Variations and Substitutions

  • Use different Fruits – You can change the fruit to blackberries or rows of raspberries to makes this cake just as festive.
  • Use CandyIf you don’t have fruit on hand, and need a last-minute dessert, use M&M’s. We always seem to have M&M’s and it was a great to use this on this cake.
  • Sprinkles Work Great – You can even use patriotic sprinkles to make a flag cake.
  • Frosting. Homemade Cream Cheese Frosting Recipe is another great option that can easily be made with a paddle attachment and your stand mixer. You can also use a pastry bag and star tip to decorate with icing.

How do you decorate a cake like an American Flag?

  • Place the blueberries in a rectangle on the cake in the upper left corner. 
  • Then lay the strawberries slightly overlapping them to make the red stripes. Leave enough space so you still have white stripes in between.

Frosting Options

You can even change the frosting. Here are some of our favorites:

  • Cool Whip – Cool whip is easy frosting switch. We like that it is light and the fruit really holds up on the frosting.
  • Change the coloring – You can easily change the coloring of the frosting by adding food coloring.
Slice of cake on a plate.

Pro Tips

  • Preparing Berries – Slice the berries very thin so that they will lay flat to make the red stripes.
  • Use different flavors of cake – We used a white cake mix but angel food cake or yellow cake would work as well. You could even use those patriotic funfetti cake mixes. 
  • Change the Color of the Cake – Try using food coloring to make the cake different colors. You can do a row of red layers and a row of blue layers. My always love when I do a red cake and a blue cake.
  • Change the Frosting – Substitute whipped cream for the icing for a change. This is also really good!
  • Refrigerator Cake – Make sure to keep this cake in the fridge or serve immediately.
  • Make sure to use the right size of pan – Use a 9×13 pan to have plenty of room to make the flag design out of the fruit. Smaller size pans will not produce the desired outcome of a flag shape.

Can you make a Flag Cake ahead of time?

Yes, you can. You can prepare the cake and frost it and place in the refrigerator. When you are ready to serve the cake, decorate it with your fruit topping to make a flag.

You can place the fruit on up to a day before serving. I don’t recommend doing it any earlier than that as your fruit might get mushy.


To store leftovers, cover the Fourth of July cake with plastic wrap or with the baking pan lid and place in the refrigerator. It will stay good for up to 3 days.
