Everything is edible: fudge sticks for the railroad ties, vanilla wafers for the stepping stones, pretzels for the fence, crushed graham crackers for the paths, and crushed chocolate teddy grahams for the dirt in the beds. All other decorations are either fondant or gumpaste. Vines and flowers are buttercream. Cake is dark chocolate mayonnaise cake with vanilla buttercream icing. (For those who think mayo cake sounds a bit odd, or just downright disgusting, it takes the place of oil and eggs in the cake batter and is absolutely FABULOUS.)
