Red Velvet cake

Made this cake for my hubby's birthday last year and it really turned out well. the velvety texture was simply superb. Actually I learnt this recipe from foodnetwork a complete site for all food related queries. Thought posting this recipe now would be perfect for the ocassion. Sending it to the announcing-hearts-for-st-valentines-day event hosted by Priya
