Red velvet is a reddish cake with a moderate cocoa flavour.
Useful to know
Red velvet is a reddish cake with a moderate cocoa flavour. King Arthur’s recipe includes cocoa, buttermilk or yogurt, and food colouring, with buttercream suggested for finishing. [1]
Other versions use different frostings, so there is no single universal coating. Separate colour from cocoa quantity when comparing recipes. A redder result does not prove a stronger chocolate flavour. Do not arbitrarily alter the liquid or leavening for colour alone, since both also contribute to structure.
