The History of 7UP Pound Cake 📜

The 7UP Pound Cake became popular in the Southern United States during the 1950s and 1960s when home bakers began using soda in baking for moisture and lift. Traditionally, pound cakes used one pound each of butter, sugar, eggs, and flour. Over time, creative bakers added ingredients like soft drinks for flavor and texture.

7UP became a favorite because of its lemon-lime profile, which pairs beautifully with buttery cakes.
