This is a recipe for sweet potato pie that can be easily made using frozen pie crust and a microwave. After heating the sweet potatoes in the microwave, mix them in a bag with butter, sugar, and milk to make a paste, and sandwich it between rolled-out pie crusts. Brush with egg wash and black sesame seeds, twist, and bake in the oven to create a delicious snack with a crispy pie crust and fluffy, sweet potato filling that is a perfect match. It's perfect for potlucks and Christmas parties, and it tastes great even when cooled, as it can be reheated in a toaster oven.
