I'm doing my first gold drip cake, and I'm wondering if pouring melted ganache (from 2 parts candy melts/1 part heavy cream ) on top of the buttercream will melt or mess up the buttercream? Should I freeze the buttercream-iced cake first before dripping the ganache? And will the Wilton brand gold luster dust with Vodka show up enough if painted on the ganache? I am out of the other brand of gold luster dust and need to do the cake asap. Advice??? TIA!
Make sure your cake is super cold and BC is crusted hard. Let the drip be warm enough to pour, it will harden as soon as it hits the cake. I start in the middle of the top of the cake and use a big spoon to run off the edges. You can also use a piping bag or a squeeze bottle to control your drips. The candy coating should be ok to paint. I always use ganache and it paints well candy coating can sometimes be tricky to paint for me anyway.
Hope this helps
