This is a recipe for a moist and rich chocolate cake that can be made using only four ingredients and a microwave. Break a chocolate bar into small pieces, combine with vegetable oil and heat in the microwave, then add the egg and milk and mix well. Pour the mixture into a mini loaf pan from Daiso, heat in the microwave, then chill in the refrigerator until firm. Decorate with whipped cream and freeze-dried strawberries, and you'll have a perfect single-serving chocolate cake that makes a great gift.
