I made Japanese sweet potato cakes at home today. The ingredients are some sweet potatoes, butter, milk, sugar, and a little salt. It's very easy and simple. Mash the boiled sweet potatoes, mix with the other ingredients, shape them into small sweet potatoes and bake them. It takes about 30 minutes. Homemade sweet potato cakes are lower in calories than other snacks and my children enjoyed eating them, so I'm going to make sweet potato cakes again😊
