8" tier is yellow cake with strawberry buttercream filling. 6" tier is banana cake with caramel filling. All iced in vanilla Swiss meringue buttercream and covered/decorated with marshmallow fondant.
The customer sent me a picture of a One Direction cake that was black, white and red and had square tiers. I adapted it to round tiers, and the birthday girl wanted turquoise instead of red. And I really like how this one turned out!
Keep calm and bake on.
