In a small saucepan, combine the heavy cream and granulated sugar. Heat the mixture over medium heat until it starts to simmer, stirring occasionally to dissolve the sugar.
Once the cream is simmering, remove it from the heat and add the semi-sweet chocolate chips, cocoa powder, vanilla extract, and salt.
Whisk the mixture until the chocolate chips have fully melted and the sauce is smooth and glossy. If necessary, return the saucepan to low heat to help the chocolate melt more easily.
Once the chocolate sauce is well combined, remove it from the heat. Let it cool slightly before transferring it to a storage container or serving it warm.
Serve the chocolate sauce drizzled over desserts like ice cream, pancakes, or fruit.
For a richer sauce, you can use dark chocolate chips instead of semi-sweet.
This chocolate sauce can be stored in the refrigerator for up to a week. Reheat it gently in the microwave or on the stovetop before serving.
Feel free to experiment by adding a splash of coffee for a mocha flavor or a pinch of cinnamon for a hint of spice.
