⭐ Buttermilk and Baking Soda (Best Vegan Option)
1/4 cup buttermilk + 1/2 teaspoon baking soda per eggButtermilk provides acidity and moisture, which when combined with baking soda, produces carbon dioxide gas that helps the cake rise, mimicking the leavening effect of eggs. This combination also enhances the characteristic tang of Red Velvet Cake. The acid-base reaction is crucial to maintain the cake’s tender crumb and vibrant color.
For best results, add the baking soda directly to the dry ingredients and mix the buttermilk with the wet ingredients to ensure even distribution. Use fresh buttermilk to maximize acidity and leavening power. Avoid overmixing to prevent a tough crumb.
Compared to eggs, this substitute maintains a similar rise and moistness but may yield a slightly more tender crumb with a subtle increase in tanginess, which complements the traditional flavor profile.
