We 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.)
- 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.
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!
