A festive and easy-to-make layered berry sheet cake featuring red strawberries, white cream cheese frosting, and blue blueberries arranged like the American flag. Perfect for summer celebrations and patriotic occasions.
Use room temperature eggs, butter, and cream cheese for best results. Thaw and drain frozen berries fully to prevent soggy frosting. Chill cake before frosting to avoid melting. If frosting is too soft, add more powdered sugar; if too stiff, add a splash of milk. For gluten-free, substitute flour with gluten-free blend and add xanthan gum. For dairy-free, use vegan butter, dairy-free cream cheese, and plant-based milk.
