Wizard of Oz cake for my daughters 5th birthday. Bottom is two layer, 8 x 2 inch round (chocolate). Top is two layer, 6 x 2 inch round (confetti). The Emerald City is made of pretzel rods covered in melted white chocolate chips and I added green food dye while melting. Attached Emerald City to the cake with popsicle sticks, although my chocolate was a little messy so I couldn't push it all the way in. Not a great photo...cell phone photo taken at hotel.
