Line a 9x13 inch baking pan with parchment paper.
In a large pot over low heat, melt together the honey, peanut butter, and 3/4 cup butterscotch chips until melted smooth, about 5 minutes, stirring often. Remove from the heat. Add the vanilla, then stir in the corn flakes, tossing to combine. Spread the mix out into the prepared pan.
Melt the chocolate and 1 tablespoon coconut oil together in the microwave until melted. Pour the melted chocolate over the bars, spreading in an even layer.
Melt the remaining 1/2 cup butterscotch chips and 1 teaspoon coconut oil together in the microwave, stirring every 30 seconds until melted. Spoon small teaspoon size dollops of butterscotch onto the chocolate. Using a wooden skewer or the tip of a knife, gently swirl the butterscotch in a circular motion through the chocolate.
Transfer the bars to the fridge and chill 1 hour, until set. Top with salt, if desired. Let the bars sit at room temp 15-20 minutes before cutting, then cut into bars. Keep in the fridge until ready to serve.
