An all-American side dish and Thanksgiving Day staple, Sweet Potato Casserole is always a crowd-pleaser. Ours begins with heaps of mashed sweet potatoes, drizzled with maple syrup and a splash of Maker’s Mark bourbon, blended into a rich coconut-oat milk. True to casserole tradition, we finish this velvety smooth flavor with three toppings—candied pecans, brown sugar oatmeal streusel, and ripples of vanilla-bourbon sweet potato—for an extra nutty crunch.
