I made this for my son's 1st birthday party tomorrow night. The Clubhouse itself is styrofoam covered in satin ice. I wasn't brave enough to try cake or RKT. The foam proved to be enough of a challege as it was. But the sheet cake is White Chocolate Raspberry, butter cream and Italian Cream cake. Our son insisted on standing in between me and the counter staring up at me as I decorated so my designed changed a bit but I am still pleased.
