Coconut Aminos (Best Option)
1:1 (1 teaspoon coconut aminos per 1 teaspoon soy sauce)Coconut aminos are derived from fermented coconut sap and have a naturally sweet and savory profile similar to soy sauce but with less sodium. This makes it ideal for cupcakes where a subtle umami note is desired without overwhelming sweetness or saltiness.
When using coconut aminos, monitor the salt content of your batter since it is less salty than soy sauce; you may need to slightly adjust added salt. It blends well with sweet ingredients and does not affect batter texture.
Compared to soy sauce, coconut aminos maintain the umami complexity but with a gentler flavor, resulting in cupcakes that have a nuanced depth without any bitterness or harshness.
