1 to 1½cupssemisweet chocolate chips or chopped semisweet chocolate
Instructions
Preheat oven to 350 degrees F. Line a large rimmed sheet pan with parchment paper and spread cereal evenly over it.
Put the butter in a medium size saucepan and melt it over medium heat.
Add the brown sugar and salt, stirring to combine. Cook for about 5 minutes or just until mixture is dark brown and has begun to bubble,
Remove from heat, stir in the vanilla, then drizzle the hot mixture over the cereal, spreading as evenly as you can with a scraper.
Bake for only about 5 minutes, then remove from oven and sprinkle chocolate over the top. Let the chocolate soften for about 5 minutes, then use a spatula to spread it over the candy.
If desired, sprinkle lightly with extra sea salt. Chill to set the chocolate, then break into large chunks.
