We’re all obsessed with chalkboard paint (seriously, you can turn anything into a chalkboard!), but this cake takes it to a whole new level with chalkboard icing. That’s right, icing. That’s a chalkboard. That you can eat. It’s actually just black fondant, but it's written on by cool homemade sugar chalk that seems easy enough to make. Guests can even write little messages for the birthday boy or girl when they enter the party.
