Description

This elegant Flag Cake elevates a holiday classic with a refined buttermilk yellow sponge and a silky cream cheese frosting. Decorated with precisely arranged fresh blueberries and raspberries, it serves as a stunning and delicious centerpiece for any summer celebration.


Ingredients

  • Unsalted butter, softened
  • Granulated sugar
  • Large eggs, room temperature
  • Vanilla extract
  • Buttermilk
  • All-purpose flour
  • Baking soda
  • Salt
  • Full-fat block cream cheese
  • Confectioners’ sugar
  • Fresh blueberries
  • Fresh raspberries


Instructions

  1. Preheat oven to 350°F (175°C) and thoroughly butter and flour a 9×13-inch metal pan.
  2. In a stand mixer, beat the softened butter and sugar on medium speed until the mixture is pale and fluffy, about 5 minutes.
  3. Add vanilla extract, then beat in eggs one at a time, allowing each to fully incorporate before adding the next.
  4. Reduce mixer speed to low and add one-third of the flour mixture (flour, salt, baking soda), followed by half of the buttermilk; repeat, finishing with the final portion of flour.
  5. Spread the batter evenly into the prepared pan and bake for 30 to 35 minutes until a toothpick comes out clean.
  6. Allow the cake to cool completely on a wire rack before frosting.
  7. Beat cream cheese, butter, vanilla, and salt until light, then gradually add confectioners’ sugar on low speed before whipping on medium-high until fluffy.
  8. Spread the frosting smoothly over the cooled cake, reserving one tablespoon of frosting for the star details.
  9. Outline a rectangle in the upper left with blueberries, then create stripes using rows of plain raspberries and sugar-rolled raspberries for the red and white pattern.

Notes

To achieve the most vibrant flag design, pat your berries completely dry with a paper towel after washing to prevent juice from bleeding into the white frosting. If you are serving this in a warm environment, chill the cake for 30 minutes after frosting but before decorating to provide a firmer base for the fruit.
