Top 5 tiers are Cream Cheese Buttercream icing & piping. Bottom tier is fondant. We have Sour Cream White with Cream Cheese Buttercream filling, Fresh Strawberry with Fresh Strawberry filling, Marble with Cookies-N-Cream filling and German Chocolate with Chocolate Buttercream filling. This was the biggest cake we've done to date and the first time for the ruffle technique. Thanks to Ashlee at Savannah Custom Cakes for her YouTube tutorial.
