A professional chocolatier is sharing a recipe for an exquisite chocolate cake that can be easily made at home, as a special feature just before Valentine's Day. It uses simple ingredients such as unsalted butter, granulated sugar, chocolate, eggs, and cake flour, and is full of easy-to-make tips, such as using a microwave instead of a double boiler for the chocolate. Simply mix the butter and sugar, then add the eggs, melted chocolate, and cake flour in order and mix, then pour into a mold and bake in the oven. Depending on the baking time, it can also be made into a fondant au chocolat, and you can enjoy various arrangements such as serving it with ice cream or jam. This moist and rich chocolate cake is recommended even for beginners in baking.
