red velvet 10 inch layer cake covered in mirror glaze. I use buttercream under the glaze and do not use the gelatin part that is shown in most of the videos on the mirror cake technique. If you get the buttercream smooth enough...I used the Viva towel technique...it worked fine. The temperature is key in using this stuff and if you line your catch pan with parchment, you can save the left over run off for later use. It can be a pain but it beats all of the waste.
