Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 2 ½ teaspoons (10g) baking powder
  • ½ teaspoon (3g) salt
  • ½ cup (113g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 3 large eggs, room temperature
  • 1 ½ teaspoons (8ml) vanilla extract
  • 1 cup (240ml) whole milk, room temperature
  • 1 cup (150g) fresh strawberries, pureed
  • 8 oz (225g) cream cheese, softened
  • ½ cup (113g) unsalted butter, softened
  • 3 cups (360g) powdered sugar, sifted
  • 1 teaspoon (5ml) vanilla extract
  • Pinch of salt
  • 1 ½ cups (225g) fresh strawberries, sliced (for decoration)
  • 1 cup (150g) fresh blueberries (for decoration)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch pan with butter or non-stick spray and lightly flour it.
  2. In a medium bowl, whisk together sifted all-purpose flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar with an electric mixer on medium speed until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each addition. Stir in vanilla extract.
  5. Alternately add the dry flour mixture and milk to the butter mixture, starting and ending with the flour. Mix just until combined.
  6. Fold in the pureed strawberries gently to keep the batter airy.
  7. Pour batter into prepared pan and smooth the top with a spatula.
  8. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Let cake cool in the pan on a wire rack for 20 minutes, then remove from pan to cool completely before frosting.
  10. Beat softened cream cheese and butter together until smooth and creamy, about 2-3 minutes.
  11. Gradually add powdered sugar and beat until fluffy. Mix in vanilla extract and a pinch of salt.
  12. Spread an even layer of cream cheese frosting over the cooled cake using a spatula.
  13. Arrange sliced strawberries in horizontal rows on one side of the cake for the red stripes.
  14. Place blueberries in the top left corner in a rectangular cluster to represent the stars.

Notes

Use room temperature ingredients for better blending and smoother batter. Do not overmix batter to avoid a tough cake. Puree fresh strawberries for even flavor and color. Chill frosting if too soft before spreading. Arrange berries carefully to mimic the flag for best visual impact. For gluten-free, substitute flour with gluten-free blend; for vegan, use vegan margarine, flax eggs, dairy-free milk and cream cheese.
