Recipe FAQ
How to make a colorful cake layer?
- Make a red cake or blue cake by adding food coloring to the cake batter.
Want a shortcut?
- Instead of making the cake from scratch, use a box of white cake mix. Replace the buttercream frosting with canned frosting, Whipped Cream, or Cool Whip. Decorate the top with fresh berries as instructed.
Do I need to use fruit to decorate the top?
- Make a double batch of frosting. Make ยผ of it blue and ยผ of it red. Use a small star tip to add dollops of blue stars in the corner. Use a large round tip to pipe the red stripes. If you don’t have a pastry bag or piping tips, you can use a gallon Ziploc and snip off one of the corners.
Want to make a 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.
Can I make the cake ahead of time?
- Fully prepare and frost the top of the flag cake recipe one day in advance. Keep it covered and add the fresh fruit up to 3 hours before serving.
How do I freeze the cake ahead of time?
- 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 and adding fresh fruit.
How to store American Flag cake?
- 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. Remove the berries when storing for longer than a couple of days.
Do i need to cook down the butter and water before adding the eggs? Thank you!
Yes!
I love this recipe. It is the perfect summertime festive treat. My kids love helping with the berries.
So easy, light and festive cake. I’ve made this cake before and received rave reviews.
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.
My grandkids loved helping me make the flag cake! It is so festive and tastes delicious!
Love this patriotic cake! It is so festive and tastes great! My grandson and granddaughter had fun helping to make it!
Oh I’m so happy to hear that! Thanks for giving the recipe a try!
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.
The cake didnโt rise up like a usual cake.
Can this be made in a 9×13 pan? (Single layer?)
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.
