01 - Peel and slice the bananas. Place them in a blender along with Greek yogurt, honey (or maple syrup), and vanilla extract. Blend until smooth and creamy.
02 - In a microwave-safe bowl or over a double boiler, melt the dark chocolate with coconut oil until smooth. Stir to combine.
03 - Pour half of the banana mixture into popsicle molds, filling each mold about halfway. Drizzle a layer of melted chocolate into each mold. Gently swirl with a skewer or knife for a marbled effect.
04 - Top with the remaining banana mixture, then repeat chocolate drizzle and swirl as desired.
05 - Insert popsicle sticks. If using, sprinkle tops with chopped nuts or mini chocolate chips.
06 - Freeze for at least 4 hours or until fully set.
07 - To release the popsicles, briefly run the mold under warm water. Enjoy immediately.
