A vibrant and easy 4th of July dessert featuring a moist vanilla sheet cake topped with tangy cream cheese frosting and fresh strawberries and blueberries arranged in a patriotic flag design.
Do not frost the cake while it is warm to prevent the frosting from melting and sliding off. Use room temperature ingredients for best results. Thinly slice strawberries to help them stay in place and prevent sogginess. Chill the frosted cake before serving to set the frosting and make slicing cleaner. Frozen berries can be used if thawed and drained well.
