The main ingredient in a chocolate soufflé is chocolate. Typically made with dark or semi-sweet chocolate, the soufflé combines melted chocolate with egg yolks and sugar, creating a rich base. Egg whites are beaten to form stiff peaks and folded into the chocolate mixture to give the soufflé its light and airy texture. When baked, the soufflé puffs up beautifully, creating a delicate exterior and a soft, molten center. It’s a classic French dessert often served warm and dusted with powdered sugar, making it a popular choice for special occasions.
