Melt the butter in a medium saucepan over medium heat.
Add the sugar, cream and ½ tsp salt and whisk until the ingredients are incorporated. Bring to a gentle boil and cook for 5 minutes, stirring occasionally.
Remove from the heat and add the vanilla extract.
Whisk to combine.
Taste the sauce; if you feel it still needs a little salt, sprinkle some more.
Serve the sauce warm or cool.
The sauce thickens a little as it cools, but it still remains soft enough that you can spoon it straight out of the fridge.
Store in airtight containers in the fridge for up to 2 weeks.
