How to Make Flag Cake

Prep the Oven & Mixing Bowl: Preheat your oven to 350°F (175°C). In a large mixing bowl or a stand mixer, combine 2 1/4 cups all-purpose flour, 1 1/2 cups sugar, 2 teaspoons baking powder, and 3/4 teaspoon salt. Mix well!
Incorporate Butter: Gradually add 1 cup of cubed butter to the flour mixture. Mix on low speed until the mixture resembles coarse crumbs, about 2–3 minutes.
Whisk Wet Ingredients: In a separate bowl, whisk together 2 large eggs, 1 cup buttermilk, 3 tablespoons oil, and 2 teaspoons vanilla extract until well combined.
Beat Egg Whites: In another bowl, beat 3 large egg whites until soft peaks form. This step is key for a fluffy cake.
Combine Mixtures: Slowly add half of the egg-milk mixture into the dry ingredients, mixing until well combined. Carefully fold in the beaten egg whites until the batter is light and fluffy, then gently mix in the remaining egg-milk mixture.
Bake the Cake: Lightly spray a 9 x 13-inch cake pan with non-stick cooking spray. Pour the batter into the pan and bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan.
Prepare Frosting: While the cake cools, whip 2 cups of heavy cream in a bowl until stiff peaks form. In another bowl, beat 16 ounces of softened cream cheese for about 2 minutes until smooth, then gradually add 2 1/2 cups of powdered sugar and 1 teaspoon of vanilla bean paste, mixing until fluffy and smooth.
Combine Frostings: Gently fold the whipped cream into the cream cheese frosting until well incorporated. Chill until you’re ready to frost your cake.
Frost the Cake: Once the cake is completely cooled, spread a generous layer of frosting over the cake’s surface and sides if visible.
Decorate with Berries: Fill the top left section with blueberries or blackberries for the stars. Use raspberries and sliced strawberries to create alternating red stripes, adding white frosting swirls with a star-tip to accentuate the stripes beautifully.
Final Touch: Use a large star tip to pipe white frosting in zigzag motions across the stripes for fun texture. Keep the cake covered in the refrigerator until you’re ready to serve.

Storing & Reheating

To enjoy your Flag Cake days later, store it covered in the refrigerator for up to 5 days. If you need to keep it longer, it can be frozen for up to 3 months—just remember to use an airtight container or wrap it well in plastic wrap. To refresh, let it thaw in the refrigerator overnight. Note that freezing may alter the texture slightly, but the flavors will still be excellent!

Chef’s Helpful Tips

Beat Egg Whites Properly: Ensure your mixing bowl is clean and free of grease when whipping egg whites; any fat can prevent them from reaching their full volume.
Room Temperature Ingredients: Using room temperature eggs and cream cheese helps create a smooth batter and frosting.
Don’t Overmix: Once you add the flour mixture to the wet ingredients, mix just until combined; overmixing can result in a dense cake.
Chill Your Cake Before Frosting: Allow the cake to cool completely before frosting to prevent melting and sliding.
Make It Ahead: Bake the cake a day in advance and frost it on the day you’ll serve, ensuring the freshest flavors.

When it comes to a show-stopping dessert, Flag Cake truly shines. It’s a simple yet impressive way to celebrate America’s red, white, and blue while unleashing a wave of flavor that everyone loves. Don’t hesitate to experiment—feel free to swap fruits according to your preference or seasonal availability. Each bite is a burst of cake, cream, and fresh fruit, and it’s just waiting to be enjoyed. Happy baking!
