- 1 (15.25-ounce) box white cake mix
- 1 cup water (or as listed on cake mix box)
- 1/2 cup vegetable oil (or as listed on cake mix box)
- 3 large egg whites (or as listed on cake mix box)
- 1 cup boiling water
- 1 (3.3-ounce) box strawberry gelatin
- 1 (8-ounce) container whipped topping
- 1 cup fresh blueberries
- 1 pound fresh strawberries, sliced or halved
Preheat oven to 350°F. Spray 13×9 cake pan with nonstick cooking spray.
In a large bowl, beat cake mix, water, oil and egg whites with an electric mixer on low speed for 30 seconds. Scrape the sides of the bowl. Then beat on medium speed for 2 minutes. Pour into prepared pan. (Note: Do not eat raw cake batter.)
Bake 23-28 minutes or until toothpick inserted in the center comes out clean. Cool on rack 20 minutes.
In a medium bowl, pour boiling water on gelatin; whisk briskly until dissolved.
Poke cake at 1-inch intervals with the handle of a wooden spoon or the tines of a fork halfway into the cake. Carefully and slowly pour the strawberry gelatin over the cake. Chill completely in the refrigerator, about 1 hour.
Spread the whipped topping evenly over the cake. Arrange the blueberries and strawberries to resemble the stars and stripes of the American Flag.
Cut the cake into 12 generous pieces. Note: For a clean slice, wipe the knife after each cut.
Keep the cake chilled. Tightly cover cake and keep in the refrigerator 2-3 days.

Cake flour is a very finely milled white flour made from a soft winter wheat. Cake flour is also traditionally very heavily bleached. The bleaching process and the variety of wheat it is made from produces a flour that has a very low protein content. The flour is velvety in texture and produces beautifully delicate pastries. While unbleached cake flours do exist, they are reported to preform poorly compared to traditional bleached cake flour. Learn more about The Function of Flour in Baking.
