I have one
Microwave chocolate cake
Put 4 tablespoons of flour, 2 tablespoons of sugar, 1 tablespoon of cocoa powder, and a pinch of baking powder in a bowl or mug and mix it. Add four tablespoons of milk, a tablespoon of olive oil, and a splash of vanilla extract. Mix it again. At this point you can take the spoon out and microwave it for 70 seconds BUT you can also add sprinkles, marshmallow paste, Nutella, cinnamon, or chocolate chips for filling and then microwave it
