This classic caramel icing recipe hails from a 1925 household account book, often used as both a ledger and recipe journal. Caramel icing was a staple in early 20th-century American kitchens, celebrated for its rich, buttery flavor and nostalgic appeal. It’s made by cooking sugar until caramelized and combining it with milk and butter to create a smooth, creamy topping that pairs perfectly with vanilla or spice cakes. The handwritten note suggests it was cherished for its simplicity and flavor, making it a timeless favorite for birthdays and family gatherings.
