Place a single cake on the bottom of your serving platter
Create a dam around the top of the cake with vanilla buttercream then fill the dam with cranberry curd. Repeat the process for the second layer.
Place the third cake on top of the second layer
Remove 1 cup of vanilla frosting and place it in a small bowl. Thin the frosting with 2-3 tablespoons of water and ice the top and outside of the cake with the thin vanilla buttercream. This is your crumb boating
Let the crumb coating dry from 30-60 minutes then frost the outside of the cake with the remaining, thicker, vanilla butter cream.
Decorate the cake with the sugared cranberries and fresh herbs, if using
