In a food processor, blend base ingredients until crumbs look like wet sand. Press base mixture into a compact layer in prepared loaf pan.
Add caramel ingredients into the same food processor and blend until smooth. Use a spatula to scrape down the sides a few times.
Evenly spread the caramel over the base layer. Freeze for at least 1 hour before cutting into 8 bars.
In a small bowl, mix all the chocolate coating ingredients until smooth.
Arrange bars at least 1 inch apart on a piece of wax or parchment paper. Spoon the chocolate coating mixture over the surface of each bar. Garnish with a pinch of Maldon sea salt.
Return bars to the freezer for at least 15 minutes, or until chocolate coating has hardened.
Store bars in the freezer. Best eaten straight from the freezer!
