A quick and festive flag cake made with store-bought vanilla cake mix, frosting, and fresh berries, perfect for patriotic celebrations and ready in just 30 minutes.
Ensure the cake is completely cool before frosting to prevent melting. Slice strawberries thinly for neat stripes. Dry berries well before placing on frosting to avoid sogginess. Store leftovers covered in the fridge for up to 3 days. Thaw and dry frozen berries if used.
