I'm making a red velvet cake and want to do a black drip down the sides, like the eerie Nightmare Before Christmas Halloween cake. Can I get some suggestions on how to make this look the best? I haven't had a lot of success with a nice drip effect with ganache. Also, should I use buttercream or fondant under it in white? Thanks!

The way how I learn how to do mine, is to melt the chocolate in a piping bag, and then run it over the cake very close to the ends and it causes the drip effect, I am also a member of yummyarts.com you can join and you get a 30 day free trial, and after that you don't have to continue if you don't want to pay the monthly fee. that is where I learned to do mine.

I have a very bad (but you'll get the idea) youtube video that shows how I do my chocolate drips. You can use candy melts and do the same thing I imagine. Might have to thin a bit with shortening.

Pretty much what Lisa is showing.

Thank you Lisa. That is exactly what I needed to see. I appreciate you posting the video.

I USE WARMED CANNED ICING. I USE CHOCOLATE AND ADDBLACK TO GET A GOOD DEEP BLACK, OR WHITE WITH OTHER COLORS. I JUST WARM IT IN THE MICROWAVE UNTIL IT'S SMOOTH AND POURABLE, NOT HOT OR IT WILL MELT THE BUTTERCREAM, JUST WARM TO THE TOUCH AND POURABLE. FIRST FILL A BAG WITH SOME FOR THE EDGES TO HAVE READY, THEN, I POUR SOME ON THE TOP AND SMOOTH WITH A SPATULA TO THE EDGE THE USE THE BAG TO GO AROUND THE EDGE, IF DONE QUICKLY ENOUGH, IT IS SEAMLESS. BEST WISHES ON YOUR CREATION

Best thing I did was to pour my warm ganache in a squeeze bottle (a Wilton one) and just run it around the edge of my cake. The bottle gave me so much more control than a piping bag. The opening at the tip was I want to say a medium size. You want the ganache to run freely. Then fill in the top of the cake so it looks like it dripped over the sides.

do you think it will work to do this over fondant or do I need to use buttercream icing?
