This is a recipe for easy gateau chocolat that can be made in the microwave using a silicone mold from Daiso. It only requires four ingredients: dark chocolate, unsalted butter, eggs, and milk, and can be made without using a knife. Melt the chocolate and butter in the microwave, mix, add the eggs and milk, mix further, pour into the silicone mold, and heat in the microwave. Let it cool slightly, then refrigerate until chilled, and you'll have a moist and rich gateau chocolat. It's also a great little gift.
