This gorgeous white velvet cake has a soft, tender crumb. So what's the secret ingredient? Egg whites instead of whole eggs. White velvet cake has the same luscious texture and tangy flavor as red velvet cake, minus the red food coloring and cocoa. While many vanilla cakes are yellow-tinted, this white velvet cake recipe uses egg whites and buttermilk for a bright white crumb. Not to mention, every bite is light but also moist and as soft as velvet!
