Ingredients

Scale
  • 2 ½ cups all-purpose flour (300g), sifted
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 ¾ cups granulated sugar (350g)
  • 4 large eggs, room temperature
  • 1 cup whole milk (240ml)
  • Zest and juice of 2 medium fresh lemons
  • 1 ½ cups fresh blueberries (225g), rinsed and patted dry
  • 8 oz (225g) cream cheese, softened
  • ½ cup (1 stick) unsalted butter, softened
  • 3 cups powdered sugar (360g), sifted
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon fresh lemon juice

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, and salt. Set aside.
  3. Using an electric mixer, beat softened butter and granulated sugar on medium speed until light and fluffy, about 3-4 minutes.
  4. Add eggs one at a time, beating well after each addition and scraping down the sides.
  5. Mix in lemon zest and lemon juice until just combined.
  6. With mixer on low, alternately add flour mixture in three parts and milk in two parts, beginning and ending with flour. Mix until just combined.
  7. Toss blueberries with 1 tablespoon flour to prevent sinking, then gently fold into batter with a spatula.
  8. Divide batter evenly between prepared pans and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then turn out onto cooling racks to cool completely.
  10. For frosting, beat cream cheese and softened butter until smooth and creamy.
  11. Gradually add powdered sugar, beating on low speed to avoid sugar clouds.
  12. Stir in vanilla extract and lemon juice until well combined.
  13. Place one cake layer on serving plate and spread a generous layer of frosting on top.
  14. Add second cake layer and frost top and sides evenly.
  15. Decorate the top with fresh blueberries in the top left corner to form the blue canton, and use sliced strawberries or lemon zest ribbons to create red and white stripes.

Notes

Avoid zesting the white pith of lemons to prevent bitterness. Toss blueberries in flour before folding to prevent sinking. Bake layers one at a time if oven space is limited. Chill cake briefly after crumb-coating for a clean frosting finish. Dip spatula in warm water before smoothing frosting for a professional look.
