This classic banana cake recipe from May 1938 reflects a timeless approach to using overripe bananas for something special. Enhanced with sour milk and a touch of citrus extract, it produces a moist, tender crumb and rich banana flavor. It’s a perfect example of resourceful home baking from the early 20th century, simple, frugal, and delicious. The use of both vanilla and citrus extract provides depth, while the sour milk and soda ensure a fluffy rise without needing modern leaveners. Great for brunches, potlucks, or any time you crave a nostalgic dessert.
