This gorgeous, flavor-packed sweet potato pie is truly majestic. A zesty blueberry sauce dials up the vibrancy of this decadent dessert, but the deep purple hue comes primarily from purple sweet potatoes in the filling. Their creamy composition makes for a velvety smooth texture, and their subtle sweetness is enhanced with lime zest and a little sugar. The homemade pie crust, which features the warming flavors of walnuts and cinnamon, provides the perfect base for the no-bake filling. Simply chill it in the fridge, add the blueberry sauce, and give yourself the royal treatment by enjoying a big slice.
