Lightly spray the bottom of a 8"x8" glass baking dish with cooking spray and line the bottom with parchment paper. Then spray the baking dish again.

Set a large bowl over a saucepan of simmering water and add the chocolate spread. Once it has melted, stir in the crispy rice cereal until completely incorporated.

Transfer the mixture to the lined pan and press the mixture in tightly with a spatula.

Dust the top liberally with sea salt.

Cover the pan and chill completely until firm, at least 6 hours.

Break the bars into large chunks and enjoy!
