Instructions
Preparation Steps
In a medium saucepan, whisk together heavy cream, light corn syrup, brown sugar, cocoa powder, and flaky sea salt.
Set over medium heat and bring to a gentle bubble, whisking often until smooth and the sugar dissolves, about 3 to 4 minutes.
Remove from heat and add chopped bittersweet chocolate and butter. Let sit 30 seconds, then whisk until fully melted and silky.
Return the pan to low heat and cook, stirring, until the sauce thickens slightly and coats the back of a spoon, about 2 to 3 minutes. Do not boil.
Remove from heat and stir in vanilla. Taste and adjust salt to preference.
Serve warm over ice cream or desserts. Sprinkle with a pinch of additional flaky sea salt before serving. Store leftovers in the refrigerator up to 2 weeks; rewarm gently.
Notes
For a glossier finish, add 0.5 teaspoon espresso powder with the cocoa to boost chocolate flavor. If the sauce thickens too much after chilling, whisk in 1 to 2 tablespoons warm cream while reheating.
