I'm doing a Pixar Cars cake for a 2yr old and they wanted Lighting Mcqueen racing down a road with skid marks behind him. Is there anyway to make skid marks on buttercream? I know there was a way, but I can't remember. Thank you
I would just use straight black Americolor and paint them on with a soft brush. You'll have to use a soft touch to not damage the buttercream, but it should work well.
