White chocolate with raspberry filling - bottom tier; double chocolate fudge with caramel filling - middle tier, double chocolate fudge with chocolate ganache filling - top tier. All covered in fondant. Gumpaste snowflakes; but I ran out of time to cut out letters so had to do the name in buttercream.
The birthday girl's favorite color is blue, and she wanted a castle for a snow princess... Thanks to DGoettsche13 for inspiring me. Hopefully I will be able to do that inspiration some justice another time:)
