⭐ Club Soda (Best Vegan Option)
Replace 1/4 cup liquid with 1/4 cup club soda per 3/4 teaspoon baking powder Quick tip: Provides mild leavening through carbonation but less reliable; may slightly alter texture and moisture balance.
Club soda contains dissolved carbon dioxide which can introduce some aeration and lightness to the batter. However, it lacks the chemical leavening power of baking powder and is less consistent.
Use chilled club soda and mix gently to preserve carbonation. This method works best in recipes where minimal leavening is required.
The final tiramisu may be less airy and have a slightly different texture, but it can still maintain a pleasant lightness without introducing off-flavors.
