150g Butter, chopped
250g Brown sugar
1 tsp Vanilla extract
½ teaspoon Salt (i prefer to have a bit of salt to counteract some sweetness but this is optional)
To make the caramel sauce place all ingredients into the thermomix bowl and cook 7min/Varoma/speed 2, placing simmering basket instead of measuring cup onto mixing bowl lid.
Note: Mixture will be foamy once finished, but will settle when cooling. Transfer into a sealed container and allow to cool to room temperature before placing into the fridge.
