Microwave the milk and chips for 1 minute.

Stir until smooth adding 15 seconds at a time back in the microwave if not smooth.

Pour into an 8x8 pan lined with parchment.

No need to spread it to corners-it will be thicker if you don't.

Let it set up-can place in fridge.

Cut into squares and spread caramel in between 2 squares.

Sprinkle with coarse sea salt, if desired.
