01 - Line a baking sheet with parchment paper to prevent sticking during freezing.
02 - Peel bananas and cut into 1/4-inch thick coins using a sharp knife.
03 - Place banana slices in a single layer on the prepared sheet, forming a rectangular shape for easier portioning later.
04 - Combine peanut butter, honey or maple syrup, and coconut oil in a small bowl. Whist until completely smooth and spreadable.
05 - Gently spread the peanut butter mixture evenly over all banana slices using a spatula.
06 - Place chocolate in a microwave-safe bowl. Heat in 20-second intervals, stirring between each, until fully melted and smooth.
07 - Drizzle melted chocolate over the peanut butter layer in an even pattern.
08 - Sprinkle chopped roasted peanuts and flaky sea salt over the chocolate while still wet.
09 - Transfer the baking sheet to the freezer and chill for at least 2 hours until completely firm.
10 - Break or cut the frozen bark into pieces. Serve immediately from the freezer for best texture.
