A simple and festive American flag sheet cake made with white cake mix, cream cheese frosting, and fresh strawberries and blueberries, perfect for patriotic occasions.

Ingredients

Scale
  • 1 box white cake mix (about 15.25 oz / 432 g)
  • 1 cup whole milk (240 ml), room temperature
  • 1/3 cup vegetable oil (80 ml)
  • 3 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • Red and blue gel food coloring
  • 8 oz (227 g) cream cheese, softened
  • 1/2 cup unsalted butter, softened (113 g)
  • 3–4 cups powdered sugar (360–480 g), sifted
  • 1 teaspoon vanilla extract
  • Pinch of salt
  • 1 cup fresh strawberries, hulled and sliced (about 150 g)
  • 1 cup fresh blueberries (about 150 g)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease the 9×13 inch baking pan with butter or non-stick spray and line it with parchment paper.
  2. In a large bowl, combine the white cake mix, whole milk, vegetable oil, eggs, and vanilla extract. Beat on medium speed for 2 minutes until smooth.
  3. Divide the batter into three parts: about 1/3 each. Add red gel food coloring to one portion until bright red, blue gel food coloring to another until deep blue, and leave the last portion white.
  4. Layer the batter in the pan: spoon blue batter into the top left corner (about 1/3 width and half height), red batter into rows on the right side and bottom for stripes, and fill remaining spaces with white batter.
  5. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean. The cake should spring back lightly when pressed.
  6. Let the cake cool in the pan on a wire rack for 20 minutes. Then lift out using parchment paper and cool completely before frosting.
  7. Beat the softened cream cheese and butter together on medium speed until smooth (2-3 minutes). Gradually add powdered sugar, one cup at a time, beating well after each addition.
  8. Stir in vanilla extract and a pinch of salt. Adjust frosting thickness with a bit of milk if needed.
  9. Spread the cream cheese frosting evenly over the cooled cake.
  10. Arrange sliced strawberries in neat horizontal rows for the red stripes and place blueberries densely in the blue rectangle area to mimic the American flag.
  11. Refrigerate the cake for at least 30 minutes to let the frosting set. Bring to room temperature before slicing.

Notes

Use gel food coloring to keep batter thick and colors vibrant. Cool cake completely before frosting to prevent melting. Arrange berries just before serving to avoid sogginess. For gluten-free or dairy-free options, use appropriate substitutes.
