Light Molasses (Best Option)
1/2 teaspoon per 1 tablespoon soy sauceLight molasses contains natural sugars and trace minerals that provide a mild umami flavor similar to soy sauce but with a sweeter profile, making it suitable for sweet baked goods like pound cake.
Use sparingly to avoid adding too much sweetness or moisture; incorporate it well with the wet ingredients to ensure even distribution.
The final cake will have a slightly richer flavor with a hint of caramel undertones, maintaining the traditional pound cake sweetness while adding subtle depth.
