She decided to have a different flavor for each tier.
They were:
Lemon slap tier, which is a lemon cake infused with vodka and a vodka buttercream frosting
Chocolate-chocolate chip bourbon infused cake with chocolate bourbon frosting
Vanilla cake with vanilla buttercream
WOO HOOO! So glad they enjoyed it.
And here is a pic of the final product!
Thanks again Corbie for placing the order.
