Method
- Gather all your ingredients, then line a baking pan with parchment paper to prevent sticking.

- Pour the sweetened condensed milk, butter, and sugar into a heavy-bottomed saucepan. Turn the heat to medium and stir constantly until the mixture begins to melt and combine smoothly.

- Continue stirring as the mixture heats up, feeling it thicken and shimmer, and listening for a gentle bubbling sound. Watch for the mixture to turn a rich caramel color, about 8-10 minutes.

- Insert a candy thermometer and cook until the temperature reaches 115°C (240°F), or until the mixture reaches the soft ball stage. Remove from heat immediately once this temperature is reached.

- Quickly stir in the vanilla extract and sea salt flakes, then add the chocolate chips if using. Mix vigorously for about 2 minutes until the mixture is glossy and smooth.

- Pour the hot fudge into your prepared pan, spreading it evenly with a spatula. Let it sit at room temperature without disturbance for at least 2 hours, or until fully set and firm.

- Once the fudge is firm and shiny, use a sharp knife to cut into squares. Enjoy the chewy, velvety richness of this decadent treat.

Notes
For a richer flavor, try adding a splash of coffee extract or sprinkling sea salt flakes on top before setting.
