Line a baking sheet with parchment paper.

Peel each banana and slice each in half lengthwise, then cut each half into two pieces for a total of 8 banana slabs.

Spread about 1/2 tablespoon of peanut butter over each banana piece.

Scatter chopped peanuts on top of the peanut butter layer and add a tiny pinch of sea salt.

In a microwave-safe bowl, combine the dark chocolate and coconut oil. Heat in 20-30 second bursts, stirring between bursts, until melted and glossy.

Spoon or drizzle the melted chocolate over each banana slice, covering the peanut butter.

Freeze the tray for at least 60 minutes or until the chocolate has set.

Let them sit at room temperature for 5 minutes before serving.
