I have someone who wants a Clue themed cake (the gameboard in fondant) on top of a giant cookie. I've never really done a giant cookie cake, especially a square one. I'm just wondering if it's even possible and how to make sure I can get it out of my pan without breaking it.
Any tips or ideas would be so helpful! Here is a picture of a cake version. I feel confident with the fondant work, but just not sure about the cookie. Thanks so much!
