01 - Line a baking sheet with parchment paper and set aside.
02 - Peel the bananas and cut them into 1/2-inch thick rounds. Discard the peels.
03 - In a small bowl, combine the Greek yogurt with honey (or maple syrup) and vanilla extract, if using. Stir until smooth and well blended.
04 - Dip each banana round into the yogurt mixture, turning to coat all sides evenly. Use a fork or toothpick for easier handling.
05 - Place each yogurt-coated banana slice onto the prepared parchment-lined baking sheet, spacing them slightly apart to prevent sticking.
06 - Sprinkle your choice of chopped nuts, shredded coconut, or mini chocolate chips over the coated banana slices while the yogurt is still wet.
07 - Place the baking sheet in the freezer for at least 2 hours, or until the yogurt bites are completely firm and frozen through.
08 - Transfer the frozen banana yogurt bites to an airtight container and keep stored in the freezer until ready to serve.
