Peel and slice the ripe bananas into 1/4-inch thick rounds and arrange them on a parchment-lined baking tray.

Spread a layer of creamy peanut butter over each banana slice.

Melt dark chocolate in a microwave-safe bowl in 30-second intervals, stirring until smooth.

Drizzle melted dark chocolate over the peanut butter-covered bananas.

Sprinkle crushed peanuts over the melted chocolate layer.

Place the tray in the freezer for at least one hour to set.

After freezing, cut the bark into bite-sized pieces.
