Red Velvet made in home

Red velvet cake is a chocolate cake with either a red, bright red or red-brown color. It is traditionally prepared as a layer cake topped with cream cheese or cooked roux icing.
Common ingredients include buttermilk, butter, cocoa, and flour for the cake, beetroot or red food coloring for the color.
There’s also a scientific myth associated with Red Velvet Cake. It has sometimes been asserted that the cake’s red color comes from a chemical reaction between the baking soda and the chocolate in the recipe. This is the result of a simple misunderstanding of the chemistry involved. While cocoa powder contains anthocyanins (red vegetable pigments) they are only red in the presence of acids –they turn blue-green in the presence of bases. When cocoa is mixed with the baking soda, a base, the combination should turn the cake an unappetizing brownish-gray. It doesn’t, of course, because the anthocyanins are present in very small quantities, and any color shift is masked by the more prominent brown of the chocolate. The red color of the cake comes from a much simpler source: large amounts red food coloring.
The supposed red color resulting from the baking soda/cocoa combination also appears in connection with Devil’s Food Cake. I wonder if Red Velvet Cake was created because Devil’s Food Cake doesn’t look nearly as red as its name would suggest. This is akin to some folks adding green food coloring to Key Lime Pie because it doesn’t appear “limey” enough.
This is similar to the original recipe that began the red velvet craze. It was developed by the Adams Extract company in Gonzales, Tex. The original recipe, popularized in the 1940s, called for butter flavoring and shortening and is usually iced with boiled milk, or ermine, frosting.
