The cake was made by 4 layers of  Chocolate Chiffon Cake, each layer was 8"x8", filled and crumb coated with Chocolate Buttercream Frosting, and then covered and decorated with Marshmallow Fondant.

I made two batches of Marshmallow Fondant. Each with
1 package (16 ounces) white mini marshmallows (use a good quality brand)
2-5 tablespoons water

The fondant was made two days ahead. I then tinted one batch light brown to cover the whole cake, and
tinted some fondant different shade of green, brown, and blue.
