A combination of red velvet cake and cream cheese yield a yummylicious to die for red velvet cake.  Hehe..  Pandai je aku.  This cake,  according to my kitchen tester aka iffah,  sangat sedap.  She loves it a lot!

2 teaspoon baking soda
6 teaspoons distilled white vinegar

1. Preheat oven to 350 degrees F. Line a standard 9x13" pan with liners.
2. On medium-high speed, cream the butter and sugar until light and fluffy, about 3 minutes. Turn the mixer to high and add the egg. Scrape down the bowl and beat until well incorporated.
3.Add cocoa powder, red colouring and vanilla to the batter and mix on medium speed until completely combined. You may need to stop the mixer to scrape the bottom of the bowl, making sure that all the batter gets color.
4. Reduce the mixer speed to low and slowly add half of the buttermilk. Add half of the flour and mix until combined. Scrape the bowl and repeat the process with the remaining milk and flour. Beat on high until smooth.
5. Again, reduce the mixer speed to low and add the baking soda and vinegar. Turn to high and beat for another couple of minutes until completely combined and smooth.
