July 4 Flag Cake

July 4 recipe for American flag cakeWe have a traditional 4th of July gathering every year at my house and, ever since I was young, my aunt used to make a flag cake. Now, I’m the one making it because some traditions are too tasty to forget!

Since it’s a double layer rectangular cake, I like to make a jelly roll thin-style cake and a simple whip cream filling and icing. Feeling ambitious? Follow the jelly roll recipe two times to make a double layer. You will also need a 15.5 x .5 x 10.5” jelly roll pan (a baking sheet with rims.)

Jelly Roll


  • 3 large eggs
  • 1 c sugar
  • 5T water
  • 1t vanilla
  • 1c flour
  • 1t baking powder
  • ¼ t salt


  • Preheat oven to 375 °F.
  • Beat eggs until thick.
  • Gradually beat in sugar.
  • Beat in water and vanilla.
  • Sift together flour/baking powder/salt and beat into bowl.
  • Mix until just smooth and pour into lined jelly roll pan.
  • Bake for 12-15 minutes.
  • Once done, loosen edges and immediately turn upside down onto cutting board (or your actual serving dish or a towel sprinkled with confectioners’ sugar.)
  • Repeat to make a double layer cake or cut down the middle to make a smaller version double layer.

Whipped Cream (or check out alternative fillings — chocolate, coffee and custard — here)


  • 1 pint heavy cream
  • 1.5 t vanilla
  • 1T confectioners’ sugar (add more sugar if you prefer a sweeter whip cream or omit sugar altogether for healthier version)


  • To speed up the process, I strongly recommend the use of a standing mixer or electric hand held mixer.
  • Whip the cream until it starts to thicken.
  • Add vanilla and gradually add sugar.
  • Beat until cream starts to form little peaks.

Cake Assembly

To assemble cake, you will need the 2 jelly roll cake layers (any thinned edges trimmed off), whipped cream, strawberries and blue berries.

  • Spread 1/3 of your whip cream on the first sheet of cake.
  • Carefully place the 2nd layer on top of the whipped cream.
  • Spread remaining whip cream onto cake, including all the sides.
  • Top with whole blueberries and ½ or ¼ cut strawberries (the thinner the strawberries the more rows you can get…the more technically correct your flag cake will be.)

Happy Independence Day!
