This video introduces a recipe for a rich, crispy chocolate cake that can be easily made using only three ingredients: six Lotte Choco Pies, 60g of milk, and 100g of chocolate bar, utilizing only a microwave and refrigerator. By mixing the Choco Pies and milk, heating it in the microwave, letting it cool and harden, and then coating it with melted chocolate, you can create a rich cake with a two-layered texture that is crispy on the outside and moist on the inside. Since no oven is used, it is recommended for beginners in baking and is perfect for making at home or as a gift.
