This recipe creates a rich, decadent hot fudge sauce with just four pantry staples: sugar, cream, dark cocoa, and salted butter. Ready in minutes, it's perfect for topping desserts. The sauce thickens upon cooling but can be easily reheated for a velvety smooth consistency, offering a generous yield for future indulgences.
For the best flavor, use a high-quality dark cocoa powder; this is the primary flavor component. Stir the mixture constantly over medium heat to prevent scorching at the bottom of the pot and to ensure a smooth, homogenous emulsion. If using unsalted butter, add a generous pinch of salt (approximately 1/4 teaspoon) to the mixture to balance the sweetness and enhance the chocolate notes. To elevate the sauce, consider adding a teaspoon of vanilla extract or a pinch of espresso powder after removing it from the heat. When reheating, always use low heat and stir gently to prevent separation or burning.
