This 7-Up Pound Cake is a nostalgic twist on the traditional pound cake, known for its unique use of lemon-lime soda, which gives the cake a moist texture and subtle citrus flavor. A popular dessert in Southern kitchens, it became a favorite during the mid-20th century thanks to its simplicity and memorable name. Loved for its dense, buttery crumb and a hint of lemony zing, it’s ideal for potlucks, holidays, or afternoon coffee.
