Want a slice of moist, vanilla flag cake with blueberries and strawberries baked right in? I’ve been planning this American Flag Cake with fruit for weeks. I wanted something simple but special for the 4th of July, and this hit the mark. Fresh blueberries and thinly sliced strawberries bake into a tender white cake, adding bright flavor and festive color.
Special Holiday
This year is my first 4th of July as a Canadian permanent resident. I’ll always keep my American citizenship, but living in Canada has made me especially grateful to call two wonderful countries home. Baking a patriotic cake felt like a nice way to celebrate that feeling.
Strawberries and Blueberries
Patriotic desserts are everywhere around Independence Day—bright strawberries and blueberries look fresh, seasonal, and fun. Baking the fruit into the cake rather than just topping it gives the dessert a unique, homey touch and lets the berries’ juices perfume the cake as it bakes.
Cake Base
I used my great-grandmother’s reliable white layer cake recipe, but instead of two layers I baked one large 13 x 9-inch sheet cake and increased the bake time slightly. The result is moist, tender, and easy to prepare—perfect for entertaining.
Make One Large or Many Small Flags
You can bake this as one big flag or cut it into multiple individual flags. A single large cake is faster and simpler, while smaller individual flags are fun to serve. Both options look festive and taste great.
How to Make Individual Flags
After pouring the batter into the pan, divide the top surface visually into thirds horizontally and vertically to create nine flag-sized pieces. You can measure for uniformity or keep it rustic and freehand for a homemade look.
To decorate, arrange two rows of three blueberries in the top-left corner of each flag to form the blue field. Then lay thin strawberry slices across the rest of the flag area to create stripes. I used four horizontal strawberry rows, including the shorter rows beside the blueberries.
The aroma as the cake bakes—sweet strawberries and warm blueberries—is irresistible. The finished cake looked adorable and smelled even better coming out of the oven.
This cake is lovely on its own but even better with a dollop of whipped cream or a scoop of ice cream. The fruit and vanilla cake are balanced and not overly sweet, so it pairs well with cool, creamy accompaniments.
I hope you enjoy this festive American Flag Cake with fruit. It’s simple to assemble, bakes into a moist tender cake, and makes a cheerful centerpiece for holiday gatherings.

Pin Recipe
Ingredients
- ½ cup butter, room temperature
- 1 cup sugar
- 1 tsp vanilla
- 2 eggs, room temperature
- 2 cups flour
- 2 ½ tsp baking powder
- ½ tsp salt
- 1 cup milk
- 1 cup blueberries
- 4 cups whole strawberries, hulled and thinly sliced
Instructions
-
Preheat oven to 350°F. Butter a 13 x 9-inch cake pan and line it with parchment paper, leaving an overhang on the long sides to lift the cake out easily after baking.
-
Cream the butter, sugar, and vanilla until light. Add the eggs one at a time, beating well after each addition.
-
Sift the flour, baking powder, and salt together. Add the dry ingredients to the butter mixture alternately with the milk, beginning and ending with the dry ingredients. Beat until combined, then pour the batter into the prepared pan.
-
Arrange the fruit: in the top-left corner place two rows of three blueberries to form the blue field. Lightly press strawberry slices into the batter to form stripes across each flag section. Repeat for three flags in the first column and then for the remaining columns if making individual flags.
-
Bake for 30–35 minutes, until a toothpick inserted near the center comes out clean. Cool the cake in the pan, then lift it out using the parchment overhang. Slice into flag shapes and serve warm or at room temperature.
