Hi Sjak, I'm also new to this forum, but I recently found a good Red Velvet Cake recipe on the BBC website:
Its actually for a three tiered wedding cake, but it lists the ingredients for each tier seperately, so it easy to make just one. I used sponge flour instead of the plain flour and baking soda. I also used a cream cheese buttercream to cover and fill the cake. The final product tasted delicious.
