01 - Line a baking sheet with parchment paper for easy cleanup and prevent sticking.
02 - Peel bananas and cut crosswise into ½-inch thick rounds.
03 - Place banana slices in a single layer on prepared baking sheet. Freeze for at least 30 minutes until firm to the touch.
04 - Heat chopped chocolate in microwave-safe bowl at 20-second intervals, stirring thoroughly between each, until completely smooth. Alternatively, melt over simmering water in a heatproof bowl.
05 - Working quickly, remove banana slices from freezer. Spear each slice with fork or skewer and dip into melted chocolate, allowing excess to drip off.
06 - Return coated slices to lined baking sheet. Immediately sprinkle with chopped nuts, coconut, or sprinkles while chocolate is still wet.
07 - Freeze for 15 minutes or until chocolate coating is completely set.
08 - Enjoy immediately while frozen or allow to thaw for 2-3 minutes for softer texture.
