 minutes until light lemon in color and bubbly/frothy.
Add cake mix, water and vegetable oil and beat well.
Measure 3-1/2 cups of batter. Spread batter into prepared pan and bake 14-16 minutes or until edges begin to brown and center is set.
Dust a towel with powdered sugar and place the cake onto the towel, parchment paper facing up.
Peel away the parchment paper and discard. Starting on a short end, roll up the towel and cake to create a log. Let stand to cool completely.
Add heavy whipping cream and powdered sugar to a mixing bowl fitted with a wire whisk. Beat for 5-6 minutes or until stiff peaks form. Remove about 1/2 cup of whipped cream and place it into a piping bag fitted with a tip. Set aside.

Unroll cake and spread filling in the center.
Top with fresh cut strawberries.
Re-roll and place onto a serving platter. Add garnish of fresh whole strawberries and reserved whipped topping. Cover and refrigerate until ready to serve.
