Ingredients
Scale
- 1 box white cake mix (e.g., Betty Crocker)
- Ingredients called for on the cake box (usually eggs, oil, and water)
- 1 (8 oz / 227 g) tub of Cool Whip, thawed
- 1 cup fresh strawberries, sliced
- 1 cup fresh blueberries
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick spray.
- Prepare the cake batter by combining the white cake mix with eggs, oil, and water according to the package instructions. Beat with an electric mixer for 2 minutes on medium speed or stir vigorously by hand until smooth.
- Pour the batter into the prepared pan and spread evenly with a spatula.
- Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
- Let the cake cool completely in the pan, about 45-60 minutes.
- Spread the thawed Cool Whip evenly over the cooled cake using a spatula.
- Decorate the cake by arranging blueberries in the top left corner and sliced strawberries in stripes across the rest of the cake to create a flag pattern.
- Refrigerate the cake for at least 1 hour before serving to allow flavors to meld and the Cool Whip to set.
Notes
Do not spread Cool Whip on a warm cake to avoid melting. Use fresh, firm berries and pat dry to prevent sogginess. You can prepare the cake a day ahead but add Cool Whip and berries just before serving. For dairy-free, substitute Cool Whip with coconut-based whipped topping. For gluten-free, use gluten-free cake mix and Cool Whip labeled gluten-free.
