Flag Cake for 4th of July

PREP. Preheat oven to 375°F. Grease an 11×15 baking pan and set aside.

BATTER. Bring 1 cup of butter and 1 cup of water to a boil in a saucepan.

Remove from heat and whisk in flour, baking soda, salt, sugar, eggs, sour cream, and almond extract until smooth.

BAKE. Pour into prepared baking pan. Bake for 20-22 minutes or until a toothpick inserted in the center comes out clean. Cool in the pan on a wire rack for 20 minutes.

FROSTING. While the cake is cooling, make the frosting. In a medium bowl, cream together cream cheese, softened butter, powdered sugar, and pineapple juice with the hand mixer. Spread frosting over the cooled cake.

BERRIES. Add blueberries and sliced strawberries to look like a flag. Chill for 1 hour before serving.

Decorating Tips

Different fruit designs. This idea can be adjusted to create different designs. Find different colored fruits and arrange them to resemble your country’s flag.  

  • Red: cherries, strawberries, and raspberries
  • Yellow/Orange: banana slices, peaches, apricots, pineapple, and oranges
  • Green: grapes and kiwi
  • Blue/Purple: blueberries, grapes, blackberries, and plums

Piping on frosting stripes. The layer of white frosting acts as the white stripes between the red strawberry stripes.

To enhance the white, use a piping bag and star tips. Use a small star tip to add dollops between the blueberry stars and a large star tip to dollop stripes between the red stripes. (You may need to make extra frosting).

Double-layer cake. Once the sheet cake cools, cut it in half widthwise. Add a layer of frosting on top of one side of the cake. Place the other half of the cake on the frosting. Frost the top of the cake and decorate it to look like a flag.

Recipe Tips

Here are some of our best tips and tricks for getting the best results, and getting them more easily!

  • Room temperature ingredients. Use room temperature ingredients so that the cake batter and frosting ingredients come together more easily. 
  • Easy clean up. Lining the baking pan with parchment paper can help keep the cake from sticking to the pan.
  • Colored cake. Make a red cake or blue cake by adding food coloring to the cake batter.
  • Fruit alternative. This recipe uses strawberry slices, but strawberry halves or even rows of raspberries will work.

Storing Info

Make ahead of time. Fully prepare and top the Flag Cake Recipe one day in advance. Keep it covered and put it in the fridge until ready to serve.

To prepare it sooner, leave the fruit topping off and keep it in the fridge for 2-3 days. 

Freeze ahead of time. Another way to prepare this cake in advance is to freeze the cake and the frosting separately. Allow the cake to cool completely, and wrap it with plastic wrap and again with foil. Freeze for 2-3 months.

Place the cream cheese frosting in an airtight container and freeze for up to 3 months. Thaw the frosting before spreading it on the cake. 

STORE. Cover and store American Flag Fruit Cake in the fridge for 2-3 days, or wrap tightly with plastic and foil and freeze for up to 2 months.

Since the berries will become mushy fairly quickly, be sure to remove the berries when storing for longer than a couple of days.

Recipe FAQ

Can I use a box cake mix?

For a shortcut, use a boxed cake mix and canned frosting. Decorate the top with fresh berries.

How can I make this cake more moist?

You can substitute part of the butter with vegetable oil, so ½ cup butter and ½ cup vegetable oil. Additionally, you could use brown sugar instead of granulated sugar, but keep in mind that it will darken the cake.

    Super fun cake! I did it in the sheet pan, but cheated a bit and used a box cake mix. I made the icing and used my cute piping decorators to add a bit more to the white sections and used raspberries instead of strawberries. Was super fun and yummy. Thank you Kristyn for the great ideas and recipes.

    This is a particularly attractive cake. I have seen the flag cake idea before, but this is the prettiest. The design is lined up beautifully. I never considered the importance of lining up the “core” stripe in the middle of the strawberry slice. You have those stripes in such a straight line. It makes all the difference. I will be sure to follow your example.

    1. Yes, but baking time might need to be adjusted slightly. You’ll know the cake is done when you insert a toothpick and it comes out clean. Also, make sure not to overfill the 9×13 pan, since the cake will rise when baking. So you may or may not use all the batter. I’d say fill the pan to 2/3 full, no more.
