This was my daughter's 1st birthday cake! 6" round Wilton basic yellow cake recipe with butter extract -- delicious and moist! Twinkie 2 filling from here -- thanks Patty?!! Buttercream and MMF top/decorations I don't have an impression mat so I free handed it -- cut too deeply in spots Melted chocolate tiara -- instructions from here -- thanks!! Question: I have not used luster dust and would it paint well over chocolate?
