Key Ingredients for Your Festive Flag Cake
To make your easy flag cake, you’ll need:
- 16 ounces frozen sweetened strawberries, thawed
- 2 tablespoons cornstarch
- 1/3 cup cream sherry plus 1 tablespoon, divided (or orange juice)
- 3/4 cup sugar, divided
- 1/3 cup all-purpose flour
- Dash salt

Crafting Your Easy Flag Cake: Step-by-Step
Preparing the Sweet Strawberry Glaze
Start by preparing the sweet strawberry glaze. Scoop 1/2 cup juice from the thawed strawberries and mix it with cornstarch. In a heavy saucepan, combine the remaining strawberries and heat over medium-high until thickened, stirring constantly. Stir in 1 tablespoon of cream sherry and set aside to cool.
Making the Creamy Vanilla Custard
Next, let’s make the creamy vanilla custard. In the top of a double boiler, combine 1/2 cup sugar, flour, and a dash of salt. Blend in the 3 egg yolks and 2 cups milk. Cook over boiling water, stirring constantly for 10 to 12 minutes until thickened. Once done, remove from heat and cover the surface with plastic wrap. Refrigerate for 30 minutes.
Assembling the Cake Base Layers
Now it’s time to assemble your easy flag cake. Pour the cooled custard into the bottom of a 13×9-inch glass dish. Layer the thawed pound cake slices on top and brush the remaining 1/3 cup cream sherry over the cake slices. The sherry adds a lovely flavor that enhances the dessert!
Adding the Fruit and Topping
After the base is ready, spoon the cooled strawberry mixture over the cake. Sprinkle 1 cup of blueberries and 1 cup of raspberries over the top. Finish by spreading the thawed whipped topping evenly over the berries. For a festive touch, arrange the remaining berries to create a flag design.
Chilling and Decorating Your Flag Cake
Now, refrigerate your masterpiece for at least 1 hour before serving. This chilling time allows the flavors to meld beautifully, creating a delightful experience with every bite. Just before serving, make sure the design is intact, as it looks stunning on any table!
Tips for the Perfect Easy Flag Cake
Choosing the Right Dish for Your Flag Cake
For the ultimate flag shape, use a 3-quart glass 13×9 casserole dish or a 13×9 baking pan. This size ensures the layers are perfectly visible and easy to serve.
Best Practices for Berry Preparation
To prevent sogginess, dry your berries before adding them to the cake. Fresh berries not only taste better, but they also keep the flag design fresh and appealing.
Substitutions for a Custom Flag Cake
Want to switch things up? You can easily substitute angel food cake for the pound cake or use fresh strawberries instead of frozen ones. For a non-alcoholic option, replace cream sherry with orange juice or water. If you prefer a lighter topping, whip up fresh cream instead of using whipped topping!
Storing Your Easy Flag Cake
If you have leftovers (though they’ll be hard to come by!), cover the cake with plastic wrap and store it in the refrigerator. It’s best enjoyed on the first day to keep the fruit fresh and prevent any sweating that could ruin the design.
