For my DH and Sister-in-Law's combined birthdays, I took inspiration from a wonderful Christmas cake that white7 posted recently. It had varied greens and whimsical trees. I loved the overall look and feel, but had some blue fondant on hand, so I converted that design to snowflakes.
3 layer - 9" marble cake with milk chocolate SMBC filling, and chocolate ganache under fondant. Fondant swirls, trim and snowflakes. Tappit letters on the board.
Thanks for looking, and thanks again white7 for inspiration - always love your cakes.
