Ingredient Notes

Ingredients needed to make a flag cake with fresh berries and a white cake.

Cake flour. Processed more finely than all purpose flour, Cake Flour makes the cake extra light and fluffy. Learn how to measure flour properly, as well as how to make cake flour substitute!

Buttermilk. You can use store bought or my homemade buttermilk substitute.

Blueberries and strawberries. Prep the fresh fruit by washing and patting dry with a paper towel. Don’t forget to remove the stems of the strawberries.

Easy Assembly

Step by step photos showing how to assemble a flag cake.

First, bake and cool the white cake in 9 x 13 pan. I use my homemade white cake recipe, but even a box mix would work in a pinch (although my homemade recipe is pretty incredible. You could even use my vanilla sheet cake recipe for a buttery, vanilla flavor!

Now, spread cool whip over the whole top of the cake. You could also use homemade whipped cream if you prefer. Want something richer? Add vanilla buttercream frosting to the top instead!

Arrange the blueberries in the top left quadrant.

Line up the strawberry halves or slices on the top right quadrant and the entire bottom half of the cake. Leave a little space of white between the rows.

Tips and Tricks

  • Cut strawberries in half or slices. Halving the berries instead of slicing them thin, releases less water. As a result, the strawberries will release less color into the cool whip and keeps the flag cake from getting soggy. However, cutting them into slices results in a prettier presentation with more berry per bite. You decide which way to go on this one!
  • Boxed mix substitute. This recipe includes instructions for making a delicious white cake from scratch. If you prefer, you can totally substitute your favorite boxed white cake mix instead! Follow instructions on the box for baking the cake in a 9 x 13 pan.
  • Don’t waste the yolks from your eggs! After separating out the egg whites, reserve the extra yolks to make some Easy Homemade Lemon Curd later.
  • More Treats. Whip up a batch of these easy Red white and blue rice krispie treats for an on-the-go dessert this holiday!

Recipe FAQs

Can I use frozen strawberries and blueberries for Flag Cake?

I don’t recommend using frozen berries here. They tend to release more moisture, making the cake soggy.

Will homemade whipped cream work instead of cool whip?

Yes, homemade whipped cream makes a delicious topping too. Keep in mind that it is not stabilized like cool whip so it will be more likely to melt or slide off the cake in warm temperatures.

Does Flag Cake need to be refrigerated?

If you’re not serving the flag cake right away, keep it covered in the fridge to preserve the freshness. It’s best enjoyed within 1 -2 days of assembly.

Do you serve this cake from the pan? Or should I turn it out onto a serving platter?

I serve American Flag Cake right out of the pan. If you want to serve it another way, make sure to turn it out of the pan before frosting and topping.

Ingredients

For the Cake

  • 2 ½ cups cake flour
  • ½ teaspoon kosher salt
  • 1 Tablespoon baking powder
  • ¾ cup unsalted butter, softened
  • 1 ¾ cup granulated sugar
  • 5 large egg whites
  • 2 teaspoon vanilla extract
  • ¾ cup buttermilk

For the Topping

  • 16 oz Cool Whip, thawed
  • 1 pint fresh blueberries
  • 2 pounds fresh strawberries, halved or sliced (stems removed)

Instructions

    1. Preheat oven to 350 degres F. Grease and flour a 13x9 baking dish, or use baking spray (or use my homemade cake release). Set pan aside.
    2. In a bowl, combine cake flour, salt, and baking powder with a whisk. Set aside.
    3. In a large mixing bowl, beat room temperature butter with granulated sugar for about two minutes. Scrape down the sides of the bowl to make sure all the butter and sugar are combined. Add in egg whites and vanilla extract. Beat for 2 more minutes.
    4. Add in the dry ingredients and the buttermilk. Beat just until blended.
    5. Pour batter into prepared baking dish. Place on middle rack of the oven and bake for 35-40 minutes, until a toothpick inserted into the center comes out with just crumbs.
    6. Remove from oven and cool completely.
    7. When cooled, top with Cool Whip. Add blueberries in one corner for the stars, and make stripes with the strawberry halves.
