White Velvet Cake is a soft, delicate cake with a hint of buttermilk and vanilla. White velvet cake is basically red velvet without the red. It’s a buttermilk cake base that results in a VERY soft, fluffy and moist cake. If you leave out all the color and the cocoa powder you have yourself a nice white velvet cake. Neat huh. The buttermilk gives this southern inspired cake it’s rich and velvety texture.
