I want to make these for my roomates for vday:

and I have this ice tray from Ikea (it's kind of rubbery/bendy) and I'm wondering if I can use that as a mold?? they're heart shaped, so I thought it would be perfect!! Also, am I suppose to buy the dark chocolate as a bar or as chips or what form? I've never made vegan candy before so this will be my first shot!
