This recipe video shows how to make moist and rich bite-sized sweet potatoes using just three ingredients: sweet potatoes, vanilla ice cream, and egg yolk to brush on top. Peel the sweet potatoes, heat them in the microwave, and mash them while still hot. Add the vanilla ice cream and mix to make a smooth mixture. Shape the mixture into squares and cut them into bite-sized pieces. Brush the surface with egg yolk and bake in a toaster oven to complete the sweet potatoes with a golden-brown color. It's an easy and delicious treat that's perfect for a home cafe or as a gift.
