Ingredients

Scale
  • 2 ½ cups all-purpose flour (315g)
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup unsalted butter (2 sticks / 226g), softened
  • 1 ¾ cups granulated sugar (350g)
  • 4 large eggs, room temperature
  • 1 cup whole milk (240ml), room temperature
  • 2 teaspoons pure vanilla extract
  • 8 oz cream cheese (226g), softened
  • ½ cup unsalted butter (1 stick / 113g), softened
  • 4 cups powdered sugar (480g), sifted
  • 1 teaspoon pure vanilla extract
  • 2 tablespoons heavy cream (optional)
  • 1 ½ cups fresh strawberries, hulled and sliced
  • 1 ½ cups fresh blueberries
  • ½ cup fresh raspberries (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter or non-stick spray and lightly dust with flour.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Sift if possible.
  3. In a large bowl, beat softened butter and granulated sugar on medium speed until pale and fluffy, about 3-4 minutes.
  4. Add eggs one at a time, beating well after each addition.
  5. Mix in vanilla extract. Alternately add dry ingredients and milk to the butter mixture, starting and ending with dry ingredients. Mix on low speed until smooth.
  6. Pour batter into prepared pan and spread evenly. Tap pan gently to release air bubbles.
  7. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  8. Cool cake completely on a cooling rack before frosting.
  9. Beat cream cheese and softened butter together on medium speed until smooth, about 2-3 minutes.
  10. Gradually add sifted powdered sugar and vanilla extract, mixing well after each addition. Add heavy cream a teaspoon at a time if frosting is too thick.
  11. Spread an even layer of frosting over the cooled cake using an offset spatula.
  12. Arrange blueberries in the top left corner in a square shape. Alternate rows of sliced strawberries and raspberries to mimic flag stripes.
  13. Optional: Chill the cake for at least 30 minutes before serving for cleaner slices.

Notes

Use room temperature cream cheese and butter for smooth frosting. Avoid overmixing the batter to keep the cake tender. Chill the cake before slicing for cleaner cuts. Large strawberries should be sliced thinly for even stripes. For dairy-free frosting, use soaked cashews blended with coconut oil and maple syrup. Gluten-free flour blends can substitute all-purpose flour but may alter texture.
